Definitions
- the present invention relates to the field of the packaging of containers in batches. It relates to a compact batch of grouped containers, a retaining strip intended to form said batch and a method implementing this batch.
- the container is a bottle or a flask.
- a container is intended to contain, in a non-exhaustive manner, a fluid, a liquid, powders or granules, in particular of the food-processing or cosmetic type.
- the containers can receive several different successive treatments, such as the manufacture of the container, for example during a plastic injection or stretch-blow molding operation in the case of a plastic bottle, followed by filling then closing with a cap and labelling. At the end of these treatments, the containers are said to be "finished".
- each batch comprises several containers, brought together for example in a matrix arrangement, generally of generally parallelepipedic shape, often square or rectangle, according to columns and rows.
- a typical batch groups together six containers in two rows and three columns.
- each group is coated, in particular covered with a film, in order to hold the containers together and to facilitate the handling of such a batch thus obtained.
- Such encapsulation can be carried out through a step of filming or preferably wrapping.
- wrapping a group of containers consists of wrapping it with a sheet of plastic film made of heat-shrinkable material.
- a coated group then undergoes a heating step so that the sheet conforms to the overall external shape of the containers.
- the sheet of film shrinks under the effect of heat to form a constriction ensuring the maintenance of the grouped containers.
- the grouping of the containers, the coating and the heating are carried out by means of a dedicated installation of the bundler type, through several successive stations.
- Such a heating operation represents a significant energy expenditure.
- Such a packaging solution not only involves significant energy consumption from a financial point of view, but is also harmful to the environment.
- the coating is carried out from a film of plastic material, essentially obtained from the petrochemical industry. However, almost half of the plastic waste found in the sea is single-use plastic objects.
- patent US5570787 proposes keeping containers grouped together to form a batch, in particular by surrounding the containers with a wide band of elastic plastic.
- This band covers a large portion of the height of the products.
- the batch formed and surrounded is held by a lateral elastic strap, affixed to the outer contour of the containers, but also by a complementary strap, forming the handle, which holds the batch by the bottom of the containers.
- the handle and the side strap cooperate to allow the containers to be held together.
- This alternative certainly has the advantage of substantially reducing the total amount of plastic used but remains harmful to the environment, the two straps surrounding the lot being both made of elastic plastic material.
- DE102011107265 proposes to connect the containers together by means of glue dots and to finalize the maintenance using an adhesive or self-adhesive band coming to encircle the lot.
- the self-adhesive strip is preferably transparent, placed at the level of the label of the products, to enable the consumer to view the information present on the label.
- This strap can be made of a composite material, that is to say composed of several different materials. It therefore has the disadvantage of being little or even not recyclable given the difficulty of separating so-called recyclable materials from other materials. Furthermore, it has another drawback, because when it is removed it risks damaging the label present on the container, insofar as it is self-adhesive.
- the invention thus aims to provide a holding device that is reliable, solid and ecological, both in its composition and in the quantity of waste generated.
- the environmental impact of the invention is greatly reduced compared to packaging using plastic material.
- the invention proposes a solution consisting in holding the containers integral with each other, in the form of a batch, with at least one strip of paper affixed at the level of a flat portion of each of the containers. This positioning of the band guarantees the solidity of the batch: the band does not slip and exerts adequate pressure on the wall of the containers.
- the subject of the invention is thus a batch which comprises at least two containers, and at least one closed band which keeps them grouped together, said containers possibly being provided with a label, said containers each having a body and a bottom, aligned in a main direction, the body having at least one planar portion.
- the lot is characterized in that said at least one strip is made of paper, has a height less than or equal to the height of said flat portion and is affixed around the lot at the level of said at least one flat portion of each of said containers, so as to form a contact zone between said flat portion and said at least one strip of paper.
- the invention also relates to a paper holding strip for a batch as defined above.
- the invention also relates to a method for implementing said batch, according to which at least two containers are grouped together.
- the batch is coated with at least one strip at the level of the at least one flat portion of each of said containers,
- At least one band is affixed with sufficient tension to hold said at least two containers together.
- FIG. 1 schematically represents a perspective view of a batch, showing in particular a square matrix distribution of four containers, the containers of said batch being of the bottle type, of generally rectangular shape and said containers being surrounded by a strip of paper material ;

- FIG. 16 schematically represents a perspective view of a batch comprising three sub-batches of two products each, showing in particular a handle on the central sub-batch, during coating;
- FIG. 17 schematically represents a view similar to FIG. 9, showing in particular a strip of paper covering the batch, and a strip of paper surrounding the sub-batch, said strip and said strip being positioned on different flat portions;
- FIG. 18 schematically represents a simplified view of an example of architecture of a line for packaging batches of products according to the invention.
- the invention thus firstly relates to a batch 100 which comprises at least two containers 1, and at least one closed strip 2 which keeps them grouped together, said containers 1 possibly being provided with a label 14, said containers 1 each having a body 3 and a bottom 4, aligned in a main direction 15, the body 3 having at least one flat portion 5.
- the container 1 is a bottle or a flask. It can be made of any material, in particular plastic or even glass. Preferably, the container is made of polyethylene terephthalate, hereinafter PET.
- PET polyethylene terephthalate
- the container 1 can therefore be rigid or semi-rigid. It is intended to contain a fluid, a liquid, powders or granules, in particular of the food-processing or cosmetic type.
- the container 1 can have any type of shape, symmetrical or not. It may have a rounded section, generally of circular or ovoidal shape, or else of polygonal section, in particular rectangle or square. Preferably, said containers have a rounded section, in particular generally circular.
- the containers can receive several different successive treatments, such as the manufacture of the container, for example during a plastic injection or stretch-blow molding operation in the case of a plastic bottle, followed by filling then closing with a cap and labelling. At the end of these treatments, the containers are said to be "finished".
- the container 1 may optionally have a label 14.
- Said label 14 may be affixed to the body 3 of the container 1, or be attached at the level of the neck of the said container 1, in the form of a ticket.
- the label 14 can also be in the form of a retractable sleeve, which will match the shape of said container 1.
- the label 14, when present, has the function of delivering information on the contents of the container 1 , or even an advertising message, a logo, a bar code.
- Each batch therefore comprises several containers, brought together for example in a matrix arrangement, generally of generally parallelepipedic shape, often square or rectangle, in columns and rows.
- the containers When they are packaged, the containers can also be staggered.
- the staggered lot can have different advantages.
- the staggered arrangement notably offers more points of contact between the grouped products. Furthermore, the additional friction between the containers will increase the strength of the batch.
- the staggered arrangement also makes it possible to optimize the space between the containers, and therefore represents a gain in storage capacity. It is then possible to stack more batches on a pallet.
- the containers 1 have a body 3 and a bottom 4. In a normal orientation, the container 1 rests on its bottom 4.
- the bottom 4 can be flat or petaloid in shape.
- the body 3 comprises a peripheral wall 7.
- the term “compact” corresponds to a batch 100 in which containers 1 are brought together and positioned side by side, joined to each other during their grouping according to one of the configurations described.
- the containers 1 are held together by a closed strip 2, that is to say that said strip 2 coats all of the containers, being affixed against a portion of the peripheral wall 7, to form a batch 100.
- a closed strip 2 that is to say that said strip 2 coats all of the containers, being affixed against a portion of the peripheral wall 7, to form a batch 100.
- the containers 1 grouped and coated they are then integral with each other, integrally forming a batch 100.
- the containers 1 of such a batch 100 are then inseparable, except to voluntarily dismantle said batch 100 to extract one or more containers 1.
- Container 1 has at least one flat portion 5. At said portion 5, peripheral wall 7 of body 3 extends substantially parallel to main direction 15.
- the flat portion 5 has a lower limit 18 and an upper limit 19.
- the lower limit 18 of the flat portion 5 is the edge which is located at the smallest height. relative to the total height of said container 1, starting from the bottom 4 of said container 1, in the main direction 15.
- the upper limit 19 therefore corresponds to the edge of said flat portion 5 which is located at the greatest height relative to the total height of the container 1, starting from the bottom 4.
- the flat portion 5 represents a section of the peripheral wall 7, of the body 3, extending between a lower limit 18 and an upper limit 19.
- the perimeter of container 1, or its diameter when said container is circular in shape can vary along its height.
- the body 3 At the level of the flat portion 5, the body 3 has a shape close to that of a cylinder based on a circle, and in particular sufficiently close to such a cylinder of revolution for the strip 2 which is affixed to it to exert sufficient force. to hold the containers 1 together.
- the flat portion 5 can for example be located at the level of a right cylinder: the diameter of the bottle at the level of the upper limit 19 of the flat portion 5 is equal to the diameter of the bottle at the lower limit 18 of said portion.
- the difference in diameter between the lower limit 18 and the upper limit 19 of the flat portion 5 is at most 10mm (millimeters) every 100mm.
- said difference in diameter is less than or equal to 4mm every 100mm.
- the container 1 can for example comprise sections of conical shape, and the planar portion 5 can be located at the level of such a section, insofar as the conical shape does not widen or shrink. beyond a certain angle, which corresponds to 10mm every 100mm, preferably 4mm every 100mm.
- the difference in perimeter between the lower limit 18 and the upper limit 19 of the flat portion 5 is at most 10mm every 100mm , preferably equal to or less than 4mm every 100mm, in order to guarantee the cohesion of batch 100 in an optimal manner.
- the flat portion 5, at the level of the contact zone 6, extends in a direction parallel or substantially to the main direction 15.
- the body 3 of the container 1, at the level of the flat portion 5, optionally has the shape of a right cylinder.
- the tension exerted by the strip 2 of paper forming the batch 100 is then distributed evenly over the whole of the flat portion 5.
- the container 1 may have several flat portions 5.
- the batch is characterized in that the at least one strip 2 is made of paper, has a height less than or equal to the height of said flat portion 5 and is affixed around the batch 100 at the level of said at least one flat portion 5 of each of said containers 1, so as to form a contact zone 6.
- the flat portion 5 therefore comprises a contact zone 6.
- This contact zone 6 represents the contact surface between the at least one strip 2 of paper and the peripheral wall 7 of the body 3 at the level of the flat portion 5.
- the zone of contact 6 therefore corresponds to the effective surface against which the strip 2 of paper is affixed against the peripheral wall 7.
- the interaction between the strip 2 and the peripheral wall 7 at the level of the flat portion 5 forms the contact zone 6.
- the contact zone 6 corresponds to a quarter turn for a bottle located in a corner of the lot 100.
- the contact zone 6, formed by the affixing of the strip 2 to the peripheral wall 7, corresponds to a line contact in the main direction 15.
- the strip 2 is made of paper, that is to say it is composed mainly or mainly of cellulose fibers.
- paper falls within the specific field of container packaging 1 and is limited to wrapping paper.
- paper excludes cardboard, corrugated cardboard, and cartonboard.
- such paper is based on cellulose fibers.
- the paper used in the invention may be kraft paper or a derivative of kraft paper.
- the band is made of a paper having increased strength, an appropriate breaking limit, due to its manufacturing process.
- the resistance or the extensibility of the paper are characteristics which can be improved during the manufacturing process, for example by adding a weft, or specific fibers.
- the fibers can also be oriented in the longitudinal or transverse direction, to improve the resistance to elongation before rupture according to the direction of orientation.
- the strip 2 of paper consists mainly of biodegradable and/or recyclable components.
- the positioning of at least one strip 2, made of paper, contributes to the solidity of lot 100.
- said contact zone 6, formed by the affixing of the strip 2 of paper to the peripheral wall 7 of the container 1 at the level of the flat portion 5, extends over at least 50% (percentages ) of said flat portion 5, preferably at least 70%, in the main direction 15.
- the at at least one strip 2 of paper must be in contact with the peripheral wall 7 over at least 50% of said flat portion 5, preferably at least 70%, so as to form an adequate contact zone 6.
- the contact area must be large enough to guarantee the cohesion of the grouped containers. This is all the more necessary because of the material from which the strip 2 is made, paper being less extensible and less resistant than plastic.
- a strip 2 of paper which would only hold the containers together by the tension exerted, on only a few points of the latter , would be highly susceptible to tearing: during their handling or transport, rubbing and friction between the containers would strongly stress the bearing areas.
- This feature has the advantage of contributing to the strength of the batch 100, and preventing any risk of dislocation of said batch, for example by breaking the strip 2 of paper.
- batch 100 comprises a single strip 2 of paper. This has the advantage of further minimizing the amount of waste produced, while maintaining optimal maintenance of batch 100.
- said strip 2 of paper has a minimum height of one eighth of the height H of each containers 1 along the main direction 15.
- said strip 2 of paper has a minimum height of a quarter of the height H of each of the containers 1 along the main direction 15.
- the strip 2 of paper has a height less than or equal to the height of the flat portion 5. Furthermore, according to certain embodiments, the strip 2 of paper does not extend below the lower limit 18 and above the upper limit 19, along the main direction 15: it is then entirely included in the section of the plane portion 5.
- the batch 100 comprises at least two strips 2 along the main direction 15, the cumulative total height of said strips representing at least a quarter of the height H of the containers 1.
- the cumulative height of said strips represents at most two-thirds of the height of each of the containers 1 along the main direction 15.
- the considered height of a container 1 is its height H measured between the top of the stopper 22 and the contact surface of the bottom 4 of said container 1
- the height H of a container 1 and the height of a strip 2 are measured along the main direction 15.
- the at least two strips 20 and 21 of paper are arranged along the main direction 15. They can rest on the same flat portion 5 or, preferably, on two separate flat portions 51 and 52.
- the at least one flat portion 5 comprises grooves 8, said grooves 8 covering less than 50% (percents), preferably less than 30%, of the flat portion 5.
- a container 1 can in fact have grooves 8, for aesthetic or technical purposes, of any shape or pattern, these grooves 8 going around the body 3 of the container or not and being distributed homogeneously or not, symmetrical or not. .
- a container 1 can also present on its body reliefs, textures, also for aesthetic purposes, or for informative purposes.
- a container 1 can also have grooves, or belts, for technical purposes. These grooves 8, patterns, grooves or belts must not represent more than 30% of the surface of the flat portion. Indeed, the contact zone 6 between the strip or strips 2 of paper and the peripheral wall 7 of the container must preferably represent at least 70% of the flat portion 5, in the main direction 15
- a section of the peripheral wall 7 having grooves 8, in the main direction 15, can be considered as a flat portion 5, if the surface of the grooves 8 does not cover more than 30% of the surface of said section.
- grooves 8 or reliefs, or even grooves or belts are not taken into account in the calculation of the diameter or the perimeter of the container 1, between the lower limit 18 and the upper limit 19 of the flat portion 5, insofar as their dimensions do not exceed 10mm (millimeters) in depth every 100mm, preferably 4mm in depth or elevation over a section of more than 8mm in height.
- a groove, a relief or a pattern must not have a depth or an elevation of more than 10mm (millimeters) on a section of more than 8mm in height in the main direction 15 .
- the lower 201 and upper 202 edges of the strip 2 of paper do not rest on a relief or in a groove 8 but directly on the contact zone 6 at the level of the peripheral wall 7.
- the batch 100 comprises at least four containers 1, at least one sub-batch 101 comprising at least two of said containers 1, at least one strip 13 of closed paper which holds together said containers 1 forming the sub-batch 101, at least one closed strip 2 of paper coating said batch 100 at the level of a flat portion 5 of each of said containers 1, so as to form a contact zone 6 between said flat portion 5 and said at least one band 2.
- Such a configuration is particularly advantageous, the solidity of the lot 100 being reinforced. Indeed, in the case where more than four containers 1 are grouped together, the total contact area 6 is reduced for some of the containers 1. In particular, the containers 1 located in the center of the batch will tend to slide against the walls of the containers 1 located at the corners of lot 100. This phenomenon is all the more important when the containers have a rounded section, generally circular or ovoid, which is more in the case of plastic containers. In such a case, the batch 100 undergoes deformations which is likely to lead to its dismantling during its handling. Furthermore, it is understood that the strip 2 of paper covers a smaller portion of the peripheral wall 7 of the containers 1 located in the center of the lot 100, compared to the containers 1 located in the corners of said lot 100.
- each sub-batch 101 can bring together at most four containers 1.
- Each sub-batch 101 can extend transversely, that is to say along the columns of the batch 100, or even longitudinally, it i.e. along the rows of said lot.
- the sub-batch or batches 101 will advantageously be oriented according to the number of containers 1 forming the batch 100, in order to optimize its solidity.
- a sub-batch 101 is composed of at least one container 1 having a large contact zone 6, for example one or more containers 1 located at an angle of the batch 100, and of at least one container 1 having a reduced contact area 6, for example one or more containers 1 located in the center of said lot 100. It is understood that here the maximum possible contact area 6 is linked to the location of the container 1 at the within batch 100.
- Each sub-batch 101 will ensure that the containers 1 component are kept together. As part of the handling or transport of the batch 100 thus formed, the sub-batches 101 will minimize the relative friction and the displacement of the containers 1, in particular the containers located in the center of said batch 100.
- each container 1 will then be firmly held, either directly, by means of the at least one strip 2 of paper, or by means of a double coating, that is to say directly by means of the at least one strip 13 of paper and indirectly by means of the means of the at least one strip 2 of paper. It is understood that depending on the number of containers 1, it is not always necessary to surround all the containers 1 in the form of a sub-batch 101 prior to the coating of a batch 100. other words, in certain embodiments, certain containers 1 are not surrounded by a band 13 to form a sub-batch 101, before being coated to form a batch 100.
- the at least one strip 2 is closed by overlapping its opposite ends 16 and 17.
- the adhesion between the two opposite ends 16 and 17 is achieved by means of a weld activated by ultrasound. It can also be made by gluing, by thermal activation (thermo sealing), staples, by or by any other means.
- the position of the strip 2 of paper, at the level of a flat portion 5 of the containers 1 improves the mechanical strength of the joint of the strip 2 of paper, which is less stressed by friction caused by a movement containers 1 within batch 100.
- the join of the two opposite ends of the strip 2 of paper has strength characteristics at least equivalent to those of the strip 2 of paper.

- the outer face of strip 2 of paper is the visible face of said strip 2 when it coats lot 100.
- Coating 9 can cover both sides of at least one strip 2, or only one of its sides.
- the strip 2 of paper has a coating 9 on its face interior, that is to say the face which is in contact with the flat portion 5 of the containers 1.
- This coating 9 can therefore cover the entirety of one of the two faces, or be produced discontinuously, or even cover partially the length of the strip, for example only at one of the ends 16 or 17.
- This coating 9 can be a purely aesthetic coating, of the varnish or lacquer type for example, to improve the visual rendering of the product, or even for technical purposes, for example to facilitate the printing of information, messages, drawings, signs, etc.
- this coating 9 is a coating for technical purposes, in particular a heat-sealing coating in order to promote the adhesion of the two opposite ends 16 and 17 of the at least one strip 2 of paper.
- a heat-sealing coating 9 is activated by ultrasound or thermally.
- This embodiment advantageously makes it possible to activate the sealing properties in a localized manner.
- the coating 9 before activation, the coating 9 is inactive, that is to say unable to play an adhesive role, and after activation, it takes on adhesive properties.
- the heat-sealing coating 9 covers the entire inner face of the strip 2 of paper, and is activated locally, for example by ultrasound, to form one or more adhesive zones.

- the strip(s) 2 and the band(s) 13 may have a different coating 9, or even no coating 9.
- the coating 9 may be lacquer, paint, or even be a surface treatment for technical purposes , such as a heat-sealing treatment, which can be activated with water, or for aesthetic purposes.
- the batch 100 comprises an additional adhesion means 10 at the level of the contact zone 6, between the flat portion 5 and the strip 2.
- the additional means 10 can be placed initially either on the peripheral wall 7, at the flat portion 5, either on the inner face of the corresponding strip 2, or both.
- said additional adhesion means 10 can be placed either on the peripheral wall 7 of the container 1, at the level of the flat portion 5, or on the inside face of the strip 2 of paper, or both.

- Said additional adhesion means 10 can also, cumulatively or alternatively, be present on the outer face of the strip or strips 13 of paper, in order to improve the bond between the at least one strip 2 of paper and the strip or strips 13 of paper. This embodiment has the advantage of improving the cohesion of the lot 100.
- this additional adhesion means 10 relates to the adhesion between the band 2 or the strip 13 and one or more containers 1, and not the adhesion between two containers 1.
- the additional adhesion means 10 is located at the interface between at least one strip 2 of paper and the at least one strip 13 of paper and/or at the interface between the at least one strip 2 of paper and the peripheral wall 7 of one or more containers 1.
- the batch 100 comprises a handle 11 in the form of at least one strap 12.
- the strap 12 makes it possible to grasp and lift the batch 100 from above said batch, in a normal orientation.
- This strap 12 can be fixed by partial covering of at least one strip 2 of paper.
- each end of the strap 12 can be sandwiched between a strip 13 of paper from a sub-batch 101 and a strip 2 of paper from batch 100.
- the strap 12 is fixed both by partial covering of at least one strip 2 of paper and on a portion of the peripheral wall of two containers 1.
- the strap 12 extends to the -beyond the at least one strip 2 and is attached to the portion of the peripheral wall 7 of the container 1 located below said strip 2, in the direction of the main direction 15.
- the strap 12 can also be fixed on the portion of the peripheral wall 7 located above said strip 2, in the direction of the main direction 15.

- the strap 12 will contribute to maintaining the position of the band 2.
- the strap 12 is fixed, by means of a double-sided adhesive tape or by glue dots, on a part of the peripheral wall 7, in addition to its fixing on the at least one strip 2 of paper.
- This embodiment is particularly advantageous when the batch 100 does not include sub-batches 101.

- the strip 2 of paper then preferably covers at least partially or even totally the height of said label. 14 when said strip coats said containers 1 to form batch 100.
- the invention also relates to a paper holding strip 2 for a batch 100 as defined above.
- the holding strip 2 is made of a paper material, based on vegetable fibers.
- the strip 2 of paper contains a limited quantity of polymers, namely a quantity of less than 30%, preferably less than 10%, of the total mass.
- the composition of the retaining band 2 allows it to meet the criteria of standard EN13430 in terms of recyclability.
- This holding strip 2 in certain embodiments, is made of a paper having a weight of between 50 and 150 g/m2 (gram per square meter), preferably between 90 and 120 g/m2.

- a force of between 0.2 and 5kN/m preferably between 0.2 and 1kN/m
- the force applied is between 10 and 50N. This applied force contributes to the holding together of the containers 1 in the form of a compact batch 100.
- This embodiment is particularly advantageous in the case where the containers 1 are semi-rigid.
- the invention also relates to a method for packaging the aforementioned batch 100, in which at least two containers 1 are grouped together.
