Definitions

  • the present invention concerns a disposable package. More particularly, it is directed to a disposable package that has a very light weight.
  • packaging solutions described above require different separate steps for filling and closing, and therefore they are incompatible with polluted - dusty for instance - environments, without the use of specific additional and costly equipments for ensuring substantially aseptic filling and closing operations.
  • a flexible pouch-like disposable package made from a thermoplastic film having a thickness of less than 100 microns, comprising a package body, characterized in that the package body comprises at least two walls, one of said walls comprising a filling area, which is optionally a filling opening, for filling said package with a flowable product, said walls being disposed adjacent to one another so that after filling, said walls can be sealed together by a seal disposed around said opening so that the package is hermetically closed.
  • the package With such a package, it is possible to easily and rapidly close the opened filling area - or the filling opening - after the filling step, which allows high manufacturing rates. Moreover, the package is in one piece, and all of its walls - even when it is closed - are sufficiently thin to ensure that very little packaging material is used, so that the ecological footprint of a package according to the present invention is very tiny.
  • the film has a thickness of less than 80 microns, preferably less than 50 microns.
  • thermoplastic film be made from a biodegradable, or oxo-biodegradable, material such that said package is entirely destroyed within a period of less than 700 days, preferably less than 200 days, more preferably less than 90 days when placed in favourable biodegradability conditions.
  • said biodegradable thermoplastic film is made from a material selected in the list of: polyhydroxyalkanoates (PHA) such as for instance poly-3-hydroxybutyrate (P3HB), poly-4-hydroxybutyrate (P4HB), polyhydroxyvalerate (PHV), polyhydroxyhexanoate (PHH), polyhydroxyoctanoate (PHO) and their copolymers, zein-based bioplastic polymers, starch-based resins, polylactic acid based resins, hemp-based resins, cellulose-based resins, or a combination thereof.
  • PHA polyhydroxyalkanoates
  • P3HB poly-3-hydroxybutyrate
  • P4HB poly-4-hydroxybutyrate
  • PV polyhydroxyvalerate
  • PH polyhydroxyhexanoate
  • PHO polyhydroxyoctanoate
  • zein-based bioplastic polymers starch-based resins, polylactic acid based resins, hemp-based resins, cellulose-based resins, or a combination thereof.
  • the package according to the invention once it is filled and closed, can be opened - for instance by a consumer - by cutting, punching, tearing, piercing or a combination thereof.
  • the filling opening of the package is a hole that is punched out from the wall of the package body.
  • the inner diameter of the filling opening substantially corresponds to the outer diameter of the filling needle that is used for filling, and said inner diameter is comprised between 1 and 15 mm, preferably comprised between 3 and 10 mm.
  • the fact that the inner diameter of the package opening corresponds substantially to the diameter of the filling needle is made possible by the fact that the walls of the package are flexible and very thin, and have therefore an elasticity that prevents the filling needle to be blocked into the said opening when said needle is introduced into the package for the filling and then removed therefrom. Furthermore, it ensures that almost no dust, smoke, or other similar kind of undesirable particles can enter the package before, during, or after the filling, even if these operations are performed in a polluted (for instance dusty) environment.
  • the package is a premade film pouch manufactured and stored as a continuous roll, so that two adjacent pouches in the roll are linked in a detachable manner by a precut seam.
  • the package of the invention can comprise several separate chambers inside its body, so that when said package is filled and closed, its base comprises a substantially flat surface.
  • the package according to the invention is particularly meant - due to the clean conditions of filling and closing it offers - to be filled with a flowable product that is selected from the list of: gases, powders, granulates, gels, creams, liquids or a combination thereof, and is preferably an edible product.
  • the present invention is further related to a packing process for packing a flowable material into a package according to any of the preceding claims, characterized in that it comprises the steps of, in order:
  • the package be a premade film pouch manufactured and stored as a continuous roll, so that two adjacent pouches in the roll are linked in a detachable manner by a precut seam.
  • the filling means can comprise weighing means, or a volumetric filling system, or a flow meter and/or an intermediate tank for the control of the filled volume of beverage into the package.
  • the present invention is meant to be used for instance with a filling and closing system contained in a water fountain for in home usage.
  • a filling and closing system contained in a water fountain for in home usage.
  • the present invention shall be also used in offices.
  • the overall volume of said fountain is less than 1 m 3 , preferably less than 0.5 m 3 , even more preferably less than 0.2 m 3 , so that said fountain can fit in small spaces like a kitchen or an office. Therefore, the package according to the present invention can have various sizes, but is adapted for small volumes (less than 1litre of content), and is adapted to be filled and closed in a filling and closing system having a reduced size.
  • the present invention is directed to a one-piece flexible pouch-like disposable package 1 made from a thermoplastic film having a thickness of about 70 microns, comprising a package body and a filling area 2.
  • the filling area is a filling opening (2).
  • the filling area could stay closed until the package is filled, for instance by a filling needle that would pierce the package wall in the region of the filling area, and then said area would be closed again by performing a seal as will be described hereafter in detail.