- this method is characterized in that it comprises at least the following steps
- the batch is coated with at least one strip 2 at the level of the at least one flat portion 5 of each of said containers 1,
- said at least one strip 2 is affixed with sufficient tension to hold said at least two containers 1 in batch 100.
- the containers 1 can be grouped together in one or more sub-batches 101.
- At least two containers 1 are grouped into at least one sub-batch 101; each sub-batch 101 is surrounded by a band 13 of paper; the sub-batch or batches 101 are coated in batch 100.
- At least one container 1 is not part of a sub-batch 101.
- certain containers 1 can be grouped together in a sub-batch 101, then surrounded by at least one strip paper, while other containers 1 remain free before being coated, with the sub-batch(s) 101, by means of at least one strip 2 of paper, to form a batch 100.
- the sub-batches 101 before coating the batch 100, can be composed according to a transverse and/or longitudinal orientation with respect to the largest dimension of the matrix formed by the batch 100 in order to optimize the strength of batch 100.
- a sub-batch batch 101 is composed of at most four containers 1, preferably two containers 1. It is also possible to have multiple configurations, with an arrangement of sub-batches 101 distributed transversely and longitudinally with respect to batch 100.
- an adhesion means 10 located at the contact zone 6 of each container 1 of a sub-batch 101;
- - can be applied to the outer face of at least one strip 13 of paper, an additional adhesion means 10 located at the level of adjoining zones between two sub-batches, or between a sub-batch 101 and one or more containers 1; and or
- an adhesion means 10 can be applied to the inside face of the at least one strip 2.
- the packaging method comprises a step of fixing a handle 11 in the form of at least one strap 12.
- said strap 12 is fixed by its opposite ends on the inside face of the band 2 of paper, by partial covering, before coating. It can also be fixed after coating batch 100, on the outer face of strip 2 of paper.
- the step of fixing a handle 11 in the form of at least one strap 12 is carried out by fixing both by covering the at least one holding band 2, on its external face, but also by fixing said strap 12 on a portion of the peripheral wall 7 of the containers 1.
- said strap 12 is fixed by glue dots below the at least one strip 2, in the main direction 15.
- the strap 12 covers the at least one band 2 on either side of the batch 100, and each of its ends is fixed on a portion of the peripheral wall 7 of a container 1, located below said at least one strip 2, in the main direction 15.
- the strap 12 can cover each of said strips 2 or only one of said strips 2 .
- a handle 11 in the case where the lot 100 comprises one or more sub-lots 101, after wrapping, a handle 11 can be fixed in the form of at least one strap 12 partially overlapping at least one band 13 of one of the sub-batches 101. Then, when said sub-batch 101 is coated, said strap 12 can be covered, at the level of the adjoining portion with the at least one band 13, with the band 2 forming lot 100. This sandwich fastening of the strap 12 between a headband 13 and a band 2 improves the resistance and the maintenance at this level of the handle 11.
- the batch 100 of containers thus packaged has increased resistance and limits the risks of dismantling of the batch 100 or of unbundling of the containers 1.
- the containers 1, maintained in sub-batches 101 have on the one hand a larger contact surface with the strip 13 of paper which connects the containers 1 together in the same sub-batch 101 and, on the other hand, a larger adjoining zone between the sub-lots 101 of the same lot 100 surrounded by the strip 2 of paper.
- the doubling of the coating increases the resistance of the batch 100 formed, with regard to this material having a certain fragility, which usually excludes its use for containers 1, especially of rounded section and/or made of plastic material.
- this makes it possible to ensure that the containers 1 are kept together, regardless of their position within said batch 100.
- FIG. 1 In a first embodiment, as shown in Figure 1, four containers 1, of rectangular or substantially rectangular section are grouped.
- the containers 1 are held together by the strip 2 of paper, forming a batch 100.
- the strip 2 of paper therefore encircles the containers 1 so as to form mechanical cohesion and a compact batch 100: in the context of its handling, if the batch 100 is moved by gripping only one of the containers 1, all the containers 1 remain attached and are also moved, lifted, namely lifted inseparably from each other within the same batch.
- the strip 2 of paper surrounds the containers 1, grouped in the form of a matrix.
- Said band 2 is affixed around the containers grouped at the flat portion 5 in a direction perpendicular or substantially perpendicular to the main direction 15, namely orthogonally to the height of the containers 1.
- the strip 2 of paper coats the assembly formed by the containers 1 by resting on a flat portion 5 of the body 3 of each of the containers 1 forming the batch 100.
- the container 1 has a height of 400mm (millimeters), and comprises a section with a height of 120mm. On this section, the difference between the diameter at the level of the lower limit 18 and the diameter at the level of the upper limit 19 is 3 mm. Thus, this section can be considered as a flat portion 5. In addition, said section, in this example, does not include grooves 8 or other pattern.
- the strip 2 of paper has a height of 100mm and coats the containers 1, coming to rest at the level of this flat portion 5, to form the batch 100.
- a front view of such a container 1 is represented schematically on the figure 2.
- the containers 1, of generally circular section are grouped in staggered rows, as shown in FIG. 5, in a simplified top view.
- the strip 2 of paper surrounds the containers 1 at the level of a flat portion 5, which is located towards the bottom of the container 1, in the direction of the main direction 15.
- the strip 2 has a coating 9 of type varnish on its outer face.
- the container 1 is illustrated in a front view in FIG. 4. This embodiment, shown in FIG. 3, is particularly advantageous when the containers are small. This embodiment also contributes to the grouped maintenance containers 1 which, when lifting the lot 100, may tend to move apart at their bottom, and then increase the pressure exerted on the band 2 for maintenance.
- the staggered distribution of the containers 1 has various advantages.
- this distribution makes it possible to reduce the friction between the peripheral wall 7 of the containers 1 within the batch 100, during the handling of the latter, and also makes it possible to have a slightly reduced size.
- the strip 2 of paper can be affixed to one or the other of the flat portions 5 of the containers 1. Nevertheless, as illustrated in Figure 6, preferably, the strip 2 of paper will coat the containers 1 at the flat portion 5 located closest to the center of gravity 28 of said containers 1.
- Figure 6 shows a lot 100 , formed by four containers 1. The strip 2 of paper surrounds said containers 1 at the level of the flat portion 5 located towards the bottom of a container 1, in order to improve the overall stability of the batch 100.
- Figure 7 shows the center of gravity 28 of such a container 1 . It is understood that this criterion for choosing the flat portion is all the more important as the containers 1 are high, or contain a large volume. Indeed, the solidity of lot 100 will be all the more tested during transport or handling of the latter.
- the strip 2 of paper does not cover the entire surface of the flat portion 5.
- the strip 2 of paper can be affixed, from and above above the lower limit 18, from and below the upper limit 19, or at a respective distance from one and the other.
- the strip 2 of paper is affixed as close as possible to the center of gravity 28 of the containers 1, since the latter is located between the two aforementioned limits, that is to say in the zone of the flat portion 5.
- Figure 8 shows a front view of a particular container 1.
- the container 1 has a flat portion 5 which takes the form of a right cylinder, the central axis of which is aligned with the central axis of said container 1.
- the flat portion 5, in this illustrative example, is arranged in a groove 29 of the body 3 of the container 1.
- the strip 2 of paper has a height equal to or less than the height of said flat portion 5, which allows it to come to rest against the latter.
- This form of container 1, having a groove of sufficient relative height allows a particularly advantageous positioning of the strip 2 of paper: the groove makes it possible to further improve the holding in position of the strip 2 of paper. Indeed, in this configuration, the strip 2 of paper cannot slip or be moved during the handling or transport of said batch 100.
- the batch 100 comprises two strips 20 and 21 of paper.
- the cumulative height of the two bands 20 and 21 does not exceed one third of the height of the containers 1.
- Such an embodiment may in particular be favored for the packaging of containers 1 of great height, greater than 400mm, or of substantial weight, for example greater than to nine kilograms.
- batch 100 may comprise additional adhesion means 10.
- batch 100 comprises six containers 1 distributed in a rectangular matrix, in three columns and two rows.
- the strip 2 of paper forms the compact batch 100 by surrounding all the containers 1, at the level of their peripheral wall 7.
- Additional adhesion means 10, here glue dots, are present on said peripheral wall 7 of the containers 1, and more particularly at the level of the flat portion 5, which receives said strip 2 of paper during the coating of the batch 100. These dots of glue 10 have the advantage of improving the mechanical strength of the strip 2 of paper.
- This embodiment is particularly desirable when the batch 100 comprises more than four containers 1. Indeed, in such a configuration, the containers 1 located in the middle of the matrix, that is to say the containers 1 of the second column , are surrounded by the strip 2 of paper on a smaller portion compared to the containers 1 located in the corners of the matrix, in the first or third column.
- the contact zone 6 is therefore greater for a container 1 located in a corner of lot 100 than for a container 1 located in the center of said lot 100, as shown in Figure 10.
- the container 1 is semi-rigid, has grooves 8 and a slightly flared shape at the flat portion 5.
- the body 3 of the container 1 flares out, that is to say that the perimeter of the body 3 from the upper limit 19 to the lower limit 18 increases by 6mm.
- the grooves 8 cover approximately 25% of the surface of said flat portion 5.
- the batch 100 is formed by the coating of the containers 1 grouped in staggered rows by means of a strip 2 of paper, affixed at the level of the flat portion 5.
- the contact surface 6, between the wall peripheral 7 of the containers 1 and the strip 2 of paper is sufficient because is 75%: in other words, at the flat portion 5, the strip 2 of paper is in contact with 75% of the peripheral wall 7, the grooves 8 occupying the other 25% are not in contact with the strip 2.
- the joining of the strip 2 of paper is then sufficient to keep the batch 100 compact.
- the strip 2 is made of paper material, and not of self-adhesive plastic material. Thus, it is likely to undergo friction, movement, and move during the handling or transport of lot 100.
- the mechanical strength of the strip 2 of paper is only ensured on the one hand by the choice of its positioning and on the other hand by the tension applied by said strip 2 of paper around lot 100. Once affixed, the strip 2 of paper is in a state of tension such that it applies a force of between 0.2 and 5kN/m against the peripheral wall 7.
- the contact surface 6 between the strip 2 of paper and the peripheral wall 7 must be sufficient, and in particular at least equal to 50% of the surface of the flat portion 5, preferably 70%, at the level of the joining area.
- the height of the retaining strip 2 is appropriate in order to evenly distribute the tension applied to the body of the containers 1. This makes it possible to avoid excessive deformation of the body 3 of the containers 1, in particular in an embodiment where the containers 1 are PET.
- the strip 2 of paper is for example of a height representing a quarter of the height of the containers 1.
- An example of a suitable height is between 40 and 120mm.
- the strip 2 of paper is then capable of absorbing both the shocks associated with transport and the intrinsic deformation of the container 1, due to its content.
- the latter undergo deformations at the level of their body 3: once the container is filled, then closed, it is said to be “finished”.
- said container will undergo slight variations in volume, generally between 0.1 and 4%, increasing or decreasing.
- the volume of the containers 1 can thus increase or decrease depending on the content, for example depending on whether the content is a carbonated drink or not.
- These variations can also be linked to storage conditions, to a rise in temperature for example.
- the volume of a container 1 can vary between the coating operation of a batch 100 of several grouped containers 1, and its final destination, that is to say its consumption or its use.
- the variation in the volume of a container 1 will therefore be influenced by various factors.
- the degassing of the contents of a container 1 during its storage will cause a variation in the volume of said container, and therefore in its diameter.
- the coating of the grouped containers 1 must therefore be solid and reliable: it must make it possible to guarantee the transport, the handling of the batches 100 whatever the intrinsic properties of the container 1, the external conditions and whatever the content of said containers 1.
- the strip 2 of paper must therefore be capable of absorbing these variations in volume of the body 3 of the containers 1 while keeping the batch 100 compact.
- Strip 2 of paper must not tear under the effect of the variation or on the contrary to relax too much, which would lead to a dismantling of the batch 100.
- the optimal positioning of the strip 2 of paper, which coats the containers 1 grouped at the level of a flat portion 5 , in order to constitute a compact and solid batch 100, contributes to avoid these problems.
- FIG. 12 illustrates an embodiment in which the batch 100 comprises a sub-batch 101.
- the batch 100 comprises a sub-batch 101.
- six containers 1 are grouped together in a rectangular matrix, in the form of three columns and two rows.
- a sub-batch 101 of four containers 1 is formed by the last two columns of two products each, by surrounding said four containers 1 with a band 13 of paper.
- Batch 100 is formed by the coating with a strip 2 of paper of sub-batch 101 and the two remaining containers 1.
- additional adhesion means 10 are present on the strip 13 of paper in order to improve its cohesion with the strip 2 of paper.
- additional adhesion means 10 are provided between the remaining containers 1 and the strip 2 of paper.
- the batch 100 of six containers 1 comprises two sub-batches 101 of two containers 1, said sub-batches 101 grouping two containers 1 located diagonally, that is to say on two different rows and two different columns.
- the sub-lots 101 are then arranged at an angle to the rectangular matrix formed by the six containers 1.
- At least one pair of sub-batches 101 and 102 positioned side by side are oriented longitudinally along two rows, while at least one additional sub-batch 103 is positioned longitudinally at least on one side of said pair and oriented transversely, thus forming a column.
- two sub-lots 101 and 102 forming a pair of containers 1 are aligned along the length of the lot 100 and at least one additional sub-lot 103 is positioned transversely at one and/or the other end of a sub-lot 101 or 102.
- the batch 100 can have different configurations, according to which all the containers 1 of the same batch 100 are previously grouped into different sub-batches 101, according to which only part of the total number of containers 1 of the same batch 100 is previously grouped into at least one sub-batch 101 or according to which all the containers 1 of the same batch 100 are directly grouped to form said batch 100.
- Figure 13 shows a perspective view of a batch 100 comprising three sub-batches 101, 102 and 103 being coated.
- the strip 13 of paper from each of the sub-lots 101, 102 and 103 surrounds the containers 1 grouped at the flat portion 5.
- the strip 2 of paper will coat the sub-batches 101 to form the batch 100, coming to rest against the peripheral wall 7, at the level of the same flat portion 5.
- the strip 2 of paper covers the bands 13 of paper.
- the strip 2 of paper has a height greater than the height of the strip 13.
- the strip 2 of paper and the strips 13 of paper have a similar thickness, for example approximately 90 g/m2, and are made in the same paper material.
- the strip 2 of paper has a coating 9 on its inner face, at the level of its end 16, said coating being a heat-sealable coating, which can be activated by means of ultrasound.
- additional adhesion means 10 are positioned between the various sub-batches 101, 102 and 103, on the outer face of each of the strips 13 of paper and between each strip 13 and the strip 2.
- the additional adhesion means 10 are positioned at places where the contact zone 6 between a strip 13 and the containers 1 or between the strip 2 and the containers 1 is the weakest.
- This illustrative example is further shown in Figure 14, where lot 100, as shown in Figure 13, is seen from above.
- the cohesion of the batch 100 is then improved thanks to the double coating: each container 1 is maintained on a sufficient contact zone 6, either by the strip 2 of paper and/or by the strip 13 of paper.
- the additional adhesion means 10 can be applied both to the outer face of the at least one strip 13 of paper and to the inner face of the strip 2 of paper, when the latter completely covers the at least less a strip 13 of paper, to form a double-sided adhesive tape.
- each of the containers 1 has a label 14.
- the label 14 is affixed to the body 3 at the level of a flat portion 5. Nevertheless, the label 14 has a height less than the height of said flat portion 5.
- the strip 2 of paper which here completely covers the label 14, will have greater mechanical strength. Moreover, during the removal of the band 2, that is to say during the voluntary dismantling of the batch 100, the integrity of the label 14 will be preserved. In addition, this mode The embodiment advantageously makes it possible to protect said labels during transport or storage of the batches 100, or even the printing of information specific to the batch 100, of the advertising or commercial type, or else for example a bar code.
- the strip 2 of paper can then have a coating 9 on its outer face, for aesthetic and/or informative purposes.
- this coating 9 when it is for technical purposes, can comprise a specific component.
- the properties of this component can be activated in different ways, for example by heat through a heating, heat-sealing or heat-bonding operation, or can be activated with water, for example by humidification, in particular spraying, or even wetting by contact with a damp surface, or by any other means.
- the coating 9 may be an adhesive or a sticky coating applied to one and/or the other of the faces of the strip 2 of paper and/or to the strip 13 of paper.
- the coating 9 is only applied to the opposite ends 16 and 17 of the strip 2 of paper, and is activated by ultrasound during the coating of the batch 100.
- Figure 17 shows another embodiment, similar to the embodiment shown in Figure 9.
- the strip 13 of paper surrounds each sub-batch 101 and 102 at the level of a flat portion 5.
- Two strips 20 and 21 of paper then form the lot 100: a first strip 20 of paper will be affixed to the band 13 of paper while a second strip 21 of paper will be affixed against the peripheral wall 7 of the containers 1, at another flat portion 5.
- the height of the strip 13 is equivalent to the height of the strip 20 of paper.
- This embodiment is particularly advantageous for containers 1 of great height or of a large volume, in order to further improve the cohesion of the batch 100.
- the invention also relates to a strip 2 of paper to form a batch 100 as described previously.
- the strip 2 is of a minimum height corresponding to one eighth of the height of the containers 1 forming the batch 100.
- the height of the strip 2 corresponds to a quarter of the height of the said containers 1.
- the basis weight of the paper constituting the strip is between 50 and 150 grams per square meter (g/m2), preferably between 90 and 120 g/m2, and even more preferably around 90 g/m2.
- the strip 2 of paper in order for the strip 2 of paper to be able to keep the batch 100 compact, it must first of all be able to conform and be affixed against the peripheral wall 7 of the containers 1. In a case where said strip 2 would be too thick, for example in order to improve its solidity, it would become difficult or even impossible to guarantee an adequate contact zone 6 between said strip 2 of paper and the flat portion 5.
- the strip 2 would not be flexible enough to be able to be attached to the peripheral wall 7 of the containers 1, which could cause it to slide along the body 3 of said containers 1 without being able to hold them together.
- the strip 2 of paper must also be strong enough not to tear from the first handling of the batch 100, or during its storage, for example under the effect of the variation in volume of said containers 1 forming said batch, or even of the mechanical tension necessary to hold together the containers 1 in lot 100.
- the strip 2 of paper has properties of increased resistance compared to a strip made of conventional paper, for a similar thickness, and in particular properties of elongation at break greater than 4% and resistance to traction greater than or equal to 5kN/m (kilonewtons per meter). These properties can be measured perpendicularly and/or parallel to the main direction 15 and these parameters are measured in accordance with the ISO 187 standard and the ISO 1924 standard.
- the strip 2 of paper must therefore be sufficiently flexible and resistant, while avoiding the use of plastic in its composition. This is obtained in particular thanks to properties of elongation at break of between 4 and 11%, for a basis weight of the strip 2 of paper of between 50 and 150 g/m2 (grams per square meter).
- the invention finally relates to a method for packaging a batch 100 of containers 1 as described above.
- Such a packaging method is executed within a packaging line 23, an example of architecture of which is shown in FIG. 18.
- the grouping step consists in distributing a defined number of receptacles 1, namely at least two receptacles 1, for example from a single-wire stream as seen in FIG. 18, or else from a multi-wire stream, or even from an accumulation ordered or in bulk of containers 1, or others.
- the grouped containers 1 will then be assembled and held together to form a batch 100.
- this initial quantity of containers 1 can be supplied by a line located upstream, such as for example a production line for said containers 1.
- Said grouping can be carried out by a grouping station 24 intervening to separate the initial quantity of containers 1 and bring together the number of containers 1 determined to form the batch 100.
- the method comprises a step of coating at least two containers 1 by means of the strip 2 of paper.
- the coating therefore makes it possible to form the batch 100 of containers 1 to hold them together.
- lot 100 no longer circulates: the conveyor belt or the shuttle on which it rests is stopped.
- batch 100 is coated as it travels, at reduced speed.
- the batch 100 remains stationary while the strip feed performs the coating by rotating around said batch 100.
- the batch 100 performs clockwise and/or anti-clockwise rotations by with respect to the feeding of the strip 2 of paper.
- the containers 1 are optionally combined into at least one sub-batch 101, each sub-batch 101 grouping together at least two containers 1.
- the grouping step then makes it possible to gather the corresponding number of containers 1 from each sub-batch 101, namely at least by two containers 1, as shown in Figure 18.
- each sub-batch 101 is surrounded by unrolling at least one strip 13 of paper, which will be affixed to the peripheral wall 7 of the containers 1, at the level of a flat portion 5.
- a strip 13 is unrolled at least until its ends are covered.
- several strips 13 of paper can be unrolled on either side of the containers 1 of each sub-batch 101, until they are connected together.
- Such an entourage is performed by a station 25 of entourage of the line 23 of conditioning.
- the sub-lot(s) 101 are stationary or travel at reduced speed.
- the sub-lots 101 can be stationary or perform clockwise and/or anti-clockwise rotations relative to the supply of the strip 13 of paper.
- the at least one sub-batch 101, and possibly the remaining containers 1 is coated by unrolling said at least one strip 2 of paper until its ends 16 and 17 are covered.
- the at least one strip 2 of paper will come to rest against the peripheral wall 7 of the container 1, at the level of a flat portion 5.
- the coating step makes it possible to hold the containers 1 of a batch 100, possibly once a part of these containers 1 has previously been surrounded to form one or more sub-batches 101.
- Such coating is carried out by a coating station 26 of the line 23 of packaging.
- Figure 18 shows a step of positioning the sub-batches 101 transversely side by side at the entrance to the station 26 of coating.
- the corresponding items 25 and 26 can be configured to indicate what force must be applied by the strip 13 of paper and/or or by strip 2 of paper.
- the force applied by the strip 13 of paper and/or strip 2 of paper must be between 0.2 and 5 kN/m (kilonewtons per meter), preferably 0.2 to lkN/m at the flat portion 5.
- the force applied is between 10 and 50N. This applied force helps hold the containers 1 together as a compact pack 100.
- each sub-batch 101 is surrounded by a separate station 25: there are therefore several stations 25 on the same packaging line 23.
- packaging line 23 includes two coating stations 26.
- the same station 25 carries out the entourage of at least one sub-batch 101 then the coating of the batch 100.
- This embodiment is particularly advantageous because it makes it possible to increase the rate of the packaging line 23. This also has an ecological impact because it makes it possible to reduce the energy consumption of said line.
- the method comprises an additional step.
- a handle 11 is fixed in the form of at least one strap 12 partially overlapping at least one band 13 of paper from one of the sub-batches 101. Then, at the time of coating, said strap 12 is covered with strip 2 of paper.
- Such fixing of the handle 11 is performed by a station 27 for fixing the line 23 of packaging.
- a fixing station 27 can intervene between the surrounding station 25 and the encapsulating station 26, directly along the stream of sub-batches 101, or else by taking a sub-batch 101 from said stream and then reinserting it before coating in the flow of sub-batches 101, at a determined position, for example in the center of the batch 100 to be formed, as seen in the example of Figure 16.
- the method may include an additional step: before coating a batch 100, an additional adhesion means 10 is applied to the inside face of each strip 2 of paper, located at the level of the contact zone 6 of each container 1 of the batch 100.
- an additional adhesion means 10 is applied to the outer face of a strip 13 of a sub-batch 101, at the level of adjoining zones between two sub-batches 101, or between a sub-batch 101 and one or more other containers 1.
- the invention makes it possible to obtain excellent hold and a solid hold of at least two containers 1 grouped together, by means of a band 2 of paper, affixed to a flat portion of said containers, which guarantees packaging that respects the environment.
- the strip 2 of paper is made of paper having a weight of between 50 and 150 g/m2 (gram per square meter). This allows both to use little of raw materials for the production of strip 2, and to generate little waste. In addition, such a weight allows the strip 2 to adapt to the general shape of the containers 1. In particular, the strip 2 will be able to bend, to conform to the outer contour of the batch 100. Too great a thickness of the strip 2 would lead to a lack of flexibility of the latter, which could then not match the shape of the containers 1 forming the batch 100. However, so that the batch 100 does not break up, it is necessary to have an adequate contact zone between the strip 2 of paper and each of the containers 1 of said batch 100. Such a weight makes it possible to combine good shape retention as well as good mechanical strength of the strip 2 itself.
- the containers 1 rest on their bottom in a normal orientation. In other words, the containers 1 which form the batch 100 are in a vertical position. This allows a user to have a classic and adapted use.
- the paper strip 2 has a height of at least fifty percent of the height H of each of the containers 1 along the main direction 15.
- the invention by affixing a strip 2 of paper against the flat portion of a container 1, makes it possible both to guarantee great solidity of the batch, but also to considerably reduce the volume of waste.
- the invention also relates to an installation 100 for packaging containers 1 in batches implementing the method of the invention, said installation thus producing batches 100 as described here in the different possible variants.
- the packaging installation therefore produces batches 100 of at least two containers 1 according to the invention.
- the batch packaging installation is characterized in that it uses a strip 2 of paper.
- the packaging installation comprises in particular a grouping station 24 of at least two containers 1, at least one coating station 26 of at least one strip 2 of paper around the assembly that they form.
- the installation includes an entourage station 25 for creating sub-lots 101.
- the wrapping station 25 and/or the enrobing station 26 comprises a sealing module for closing said strip 2 around the lot 100 by linking its opposite ends 16 and 17 to close it on itself.
- This sealing module can be an adhesive activation module by water, or else by heat.
- the sealing module is an ultrasonic welding module.
- the tape sealing module is a separate module from stations 25 and 26.
- the installation comprises at least one fixing station 27 of a strap 12 in the form of a handle 11 around the lot 100.
- the fixing station 27 is located downstream of the module for affixing the strip 2 of paper.
- the surrounding station 25 and the encapsulating station 26 of at least one strip 2 of paper form a single and same station.
- the station 26 for encapsulating at least one strip 2 of paper and the fixing station 27 form one and the same station.
- the enrobing station 26 is capable of depositing a strap 12 in the form of a handle 11 around the lot 100.

Description
LOT COMPACT DE RECIPIENTS GROUPES, PROCEDE DE COMPACT BATCH OF GROUPED CONTAINERS, METHOD FOR
CONDITIONNEMENT ET INSTALLATION PACKAGING AND INSTALLATION
La présente invention relève du domaine du conditionnement de récipients en lot. Elle a pour objet un lot compact de récipients groupés, une bande de maintien destinée à former ledit lot et un procédé mettant en oeuvre ce lot. The present invention relates to the field of the packaging of containers in batches. It relates to a compact batch of grouped containers, a retaining strip intended to form said batch and a method implementing this batch.
Dans le cadre de la présente invention, le récipient est une bouteille ou un flacon. Un tel récipient est destiné à contenir, de façon non exhaustive, un fluide, un liquide, des poudres ou des granulés, notamment de type agroalimentaire ou cosmétique. In the context of the present invention, the container is a bottle or a flask. Such a container is intended to contain, in a non-exhaustive manner, a fluid, a liquid, powders or granules, in particular of the food-processing or cosmetic type.
De manière connue, au sein d'une ligne industrielle, les récipients peuvent recevoir plusieurs traitements successifs différents, comme la fabrication du contenant, par exemple lors d'une opération d'injection plastique ou d'étirage-soufflage dans le cas d'une bouteille en matériau plastique, suivi du remplissage puis de la fermeture par un bouchon et l'étiquetage. A l'issue de ces traitements, les récipients sont dits "finis". In known manner, within an industrial line, the containers can receive several different successive treatments, such as the manufacture of the container, for example during a plastic injection or stretch-blow molding operation in the case of a plastic bottle, followed by filling then closing with a cap and labelling. At the end of these treatments, the containers are said to be "finished".
En vue de leur manutention, de tels récipients finis subissent un conditionnement en lot. Ainsi, chaque lot comprend plusieurs récipients, rassemblés par exemple selon une disposition en matrice, généralement de forme globalement parallélépipédique, souvent carrée ou rectangle, selon des colonnes et des rangées. A titre d'illustration, un lot habituel regroupe six récipients selon deux rangées et trois colonnes. With a view to handling them, such finished containers are packaged in batches. Thus, each batch comprises several containers, brought together for example in a matrix arrangement, generally of generally parallelepipedic shape, often square or rectangle, according to columns and rows. By way of illustration, a typical batch groups together six containers in two rows and three columns.
Une fois les groupes de récipients réalisés, chaque groupe est enrobé, en particulier recouvert avec un film, afin de maintenir les récipients ensemble et de faciliter la manutention d'un tel lot ainsi obtenu. Un tel enrobage peut être effectué au travers d'une étape de filmage ou préférentiellement de fardelage. En particulier, le fardelage d'un groupe de récipients consiste à l'enrober au moyen d'une feuille d'un film plastique en matériau thermo-rétractable. Un groupe enrobé subit ensuite une étape de chauffage pour que la feuille vienne épouser la forme globale extérieure des récipients. En somme, la feuille de film se rétracte sous l'effet de la chaleur pour former un rétreint assurant le maintien des récipients groupés. Once the groups of containers have been made, each group is coated, in particular covered with a film, in order to hold the containers together and to facilitate the handling of such a batch thus obtained. Such encapsulation can be carried out through a step of filming or preferably wrapping. In particular, wrapping a group of containers consists of wrapping it with a sheet of plastic film made of heat-shrinkable material. A coated group then undergoes a heating step so that the sheet conforms to the overall external shape of the containers. In short, the sheet of film shrinks under the effect of heat to form a constriction ensuring the maintenance of the grouped containers.
Le regroupement des récipients, l'enrobage et le chauffage sont réalisés au moyen d'une installation dédiée de type fardeleuse, au travers de plusieurs postes successifs. Une telle opération de chauffage représente une dépense énergétique importante. Une telle solution de conditionnement implique non seulement une consommation d'énergie importante d'un point de vue financier, mais est aussi néfaste pour l'environnement. En effet, l'enrobage s'effectue à partir d'un film en matériau plastique, essentiellement obtenu à partir de la filière pétrochimique. Or, près de la moitié des déchets de plastiques retrouvés dans la mer sont des objets en plastique à usage unique. The grouping of the containers, the coating and the heating are carried out by means of a dedicated installation of the bundler type, through several successive stations. Such a heating operation represents a significant energy expenditure. Such a packaging solution not only involves significant energy consumption from a financial point of view, but is also harmful to the environment. Indeed, the coating is carried out from a film of plastic material, essentially obtained from the petrochemical industry. However, almost half of the plastic waste found in the sea is single-use plastic objects.
Actuellement, de nombreux plastiques sont dits « recyclables » mais cette démarche est globalement insuffisante et insatisfaisante. En effet, l'utilisation de films en plastique rétractables a de nombreux impacts négatifs sur l'environnement : dépense énergétique conséquente, usage unique,
taux de recyclage faible, exportation massive des déchets plastiques vers des pays disposant d'infrastructures de recyclage, etc. Par ailleurs la composition du film, seulement partiellement recyclable, va compliquer le processus et les déchets induits ne seront pas valorisés dans la grande majorité des cas. Currently, many plastics are said to be “recyclable” but this approach is generally insufficient and unsatisfactory. Indeed, the use of shrink plastic films has many negative impacts on the environment: significant energy expenditure, single use, low recycling rate, massive export of plastic waste to countries with recycling infrastructure, etc. Furthermore, the composition of the film, which is only partially recyclable, will complicate the process and the resulting waste will not be recovered in the vast majority of cases.
Ainsi, il existe un besoin croissant de trouver une alternative à l'utilisation de ce matériau générant énormément de déchets et coûteux énergétiquement, à la fois en simplifiant les emballages mais aussi en réduisant la quantité totale de matière utilisée. Thus, there is a growing need to find an alternative to the use of this material which generates a lot of waste and is energy costly, both by simplifying the packaging but also by reducing the total quantity of material used.
Dans ce domaine, une alternative connue à l'utilisation d'un film plastique rétractable pour la formation d'un lot consiste à maintenir les produits ensemble au moyen d'un cerclage ou d'une sangle, qui va venir entourer les récipients. In this field, a known alternative to the use of a shrink-wrapped plastic film for the formation of a batch consists in holding the products together by means of strapping or a strap, which will surround the containers.
Par exemple, on connaît le brevet US5570787 qui propose de maintenir groupés ensemble des récipients pour former un lot, notamment en entourant les récipients avec une large bande de plastique élastique. Cette bande recouvre une grande portion de la hauteur des produits. Le lot formé et entouré est maintenu par une sangle élastique latérale, apposée sur le contour extérieur des récipients, mais également par une sangle complémentaire, formant la poignée, qui maintient le lot par le fond des récipients. La poignée et la sangle latérale coopèrent afin de permettre le maintien ensemble des récipients. Cette alternative présente certes l'avantage de réduire sensiblement la quantité totale de plastique utilisé mais reste néfaste pour l'environnement, les deux sangles entourant le lot étant toutes deux en matière plastique élastique. For example, patent US5570787 is known, which proposes keeping containers grouped together to form a batch, in particular by surrounding the containers with a wide band of elastic plastic. This band covers a large portion of the height of the products. The batch formed and surrounded is held by a lateral elastic strap, affixed to the outer contour of the containers, but also by a complementary strap, forming the handle, which holds the batch by the bottom of the containers. The handle and the side strap cooperate to allow the containers to be held together. This alternative certainly has the advantage of substantially reducing the total amount of plastic used but remains harmful to the environment, the two straps surrounding the lot being both made of elastic plastic material.
DE102011107265 propose quant à lui de relier les récipients entre eux au moyen de points de colle et de finaliser le maintien à l'aide d'une bande adhésive ou autocollante venant cercler le lot. La bande autocollante est de préférence transparente, placée au niveau de l'étiquette des produits, pour permettre au consommateur de visualiser les informations présentes sur l'étiquette. Cette sangle peut être en matériau composite, c'est-à-dire composée de plusieurs matériaux différents. Elle présente donc l'inconvénient d'être peu, voire pas recyclable compte tenu de la difficulté de séparer les matières dites recyclables des autres matières. Par ailleurs, elle présente un autre inconvénient, car lors de son retrait elle risque d'abîmer l'étiquette présente sur le récipient, dans la mesure où elle est autocollante. DE102011107265 proposes to connect the containers together by means of glue dots and to finalize the maintenance using an adhesive or self-adhesive band coming to encircle the lot. The self-adhesive strip is preferably transparent, placed at the level of the label of the products, to enable the consumer to view the information present on the label. This strap can be made of a composite material, that is to say composed of several different materials. It therefore has the disadvantage of being little or even not recyclable given the difficulty of separating so-called recyclable materials from other materials. Furthermore, it has another drawback, because when it is removed it risks damaging the label present on the container, insofar as it is self-adhesive.
Une coopération entre un ruban de cerclage et une poignée de transport du lot est aussi décrite dans US20110089055. Des moyens complémentaires sont prévus pour maintenir les récipients groupés ensemble et il est décrit un procédé spécifique pour éviter que les récipients ne tournent sur eux-mêmes, ce qui conduirait à une déformation du lot et à une instabilité des récipients. Le ruban de cerclage est fixé au lot en deux points opposés, sur la surface d'un récipient afin de garantir sa position. Cette solution présente les mêmes inconvénients de recours à des matériaux composites. Par ailleurs, le procédé de conditionnement est complexe et nécessite de nombreuses étapes pour garantir le maintien des récipients en lot.
Dans le domaine de l'invention, il est donc nécessaire de mettre au point un dispositif de conditionnement de récipients en lot, respectueux de l'environnement, et qui garantit un maintien optimal du lot, que ce soit lors de son transport ou pendant sa durée de stockage. Cooperation between a strapping tape and a carrying handle of the batch is also described in US20110089055. Complementary means are provided to keep the containers grouped together and a specific method is described to prevent the containers from turning on themselves, which would lead to a deformation of the batch and to an instability of the containers. Strapping tape is attached to the batch at two opposite points on the surface of a container to secure its position. This solution has the same disadvantages of using composite materials. Furthermore, the packaging process is complex and requires many steps to ensure that the containers are kept in a batch. In the field of the invention, it is therefore necessary to develop a device for packaging containers in batches, respectful of the environment, and which guarantees optimal maintenance of the batch, whether during its transport or during its storage duration.
L'invention vise ainsi à fournir un dispositif de maintien à la fois fiable, solide et écologique, tant dans sa composition que dans la quantité de déchets générée. Ainsi, l'impact environnemental de l'invention est largement diminué par rapport à un conditionnement utilisant du matériau plastique. The invention thus aims to provide a holding device that is reliable, solid and ecological, both in its composition and in the quantity of waste generated. Thus, the environmental impact of the invention is greatly reduced compared to packaging using plastic material.
Pour ce faire, l'invention propose une solution consistant à maintenir les récipients solidaires entre eux, sous forme de lot, avec au moins une bande de papier apposée au niveau d'une portion plane de chacun des récipients. Ce positionnement de la bande garantit la solidité du lot : la bande ne glisse pas et exerce une pression adéquate au niveau de la paroi des récipients. To do this, the invention proposes a solution consisting in holding the containers integral with each other, in the form of a batch, with at least one strip of paper affixed at the level of a flat portion of each of the containers. This positioning of the band guarantees the solidity of the batch: the band does not slip and exerts adequate pressure on the wall of the containers.
L'invention a ainsi pour objet un lot qui comprend au moins deux récipients, et au moins une bande fermée qui les maintient groupés ensemble, lesdits récipients étant éventuellement munis d'une étiquette, lesdits récipients ayant chacun un corps et un fond, alignés dans une direction principale, le corps présentant au moins une portion plane. The subject of the invention is thus a batch which comprises at least two containers, and at least one closed band which keeps them grouped together, said containers possibly being provided with a label, said containers each having a body and a bottom, aligned in a main direction, the body having at least one planar portion.
Le lot se caractérise en ce que ladite au moins une bande est en papier, a une hauteur inférieure ou égale à la hauteur de ladite portion plane et est apposée autour du lot au niveau de ladite au moins une portion plane de chacun desdits récipients, de sorte à former une zone de contact entre ladite portion plane et ladite au moins une bande de papier. The lot is characterized in that said at least one strip is made of paper, has a height less than or equal to the height of said flat portion and is affixed around the lot at the level of said at least one flat portion of each of said containers, so as to form a contact zone between said flat portion and said at least one strip of paper.
L'invention a aussi pour objet une bande de maintien en papier pour un lot tel que défini ci- dessus. The invention also relates to a paper holding strip for a batch as defined above.

L'invention a ainsi tout d'abord pour objet un lot 100 qui comprend au moins deux récipients 1, et au moins une bande 2 fermée qui les maintient groupés ensemble, lesdits récipients 1 étant éventuellement munis d'une étiquette 14, lesdits récipients 1 ayant chacun un corps 3 et un fond 4, alignés dans une direction principale 15, le corps 3 présentant au moins une portion plane 5. The invention thus firstly relates to a batch 100 which comprises at least two containers 1, and at least one closed strip 2 which keeps them grouped together, said containers 1 possibly being provided with a label 14, said containers 1 each having a body 3 and a bottom 4, aligned in a main direction 15, the body 3 having at least one flat portion 5.
Dans le cadre de l'invention, le récipient 1 est une bouteille ou un flacon. Il peut être réalisé en tout matériau, notamment en matière plastique ou encore en verre. De préférence, le récipient est en poly téréphtalate d'éthylène, ci-après PET. Le récipient 1 peut donc être rigide ou semi-rigide. Il est destiné à contenir un fluide, un liquide, des poudres ou des granulés, notamment de type agroalimentaire ou cosmétique. Le récipient 1 peut présenter tout type de forme, symétrique ou non. Il peut avoir une section arrondie, globalement de forme circulaire ou ovoïdale, ou bien de section polygonale, notamment rectangle ou carrée. Préférentiellement, lesdits récipients ont une section arrondie, notamment globalement circulaire. In the context of the invention, the container 1 is a bottle or a flask. It can be made of any material, in particular plastic or even glass. Preferably, the container is made of polyethylene terephthalate, hereinafter PET. The container 1 can therefore be rigid or semi-rigid. It is intended to contain a fluid, a liquid, powders or granules, in particular of the food-processing or cosmetic type. The container 1 can have any type of shape, symmetrical or not. It may have a rounded section, generally of circular or ovoidal shape, or else of polygonal section, in particular rectangle or square. Preferably, said containers have a rounded section, in particular generally circular.
De manière connue, au sein d'une ligne industrielle, les récipients peuvent recevoir plusieurs traitements successifs différents, comme la fabrication du contenant, par exemple lors d'une opération d'injection plastique ou d'étirage-soufflage dans le cas d'une bouteille en matériau plastique, suivi du remplissage puis de la fermeture par un bouchon et l'étiquetage. A l'issue de ces traitements, les récipients sont dits "finis". In known manner, within an industrial line, the containers can receive several different successive treatments, such as the manufacture of the container, for example during a plastic injection or stretch-blow molding operation in the case of a plastic bottle, followed by filling then closing with a cap and labelling. At the end of these treatments, the containers are said to be "finished".
Le récipient 1 peut éventuellement présenter une étiquette 14. Ladite étiquette 14 peut être apposée sur le corps 3 du récipient 1, ou être rattachée au niveau du col dudit récipient 1, sous la forme d'un ticket. L'étiquette 14 peut également se présenter sous la forme d'un manchon rétractable, qui va épouser la forme dudit récipient 1. L'étiquette 14, lorsqu'elle est présente, a pour fonction de délivrer des informations sur le contenu du récipient 1, ou encore un message publicitaire, un logo, un code barre. The container 1 may optionally have a label 14. Said label 14 may be affixed to the body 3 of the container 1, or be attached at the level of the neck of the said container 1, in the form of a ticket. The label 14 can also be in the form of a retractable sleeve, which will match the shape of said container 1. The label 14, when present, has the function of delivering information on the contents of the container 1 , or even an advertising message, a logo, a bar code.
En vue de leur manutention, de tels récipients finis subissent un conditionnement en lot.
Chaque lot comprend donc plusieurs récipients, rassemblés par exemple selon une disposition en matrice, généralement de forme globalement parallélépipédique, souvent carrée ou rectangle, selon des colonnes et des rangées. With a view to handling them, such finished containers are packaged in batches. Each batch therefore comprises several containers, brought together for example in a matrix arrangement, generally of generally parallelepipedic shape, often square or rectangle, in columns and rows.
Lors de leur conditionnement, les récipients peuvent être également répartis en quinconce. Le lot quinconcé peut présenter différents avantages. L'agencement en quinconce offre notamment plus de points de contact entre les produits regroupés. Par ailleurs, la friction supplémentaire qui s'exerce entre les récipients va accroître la résistance du lot. L'agencement en quinconce permet également d'optimiser l'espace entre les récipients, et représente donc un gain en capacité de stockage. Il est alors possible d'empiler davantage de lots sur une palette. When they are packaged, the containers can also be staggered. The staggered lot can have different advantages. The staggered arrangement notably offers more points of contact between the grouped products. Furthermore, the additional friction between the containers will increase the strength of the batch. The staggered arrangement also makes it possible to optimize the space between the containers, and therefore represents a gain in storage capacity. It is then possible to stack more batches on a pallet.
Comme évoqué précédemment, les récipients 1 présentent un corps 3, et un fond 4. Dans une orientation normale, le récipient 1 repose sur son fond 4. Le fond 4 peut être plat ou de forme pétaloïde. Le corps 3 comprend une paroi périphérique 7. As mentioned above, the containers 1 have a body 3 and a bottom 4. In a normal orientation, the container 1 rests on its bottom 4. The bottom 4 can be flat or petaloid in shape. The body 3 comprises a peripheral wall 7.
Par ailleurs, le terme « compact » correspond à un lot 100 dans lequel des récipients 1 sont rapprochés et positionnés côte à côté, accolés les uns aux autres lors de leur groupage selon une des configurations décrites. Les récipients 1 sont maintenus ensemble par une bande 2 fermée, c'est-à- dire que ladite bande 2 enrobe l'ensemble des récipients, en étant apposée contre une portion de la paroi périphérique 7, pour former un lot 100. Une fois les récipients 1 groupés et enrobés, ils sont alors solidaires entre eux, formant intégralement un lot 100. Les récipients 1 d'un tel lot 100 sont alors indissociables, sauf à démanteler volontairement ledit lot 100 pour en extraire un ou plusieurs récipients 1. Furthermore, the term “compact” corresponds to a batch 100 in which containers 1 are brought together and positioned side by side, joined to each other during their grouping according to one of the configurations described. The containers 1 are held together by a closed strip 2, that is to say that said strip 2 coats all of the containers, being affixed against a portion of the peripheral wall 7, to form a batch 100. Once the containers 1 grouped and coated, they are then integral with each other, integrally forming a batch 100. The containers 1 of such a batch 100 are then inseparable, except to voluntarily dismantle said batch 100 to extract one or more containers 1.
Le récipient 1 présente au moins une portion plane 5. Au niveau de ladite portion 5, la paroi périphérique 7 du corps 3 s'étend sensiblement parallèlement à la direction principale 15. Container 1 has at least one flat portion 5. At said portion 5, peripheral wall 7 of body 3 extends substantially parallel to main direction 15.