  • the package body comprises at least two walls, one of said walls comprising the filling opening 2 for filling said package 1 with a flowable product 3, said walls being disposed adjacent to one another so that after filling, said walls can be sealed together by a seal 4 disposed around said opening 2 so that the package 1 is hermetically closed.
  • thermoplastic film that is used is a biodegradable material such that at least 90% of said package is destroyed within a period of less than 90 days when placed in favourable biodegradability conditions, according to European standard EN 13432.
  • biodegradability it is meant that 4 essential elements are present in the environment to allow a biodegradation to occur: sufficiently high temperature, presence of micro-organisms, sufficiently high level of oxygen, sufficiently high level of humidity.
  • said biodegradable thermoplastic film is made from a material selected in the list of: polyhydroxyalkanoates (PHA) such as for instance poly-3-hydroxybutyrate (P3HB), poly-4-hydroxybutyrate (P4HB), polyhydroxyvalerate (PHV), polyhydroxyhexanoate (PHH), polyhydroxyoctanoate (PHO) and their copolymers, zein-based bioplastic polymers, starch-based resins, polylactic acid based resins, hemp-based resins, cellulose-based resins, or a combination thereof.
  • PHA polyhydroxyalkanoates
  • P3HB poly-3-hydroxybutyrate
  • P4HB poly-4-hydroxybutyrate
  • PV polyhydroxyvalerate
  • PH polyhydroxyhexanoate
  • PHO polyhydroxyoctanoate
  • zein-based bioplastic polymers starch-based resins, polylactic acid based resins, hemp-based resins, cellulose-based resins, or a combination thereof.
  • the package 1 according to the invention once it is filled and closed, can be opened - for instance by a consumer - by cutting, punching, tearing, piercing or a combination thereof.
  • the filling opening 2 of the package 1 is a hole that is punched out from the wall of the package body at the time the package is manufactured, as will be described in more details hereafter.
  • the inner diameter of the filling opening 2 substantially corresponds to the outer diameter of a filling needle 5 that is used for filling.
  • the inner diameter of the filling opening 2 is 7 mm.
  • the package according to the invention is made as part of a roll of premade pouches 1, as illustrated for instance in figures 1 to 7 .
  • the packages according to the invention are specifically adapted to be filled and closed in a continuous filling and sealing system as explained hereafter.
  • the pouches 1 described above are manufactured as a roll of pouches, with a continuous process illustrated in figures 2A and 2B , wherein figure 2B is a 90°side view of the figure 2A , so as to show how the film is folded during the forming operation.
  • the roll of pouches is formed out of a thermoplastic film that is rolled and sealed longitudinally into a tube. Two pairs of rolls 6 that are disposed spaced apart from one another fold the film, and the filling openings 2 are cut by punching at regular intervals along the roll. Then, another pair of rolls 7 folds the tube of film at a 90° angle relative to the longitudinal axis of said tube, and two pairs of sealing jaws 8 seal the pouch at its upper 9 and lower 10 extremities, as illustrated in figures 2A and 2B . As can be seen in figure 2B , the upper seal 9 has a specific shape which allows positioning this upper seal 9 very close to the pouch opening 2.
  • the sealing jaws 8 create a seal to close the upper and lower edges of a pouch, they create transversal pre-cut seam lines 11 respectively above and below the upper 9 and lower 10 seals of the pouch 1, as illustrated for instance in figures 8 , 12 or 13 .
  • the pre-cuts 11 are made by cutting tools - not shown in the drawings - that are integrated in the sealing jaws 8.
  • the roll of pouches 1 is meant to be mounted into a filling and closing (also called “sealing") system, such that the free end of pouches runs through filling means and sealing means that ensure respectively that water is filled into each pouch 1, and then said filled pouch 1 is sealed.
  • a filling and closing also called “sealing”
  • the filling means comprises a pipe 12 that conveys water from a water source.
  • This pipe 12 is linked to a filling pump - not illustrated in the drawing - coupled to an electronic management system - not illustrated in the drawing - that synchronises the movements of the roll of pouches together with the filling pump and the sealing means.
  • the pipe 12 is linked to a filling needle 14 that is movable in a back-and-forth movement relative to the pouch 1 that is being filled, as can be seen in detail in figures 6 to 11 .
  • the needle 14 is moved with a piston-like system 15 that can be seen in figure 6 .
  • each roll 16 is equipped with rubber surfaces 17 that have a gripping effect onto the surface of the pouch 1, so that the pouch does not slip away during the filling operation.
  • the rolls 16 comprise cooperating grooves 13 that define a passage through which the filling needle 14 can move to fill the package 1, as can be seen in figures 9 , 10 and 11 .
  • the pouch 1 comprises a rounded opening 2 through which the filling needle 5 of the filling system can penetrate before the filling operation starts. Once the pouch is filled, the needle 5 is removed from the pouch, and the latter is sealed be the sealing means.