La portion plane 5 présente une limite inférieure 18 et une limite supérieure 19. Dans une orientation normale, lorsque le récipient 1 repose sur le fond 4, la limite inférieure 18 de la portion plane 5 est la bordure qui se situe à la plus petite hauteur par rapport à la hauteur totale dudit récipient 1, en partant du fond 4 dudit récipient 1, dans la direction principale 15. La limite supérieure 19 correspond donc à la bordure de ladite portion plane 5 qui se situe à la plus grande hauteur par rapport à la hauteur totale du récipient 1, en partant du fond 4. Autrement dit, la portion plane 5 représente un tronçon de la paroi périphérique 7, du corps 3, s'étendant entre une limite inférieure 18 et une limite supérieure 19. The flat portion 5 has a lower limit 18 and an upper limit 19. In a normal orientation, when the container 1 rests on the bottom 4, the lower limit 18 of the flat portion 5 is the edge which is located at the smallest height. relative to the total height of said container 1, starting from the bottom 4 of said container 1, in the main direction 15. The upper limit 19 therefore corresponds to the edge of said flat portion 5 which is located at the greatest height relative to the total height of the container 1, starting from the bottom 4. In other words, the flat portion 5 represents a section of the peripheral wall 7, of the body 3, extending between a lower limit 18 and an upper limit 19.
De manière classique, le périmètre du récipient 1, ou son diamètre lorsque ledit récipient est de forme circulaire, peut varier le long de sa hauteur. Au niveau de la portion plane 5, le corps 3 a une forme proche de celle d'un cylindre à base de cercle, et notamment suffisamment proche d'un tel cylindre de révolution pour que la bande 2 qui y est apposée exerce une force suffisante pour maintenir les récipients 1 ensemble.
Lorsque le récipient 1 est de section circulaire, la portion plane 5 peut par exemple être située au niveau d'un cylindre droit : le diamètre de la bouteille au niveau de la limite supérieure 19 de la portion plane 5 est égal au diamètre de la bouteille au niveau de la limite inférieure 18 de ladite portion. Si le diamètre varie, dans ce cas, la différence de diamètre entre la limite inférieure 18 et la limite supérieure 19 de la portion plane 5 est tout au plus de 10mm (millimètres) tous les 100mm. De préférence, ladite différence de diamètre est inférieure ou égale à 4mm tous les 100mm. En d'autres termes, le récipient 1 peut par exemple comporter des sections de forme conique, et la portion plane 5 peut se situer au niveau d'une telle section, dans la mesure où la forme conique ne s'évase ou ne rétrécit pas au-delà d'un certain angle, qui correspond à 10mm tous les 100mm, de préférence à 4mm tous les 100mm. Conventionally, the perimeter of container 1, or its diameter when said container is circular in shape, can vary along its height. At the level of the flat portion 5, the body 3 has a shape close to that of a cylinder based on a circle, and in particular sufficiently close to such a cylinder of revolution for the strip 2 which is affixed to it to exert sufficient force. to hold the containers 1 together. When the container 1 has a circular section, the flat portion 5 can for example be located at the level of a right cylinder: the diameter of the bottle at the level of the upper limit 19 of the flat portion 5 is equal to the diameter of the bottle at the lower limit 18 of said portion. If the diameter varies, in this case, the difference in diameter between the lower limit 18 and the upper limit 19 of the flat portion 5 is at most 10mm (millimeters) every 100mm. Preferably, said difference in diameter is less than or equal to 4mm every 100mm. In other words, the container 1 can for example comprise sections of conical shape, and the planar portion 5 can be located at the level of such a section, insofar as the conical shape does not widen or shrink. beyond a certain angle, which corresponds to 10mm every 100mm, preferably 4mm every 100mm.
Lorsque le récipient 1 n'est pas de forme circulaire, par exemple de section globalement rectangulaire, carrée ou polygonale, la différence de périmètre entre la limite inférieure 18 et la limite supérieure 19 de la portion plane 5 est au plus de 10mm tous les 100mm, de préférence égale ou inférieure à 4mm tous les 100mm, afin de garantir la cohésion du lot 100 de manière optimale. When the container 1 is not circular in shape, for example of generally rectangular, square or polygonal section, the difference in perimeter between the lower limit 18 and the upper limit 19 of the flat portion 5 is at most 10mm every 100mm , preferably equal to or less than 4mm every 100mm, in order to guarantee the cohesion of batch 100 in an optimal manner.
De façon générale, la portion plane 5, au niveau de la zone de contact 6, s'étend dans une direction parallèle ou sensiblement à la direction principale 15. Le corps 3 du récipient 1, au niveau de la portion plane 5, a éventuellement la forme d'un cylindre droit. La tension exercée par la bande 2 de papier en formant le lot 100 est alors répartie de façon homogène sur l'ensemble de la portion plane 5. In general, the flat portion 5, at the level of the contact zone 6, extends in a direction parallel or substantially to the main direction 15. The body 3 of the container 1, at the level of the flat portion 5, optionally has the shape of a right cylinder. The tension exerted by the strip 2 of paper forming the batch 100 is then distributed evenly over the whole of the flat portion 5.
Dans certains modes de réalisation, le récipient 1 peut présenter plusieurs portions planes 5.In some embodiments, the container 1 may have several flat portions 5.
Selon l'invention, le lot est caractérisé en ce que la au moins une bande 2 est en papier, a une hauteur inférieure ou égale à la hauteur de ladite portion plane 5 et est apposée autour du lot 100 au niveau de ladite au moins une portion plane 5 de chacun desdits récipients 1, de sorte à former une zone de contact 6. According to the invention, the batch is characterized in that the at least one strip 2 is made of paper, has a height less than or equal to the height of said flat portion 5 and is affixed around the batch 100 at the level of said at least one flat portion 5 of each of said containers 1, so as to form a contact zone 6.
La portion plane 5 comprend donc une zone de contact 6. Cette zone de contact 6 représente la surface de contact entre la au moins une bande 2 de papier et la paroi périphérique 7 du corps 3 au niveau de la portion plane 5. La zone de contact 6 correspond donc à la surface effective contre laquelle la bande 2 de papier est apposée contre la paroi périphérique 7. En d'autres termes, l'interaction entre la bande 2 et la paroi périphérique 7 au niveau de la portion plane 5 forme la zone de contact 6. Ainsi, dans le cas d'un récipient à base circulaire, la zone de contact 6 correspond à un quart de tour pour une bouteille située dans un angle du lot 100. Pour un récipient situé au centre du lot, c'est-à-dire entre les coins dudit lot, la zone de contact 6, formée par l'apposition de la bande 2 sur la paroi périphérique 7, correspond à un contact linéique dans la direction principale 15. The flat portion 5 therefore comprises a contact zone 6. This contact zone 6 represents the contact surface between the at least one strip 2 of paper and the peripheral wall 7 of the body 3 at the level of the flat portion 5. The zone of contact 6 therefore corresponds to the effective surface against which the strip 2 of paper is affixed against the peripheral wall 7. In other words, the interaction between the strip 2 and the peripheral wall 7 at the level of the flat portion 5 forms the contact zone 6. Thus, in the case of a container with a circular base, the contact zone 6 corresponds to a quarter turn for a bottle located in a corner of the lot 100. For a container located in the center of the lot, c that is to say between the corners of said lot, the contact zone 6, formed by the affixing of the strip 2 to the peripheral wall 7, corresponds to a line contact in the main direction 15.
En outre, selon l'invention, la bande 2 est réalisée en papier, c'est-à-dire qu'elle est composée principalement ou majoritairement de fibres de cellulose. A ce titre, le terme « papier » rentre dans le
domaine spécifique du conditionnement de récipients 1 et se limite aux papiers d'emballage. Le terme « papier » exclut le carton, le carton ondulé, et les cartons plats. Furthermore, according to the invention, the strip 2 is made of paper, that is to say it is composed mainly or mainly of cellulose fibers. As such, the term "paper" falls within the specific field of container packaging 1 and is limited to wrapping paper. The term "paper" excludes cardboard, corrugated cardboard, and cartonboard.
En outre, un tel papier est à base de fibres de cellulose. A titre d'exemple, le papier utilisé dans l'invention peut être un papier kraft ou un dérivé du papier kraft. De manière avantageuse, la bande est réalisée dans un papier présentant une résistance accrue, une limite à la rupture appropriée, du fait de son procédé de fabrication. La résistance ou l'extensibilité du papier sont des caractéristiques qui peuvent être améliorées au cours du procédé de fabrication, par exemple par l'ajout d'une trame, ou de fibres spécifiques. Les fibres peuvent également être orientées dans le sens longitudinal ou transversal, pour améliorer la résistance à l'allongement avant rupture selon le sens de l'orientation. In addition, such paper is based on cellulose fibers. By way of example, the paper used in the invention may be kraft paper or a derivative of kraft paper. Advantageously, the band is made of a paper having increased strength, an appropriate breaking limit, due to its manufacturing process. The resistance or the extensibility of the paper are characteristics which can be improved during the manufacturing process, for example by adding a weft, or specific fibers. The fibers can also be oriented in the longitudinal or transverse direction, to improve the resistance to elongation before rupture according to the direction of orientation.
Préférentiellement, la bande 2 de papier est constituée majoritairement de composants biodégradables et/ou recyclables. Preferably, the strip 2 of paper consists mainly of biodegradable and/or recyclable components.
Le positionnement de la au moins une bande 2, réalisée en papier, contribue à la solidité du lot 100. The positioning of at least one strip 2, made of paper, contributes to the solidity of lot 100.
Selon une autre caractéristique additionnelle possible, ladite zone de contact 6, formée par l'apposition de la bande 2 de papier sur la paroi périphérique 7 du récipient 1 au niveau de la portion plane 5, s'étend sur au moins 50% (pourcents) de ladite portion plane 5, de préférence au moins 70%, dans la direction principale 15. En d'autres termes, au niveau du tronçon considéré, formant la portion plane 5 entre la limite inférieure 18 et la limite supérieure 19, la au moins une bande 2 de papier doit être en contact avec la paroi périphérique 7 sur au moins 50% de ladite portion plane 5, de préférence au moins 70%, de manière à former une zone de contact 6 adéquate. According to another possible additional characteristic, said contact zone 6, formed by the affixing of the strip 2 of paper to the peripheral wall 7 of the container 1 at the level of the flat portion 5, extends over at least 50% (percentages ) of said flat portion 5, preferably at least 70%, in the main direction 15. In other words, at the level of the section considered, forming the flat portion 5 between the lower limit 18 and the upper limit 19, the at at least one strip 2 of paper must be in contact with the peripheral wall 7 over at least 50% of said flat portion 5, preferably at least 70%, so as to form an adequate contact zone 6.
En effet, la zone de contact doit être suffisamment importante pour garantir la cohésion des récipients groupés. Cela est d'autant plus nécessaire en raison du matériau dans lequel la bande 2 est réalisée, le papier étant moins extensible et moins résistant que le plastique. Notamment, dans le cas d'un lot de récipients en Poly téréphtalate d'éthylène (PET), qui sont semi-rigides, une bande 2 de papier qui maintiendrait uniquement les récipients ensemble par la tension exercée, sur quelques points seulement de ces derniers, serait fortement susceptible de se déchirer : lors de leur manutention ou de leur transport, le frottement et la friction entre les récipients solliciteraient fortement les zones d'appui. Indeed, the contact area must be large enough to guarantee the cohesion of the grouped containers. This is all the more necessary because of the material from which the strip 2 is made, paper being less extensible and less resistant than plastic. In particular, in the case of a batch of containers made of Polyethylene terephthalate (PET), which are semi-rigid, a strip 2 of paper which would only hold the containers together by the tension exerted, on only a few points of the latter , would be highly susceptible to tearing: during their handling or transport, rubbing and friction between the containers would strongly stress the bearing areas.
Cette caractéristique a pour avantage de contribuer à la solidité du lot 100, et prévenir tout risque de dislocation dudit lot, par exemple par une rupture de la bande 2 de papier. This feature has the advantage of contributing to the strength of the batch 100, and preventing any risk of dislocation of said batch, for example by breaking the strip 2 of paper.
Dans certains modes de réalisation, le lot 100 comprend une seule bande 2 de papier. Cela a pour avantage de minimiser encore la quantité de déchets produite, tout en conservant un maintien optimal du lot 100. In some embodiments, batch 100 comprises a single strip 2 of paper. This has the advantage of further minimizing the amount of waste produced, while maintaining optimal maintenance of batch 100.
Selon une caractéristique additionnelle possible, dans le cas où le lot 100 comprend une seule bande 2, ladite bande 2 de papier a une hauteur minimale de un huitième de la hauteur H de chacun
des récipients 1 le long de la direction principale 15. De préférence, ladite bande 2 de papier a une hauteur minimale d'un quart de la hauteur H de chacun des récipients 1 le long de la direction principale 15. According to a possible additional characteristic, in the case where lot 100 comprises a single strip 2, said strip 2 of paper has a minimum height of one eighth of the height H of each containers 1 along the main direction 15. Preferably, said strip 2 of paper has a minimum height of a quarter of the height H of each of the containers 1 along the main direction 15.
En outre, selon l'invention, la bande 2 de papier a une hauteur inférieure ou égale à la hauteur de la portion plane 5. En outre, selon certains modes de réalisation, la bande 2 de papier ne s'étend pas en dessous de la limite inférieure 18 et au-dessus de la limite supérieure 19, le long de la direction principale 15 : elle est alors intégralement comprise dans le tronçon de la portion plane 5. Furthermore, according to the invention, the strip 2 of paper has a height less than or equal to the height of the flat portion 5. Furthermore, according to certain embodiments, the strip 2 of paper does not extend below the lower limit 18 and above the upper limit 19, along the main direction 15: it is then entirely included in the section of the plane portion 5.
Dans certains modes de réalisations, le lot 100 comprend au moins deux bandes 2 le long de la direction principale 15, la hauteur totale cumulée desdites bandes représentant au moins un quart de la hauteur H des récipients 1. Préférentiellement, la hauteur cumulée desdites bandes représente au plus deux tiers de la hauteur de chacun des récipients 1 le long de la direction principale 15. La hauteur considérée d'un récipient 1 est sa hauteur H mesurée entre le haut du bouchon 22 et la surface de contact du fond 4 dudit récipient 1. La hauteur H d'un récipient 1 et la hauteur d'une bande 2 se mesurent le long de la direction principale 15. Les au moins deux bandes 20 et 21 de papier sont disposées le long de la direction principale 15. Elles peuvent reposer sur la même portion plane 5 ou, de manière préférentielle, sur deux portions planes 51 et 52 distinctes. In certain embodiments, the batch 100 comprises at least two strips 2 along the main direction 15, the cumulative total height of said strips representing at least a quarter of the height H of the containers 1. Preferably, the cumulative height of said strips represents at most two-thirds of the height of each of the containers 1 along the main direction 15. The considered height of a container 1 is its height H measured between the top of the stopper 22 and the contact surface of the bottom 4 of said container 1 The height H of a container 1 and the height of a strip 2 are measured along the main direction 15. The at least two strips 20 and 21 of paper are arranged along the main direction 15. They can rest on the same flat portion 5 or, preferably, on two separate flat portions 51 and 52.
L'avantage résultant d'une telle hauteur minimale est que la tension exercée sur les récipients 1 est répartie de manière homogène sur la zone de contact 6. Cela va éviter de déformer le corps 3 des récipients 1 de manière trop importante. The advantage resulting from such a minimum height is that the tension exerted on the containers 1 is distributed evenly over the contact zone 6. This will avoid deforming the body 3 of the containers 1 too much.
On comprend que, en fonction du type de récipients 1, de leur hauteur ou encore en fonction du poids total du lot 100, il peut être nécessaire d'utiliser une ou plusieurs bandes 2 de papier pour garantir le maintien optimal des récipients 1 groupés ensemble. It is understood that, depending on the type of containers 1, their height or even depending on the total weight of the lot 100, it may be necessary to use one or more strips 2 of paper to guarantee the optimal maintenance of the containers 1 grouped together .
Il peut également être nécessaire d'adapter la hauteur de la au moins une bande 2 de papier en fonction des différentes configurations ou agencement des récipients 1 ensemble. It may also be necessary to adapt the height of the at least one strip 2 of paper according to the different configurations or arrangement of the containers 1 together.
Selon une caractéristique additionnelle possible, la au moins une portion plane 5 comporte des cannelures 8, lesdites cannelures 8 recouvrant moins de 50% (pourcents), de préférence moins de 30%, de la portion plane 5. According to a possible additional characteristic, the at least one flat portion 5 comprises grooves 8, said grooves 8 covering less than 50% (percents), preferably less than 30%, of the flat portion 5.
Un récipient 1 peut en effet présenter des cannelures 8, à visée esthétique ou technique, de toute forme ou de tout motif, ces cannelures 8 faisant ou non le tour du corps 3 du récipient et étant réparties de manière homogène ou non, symétrique ou non. Un récipient 1 peut également présenter sur son corps des reliefs, des textures, également à visée esthétique, ou à visée informative. Un récipient 1 peut également présenter des gorges, ou des ceintures, à visée technique. Ces cannelures 8, motifs, gorges ou ceintures ne doivent pas représenter plus de 30% de la surface de la portion plane. En effet, la zone de contact 6 entre la ou les bandes 2 de papier et la paroi périphérique 7
du récipient doit représenter préférablement au moins 70% de la portion plane 5, dans la direction principale 15 A container 1 can in fact have grooves 8, for aesthetic or technical purposes, of any shape or pattern, these grooves 8 going around the body 3 of the container or not and being distributed homogeneously or not, symmetrical or not. . A container 1 can also present on its body reliefs, textures, also for aesthetic purposes, or for informative purposes. A container 1 can also have grooves, or belts, for technical purposes. These grooves 8, patterns, grooves or belts must not represent more than 30% of the surface of the flat portion. Indeed, the contact zone 6 between the strip or strips 2 of paper and the peripheral wall 7 of the container must preferably represent at least 70% of the flat portion 5, in the main direction 15
Autrement dit, un tronçon de la paroi périphérique 7 présentant des cannelures 8, dans la direction principale 15, peut être considéré comme une portion plane 5, si la surface des cannelures 8 ne recouvre pas plus de 30% de la surface dudit tronçon. In other words, a section of the peripheral wall 7 having grooves 8, in the main direction 15, can be considered as a flat portion 5, if the surface of the grooves 8 does not cover more than 30% of the surface of said section.
Il est entendu que ces cannelures 8 ou reliefs, ou encore gorges ou ceintures, ne sont pas prises en compte dans le calcul du diamètre ou du périmètre du récipient 1, entre la limite inférieure 18 et la limite supérieure 19 de la portion plane 5, dans la mesure où leurs dimensions ne dépassent pas 10mm (millimètres) de profondeur tous les 100mm, de préférence 4mm de profondeur ou d'altitude sur une section de plus de 8mm de hauteur. En d'autres termes, sur la portion plane 5, une cannelure, un relief ou un motif ne doit pas avoir une profondeur ou une altitude de plus de 10mm (millimètres) sur une section de plus de 8mm de hauteur dans la direction principale 15. It is understood that these grooves 8 or reliefs, or even grooves or belts, are not taken into account in the calculation of the diameter or the perimeter of the container 1, between the lower limit 18 and the upper limit 19 of the flat portion 5, insofar as their dimensions do not exceed 10mm (millimeters) in depth every 100mm, preferably 4mm in depth or elevation over a section of more than 8mm in height. In other words, on the flat portion 5, a groove, a relief or a pattern must not have a depth or an elevation of more than 10mm (millimeters) on a section of more than 8mm in height in the main direction 15 .
En outre, selon une autre caractéristique additionnelle, les bords inférieur 201 et supérieur 202 de la bande 2 de papier ne reposent pas sur un relief ou dans une cannelure 8 mais directement sur la zone de contact 6 au niveau de la paroi périphérique 7. Furthermore, according to another additional characteristic, the lower 201 and upper 202 edges of the strip 2 of paper do not rest on a relief or in a groove 8 but directly on the contact zone 6 at the level of the peripheral wall 7.
Dans d'autres modes de réalisation, le lot 100 comprend au moins quatre récipients 1, au moins un sous-lot 101 comprenant au moins deux desdits récipients 1, au moins un bandeau 13 de papier fermé qui maintient groupés ensemble lesdits récipients 1 formant le sous-lot 101, au moins une bande 2 de papier fermée enrobant ledit lot 100 au niveau d'une portion plane 5 de chacun desdits récipients 1, de sorte à former une zone de contact 6 entre ladite portion plane 5 et ladite au moins une bande 2. In other embodiments, the batch 100 comprises at least four containers 1, at least one sub-batch 101 comprising at least two of said containers 1, at least one strip 13 of closed paper which holds together said containers 1 forming the sub-batch 101, at least one closed strip 2 of paper coating said batch 100 at the level of a flat portion 5 of each of said containers 1, so as to form a contact zone 6 between said flat portion 5 and said at least one band 2.
Une telle configuration est particulièrement avantageuse, la solidité du lot 100 étant renforcée. En effet, dans le cas où plus de quatre récipients 1 sont groupés ensemble, la zone de contact 6 totale est réduite pour certains des récipients 1. En particulier, les récipients 1 situés au centre du lot auront tendance à glisser contre les parois des récipients 1 situés aux angles du lot 100. Ce phénomène est d'autant plus important quand les récipients ont une section arrondie, globalement circulaire ou ovoïdale, qui plus est dans le cas de récipients en matière plastique. Dans un tel cas, le lot 100 subit des déformations ce qui est susceptible d'entraîner son démantèlement lors de sa manutention. Par ailleurs, on comprend que la bande 2 de papier recouvre une portion moindre de la paroi périphérique 7 des récipients 1 situés au centre du lot 100, par rapport aux récipients 1 situés dans les coins dudit lot 100. Dans une telle configuration, il est donc préférable de doubler l'enrobage, et donc de subdiviser le lot 100 en un ou plusieurs sous-lots 101.
Selon des caractéristiques additionnelles, chaque sous-lot 101 peut rassembler au plus quatre récipients 1. Chaque sous-lot 101 peut s'étendre transversalement, c'est-à-dire de long des colonnes du lot 100, ou encore longitudinalement, c'est-à-dire le long des rangées dudit lot. Le ou les sous- lots 101 seront avantageusement orientés en fonction du nombre de récipients 1 formant le lot 100, afin d'optimiser sa solidité. Autrement dit, selon un mode de réalisation préféré, un sous-lot 101 est composé d'au moins un récipient 1 présentant une zone de contact 6 importante, par exemple un ou des récipients 1 situés à un angle du lot 100, et d'au moins un récipient 1 présentant une zone de contact 6 amoindrie, par exemple un ou des récipients 1 situés au centre dudit lot 100. Il est entendu qu'ici la zone de contact 6 maximale possible est liée à l'emplacement du récipient 1 au sein du lot 100. Chaque sous-lot 101 assurera le maintien ensemble des récipients 1 le composant. Dans le cadre de la manutention ou du transport du lot 100 ainsi formé, le ou les sous-lots 101 minimiseront le frottement relatif et le déplacement des récipients 1, en particulier des récipients situés au centre dudit lot 100. En effet, chaque récipient 1 sera alors maintenu fermement, soit directement, au moyen de la au moins une bande 2 de papier, soit au moyen d'un double enrobage, c'est-à-dire directement au moyen du au moins un bandeau 13 de papier et indirectement au moyen de la au moins une bande 2 de papier. On comprend qu'en fonction du nombre de récipients 1, il n'est pas toujours nécessaire d'entourer tous les récipients 1 sous la forme d'un sous-lot 101 préalablement à l'enrobage d'un lot 100. En d'autres termes, dans certains modes de réalisation, certains récipients 1 ne sont pas entourés par un bandeau 13 pour former un sous-lot 101, avant d'être enrobés pour former un lot 100. Such a configuration is particularly advantageous, the solidity of the lot 100 being reinforced. Indeed, in the case where more than four containers 1 are grouped together, the total contact area 6 is reduced for some of the containers 1. In particular, the containers 1 located in the center of the batch will tend to slide against the walls of the containers 1 located at the corners of lot 100. This phenomenon is all the more important when the containers have a rounded section, generally circular or ovoid, which is more in the case of plastic containers. In such a case, the batch 100 undergoes deformations which is likely to lead to its dismantling during its handling. Furthermore, it is understood that the strip 2 of paper covers a smaller portion of the peripheral wall 7 of the containers 1 located in the center of the lot 100, compared to the containers 1 located in the corners of said lot 100. In such a configuration, it is therefore preferable to double the coating, and therefore to subdivide lot 100 into one or more sub-lots 101. According to additional characteristics, each sub-batch 101 can bring together at most four containers 1. Each sub-batch 101 can extend transversely, that is to say along the columns of the batch 100, or even longitudinally, it i.e. along the rows of said lot. The sub-batch or batches 101 will advantageously be oriented according to the number of containers 1 forming the batch 100, in order to optimize its solidity. In other words, according to a preferred embodiment, a sub-batch 101 is composed of at least one container 1 having a large contact zone 6, for example one or more containers 1 located at an angle of the batch 100, and of at least one container 1 having a reduced contact area 6, for example one or more containers 1 located in the center of said lot 100. It is understood that here the maximum possible contact area 6 is linked to the location of the container 1 at the within batch 100. Each sub-batch 101 will ensure that the containers 1 component are kept together. As part of the handling or transport of the batch 100 thus formed, the sub-batches 101 will minimize the relative friction and the displacement of the containers 1, in particular the containers located in the center of said batch 100. Indeed, each container 1 will then be firmly held, either directly, by means of the at least one strip 2 of paper, or by means of a double coating, that is to say directly by means of the at least one strip 13 of paper and indirectly by means of the means of the at least one strip 2 of paper. It is understood that depending on the number of containers 1, it is not always necessary to surround all the containers 1 in the form of a sub-batch 101 prior to the coating of a batch 100. other words, in certain embodiments, certain containers 1 are not surrounded by a band 13 to form a sub-batch 101, before being coated to form a batch 100.
Dans certains modes de réalisation, la au moins une bande 2 est fermée par recouvrement de ses extrémités opposées 16 et 17. L'adhésion entre les deux extrémités opposées 16 et 17 est réalisée au moyen d'une soudure activée par ultrasons. Elle peut également être réalisée par collage, par activation thermique (thermo scellage), agrafes, par ou par tout autre moyen. Ces modes de réalisation, concernant la fermeture de la bande 2 de papier, s'appliquent également à le au moins un bandeau 13 de papier dans le cas où le lot 100 comprend au moins un sous-lot 101. In certain embodiments, the at least one strip 2 is closed by overlapping its opposite ends 16 and 17. The adhesion between the two opposite ends 16 and 17 is achieved by means of a weld activated by ultrasound. It can also be made by gluing, by thermal activation (thermo sealing), staples, by or by any other means. These embodiments, concerning the closure of the strip 2 of paper, also apply to the at least one strip 13 of paper in the case where the batch 100 includes at least one sub-batch 101.
Il convient de noter que la position de la bande 2 de papier, au niveau d'une portion plane 5 des récipients 1 améliore la tenue mécanique de la jointure de la bande 2 de papier, qui est moins sollicitée par des frottements provoqués par un mouvement des récipients 1 au sein du lot 100. La jointure des deux extrémités opposées de la bande 2 de papier présente des caractéristiques de résistance au moins équivalentes à celles de la bande 2 de papier. It should be noted that the position of the strip 2 of paper, at the level of a flat portion 5 of the containers 1 improves the mechanical strength of the joint of the strip 2 of paper, which is less stressed by friction caused by a movement containers 1 within batch 100. The join of the two opposite ends of the strip 2 of paper has strength characteristics at least equivalent to those of the strip 2 of paper.
Selon une autre caractéristique additionnelle possible, la au moins une bande 2 présente un revêtement 9 sur sa face extérieure, du type peinture, colle, laque ou traitement. La face extérieure de la bande 2 de papier est la face visible de ladite bande 2 lorsqu'elle enrobe le lot 100. According to another possible additional characteristic, the at least one strip 2 has a coating 9 on its outer face, of the paint, glue, lacquer or treatment type. The outer face of strip 2 of paper is the visible face of said strip 2 when it coats lot 100.
Le revêtement 9 peut recouvrir les deux faces de la au moins une bande 2, ou une seule de ses faces. Dans un mode de réalisation, la bande 2 de papier présente un revêtement 9 sur sa face
intérieure, c'est-à-dire la face qui est en contact avec la portion plane 5 des récipients 1. Ce revêtement 9 peut donc couvrir l'intégralité d'une des deux faces, ou être réalisé de manière discontinue, ou encore couvrir partiellement la longueur de la bande, par exemple uniquement à l'une des extrémités 16 ou 17. Ce revêtement 9 peut être un revêtement à visée purement esthétique, de type vernis ou laque par exemple, pour améliorer le rendu visuel du produit, ou encore à visée technique, par exemple pour faciliter l'impression d'informations, de messages, de dessins, de signes, etc. Coating 9 can cover both sides of at least one strip 2, or only one of its sides. In one embodiment, the strip 2 of paper has a coating 9 on its face interior, that is to say the face which is in contact with the flat portion 5 of the containers 1. This coating 9 can therefore cover the entirety of one of the two faces, or be produced discontinuously, or even cover partially the length of the strip, for example only at one of the ends 16 or 17. This coating 9 can be a purely aesthetic coating, of the varnish or lacquer type for example, to improve the visual rendering of the product, or even for technical purposes, for example to facilitate the printing of information, messages, drawings, signs, etc.
Notamment, selon un mode de réalisation, ce revêtement 9 est un revêtement à visée technique, notamment un revêtement thermoscellant afin de favoriser l'adhésion des deux extrémités opposées 16 et 17 de la au moins une bande 2 de papier. Un tel revêtement 9 thermoscellant est activé par ultrasons ou thermiquement. Ce mode de réalisation permet avantageusement d'activer les propriétés de scellement de manière localisée. En d'autres termes, avant activation, le revêtement 9 est inactif, c'est-à-dire inapte à jouer un rôle adhésif, et après activation, il revêt des propriétés adhésives. Selon une autre variante, le revêtement 9 thermoscellant recouvre l'intégralité de la face intérieure de la bande 2 de papier, et est activé localement, par exemple par ultrasons, pour former une ou plusieurs zones adhésives. Dans ce mode de réalisation, l'activation dudit revêtement 9 thermoscellant peut être réalisée de manière ciblée au niveau de la zone de contact 6 entre la au moins une bande 2 de papier et la paroi périphérique 7 d'un ou plusieurs récipients 1. In particular, according to one embodiment, this coating 9 is a coating for technical purposes, in particular a heat-sealing coating in order to promote the adhesion of the two opposite ends 16 and 17 of the at least one strip 2 of paper. Such a heat-sealing coating 9 is activated by ultrasound or thermally. This embodiment advantageously makes it possible to activate the sealing properties in a localized manner. In other words, before activation, the coating 9 is inactive, that is to say unable to play an adhesive role, and after activation, it takes on adhesive properties. According to another variant, the heat-sealing coating 9 covers the entire inner face of the strip 2 of paper, and is activated locally, for example by ultrasound, to form one or more adhesive zones. In this embodiment, the activation of said heat-sealing coating 9 can be carried out in a targeted manner at the level of the contact zone 6 between the at least one strip 2 of paper and the peripheral wall 7 of one or more containers 1.
Selon d'autres caractéristiques additionnelles, le revêtement 9 peut être destiné à améliorer le coefficient de frottement, ou encore à améliorer la résistance à l'humidité de la bande 2 de papier. According to other additional characteristics, the coating 9 may be intended to improve the coefficient of friction, or even to improve the resistance to humidity of the strip 2 of paper.
Dans des modes de réalisation où le lot 100 comprend au moins un sous-lot 101, le au moins un bandeau 13 de papier peut également présenter un revêtement 9. Ainsi, la ou les bandes 2 et le ou les bandeaux 13 peuvent présenter le même revêtement 9. La ou les bandes 2 et le ou les bandeaux 13 peuvent présenter un revêtement 9 différent, ou encore aucun revêtement 9. Le revêtement 9 peut être de la laque, de la peinture, ou encore être un traitement de surface à visée technique, tel qu'un traitement thermoscellant, activable à l'eau, ou à visée esthétique. In embodiments where the batch 100 comprises at least one sub-batch 101, the at least one strip 13 of paper can also have a coating 9. Thus, the strip or strips 2 and the strip or strips 13 can have the same coating 9. The strip(s) 2 and the band(s) 13 may have a different coating 9, or even no coating 9. The coating 9 may be lacquer, paint, or even be a surface treatment for technical purposes , such as a heat-sealing treatment, which can be activated with water, or for aesthetic purposes.
Selon une autre caractéristique additionnelle possible, le lot 100 comprend un moyen d'adhésion additionnel 10 au niveau de la zone de contact 6, entre la portion plane 5 et la bande 2. Le moyen additionnel 10 peut être placé initialement soit sur la paroi périphérique 7, au niveau de la portion plane 5, soit sur la face intérieure de la bande 2 correspondante, soit les deux. Avant enrobage du lot 100 par la bande 2 de papier, ledit moyen d'adhésion additionnel 10 peut être placé soit sur la paroi périphérique 7 du récipient 1, au niveau de la portion plane 5, soit sur la face intérieure de la bande 2 de papier, soit les deux. Ce moyen d'adhésion additionnel 10 permet d'améliorer le maintien en position de la bande 2 de papier.
Ce moyen d'adhésion additionnel peut par exemple être un ou plusieurs points de colle, ou encore du ruban adhésif double face. Selon une caractéristique additionnelle, ce moyen d'adhésion additionnel 10 est un revêtement 9 thermoscellant, local ou non, activable par ultrasons ou thermiquement. Dans des modes de réalisation où le récipient 1 présente une étiquette 14, collée sur son corps 3, et où la portion plane 5 se situe dans cette même zone, donc au niveau de l'étiquette 14, le moyen d'adhésion additionnel 10 ne se situe pas sur l'étiquette 14 mais à sa périphérie. En effet, il est essentiel de préserver l'intégrité de ladite étiquette. According to another possible additional characteristic, the batch 100 comprises an additional adhesion means 10 at the level of the contact zone 6, between the flat portion 5 and the strip 2. The additional means 10 can be placed initially either on the peripheral wall 7, at the flat portion 5, either on the inner face of the corresponding strip 2, or both. Before the batch 100 is coated with the strip 2 of paper, said additional adhesion means 10 can be placed either on the peripheral wall 7 of the container 1, at the level of the flat portion 5, or on the inside face of the strip 2 of paper, or both. This additional adhesion means 10 makes it possible to improve the holding in position of the strip 2 of paper. This additional adhesion means may for example be one or more dots of glue, or even double-sided adhesive tape. According to an additional characteristic, this additional adhesion means 10 is a heat-sealing coating 9, local or not, which can be activated by ultrasound or thermally. In embodiments where the container 1 has a label 14, glued to its body 3, and where the flat portion 5 is located in this same zone, therefore at the level of the label 14, the additional adhesion means 10 does not is not located on the label 14 but on its periphery. Indeed, it is essential to preserve the integrity of said label.
En outre, dans une configuration où le lot 100 est subdivisé en un ou plusieurs sous-lots 101, ce moyen d'adhésion additionnel 10, avant entourage, peut se présenter sur la face intérieure du ou des bandeaux 13 de papier enrobant les récipients 1 formant le ou les sous-lots 101. Ledit moyen d'adhésion additionnel 10 peut également, de manière cumulative ou alternative, se présenter sur la face extérieure du ou des bandeaux 13 de papier, afin d'améliorer la liaison entre la au moins une bande 2 de papier et le ou les bandeaux 13 de papier. Ce mode de réalisation a pour avantage d'améliorer la cohésion du lot 100. In addition, in a configuration where the batch 100 is subdivided into one or more sub-batches 101, this additional adhesion means 10, before surrounding, can be present on the inner face of the strip or strips 13 of paper coating the containers 1 forming the sub-batch or batches 101. Said additional adhesion means 10 can also, cumulatively or alternatively, be present on the outer face of the strip or strips 13 of paper, in order to improve the bond between the at least one strip 2 of paper and the strip or strips 13 of paper. This embodiment has the advantage of improving the cohesion of the lot 100.
Il est entendu que ce moyen d'adhésion additionnel 10 concerne l'adhésion entre la bande 2 ou le bandeau 13 et un ou plusieurs récipients 1, et non l'adhésion entre deux récipients 1. Autrement dit, le moyen d'adhésion additionnel 10 se situe à l'interface entre au moins une bande 2 de papier et le au moins un bandeau 13 de papier et/ou à l'interface entre la au moins une bande 2 de papier et la paroi périphérique 7 d'un ou de plusieurs récipients 1. It is understood that this additional adhesion means 10 relates to the adhesion between the band 2 or the strip 13 and one or more containers 1, and not the adhesion between two containers 1. In other words, the additional adhesion means 10 is located at the interface between at least one strip 2 of paper and the at least one strip 13 of paper and/or at the interface between the at least one strip 2 of paper and the peripheral wall 7 of one or more containers 1.
Enfin, selon une caractéristique additionnelle possible, le lot 100 comprend une poignée 11 sous la forme d'au moins une sangle 12. La sangle 12 permet de saisir et de soulever le lot 100 par le dessus dudit lot, dans une orientation normale. Cette sangle 12 peut être fixée par recouvrement partiel d'au moins une bande 2 de papier. Finally, according to a possible additional characteristic, the batch 100 comprises a handle 11 in the form of at least one strap 12. The strap 12 makes it possible to grasp and lift the batch 100 from above said batch, in a normal orientation. This strap 12 can be fixed by partial covering of at least one strip 2 of paper.
Selon une autre variante, chaque extrémité de la sangle 12 peut être prise en sandwich entre un bandeau 13 de papier d'un sous-lot 101 et une bande 2 de papier du lot 100. According to another variant, each end of the strap 12 can be sandwiched between a strip 13 of paper from a sub-batch 101 and a strip 2 of paper from batch 100.
Selon une autre caractéristique possible, la sangle 12 est fixée à la fois par recouvrement partiel d'au moins une bande 2 de papier et sur une portion de la paroi périphérique de deux récipients 1. Dans une telle configuration, la sangle 12 se prolonge au-delà de la au moins une bande 2 et est fixée sur la portion de la paroi périphérique 7 du récipient 1 se situant en dessous de ladite bande 2, dans le sens de la direction principale 15. De manière facultative, la sangle 12 peut également être fixée sur la portion de la paroi périphérique 7 se situant au-dessus de ladite bande 2, dans le sens de la direction principale 15. According to another possible characteristic, the strap 12 is fixed both by partial covering of at least one strip 2 of paper and on a portion of the peripheral wall of two containers 1. In such a configuration, the strap 12 extends to the -beyond the at least one strip 2 and is attached to the portion of the peripheral wall 7 of the container 1 located below said strip 2, in the direction of the main direction 15. Optionally, the strap 12 can also be fixed on the portion of the peripheral wall 7 located above said strip 2, in the direction of the main direction 15.
Ce mode de réalisation est particulièrement avantageux car il permet une collaboration entre la sangle 12 formant la poignée 11 et la bande 2 de papier assurant l'intégrité du lot 100. Lors du soulèvement dudit lot 100, la sangle 12 contribuera au maintien en position de la bande 2. Dans ce
mode de réalisation, la sangle 12 est fixée, au moyen d'un ruban adhésif double face ou par des points de colle, sur une partie de la paroi périphérique 7, en sus de sa fixation sur la au moins une bande 2 de papier. Ce mode de réalisation est particulièrement avantageux lorsque le lot 100 ne comprend pas de sous-lots 101. En outre, cette variante permet de réaliser un lot 100 de plus de quatre récipients sans former de sous-lots 101 préalablement et donc d'obtenir un maintien optimal tout en utilisant peu de matières premières, ce qui est un avantage écologique. This embodiment is particularly advantageous because it allows collaboration between the strap 12 forming the handle 11 and the strip 2 of paper ensuring the integrity of the lot 100. When lifting said lot 100, the strap 12 will contribute to maintaining the position of the band 2. In this embodiment, the strap 12 is fixed, by means of a double-sided adhesive tape or by glue dots, on a part of the peripheral wall 7, in addition to its fixing on the at least one strip 2 of paper. This embodiment is particularly advantageous when the batch 100 does not include sub-batches 101. In addition, this variant makes it possible to produce a batch 100 of more than four containers without forming sub-batches 101 beforehand and therefore to obtain a optimal support while using few raw materials, which is an ecological advantage.
Selon une autre caractéristique possible, la sangle 12 est réalisée dans un matériau différent de la bande 2 de papier. En particulier, selon une variante, la sangle 12 présente plusieurs zones adhésives sur sa face intérieure. Dans un mode de réalisation, la sangle 12 présente un revêtement 9 thermoscellant sur sa face intérieure. La sangle 12 est alors fixée par activation thermique ou au moyen d'ultrasons. According to another possible characteristic, the strap 12 is made of a different material from the strip 2 of paper. In particular, according to a variant, the strap 12 has several adhesive areas on its inner face. In one embodiment, the strap 12 has a heat-sealing coating 9 on its inside face. The strap 12 is then fixed by thermal activation or by means of ultrasound.
Dans certains modes de réalisation, chacun des récipients 1 comprend une étiquette 14 entourant le pourtour de leur paroi périphérique 7 sur une partie de la hauteur desdits récipients 1. La bande 2 de papier recouvre alors préférablement au moins partiellement voire totalement la hauteur de ladite étiquette 14 lorsque ladite bande enrobe lesdits récipients 1 pour former le lot 100. In certain embodiments, each of the containers 1 comprises a label 14 surrounding the periphery of their peripheral wall 7 over part of the height of said containers 1. The strip 2 of paper then preferably covers at least partially or even totally the height of said label. 14 when said strip coats said containers 1 to form batch 100.
L'invention concerne également une bande 2 de maintien en papier pour un lot 100 tel que défini plus haut. The invention also relates to a paper holding strip 2 for a batch 100 as defined above.
Selon une caractéristique additionnelle possible, la bande 2 de maintien est réalisée en un matériau en papier, à base de fibres végétales. Selon l'invention, la bande 2 de papier contient une quantité limitée de polymères, à savoir une quantité inférieure à 30%, de préférence inférieure à 10%, de la masse totale. La composition de la bande 2 de maintien lui permet de satisfaire les critères de la norme EN13430 en matière de recyclabilité. According to a possible additional characteristic, the holding strip 2 is made of a paper material, based on vegetable fibers. According to the invention, the strip 2 of paper contains a limited quantity of polymers, namely a quantity of less than 30%, preferably less than 10%, of the total mass. The composition of the retaining band 2 allows it to meet the criteria of standard EN13430 in terms of recyclability.
Cette bande 2 de maintien, dans certains modes de réalisation, est réalisée dans un papier présentant un grammage compris entre 50 et 150g/m2 (gramme par mètre carré), de préférence compris entre 90 et 120g/m2. En outre, selon d'autres caractéristiques, la bande 2 présente une résistance accrue ce qui limite les risques de démantèlement du lot 100 ou de dégroupage des récipients 1. This holding strip 2, in certain embodiments, is made of a paper having a weight of between 50 and 150 g/m2 (gram per square meter), preferably between 90 and 120 g/m2. In addition, according to other characteristics, the strip 2 has increased resistance, which limits the risks of dismantling the batch 100 or unbundling the containers 1.
Dans des modes de réalisation où le lot 100 comprend un ou plusieurs sous-lots 101, le bandeau 13 de papier présente des propriétés similaires à la bande 2 en termes de matériau. Autrement dit, le bandeau 13 est réalisé en papier, à base de fibres végétales, et sa composition contient tout au plus 30% de polymères, de préférence 10%. Son grammage peut être identique ou non à celui de la bande 2 de papier. En particulier, le bandeau 13 de papier peut être d'une épaisseur inférieure à l'épaisseur de la bande 2 de papier. In embodiments where batch 100 comprises one or more sub-batches 101, strip 13 of paper has properties similar to strip 2 in terms of material. In other words, the band 13 is made of paper, based on plant fibers, and its composition contains at most 30% polymers, preferably 10%. Its weight may or may not be identical to that of strip 2 of paper. In particular, the strip 13 of paper may be of a thickness less than the thickness of the strip 2 of paper.
Selon une autre caractéristique additionnelle, la bande 2 de papier est telle, que, une fois le lot 100 formé, elle exerce une force comprise entre 0.2 et 5kN/m (kilonewton par mètre), de
préférence comprise entre 0.2 et lkN/m, au niveau de la portion plane 5. Par exemple, pour une bande 2 de papier d'une hauteur de 50mm, la force appliquée est comprise entre 10 et 50N. Cette force appliquée contribue au maintien ensemble des récipients 1 sous la forme d'un lot compact 100. Ce mode de réalisation est particulièrement avantageux dans le cas où les récipients 1 sont semi- rigides. According to another additional characteristic, the strip 2 of paper is such that, once the batch 100 has been formed, it exerts a force of between 0.2 and 5kN/m (kilonewton per meter), of preferably between 0.2 and 1kN/m, at the flat portion 5. For example, for a strip 2 of paper with a height of 50mm, the force applied is between 10 and 50N. This applied force contributes to the holding together of the containers 1 in the form of a compact batch 100. This embodiment is particularly advantageous in the case where the containers 1 are semi-rigid.
L'invention a aussi pour objet un procédé pour le conditionnement du lot 100 susmentionné, dans lequel on regroupe au moins deux récipients 1. The invention also relates to a method for packaging the aforementioned batch 100, in which at least two containers 1 are grouped together.