  • the two rolls 16 that hold the pouch 1 during the filling operation both comprise grooves, that are positioned in vis-à-vis one relative to the other, so that the two cooperating grooves define a channel which has a diameter superior or equal to that of the filling needle 5, so that said needle can move back and forth in between the rolls 16 during the filling operation.
  • Figure 8 shows a roll of pouches that is disposed into the filling means and sealing means.
  • One pouch 1 a is already filled and is being sealed, and the pouch 1 b above in the roll of pouches is being filled.
  • the sealing means comprise a pair of sealing jaws 18 that are movable in a back and forth reciprocating movement by actuating means - not shown in the drawing - for instance a pneumatic piston, or an electric motor, similarly to sealing jaw systems commonly known to those skilled in the art.
  • the roll of pouches is unrolled, so that the upper edge 9 of the filled pouch is disposed between the sealing jaws 18.
  • the unrolling movement is then stopped and the sealing jaws 18 are moved towards each other as illustrated with arrows in figure 5 so as to seal the opening 2 of the pouch 1, and then backwards so as to release the pouch that is now filled and sealed.
  • the unrolling operations then starts again so that the pouch that is filled and sealed can be directed to the cutting means 19 - shown in figures 6 and 7 - to be detached from the roll of pouches, and fall into the dispensing drawer 20 as shown in figure 7 .
  • the cutting means 19 can be a cutting blade that is moved back and forth with an electric motor.
  • the roll of pouches, the filling means and the sealing and cutting means can be enclosed into a casing (or otherwise called “cartridge") 21.
  • the front part of the casing 21 can be equipped with a window 22 for a consumer to watch the filling, sealing and cutting operations, as illustrated in figure 7 .
  • the casing 21 comprises a backdoor 23 to access the interior of the said casing and replace the roll of pouches when necessary.
  • the premade weld seam length represents at least 70% of the final weld seam length, in other words the area that is not seamed when the pouch is still in the roll of pouches, is less than 30% of the seam length that is necessary for having an entirely closed package.
  • Each package used to pack water in the field of the present invention is preferably shaped such that the material constitutive of the package body in one cross-section, extends beyond the boundaries of the filling opening. This ensures that the dispensing opening of the package is somehow protected by the boundaries of the package, and is therefore more mechanically resistant.
  • the packages 1 are realized as premade preferably decorated/printed packages.
  • the film for making said pouches 1 is preferably pre-printed before being formed into a roll of pouches as will be described hereafter.
  • Figure 12 illustrates a roll of pouches 1 that is obtained with a process as described above.
  • a detachable - or tearable - pre-cut line 11 that is transversally disposed along the width of the roll.
  • Figures 12 to 15 show two consecutive pouches 1 in the roll of pouches.
  • the lower pouch is already filled, and its opening 2 is sealed. It is ready to be detached from the rest of the roll along the pre-cut line 11.
  • each pouch opening 2 alone remains unsealed, until the filling step is completed. After the filling step, this opening 2 is sealed as well by a closing seal 24 that is rounded in shape to adapt to the opening shape.
  • the filled pouch 1 is therefore completely and hermetically closed. It is to be noted that the filling and sealing step are done in aseptic conditions.
  • the shape of each pouch is generally parallelepipedic, for instance square, as illustrated in figure 12 .
  • each pouch 1 is generally square or rectangular.
  • Each pouch 1 is formed from a tubular film as described hereinabove, with upper and lower edges which are sealed transversally to close the pouch.
  • an L-shaped seal 25 is created that is generally parallel and adjacent to one side of the pouch. This L-shaped seal 25 is not sealed across its entire surface as can be seen in figure 13 , but its central area 26 is not sealed and comprises a pre-cut line 27, disposed so that the portion of the pouch 1 located between the L-shaped seal 25 and the adjacent side wall can be detached to form a detachable spout 28 as illustrated in figure 14 .
  • the free end 29 of the detachable spout (once it is detached from the rest of the pouch 1) can be cut by the consumer before dispensing.
  • the dispensing spout 28 creates a convenient way of dispensing the pouch contents, without requiring a complex shape of the pouch 1.
  • FIG. 15 , 16 and 17 is illustrated yet another possible embodiment of a pouch to be used in an apparatus according to the present invention.
  • each pouch 1 in the roll is generally as formerly described above, i.e. made from a tubular film which is sealed transversally to create the pouch.
  • the pouch 1 comprises an additional, generally U-shaped, seal 30 that comprises in its surface a pre-cut - not shown in the drawing -.
  • This seal 30 surrounds the pouch opening 2 and is made after the pouch 1 is filled.
  • the seal 30 is in fact shaped and disposed so that the opening 2 is completely enclosed between the U-shaped seal 30 and the upper seal of the pouch 9. In this way, when the seal 30 is made, the pouch is completely closed, as can be seen in figure 15 .
  • the pouch When the portion of the pouch that is enclosed in the U-shaped seal 30 is detached, the pouch remains closed, while an opening 31 is created at the same time, as illustrated in figure 16 , so that a consumer can insert the hand to hold and carry the pouch as illustrated in figure 17 .