Selon l'invention, ce procédé se caractérise en ce qu'il comprend au moins les étapes suivantes According to the invention, this method is characterized in that it comprises at least the following steps
-on effectue un enrobage du lot par au moins une bande 2 au niveau de la au moins une portion plane 5 de chacun desdits récipients 1, - the batch is coated with at least one strip 2 at the level of the at least one flat portion 5 of each of said containers 1,
- on appose ladite au moins une bande 2 avec une tension suffisante pour le maintien desdits au moins deux récipients 1 en lot 100. - said at least one strip 2 is affixed with sufficient tension to hold said at least two containers 1 in batch 100.
Selon une caractéristique additionnelle possible, dans un tel procédé de conditionnement, on peut rassembler les récipients 1 en un ou plusieurs sous-lots 101. According to a possible additional characteristic, in such a packaging method, the containers 1 can be grouped together in one or more sub-batches 101.
Dans un tel mode de réalisation : on effectue un groupage d'au moins deux récipients 1 en au moins un sous-lot 101 ; on entoure chaque sous-lot 101 au moyen d'un bandeau 13 de papier ; on enrobe le ou les sous-lots 101 en lot 100. In such an embodiment: at least two containers 1 are grouped into at least one sub-batch 101; each sub-batch 101 is surrounded by a band 13 of paper; the sub-batch or batches 101 are coated in batch 100.
Selon une caractéristique additionnelle possible, au moins un récipient 1 ne fait pas partie d'un sous-lot 101. En d'autres termes, certains récipients 1 peuvent être regroupés en sous-lot 101, puis entourés par au moins un bandeau 13 de papier, alors que d'autres récipients 1 restent libres avant d'être enrobés, avec le ou les sous-lots 101, au moyen d'au moins une bande 2 de papier, pour former un lot 100. According to a possible additional characteristic, at least one container 1 is not part of a sub-batch 101. In other words, certain containers 1 can be grouped together in a sub-batch 101, then surrounded by at least one strip paper, while other containers 1 remain free before being coated, with the sub-batch(s) 101, by means of at least one strip 2 of paper, to form a batch 100.
Dans des modes de réalisation, avant enrobage du lot 100, on peut composer le ou les sous- lots 101 selon une orientation transversale et/ou longitudinale par rapport à la plus grande dimension de la matrice que forme le lot 100 afin d'optimiser la solidité du lot 100. Autrement dit, il est possible de grouper en un ou plusieurs sous-lots 101 des récipients 1 formant tout ou partie d'une rangée ou formant tout ou partie d'une colonne au sein du lot 100. Un sous-lot 101 est composé au plus de quatre récipients 1, de préférence de deux récipients 1. Il est également envisageable d'avoir des configurations multiples, avec un agencement de sous-lots 101 répartis transversalement et longitudinalement par rapport au lot 100. Une configuration d'un lot 100, comprenant un ou plusieurs sous-lots 101, disposés en diagonale par rapport au lot 100, est également possible. In some embodiments, before coating the batch 100, the sub-batches 101 can be composed according to a transverse and/or longitudinal orientation with respect to the largest dimension of the matrix formed by the batch 100 in order to optimize the strength of batch 100. In other words, it is possible to group into one or more sub-batches 101 containers 1 forming all or part of a row or forming all or part of a column within batch 100. A sub-batch batch 101 is composed of at most four containers 1, preferably two containers 1. It is also possible to have multiple configurations, with an arrangement of sub-batches 101 distributed transversely and longitudinally with respect to batch 100. A configuration of A lot 100, comprising one or more sub-lots 101, arranged diagonally with respect to lot 100, is also possible.
Avant entourage d'un sous-lot 101,
- on peut appliquer en face intérieure de chaque bandeau 13 de papier, un moyen d'adhésion 10, situé au niveau de la zone de contact 6 de chaque récipient 1 d'un sous-lot 101 ; Before surrounding a sub-lot 101, - Can be applied on the inside of each strip 13 of paper, an adhesion means 10, located at the contact zone 6 of each container 1 of a sub-batch 101;
- on peut appliquer en face extérieure d'au moins un bandeau 13 de papier, un moyen d'adhésion 10 additionnel situé au niveau de zones d'accolement entre deux sous-lots, ou entre un sous-lot 101 et un ou plusieurs récipients 1 ; et/ou - can be applied to the outer face of at least one strip 13 of paper, an additional adhesion means 10 located at the level of adjoining zones between two sub-batches, or between a sub-batch 101 and one or more containers 1; and or
- avant enrobage, on peut appliquer en face intérieure de la au moins une bande 2 un moyen d'adhésion 10. - before coating, an adhesion means 10 can be applied to the inside face of the at least one strip 2.
Enfin, dans certains modes de réalisation, le procédé de conditionnement comprend une étape de fixation d'une poignée 11 sous la forme d'au moins une sangle 12. Préférentiellement, ladite sangle 12 est fixée par ses extrémités opposées en face intérieure de la bande 2 de papier, par recouvrement partiel, avant enrobage. Elle peut également être fixée après enrobage du lot 100, en face extérieure de la bande 2 de papier. Finally, in certain embodiments, the packaging method comprises a step of fixing a handle 11 in the form of at least one strap 12. Preferably, said strap 12 is fixed by its opposite ends on the inside face of the band 2 of paper, by partial covering, before coating. It can also be fixed after coating batch 100, on the outer face of strip 2 of paper.
Dans d'autres modes de réalisation, l'étape de fixation d'une poignée 11 sous la forme d'au moins une sangle 12 est réalisée par la fixation à la fois par recouvrement de la au moins une bande 2 de maintien, sur sa face extérieure, mais également par la fixation de ladite sangle 12 sur une portion de la paroi périphérique 7 des récipients 1. De manière préférée, ladite sangle 12 est fixée par des points de colle en-dessous de la au moins une bande 2, dans la direction principale 15. Ainsi, la sangle 12 recouvre la au moins une bande 2 de part et d'autre du lot 100, et chacune de ses extrémités vient se fixer sur une portion de la paroi périphérique 7 d'un récipient 1, se situant en dessous de ladite au moins une bande 2, dans la direction principale 15. Dans un mode de réalisation où le lot 100 est formé au moyen de deux bandes 2, la sangle 12 peut recouvrir chacune desdites bandes 2 ou une seule desdites bandes 2. In other embodiments, the step of fixing a handle 11 in the form of at least one strap 12 is carried out by fixing both by covering the at least one holding band 2, on its external face, but also by fixing said strap 12 on a portion of the peripheral wall 7 of the containers 1. Preferably, said strap 12 is fixed by glue dots below the at least one strip 2, in the main direction 15. Thus, the strap 12 covers the at least one band 2 on either side of the batch 100, and each of its ends is fixed on a portion of the peripheral wall 7 of a container 1, located below said at least one strip 2, in the main direction 15. In an embodiment where the lot 100 is formed by means of two strips 2, the strap 12 can cover each of said strips 2 or only one of said strips 2 .
Selon une autre caractéristique additionnelle possible, dans le cas où le lot 100 comprend un ou plusieurs sous-lots 101, après entourage, on peut fixer une poignée 11 sous forme d'au moins une sangle 12 en recouvrement partiel d'au moins un bandeau 13 d'un des sous-lots 101. Puis, au moment de l'enrobage dudit sous-lot 101, on peut recouvrir ladite sangle 12, au niveau de la portion d'accolement avec le au moins un bandeau 13, avec la bande 2 formant le lot 100. Cette fixation en sandwich de la sangle 12 entre un bandeau 13 et une bande 2 améliore la résistance et le maintien à ce niveau de la poignée 11. According to another possible additional characteristic, in the case where the lot 100 comprises one or more sub-lots 101, after wrapping, a handle 11 can be fixed in the form of at least one strap 12 partially overlapping at least one band 13 of one of the sub-batches 101. Then, when said sub-batch 101 is coated, said strap 12 can be covered, at the level of the adjoining portion with the at least one band 13, with the band 2 forming lot 100. This sandwich fastening of the strap 12 between a headband 13 and a band 2 improves the resistance and the maintenance at this level of the handle 11.
Dès lors, le lot 100 de récipients ainsi conditionné présente une résistance accrue et limite les risques de démantèlement du lot 100 ou de dégroupage des récipients 1. En effet, les récipients 1, maintenus en sous-lots 101, possèdent d'une part une surface de contact plus importante avec le bandeau 13 de papier qui relie des récipients 1 ensemble dans un même sous-lot 101 et, d'autre part,
une zone d'accolement plus grande entre les sous-lots 101 d'un même lot 100 ceint par la bande 2 de papier. Consequently, the batch 100 of containers thus packaged has increased resistance and limits the risks of dismantling of the batch 100 or of unbundling of the containers 1. Indeed, the containers 1, maintained in sub-batches 101, have on the one hand a larger contact surface with the strip 13 of paper which connects the containers 1 together in the same sub-batch 101 and, on the other hand, a larger adjoining zone between the sub-lots 101 of the same lot 100 surrounded by the strip 2 of paper.
En outre, le doublage de l'enrobage augmente la résistance du lot 100 formé, au regard de ce matériau présentant une fragilité certaine, qui habituellement exclut son utilisation pour des récipients 1, surtout de section arrondie et/ou en matériau plastique. Par ailleurs, dans des modes de réalisation où le lot 100 comprend plus de quatre récipients 1, cela permet d'assurer le maintien ensemble des récipients 1, quelle que soit leur position au sein dudit lot 100. In addition, the doubling of the coating increases the resistance of the batch 100 formed, with regard to this material having a certain fragility, which usually excludes its use for containers 1, especially of rounded section and/or made of plastic material. Moreover, in embodiments where the batch 100 comprises more than four containers 1, this makes it possible to ensure that the containers 1 are kept together, regardless of their position within said batch 100.
Des modes de réalisation possibles vont maintenant être décrits. Possible embodiments will now be described.
Dans un premier mode de réalisation, tel qu'illustré à la figure 1, quatre récipients 1, de section rectangulaire ou sensiblement rectangulaire sont groupés. Les récipients 1 sont maintenus ensemble par la bande 2 de papier, formant un lot 100. La bande 2 de papier encercle donc les récipients 1 de manière à former une cohésion mécanique et un lot 100 compact : dans le cadre de sa manutention, si le lot 100 est déplacé par la préhension d'un seul des récipients 1, tous les récipients 1 restent solidaires et sont également déplacés, soulevés, à savoir soulevés de façon inséparable les uns des autres au sein d'un même lot. In a first embodiment, as shown in Figure 1, four containers 1, of rectangular or substantially rectangular section are grouped. The containers 1 are held together by the strip 2 of paper, forming a batch 100. The strip 2 of paper therefore encircles the containers 1 so as to form mechanical cohesion and a compact batch 100: in the context of its handling, if the batch 100 is moved by gripping only one of the containers 1, all the containers 1 remain attached and are also moved, lifted, namely lifted inseparably from each other within the same batch.
Pour ce faire, la bande 2 de papier entoure les récipients 1, groupés sous forme de matrice. Ladite bande 2 est apposée autour des récipients groupés au niveau de la portion plane 5 selon une direction perpendiculaire ou sensiblement perpendiculaire à la direction principale 15, à savoir orthogonalement par rapport à la hauteur des récipients 1. Autrement dit, la bande 2 de papier enrobe l'ensemble formé par les récipients 1 en s'apposant sur une portion plane 5 du corps 3 de chacun des récipients 1 formant le lot 100. To do this, the strip 2 of paper surrounds the containers 1, grouped in the form of a matrix. Said band 2 is affixed around the containers grouped at the flat portion 5 in a direction perpendicular or substantially perpendicular to the main direction 15, namely orthogonally to the height of the containers 1. In other words, the strip 2 of paper coats the assembly formed by the containers 1 by resting on a flat portion 5 of the body 3 of each of the containers 1 forming the batch 100.
Dans cet exemple de réalisation de l'invention, le récipient 1 a une hauteur de 400mm (millimètres), et comprend un tronçon d'une hauteur de 120mm. Sur ce tronçon, la différence entre le diamètre au niveau de la limite inférieure 18 et le diamètre au niveau de la limite supérieure 19 est de 3mm. Ainsi, ce tronçon peut être considéré comme une portion plane 5. En outre, ledit tronçon, dans cet exemple, ne comporte pas de cannelures 8 ou autre motif. La bande 2 de papier a une hauteur de 100mm et enrobe les récipients 1, en venant s'apposer au niveau de cette portion plane 5, pour former le lot 100. Une vue de face d'un tel récipient 1 est représentée schématiquement sur la figure 2. In this embodiment of the invention, the container 1 has a height of 400mm (millimeters), and comprises a section with a height of 120mm. On this section, the difference between the diameter at the level of the lower limit 18 and the diameter at the level of the upper limit 19 is 3 mm. Thus, this section can be considered as a flat portion 5. In addition, said section, in this example, does not include grooves 8 or other pattern. The strip 2 of paper has a height of 100mm and coats the containers 1, coming to rest at the level of this flat portion 5, to form the batch 100. A front view of such a container 1 is represented schematically on the figure 2.
Dans un autre mode de réalisation, les récipients 1, de section globalement circulaire, sont groupés en quinconce, comme représenté en figure 5, sur une vue de dessus simplifiée. La bande 2 de papier entoure les récipients 1 au niveau d'une portion plane 5, qui se situe vers le bas du récipient 1, dans le sens de la direction principale 15. Dans cet exemple illustratif, la bande 2 présente un revêtement 9 de type vernis sur sa face extérieure. Le récipient 1 est illustré sur une vue de face en figure 4. Ce mode de réalisation, présenté en figure 3, est particulièrement avantageux lorsque les récipients sont de petite dimension. Ce mode de réalisation contribue également au maintien groupé
des récipients 1 qui, lors du soulèvement du lot 100, peuvent avoir tendance à s'écarter au niveau de leur fond, et à augmenter alors la pression exercée sur la bande 2 de maintien. In another embodiment, the containers 1, of generally circular section, are grouped in staggered rows, as shown in FIG. 5, in a simplified top view. The strip 2 of paper surrounds the containers 1 at the level of a flat portion 5, which is located towards the bottom of the container 1, in the direction of the main direction 15. In this illustrative example, the strip 2 has a coating 9 of type varnish on its outer face. The container 1 is illustrated in a front view in FIG. 4. This embodiment, shown in FIG. 3, is particularly advantageous when the containers are small. This embodiment also contributes to the grouped maintenance containers 1 which, when lifting the lot 100, may tend to move apart at their bottom, and then increase the pressure exerted on the band 2 for maintenance.
La répartition des récipients 1 en quinconce présente différents avantages. Notamment, dans le cas de récipients en plastique, de section cylindrique, cette répartition permet de réduire la friction entre la paroi périphérique 7 des récipients 1 au sein du lot 100, lors de la manutention de ce dernier, et permet aussi d'avoir un encombrement légèrement réduit. The staggered distribution of the containers 1 has various advantages. In particular, in the case of plastic containers, of cylindrical section, this distribution makes it possible to reduce the friction between the peripheral wall 7 of the containers 1 within the batch 100, during the handling of the latter, and also makes it possible to have a slightly reduced size.
Il convient de noter que, dans le cas où plusieurs tronçons peuvent être qualifiés de portion plane 5 au sens de l'invention, la bande 2 de papier peut être apposée sur l'une ou l'autre des portions planes 5 des récipients 1. Néanmoins, comme illustré en figure 6, de manière préférentielle, la bande 2 de papier va enrober les récipients 1 au niveau de la portion plane 5 se situant au plus près du centre de gravité 28 desdits récipients 1. La figure 6 présente un lot 100, formé par quatre récipients 1. La bande 2 de papier entoure lesdits récipients 1 au niveau de la portion plane 5 située vers bas d'un récipient 1, afin d'améliorer la stabilité globale du lot 100. Ce mode de réalisation est encore illustré en figure 7, où le centre de gravité 28 d'un tel récipient 1 est représenté schématiquement. On comprend que ce critère de choix de la portion plane est d'autant plus important que les récipients 1 sont hauts, ou contiennent un volume important. En effet, la solidité du lot 100 en sera d'autant plus éprouvée lors du transport ou de la manutention de ce dernier. It should be noted that, in the case where several sections can be qualified as a flat portion 5 within the meaning of the invention, the strip 2 of paper can be affixed to one or the other of the flat portions 5 of the containers 1. Nevertheless, as illustrated in Figure 6, preferably, the strip 2 of paper will coat the containers 1 at the flat portion 5 located closest to the center of gravity 28 of said containers 1. Figure 6 shows a lot 100 , formed by four containers 1. The strip 2 of paper surrounds said containers 1 at the level of the flat portion 5 located towards the bottom of a container 1, in order to improve the overall stability of the batch 100. This embodiment is further illustrated in Figure 7, where the center of gravity 28 of such a container 1 is shown schematically. It is understood that this criterion for choosing the flat portion is all the more important as the containers 1 are high, or contain a large volume. Indeed, the solidity of lot 100 will be all the more tested during transport or handling of the latter.
Dans un autre mode de réalisation, non illustré ici, la bande 2 de papier ne recouvre pas l'intégralité de la surface de la portion plane 5. Dans un tel cas, la bande 2 de papier peut être apposée, à partir et au-dessus de la limite inférieure 18, à partir et au-dessous de la limite supérieure 19, ou à distance respective de l'une et de l'autre. De manière avantageuse, la bande 2 de papier est apposée au plus près du centre de gravité 28 des récipients 1, dès lors que ce dernier se situe entre les deux limites précitées, c'est-à-dire dans la zone de la portion plane 5. In another embodiment, not illustrated here, the strip 2 of paper does not cover the entire surface of the flat portion 5. In such a case, the strip 2 of paper can be affixed, from and above above the lower limit 18, from and below the upper limit 19, or at a respective distance from one and the other. Advantageously, the strip 2 of paper is affixed as close as possible to the center of gravity 28 of the containers 1, since the latter is located between the two aforementioned limits, that is to say in the zone of the flat portion 5.
La figure 8 montre une vue de face d'un récipient 1 particulier. Dans ce mode de réalisation, le récipient 1 présente une portion plane 5 qui revêt la forme d'un cylindre droit, dont l'axe central est aligné sur l'axe central dudit récipient 1. La portion plane 5, dans cet exemple illustratif, est aménagée dans une gorge 29 du corps 3 du récipient 1. Avantageusement, la bande 2 de papier a une hauteur égale ou inférieure à la hauteur de ladite portion plane 5, ce qui lui permet de venir s'apposer contre cette dernière. Cette forme de récipients 1, présentant une gorge d'une hauteur relative suffisante, permet un positionnement particulièrement avantageux de la bande 2 de papier : la gorge permet d'améliorer encore le maintien en position de la bande 2 de papier. En effet, dans cette configuration, la bande 2 de papier ne peut pas glisser ou être déplacée lors de la manutention ou du transport dudit lot 100. Figure 8 shows a front view of a particular container 1. In this embodiment, the container 1 has a flat portion 5 which takes the form of a right cylinder, the central axis of which is aligned with the central axis of said container 1. The flat portion 5, in this illustrative example, is arranged in a groove 29 of the body 3 of the container 1. Advantageously, the strip 2 of paper has a height equal to or less than the height of said flat portion 5, which allows it to come to rest against the latter. This form of container 1, having a groove of sufficient relative height, allows a particularly advantageous positioning of the strip 2 of paper: the groove makes it possible to further improve the holding in position of the strip 2 of paper. Indeed, in this configuration, the strip 2 of paper cannot slip or be moved during the handling or transport of said batch 100.
Dans un autre mode de réalisation, tel qu'illustré en figure 9, le lot 100 comprend deux bandes 20 et 21 de papier. Dans un tel mode de réalisation, la hauteur cumulée des deux bandes 20
et 21 n'excède pas un tiers de la hauteur des récipients 1. Un tel mode de réalisation peut notamment être privilégié pour le conditionnement de récipients 1 d'une grande hauteur, supérieure à 400mm, ou d'un poids conséquent, par exemple supérieur à neuf kilogrammes. In another embodiment, as illustrated in Figure 9, the batch 100 comprises two strips 20 and 21 of paper. In such an embodiment, the cumulative height of the two bands 20 and 21 does not exceed one third of the height of the containers 1. Such an embodiment may in particular be favored for the packaging of containers 1 of great height, greater than 400mm, or of substantial weight, for example greater than to nine kilograms.
De manière avantageuse, le lot 100 peut comprendre un moyen d'adhésion additionnel 10. Dans l'exemple illustré en figure 10, le lot 100 comprend six récipients 1 répartis en matrice rectangulaire, en trois colonnes et deux rangées. La bande 2 de papier forme le lot 100 compact en entourant l'ensemble des récipients 1, au niveau de leur paroi périphérique 7. Advantageously, batch 100 may comprise additional adhesion means 10. In the example illustrated in FIG. 10, batch 100 comprises six containers 1 distributed in a rectangular matrix, in three columns and two rows. The strip 2 of paper forms the compact batch 100 by surrounding all the containers 1, at the level of their peripheral wall 7.
Des moyens d'adhésion additionnels 10, ici des points de colle, sont présents sur ladite paroi périphérique 7 des récipients 1, et plus particulièrement au niveau de la portion plane 5, qui reçoit ladite bande 2 de papier lors de l'enrobage du lot 100. Ces points de colle 10 ont pour avantage d'améliorer la tenue mécanique de la bande 2 de papier. Additional adhesion means 10, here glue dots, are present on said peripheral wall 7 of the containers 1, and more particularly at the level of the flat portion 5, which receives said strip 2 of paper during the coating of the batch 100. These dots of glue 10 have the advantage of improving the mechanical strength of the strip 2 of paper.
Ce mode de réalisation est particulièrement souhaitable lorsque le lot 100 comprend plus que quatre récipients 1. En effet, dans une telle configuration, les récipients 1 situés au milieu de la matrice, c'est-à-dire les récipients 1 de la deuxième colonne, sont entourés par la bande 2 de papier sur une portion moindre par rapport aux récipients 1 situés dans les coins de la matrice, en première ou troisième colonne. La zone de contact 6 est donc plus importante pour un récipient 1 situé dans un angle du lot 100 que pour un récipient 1 situé au centre dudit lot 100, comme représenté sur la figure 10. This embodiment is particularly desirable when the batch 100 comprises more than four containers 1. Indeed, in such a configuration, the containers 1 located in the middle of the matrix, that is to say the containers 1 of the second column , are surrounded by the strip 2 of paper on a smaller portion compared to the containers 1 located in the corners of the matrix, in the first or third column. The contact zone 6 is therefore greater for a container 1 located in a corner of lot 100 than for a container 1 located in the center of said lot 100, as shown in Figure 10.
Dans un mode de réalisation, illustré en figure 11 par une vue de face, le récipient 1 est semi- rigide, présente des cannelures 8 et une forme légèrement évasée au niveau de la portion plane 5. In one embodiment, illustrated in figure 11 by a front view, the container 1 is semi-rigid, has grooves 8 and a slightly flared shape at the flat portion 5.
Sur cette section, d'une hauteur de 100mm, le corps 3 du récipient 1 s'évase, c'est-à-dire que le périmètre du corps 3 de la limite supérieure 19 à la limite inférieure 18 augmente de 6mm. En outre, les cannelures 8 recouvrent environ 25% de la surface de ladite portion plane 5. On this section, with a height of 100mm, the body 3 of the container 1 flares out, that is to say that the perimeter of the body 3 from the upper limit 19 to the lower limit 18 increases by 6mm. In addition, the grooves 8 cover approximately 25% of the surface of said flat portion 5.
Le lot 100 est formé par l'enrobage des récipients 1 groupés en quinconce au moyen d'une bande 2 de papier, apposée au niveau de la portion plane 5. Dans un tel mode de réalisation, la surface de contact 6, entre la paroi périphérique 7 des récipients 1 et la bande 2 de papier est suffisante car est de 75% : en d'autres termes, au niveau de la portion plane 5, la bande 2 de papier est en contact avec 75% de la paroi périphérique 7, les cannelures 8 occupant les autres 25% ne sont pas au contact de la bande 2. L'accolement de la bande 2 de papier est alors suffisant pour maintenir le lot 100 compact. En effet, la bande 2 est en matériau papier, et non en matériau plastique autocollant. Ainsi, elle est susceptible de subir des frictions, des mouvements, et de se déplacer lors de la manutention ou du transport du lot 100. The batch 100 is formed by the coating of the containers 1 grouped in staggered rows by means of a strip 2 of paper, affixed at the level of the flat portion 5. In such an embodiment, the contact surface 6, between the wall peripheral 7 of the containers 1 and the strip 2 of paper is sufficient because is 75%: in other words, at the flat portion 5, the strip 2 of paper is in contact with 75% of the peripheral wall 7, the grooves 8 occupying the other 25% are not in contact with the strip 2. The joining of the strip 2 of paper is then sufficient to keep the batch 100 compact. Indeed, the strip 2 is made of paper material, and not of self-adhesive plastic material. Thus, it is likely to undergo friction, movement, and move during the handling or transport of lot 100.
Par conséquent, la tenue mécanique de la bande 2 de papier est uniquement assurée d'une part par le choix de son positionnement et d'autre part par la tension appliquée par ladite bande 2 de
papier autour du lot 100. Une fois apposée, la bande 2 de papier est dans un état de tension tel qu'il applique une force comprise entre 0.2 et 5kN/m contre la paroi périphérique 7. Consequently, the mechanical strength of the strip 2 of paper is only ensured on the one hand by the choice of its positioning and on the other hand by the tension applied by said strip 2 of paper around lot 100. Once affixed, the strip 2 of paper is in a state of tension such that it applies a force of between 0.2 and 5kN/m against the peripheral wall 7.
Par cet exemple illustratif, on comprend que la présence de reliefs, cannelures 8, ou encore de motifs ne disqualifie pas un tronçon du corps 3 pour constituer la portion plane 5, dans la mesure où, pour ce tronçon, lesdits reliefs, cannelures 8, ceinture, n'ont pas une profondeur et/ou une altitude excédant 4mm (millimètres) dans la direction perpendiculaire à la direction principale 15, sur une hauteur supérieure à 8mm dans la direction principale 15. By this illustrative example, it is understood that the presence of reliefs, grooves 8, or even patterns does not disqualify a section of the body 3 to constitute the flat portion 5, insofar as, for this section, said reliefs, grooves 8, belt, do not have a depth and/or an altitude exceeding 4mm (millimeters) in the direction perpendicular to the main direction 15, over a height greater than 8mm in the main direction 15.
En revanche, la surface de contact 6 entre la bande 2 de papier et la paroi périphérique 7 doit être suffisante, et en particulier au moins égale à 50% de la surface de la portion plane 5, de préférence 70%, au niveau de la zone d'accolement. On the other hand, the contact surface 6 between the strip 2 of paper and the peripheral wall 7 must be sufficient, and in particular at least equal to 50% of the surface of the flat portion 5, preferably 70%, at the level of the joining area.
Par ailleurs, de manière avantageuse, la hauteur de la bande 2 de maintien est appropriée afin de répartir de manière homogène la tension appliquée sur le corps des récipients 1. Cela permet d'éviter une déformation trop importante du corps 3 des récipients 1, en particulier dans un mode de réalisation où les récipients 1 sont PET. Dans ce but, la bande 2 de papier est par exemple d'une hauteur représentant un quart de la hauteur des récipients 1. Un exemple de hauteur appropriée est compris entre 40 et 120mm. Furthermore, advantageously, the height of the retaining strip 2 is appropriate in order to evenly distribute the tension applied to the body of the containers 1. This makes it possible to avoid excessive deformation of the body 3 of the containers 1, in particular in an embodiment where the containers 1 are PET. For this purpose, the strip 2 of paper is for example of a height representing a quarter of the height of the containers 1. An example of a suitable height is between 40 and 120mm.
Un autre avantage qui découle de cette hauteur minimale est le fait que la bande 2 de papier est alors apte à absorber à la fois les chocs liés au transport et la déformation intrinsèque du récipient 1, du fait de son contenu. En effet, il est connu dans le domaine du conditionnement de récipients 1, que ces derniers subissent des déformations au niveau de leur corps 3 : une fois que le récipient est rempli, puis fermé, celui-ci est dit « fini ». Or, au cours de son transport, de son stockage, ledit récipient va subir des légères variations de volume, généralement comprises entre 0.1 et 4% , en augmentation ou en diminution. Le volume des récipients 1 peut ainsi augmenter ou diminuer selon le contenu, par exemple selon que le contenu soit une boisson gazeuse ou non. Ces variations peuvent également être liées aux conditions de stockage, à une hausse de la température par exemple. Ainsi, le volume d'un récipient 1 peut évoluer entre l'opération d'enrobage d'un lot 100 de plusieurs récipients 1 groupés, et sa destination finale, c'est-à-dire sa consommation ou son utilisation. Another advantage which results from this minimum height is the fact that the strip 2 of paper is then capable of absorbing both the shocks associated with transport and the intrinsic deformation of the container 1, due to its content. Indeed, it is known in the field of packaging containers 1, that the latter undergo deformations at the level of their body 3: once the container is filled, then closed, it is said to be "finished". However, during its transport, its storage, said container will undergo slight variations in volume, generally between 0.1 and 4%, increasing or decreasing. The volume of the containers 1 can thus increase or decrease depending on the content, for example depending on whether the content is a carbonated drink or not. These variations can also be linked to storage conditions, to a rise in temperature for example. Thus, the volume of a container 1 can vary between the coating operation of a batch 100 of several grouped containers 1, and its final destination, that is to say its consumption or its use.
La variation du volume d'un récipient 1 sera donc influencée par différents facteurs. Notamment, le dégazage du contenu d'un récipient 1 lors de son stockage va provoquer une variation du volume dudit récipient, et donc de son diamètre. The variation in the volume of a container 1 will therefore be influenced by various factors. In particular, the degassing of the contents of a container 1 during its storage will cause a variation in the volume of said container, and therefore in its diameter.
L'enrobage des récipients 1 groupés doit donc être solide et fiable : il doit permettre de garantir le transport, la manutention des lots 100 quelles que soient les propriétés intrinsèques du récipient 1, les conditions extérieures et quel que soit le contenu desdits récipients 1. The coating of the grouped containers 1 must therefore be solid and reliable: it must make it possible to guarantee the transport, the handling of the batches 100 whatever the intrinsic properties of the container 1, the external conditions and whatever the content of said containers 1.
La bande 2 de papier doit donc être apte à absorber ces variations de volume du corps 3 des récipients 1 tout en maintenant le lot 100 compact. La bande 2 de papier ne doit pas se déchirer sous
l'effet de la variation ou au contraire se relâcher de manière trop importante, ce qui conduirait à un démantèlement du lot 100. Le positionnement optimal de la bande 2 de papier, qui enrobe les récipients 1 groupés au niveau d'une portion plane 5, afin de constituer un lot 100 compact et solide, contribue à éviter ces problèmes. The strip 2 of paper must therefore be capable of absorbing these variations in volume of the body 3 of the containers 1 while keeping the batch 100 compact. Strip 2 of paper must not tear under the effect of the variation or on the contrary to relax too much, which would lead to a dismantling of the batch 100. The optimal positioning of the strip 2 of paper, which coats the containers 1 grouped at the level of a flat portion 5 , in order to constitute a compact and solid batch 100, contributes to avoid these problems.
La figure 12 illustre un mode de réalisation dans lequel le lot 100 comprend un sous-lot 101. Dans cette configuration, six récipients 1 sont regroupés en matrice rectangulaire, sous la forme de trois colonnes et de deux rangées. FIG. 12 illustrates an embodiment in which the batch 100 comprises a sub-batch 101. In this configuration, six containers 1 are grouped together in a rectangular matrix, in the form of three columns and two rows.
Dans cet exemple illustratif, un sous-lot 101 de quatre récipients 1 est formé par les deux dernières colonnes de deux produits chacune, par l'entourage desdits quatre récipients 1 par un bandeau 13 de papier. Le lot 100 est formé par l'enrobage par une bande 2 de papier du sous-lot 101 et des deux récipients 1 restants. In this illustrative example, a sub-batch 101 of four containers 1 is formed by the last two columns of two products each, by surrounding said four containers 1 with a band 13 of paper. Batch 100 is formed by the coating with a strip 2 of paper of sub-batch 101 and the two remaining containers 1.
En outre, éventuellement, des moyens d'adhésion additionnels 10 sont présents sur le bandeau 13 de papier afin d'améliorer sa cohésion avec la bande 2 de papier. De manière optionnelle, des moyens d'adhésion additionnels 10 sont prévus entre les récipients 1 restants et la bande 2 de papier. Furthermore, optionally, additional adhesion means 10 are present on the strip 13 of paper in order to improve its cohesion with the strip 2 of paper. Optionally, additional adhesion means 10 are provided between the remaining containers 1 and the strip 2 of paper.
Dans un autre mode de réalisation, non illustré ici, le lot 100 de six récipients 1 comprend deux sous-lots 101 de deux récipients 1, lesdits sous-lots 101 groupant deux récipients 1 situés en diagonale, c'est-à-dire sur deux rangées différentes et deux colonnes différentes. Autrement dit, les sous-lots 101 sont alors disposés en biais par rapport à la matrice rectangulaire formée par les six récipients 1. In another embodiment, not illustrated here, the batch 100 of six containers 1 comprises two sub-batches 101 of two containers 1, said sub-batches 101 grouping two containers 1 located diagonally, that is to say on two different rows and two different columns. In other words, the sub-lots 101 are then arranged at an angle to the rectangular matrix formed by the six containers 1.
Selon encore un autre mode de réalisation, au moins une paire de sous-lots 101 et 102 positionnés côte à côte sont orientés longitudinalement selon deux rangées, tandis qu'au moins un sous-lot 103 supplémentaire est positionné longitudinalement au moins d'un côté de ladite paire et orienté transversalement, formant alors une colonne. En d'autres termes, deux sous-lots 101 et 102 formant une paire de récipients 1 sont alignés selon la longueur du lot 100 et au moins un sous-lot 103 supplémentaire est positionné transversalement au niveau de l'une et/ou l'autre des extrémités d'un sous-lot 101 ou 102. According to yet another embodiment, at least one pair of sub-batches 101 and 102 positioned side by side are oriented longitudinally along two rows, while at least one additional sub-batch 103 is positioned longitudinally at least on one side of said pair and oriented transversely, thus forming a column. In other words, two sub-lots 101 and 102 forming a pair of containers 1 are aligned along the length of the lot 100 and at least one additional sub-lot 103 is positioned transversely at one and/or the other end of a sub-lot 101 or 102.
Ainsi, on comprend que le lot 100 peut avoir différentes configurations, selon lesquelles tous les récipients 1 d'un même lot 100 sont préalablement groupés en différents sous-lots 101, selon lesquelles seule une partie du nombre total des récipients 1 d'un même lot 100 est préalablement groupée en au moins un sous-lot 101 ou encore selon lesquelles la totalité des récipients 1 d'un même lot 100 sont directement groupés pour former ledit lot 100. Thus, it is understood that the batch 100 can have different configurations, according to which all the containers 1 of the same batch 100 are previously grouped into different sub-batches 101, according to which only part of the total number of containers 1 of the same batch 100 is previously grouped into at least one sub-batch 101 or according to which all the containers 1 of the same batch 100 are directly grouped to form said batch 100.
Cette polyvalence et versatilité quant à la possible différence d'orientation entre certains des sous-lots 101 de récipients 1 au sein d'un même lot 100, permet de diminuer les risques de déchirement de la bande 2 de papier lors de la manutention d'un tel lot 100.
D'autres configurations peuvent être envisagées, en particulier pour des sous-lots 101 regroupant un nombre impair de récipients 1, tout particulièrement regroupant trois récipients 1 et ayant alors une base de forme triangulaire. This versatility and versatility as to the possible difference in orientation between some of the sub-batches 101 of containers 1 within the same batch 100, makes it possible to reduce the risks of tearing of the strip 2 of paper during the handling of such a lot 100. Other configurations can be envisaged, in particular for sub-batches 101 grouping together an odd number of containers 1, more particularly grouping together three containers 1 and then having a triangular-shaped base.
La figure 13 présente une vue en perspective d'un lot 100 comprenant trois sous-lots 101, 102 et 103 en cours d'enrobage. Dans cet exemple illustratif, le bandeau 13 de papier de chacun des sous- lots 101, 102 et 103 entoure les récipients 1 groupés au niveau de la portion plane 5. Figure 13 shows a perspective view of a batch 100 comprising three sub-batches 101, 102 and 103 being coated. In this illustrative example, the strip 13 of paper from each of the sub-lots 101, 102 and 103 surrounds the containers 1 grouped at the flat portion 5.
La bande 2 de papier va enrober les sous-lots 101 pour former le lot 100, en venant s'apposer contre la paroi périphérique 7, au niveau de la même portion plane 5. En d'autres termes, dans ce mode de réalisation, la bande 2 de papier recouvre les bandeaux 13 de papier. The strip 2 of paper will coat the sub-batches 101 to form the batch 100, coming to rest against the peripheral wall 7, at the level of the same flat portion 5. In other words, in this embodiment, the strip 2 of paper covers the bands 13 of paper.
En outre, la bande 2 de papier a une hauteur supérieure à la hauteur du bandeau 13. La bande 2 de papier et les bandeaux 13 de papier présentent une épaisseur similaire, par exemple d'environ 90g/m2, et sont réalisés dans le même matériau papier. In addition, the strip 2 of paper has a height greater than the height of the strip 13. The strip 2 of paper and the strips 13 of paper have a similar thickness, for example approximately 90 g/m2, and are made in the same paper material.
Dans cet exemple illustratif, la bande 2 de papier présente un revêtement 9 sur sa face intérieure, au niveau de son extrémité 16, ledit revêtement étant un revêtement thermoscellable, activable au moyen d'ultrasons. In this illustrative example, the strip 2 of paper has a coating 9 on its inner face, at the level of its end 16, said coating being a heat-sealable coating, which can be activated by means of ultrasound.
Dans ce mode de réalisation, des moyens d'adhésion additionnels 10 sont positionnés entre les différents sous-lots 101, 102 et 103, sur la face extérieure de chacun des bandeaux 13 de papier et entre chaque bandeau 13 et la bande 2. En particulier, les moyens d'adhésion additionnels 10 sont positionnés à des endroits où la zone de contact 6 entre un bandeau 13 et les récipients 1 ou entre la bande 2 et les récipients 1 est la plus faible. Cet exemple illustratif est encore représenté en figure 14, où le lot 100, tel que représenté à la figure 13, est vu depuis le dessus. La cohésion du lot 100 est alors améliorée grâce au double enrobage : chaque récipient 1 est maintenu sur une zone de contact 6 suffisante, que ce soit par la bande 2 de papier et/ou par le bandeau 13 de papier. In this embodiment, additional adhesion means 10 are positioned between the various sub-batches 101, 102 and 103, on the outer face of each of the strips 13 of paper and between each strip 13 and the strip 2. In particular , the additional adhesion means 10 are positioned at places where the contact zone 6 between a strip 13 and the containers 1 or between the strip 2 and the containers 1 is the weakest. This illustrative example is further shown in Figure 14, where lot 100, as shown in Figure 13, is seen from above. The cohesion of the batch 100 is then improved thanks to the double coating: each container 1 is maintained on a sufficient contact zone 6, either by the strip 2 of paper and/or by the strip 13 of paper.
Selon une autre variante, le moyen d'adhésion additionnel 10 peut être appliqué à la fois sur la face extérieure du au moins un bandeau 13 de papier et sur la face intérieure de la bande 2 de papier, quand celle-ci recouvre intégralement le au moins un bandeau 13 de papier, pour former un ruban adhésif de type double face. According to another variant, the additional adhesion means 10 can be applied both to the outer face of the at least one strip 13 of paper and to the inner face of the strip 2 of paper, when the latter completely covers the at least less a strip 13 of paper, to form a double-sided adhesive tape.
Dans un autre mode de réalisation, illustré en figure 15, chacun des récipients 1 présente une étiquette 14. Dans cet exemple illustratif, l'étiquette 14 est apposée sur le corps 3 au niveau d'une portion plane 5. Néanmoins, l'étiquette 14 a une hauteur inférieure à la hauteur de ladite portion plane 5. In another embodiment, illustrated in FIG. 15, each of the containers 1 has a label 14. In this illustrative example, the label 14 is affixed to the body 3 at the level of a flat portion 5. Nevertheless, the label 14 has a height less than the height of said flat portion 5.
Cela permet avantageusement l'ajout de moyens d'adhésion additionnels 10, et en particulier de points de colle. Ainsi, la bande 2 de papier, qui recouvre ici intégralement l'étiquette 14, présentera une tenue mécanique plus importante. Par ailleurs, lors du retrait de la bande 2, c'est-à-dire lors du démantèlement volontaire du lot 100, l'intégrité de l'étiquette 14 sera préservée. En outre, ce mode
de réalisation permet avantageusement de protéger lesdites étiquettes lors du transport ou du stockage des lots 100, ou encore l'impression d'informations spécifiques au lot 100, de type publicitaires ou commerciales, ou encore par exemple un code barre. La bande 2 de papier peut alors présenter un revêtement 9 sur sa face extérieure, à visée esthétique et/ou informative. This advantageously allows the addition of additional adhesion means 10, and in particular glue dots. Thus, the strip 2 of paper, which here completely covers the label 14, will have greater mechanical strength. Moreover, during the removal of the band 2, that is to say during the voluntary dismantling of the batch 100, the integrity of the label 14 will be preserved. In addition, this mode The embodiment advantageously makes it possible to protect said labels during transport or storage of the batches 100, or even the printing of information specific to the batch 100, of the advertising or commercial type, or else for example a bar code. The strip 2 of paper can then have a coating 9 on its outer face, for aesthetic and/or informative purposes.
Par ailleurs, ce revêtement 9, lorsqu'il est à visée technique, peut comprendre un composant spécifique. Les propriétés de ce composant peuvent être activées de différentes manières, par exemple par la chaleur au travers d'une opération de chauffage, thermo-scellage ou thermo-collage, ou bien activable à l'eau, par exemple par humidification notamment aspersion, voire humectation au contact d'une surface humide, ou par tout autre moyen. Furthermore, this coating 9, when it is for technical purposes, can comprise a specific component. The properties of this component can be activated in different ways, for example by heat through a heating, heat-sealing or heat-bonding operation, or can be activated with water, for example by humidification, in particular spraying, or even wetting by contact with a damp surface, or by any other means.
De surcroît, le revêtement 9 peut être une colle ou un revêtement collant appliqué sur l'une et/ou l'autre des faces de la bande 2 de papier et/ou sur le bandeau 13 de papier. In addition, the coating 9 may be an adhesive or a sticky coating applied to one and/or the other of the faces of the strip 2 of paper and/or to the strip 13 of paper.
Dans un mode de réalisation, le revêtement 9 est uniquement appliqué sur les extrémités opposées 16 et 17 de la bande 2 de papier, et est activé par ultrasons lors de l'enrobage du lot 100. In one embodiment, the coating 9 is only applied to the opposite ends 16 and 17 of the strip 2 of paper, and is activated by ultrasound during the coating of the batch 100.
La figure 17 montre un autre mode de réalisation, similaire au mode de réalisation présenté en figure 9. Dans cet exemple, le bandeau 13 de papier entoure chaque sous-lot 101 et 102 au niveau d'une portion plane 5. Figure 17 shows another embodiment, similar to the embodiment shown in Figure 9. In this example, the strip 13 of paper surrounds each sub-batch 101 and 102 at the level of a flat portion 5.
Deux bandes 20 et 21 de papier forment ensuite le lot 100 : une première bande 20 de papier va venir s'apposer sur le bandeau 13 de papier tandis qu'une deuxième bande 21 de papier va venir s'apposer contre la paroi périphérique 7 des récipients 1, au niveau d'une autre portion plane 5. En outre, dans cet exemple illustratif, la hauteur du bandeau 13 est équivalente à la hauteur de la bande 20 de papier. Two strips 20 and 21 of paper then form the lot 100: a first strip 20 of paper will be affixed to the band 13 of paper while a second strip 21 of paper will be affixed against the peripheral wall 7 of the containers 1, at another flat portion 5. In addition, in this illustrative example, the height of the strip 13 is equivalent to the height of the strip 20 of paper.
Ce mode de réalisation est particulièrement avantageux pour des récipients 1 de grande hauteur ou d'un volume important, afin d'améliorer encore la cohésion du lot 100. This embodiment is particularly advantageous for containers 1 of great height or of a large volume, in order to further improve the cohesion of the batch 100.
L'invention concerne également une bande 2 de papier pour former un lot 100 tel que décrit précédemment. The invention also relates to a strip 2 of paper to form a batch 100 as described previously.
La bande 2 est d'une hauteur minimale correspondant à un huitième de la hauteur des récipients 1 formant le lot 100. De manière préférée, la hauteur de la bande 2 correspond à un quart de la hauteur desdits récipients 1. The strip 2 is of a minimum height corresponding to one eighth of the height of the containers 1 forming the batch 100. Preferably, the height of the strip 2 corresponds to a quarter of the height of the said containers 1.
Avantageusement, dans certains modes de réalisation, le grammage du papier constituant la bande est compris entre 50 et 150 grammes par mètre carré (g/m2), de préférence entre 90 et 120g/m2, et encore plus préférablement vaut environ 90g/m2. Advantageously, in certain embodiments, the basis weight of the paper constituting the strip is between 50 and 150 grams per square meter (g/m2), preferably between 90 and 120 g/m2, and even more preferably around 90 g/m2.
En effet, pour que la bande 2 de papier puisse maintenir le lot 100 compact, il faut tout d'abord qu'elle puisse se conformer et être apposée contre la paroi périphérique 7 des récipients 1. Dans un cas où ladite bande 2 serait trop épaisse, par exemple en vue d'améliorer sa solidité, il deviendrait
difficile voire impossible de garantir une zone de contact 6 adéquate entre ladite bande 2 de papier et la portion plane 5. Indeed, in order for the strip 2 of paper to be able to keep the batch 100 compact, it must first of all be able to conform and be affixed against the peripheral wall 7 of the containers 1. In a case where said strip 2 would be too thick, for example in order to improve its solidity, it would become difficult or even impossible to guarantee an adequate contact zone 6 between said strip 2 of paper and the flat portion 5.
En particulier, sur les contours du lot 100, la bande 2 ne serait pas suffisamment souple pour pouvoir être accolée à la paroi périphérique 7 des récipients 1, ce qui pourrait la faire glisser le long du corps 3 desdits récipients 1 sans pouvoir les maintenir ensemble. Cependant, la bande 2 de papier doit également être suffisamment résistante pour ne pas se déchirer dès la première manipulation du lot 100, ou lors de son stockage, par exemple sous l'effet de la variation de volume desdits récipients 1 formant ledit lot, ou même de la tension mécanique nécessaire pour maintenir ensemble les récipients 1 dans le lot 100. In particular, on the contours of lot 100, the strip 2 would not be flexible enough to be able to be attached to the peripheral wall 7 of the containers 1, which could cause it to slide along the body 3 of said containers 1 without being able to hold them together. . However, the strip 2 of paper must also be strong enough not to tear from the first handling of the batch 100, or during its storage, for example under the effect of the variation in volume of said containers 1 forming said batch, or even of the mechanical tension necessary to hold together the containers 1 in lot 100.
Selon une caractéristique additionnelle, la bande 2 de papier présente des propriétés de résistance accrue par rapport à une bande réalisée en papier classique, pour une épaisseur similaire, et en particulier des propriétés d'allongement à la rupture supérieures à 4% et une résistance à la traction supérieure ou égale à 5kN/m (kilonewton par mètre). Ces propriétés peuvent être mesurées perpendiculairement et/ou parallèlement à la direction principale 15 et ces paramètres sont mesurés conformément à la norme ISO 187 et à la norme ISO 1924. According to an additional characteristic, the strip 2 of paper has properties of increased resistance compared to a strip made of conventional paper, for a similar thickness, and in particular properties of elongation at break greater than 4% and resistance to traction greater than or equal to 5kN/m (kilonewtons per meter). These properties can be measured perpendicularly and/or parallel to the main direction 15 and these parameters are measured in accordance with the ISO 187 standard and the ISO 1924 standard.
La bande 2 de papier doit donc être suffisamment flexible et résistante, tout en évitant l'utilisation de plastique dans sa composition. Cela est obtenu en particulier grâce à des propriétés d'allongement à la rupture comprise entre 4 etll%, pour un grammage de la bande 2 de papier compris entre 50 et 150g/m2 (grammes par mètre carré). The strip 2 of paper must therefore be sufficiently flexible and resistant, while avoiding the use of plastic in its composition. This is obtained in particular thanks to properties of elongation at break of between 4 and 11%, for a basis weight of the strip 2 of paper of between 50 and 150 g/m2 (grams per square meter).
L'invention concerne enfin un procédé de conditionnement d'un lot 100 de récipients 1 tel que précédemment décrit. The invention finally relates to a method for packaging a batch 100 of containers 1 as described above.
Un tel procédé de conditionnement est exécuté au sein d'une ligne 23 de conditionnement, dont un exemple d'architecture est représenté sur la figure 18. Such a packaging method is executed within a packaging line 23, an example of architecture of which is shown in FIG. 18.
Lors d'un tel procédé de conditionnement on effectue d'abord un groupage d'au moins deux récipients 1, comme précédemment évoqué. L'étape de groupage consiste à répartir un nombre défini de récipients 1, à savoir au moins deux récipients 1, par exemple depuis un flux unifilaire tel que visible sur la figure 18, ou bien depuis un flux plurifilaire, ou bien encore depuis une accumulation ordonnée ou en vrac de récipients 1, ou autres. During such a packaging process, a grouping of at least two containers 1 is first carried out, as previously mentioned. The grouping step consists in distributing a defined number of receptacles 1, namely at least two receptacles 1, for example from a single-wire stream as seen in FIG. 18, or else from a multi-wire stream, or even from an accumulation ordered or in bulk of containers 1, or others.
Les récipients 1 groupés seront ensuite rassemblés et maintenus ensemble pour former un lot 100. En outre, cette quantité initiale de récipients 1 peut être approvisionnée par une ligne située en amont, comme par exemple une ligne de fabrication desdits récipients 1. The grouped containers 1 will then be assembled and held together to form a batch 100. In addition, this initial quantity of containers 1 can be supplied by a line located upstream, such as for example a production line for said containers 1.
Ledit groupage peut être effectué par un poste 24 de groupage intervenant pour séparer la quantité initiale de récipients 1 et rassembler le nombre de récipients 1 déterminé pour former le lot 100.
Ensuite, le procédé comprend une étape d'enrobage d'au moins deux récipients 1 au moyen de la bande 2 de papier. L'enrobage permet donc de former le lot 100 de récipients 1 pour les maintenir ensemble. Au cours de cette étape, le lot 100 ne circule plus : la bande de convoyage ou la navette sur laquelle il repose est à l'arrêt. Dans certains modes de réalisation, le lot 100 est enrobé alors qu'il circule, à vitesse réduite. Par ailleurs, le lot 100 reste immobile alors que l'alimentation de la bande effectue l'enrobage en tournant autour dudit lot 100. Selon certains modes de réalisation, le lot 100 effectue des rotations dans le sens horaire et/ou anti-horaire par rapport à l'alimentation de la bande 2 de papier. Said grouping can be carried out by a grouping station 24 intervening to separate the initial quantity of containers 1 and bring together the number of containers 1 determined to form the batch 100. Then, the method comprises a step of coating at least two containers 1 by means of the strip 2 of paper. The coating therefore makes it possible to form the batch 100 of containers 1 to hold them together. During this stage, lot 100 no longer circulates: the conveyor belt or the shuttle on which it rests is stopped. In some embodiments, batch 100 is coated as it travels, at reduced speed. Furthermore, the batch 100 remains stationary while the strip feed performs the coating by rotating around said batch 100. According to certain embodiments, the batch 100 performs clockwise and/or anti-clockwise rotations by with respect to the feeding of the strip 2 of paper.
Dans un mode de réalisation où l'on rassemble plus de quatre récipients 1, avantageusement, lors du groupage, on rassemble éventuellement les récipients 1 en au moins un sous-lot 101, chaque sous-lot 101 groupant au moins deux récipients 1. L'étape de groupage permet alors de rassembler le nombre correspondant de récipients 1 de chaque sous-lot 101, à savoir au moins par deux récipients 1, comme visible sur la figure 18. In an embodiment where more than four containers 1 are combined, advantageously, during grouping, the containers 1 are optionally combined into at least one sub-batch 101, each sub-batch 101 grouping together at least two containers 1. The grouping step then makes it possible to gather the corresponding number of containers 1 from each sub-batch 101, namely at least by two containers 1, as shown in Figure 18.
Ensuite, on effectue un entourage de chaque sous-lot 101 par déroulement du au moins un bandeau 13 de papier, qui va s'apposer sur la paroi périphérique 7 des récipients 1, au niveau d'une portion plane 5. Selon un mode de réalisation, on déroule un bandeau 13 au moins jusqu'à recouvrement de ses extrémités. Dans un autre mode de réalisation, plusieurs bandeaux 13 de papier peuvent être déroulés de part et d'autre des récipients 1 de chaque sous-lots 101, jusqu'à venir les raccorder ensemble. Then, each sub-batch 101 is surrounded by unrolling at least one strip 13 of paper, which will be affixed to the peripheral wall 7 of the containers 1, at the level of a flat portion 5. According to a mode of realization, a strip 13 is unrolled at least until its ends are covered. In another embodiment, several strips 13 of paper can be unrolled on either side of the containers 1 of each sub-batch 101, until they are connected together.
Un tel entourage est effectué par un poste 25 d'entourage de la ligne 23 de conditionnement.Such an entourage is performed by a station 25 of entourage of the line 23 of conditioning.
Au cours de cette étape, le ou les sous-lots 101 sont à l'arrêt ou circulent à vitesse réduite. En outre, le ou les sous-lots 101 peuvent être immobiles ou effectuer des rotations dans le sens horaire et/ou anti-horaire par rapport à l'alimentation du bandeau 13 de papier. During this step, the sub-lot(s) 101 are stationary or travel at reduced speed. In addition, the sub-lots 101 can be stationary or perform clockwise and/or anti-clockwise rotations relative to the supply of the strip 13 of paper.
Après, on effectue un enrobage du au moins un sous-lot 101, et éventuellement des récipients 1 restants, par déroulement de ladite au moins une bande 2 de papier jusqu'à recouvrement de ses extrémités 16 et 17. La au moins une bande 2 de papier va venir s'apposer contre la paroi périphérique 7 du récipient 1, au niveau d'une portion plane 5. L'étape d'enrobage permet de venir maintenir les récipients 1 d'un lot 100, éventuellement une fois qu'une partie de ces récipients 1 a préalablement été entourée pour former un ou plusieurs sous-lots 101. Afterwards, the at least one sub-batch 101, and possibly the remaining containers 1, is coated by unrolling said at least one strip 2 of paper until its ends 16 and 17 are covered. The at least one strip 2 of paper will come to rest against the peripheral wall 7 of the container 1, at the level of a flat portion 5. The coating step makes it possible to hold the containers 1 of a batch 100, possibly once a part of these containers 1 has previously been surrounded to form one or more sub-batches 101.
Un tel enrobage est effectué par un poste 26 d'enrobage de la ligne 23 de conditionnement. La figure 18 montre une étape de positionnement des sous-lots 101 transversalement côte à côte en entrée du poste 26 d'enrobage. Such coating is carried out by a coating station 26 of the line 23 of packaging. Figure 18 shows a step of positioning the sub-batches 101 transversely side by side at the entrance to the station 26 of coating.
Lors de l'entourage d'un sous-lot 101 ou de l'enrobage d'un lot 100, les postes 25 et 26 correspondants peuvent être paramétrés afin d'indiquer quelle doit être la force appliquée par le bandeau 13 de papier et/ou par la bande 2 de papier. En particulier, la force appliquée par le
bandeau 13 de papier et/ou par la bande 2 de papier doit être comprise entre 0.2 et 5kN/m (kilonewton par mètre), de préférence 0.2 à lkN/m au niveau de la portion plane 5. Par exemple, pour une bande 2 de papier d'une hauteur de 50mm, la force appliquée est comprise entre 10 et 50N. Cette force appliquée contribue au maintien ensemble des récipients 1 sous la forme d'un lot compact 100. When wrapping a sub-batch 101 or wrapping a batch 100, the corresponding items 25 and 26 can be configured to indicate what force must be applied by the strip 13 of paper and/or or by strip 2 of paper. In particular, the force applied by the strip 13 of paper and/or strip 2 of paper must be between 0.2 and 5 kN/m (kilonewtons per meter), preferably 0.2 to lkN/m at the flat portion 5. For example, for a strip 2 of paper with a height of 50mm, the force applied is between 10 and 50N. This applied force helps hold the containers 1 together as a compact pack 100.
Dans d'autres modes de réalisation, chaque sous-lot 101 est entouré par un poste 25 distinct : il y a donc plusieurs postes 25 sur une même ligne de conditionnement 23. In other embodiments, each sub-batch 101 is surrounded by a separate station 25: there are therefore several stations 25 on the same packaging line 23.
Dans le cas où deux bandes 20 et 21 enrobent le lot 100, la ligne de conditionnement 23 comprend deux postes d'enrobage 26. In the case where two strips 20 and 21 coat batch 100, packaging line 23 includes two coating stations 26.
Dans un autre mode de réalisation, non représenté ici, un même poste 25 réalise l'entourage d'au moins un sous-lot 101 puis l'enrobage du lot 100. Ce mode de réalisation est particulièrement avantageux car il permet d'augmenter la cadence de la ligne de conditionnement 23. Cela a un également un impact écologique car permet de réduire la consommation d'énergie de ladite ligne. In another embodiment, not represented here, the same station 25 carries out the entourage of at least one sub-batch 101 then the coating of the batch 100. This embodiment is particularly advantageous because it makes it possible to increase the rate of the packaging line 23. This also has an ecological impact because it makes it possible to reduce the energy consumption of said line.
Comme illustré en figure 18, lorsqu'on souhaite ajouter un moyen de préhension au lot 100, le procédé comprend une étape supplémentaire. As illustrated in FIG. 18, when it is desired to add a gripping means to batch 100, the method comprises an additional step.
Pour ce faire, selon un mode de réalisation, après entourage d'un sous-lot 101, on fixe une poignée 11 sous forme d'au moins une sangle 12 en recouvrement partiel d'au moins un bandeau 13 de papier d'un des sous-lots 101. Ensuite, au moment de l'enrobage, on recouvre ladite sangle 12 avec la bande 2 de papier. To do this, according to one embodiment, after surrounding a sub-batch 101, a handle 11 is fixed in the form of at least one strap 12 partially overlapping at least one band 13 of paper from one of the sub-batches 101. Then, at the time of coating, said strap 12 is covered with strip 2 of paper.
Une telle fixation de la poignée 11 est effectuée par un poste 27 de fixation de la ligne 23 de conditionnement. Un tel poste 27 de fixation peut intervenir entre le poste 25 d'entourage et le poste 26 d'enrobage, directement le long du flux de sous-lots 101, ou bien en prélevant un sous-lot 101 parmi ledit flux puis en le réinsérant avant enrobage dans le flux de sous-lots 101, à une position déterminée, par exemple au centre du lot 100 à former, comme visible sur l'exemple de la figure 16. Such fixing of the handle 11 is performed by a station 27 for fixing the line 23 of packaging. Such a fixing station 27 can intervene between the surrounding station 25 and the encapsulating station 26, directly along the stream of sub-batches 101, or else by taking a sub-batch 101 from said stream and then reinserting it before coating in the flow of sub-batches 101, at a determined position, for example in the center of the batch 100 to be formed, as seen in the example of Figure 16.
Le procédé peut comporter une étape supplémentaire : avant enrobage d'un lot 100, on applique en face intérieure de chaque bande 2 de papier, un moyen d'adhésion additionnel 10, situé au niveau de la zone de contact 6 de chaque récipient 1 du lot 100. The method may include an additional step: before coating a batch 100, an additional adhesion means 10 is applied to the inside face of each strip 2 of paper, located at the level of the contact zone 6 of each container 1 of the batch 100.
Selon différentes variantes, on applique en face extérieure d'un bandeau 13 d'un sous-lot 101, un moyen d'adhésion additionnel 10, au niveau de zones d'accolement entre deux sous-lots 101, ou entre un sous-lot 101 et un ou plusieurs autres récipients 1. According to different variants, an additional adhesion means 10 is applied to the outer face of a strip 13 of a sub-batch 101, at the level of adjoining zones between two sub-batches 101, or between a sub-batch 101 and one or more other containers 1.
Ainsi, au travers du lot 100 tel que précédemment décrit, ainsi que de son procédé de conditionnement, l'invention permet d'obtenir une excellente tenue et un maintien solidaire d'au moins deux récipients 1 groupés ensemble, au moyen d'une bande 2 de papier, apposée sur une portion plane desdits récipients, ce qui garantit un conditionnement respectueux de l'environnement. Thus, through the lot 100 as described above, as well as its packaging method, the invention makes it possible to obtain excellent hold and a solid hold of at least two containers 1 grouped together, by means of a band 2 of paper, affixed to a flat portion of said containers, which guarantees packaging that respects the environment.
Dans des modes de réalisation possibles, la bande 2 de papier est en papier présentant un grammage compris entre 50 et 150g/m2 (gramme par mètre carré). Cela permet à la fois d'utiliser peu
de matières premières pour la réalisation de la bande 2, et de générer peu de déchets. En outre, un tel grammage permet à la bande 2 de s'adapter à la forme générale des récipients 1. En particulier, la bande 2 va pouvoir se courber, se conformer au contour extérieur du lot 100. Une épaisseur trop importante de la bande 2 entraînerait un manque de souplesse de cette dernière, qui ne pourrait alors pas épouser la forme des récipients 1 formant le lot 100. Or, pour que le lot 100 ne se disloque pas, il est nécessaire d'avoir une zone de contact adéquate entre la bande 2 en papier et chacun des récipients 1 dudit lot 100. Un tel grammage permet de combiner une bonne prise de forme ainsi qu'une bonne tenue mécanique de la bande 2 elle-même. In possible embodiments, the strip 2 of paper is made of paper having a weight of between 50 and 150 g/m2 (gram per square meter). This allows both to use little of raw materials for the production of strip 2, and to generate little waste. In addition, such a weight allows the strip 2 to adapt to the general shape of the containers 1. In particular, the strip 2 will be able to bend, to conform to the outer contour of the batch 100. Too great a thickness of the strip 2 would lead to a lack of flexibility of the latter, which could then not match the shape of the containers 1 forming the batch 100. However, so that the batch 100 does not break up, it is necessary to have an adequate contact zone between the strip 2 of paper and each of the containers 1 of said batch 100. Such a weight makes it possible to combine good shape retention as well as good mechanical strength of the strip 2 itself.
Dans des modes de réalisation possibles, les récipients 1 reposent sur leur fond dans une orientation normale. En d'autres termes, les récipients 1 qui forment le lot 100 sont en position verticale. Cela permet à un utilisateur d'avoir une utilisation classique et adaptée. In possible embodiments, the containers 1 rest on their bottom in a normal orientation. In other words, the containers 1 which form the batch 100 are in a vertical position. This allows a user to have a classic and adapted use.
Dans certains modes de réalisation, la bande 2 en papier a une hauteur d'au moins cinquante pour cent de la hauteur H de chacun des récipients 1 le long de la direction principale 15. In some embodiments, the paper strip 2 has a height of at least fifty percent of the height H of each of the containers 1 along the main direction 15.
L'invention, de par l'apposition d'une bande 2 en papier contre la portion plane d'un récipient 1, permet à la fois de garantir une grande solidité du lot, mais aussi de diminuer de manière considérable le volume des déchets. The invention, by affixing a strip 2 of paper against the flat portion of a container 1, makes it possible both to guarantee great solidity of the batch, but also to considerably reduce the volume of waste.
L'invention concerne encore une installation de conditionnement en lot 100 de récipients 1 mettant en oeuvre le procédé de l'invention, ladite installation produisant ainsi des lots 100 tels que décrits ici dans les différentes variantes possibles. The invention also relates to an installation 100 for packaging containers 1 in batches implementing the method of the invention, said installation thus producing batches 100 as described here in the different possible variants.
L'installation de conditionnement réalise donc des lots 100 d'au moins deux récipients 1 selon l'invention. The packaging installation therefore produces batches 100 of at least two containers 1 according to the invention.
L'installation de conditionnement en lot est caractérisée en ce qu'elle utilise une bande 2 en papier. The batch packaging installation is characterized in that it uses a strip 2 of paper.
L'installation de conditionnement comprend notamment un poste de groupage 24 d'au moins deux récipients 1, au moins un poste d'enrobage 26 d'au moins une bande 2 en papier autour de l'ensemble qu'ils forment. Avantageusement, l'installation comprend un poste d'entourage 25 pour la création de sous-lots 101. The packaging installation comprises in particular a grouping station 24 of at least two containers 1, at least one coating station 26 of at least one strip 2 of paper around the assembly that they form. Advantageously, the installation includes an entourage station 25 for creating sub-lots 101.
Selon une caractéristique possible, le poste d'entourage 25 et/ou le poste d'enrobage 26 comprend un module de scellement pour refermer ladite bande 2 autour du lot 100 en liant ses extrémités opposées 16 et 17 pour la fermer sur elle-même. Ce module de scellement peut être un module d'activation d'adhésif par l'eau, ou encore par la chaleur. Selon une caractéristique additionnelle, le module de scellement est un module de soudure par ultrasons. According to one possible characteristic, the wrapping station 25 and/or the enrobing station 26 comprises a sealing module for closing said strip 2 around the lot 100 by linking its opposite ends 16 and 17 to close it on itself. This sealing module can be an adhesive activation module by water, or else by heat. According to an additional characteristic, the sealing module is an ultrasonic welding module.
Selon une caractéristique possible, le module de scellement de la bande est un module séparé des postes 25 et 26.
Selon une variante possible, l'installation comprend au moins un poste de fixation 27 d'une sangle 12 sous forme de poignée 11 autour du lot 100. According to a possible characteristic, the tape sealing module is a separate module from stations 25 and 26. According to a possible variant, the installation comprises at least one fixing station 27 of a strap 12 in the form of a handle 11 around the lot 100.
Avantageusement, le poste de fixation 27 se situe en aval du module d'apposition de la bande 2 en papier. Dans des modes de réalisation, le poste d'entourage 25 et le poste d'enrobage 26 d'au moins une bande 2 en papier forment un seul et même poste. Advantageously, the fixing station 27 is located downstream of the module for affixing the strip 2 of paper. In some embodiments, the surrounding station 25 and the encapsulating station 26 of at least one strip 2 of paper form a single and same station.
Selon une variante possible, le poste d'enrobage 26 d'au moins une bande 2 en papier et le poste de fixation 27 forment un seul et même poste. En d'autres termes, le poste d'enrobage 26 est capable de déposer une sangle 12 sous forme de poignée 11 autour du lot 100. Bien que la description ci-dessus se base sur des modes de réalisation particuliers, elle n'est nullement limitative de la portée de l'invention, et des modifications peuvent être apportées, notamment par substitution d'équivalents techniques ou par combinaison différente de tout ou partie des caractéristiques développées ci-dessus.
According to a possible variant, the station 26 for encapsulating at least one strip 2 of paper and the fixing station 27 form one and the same station. In other words, the enrobing station 26 is capable of depositing a strap 12 in the form of a handle 11 around the lot 100. Although the description above is based on particular embodiments, it is by no means limitation of the scope of the invention, and modifications may be made, in particular by substitution of technical equivalents or by different combination of all or part of the characteristics developed above.
