Definitions

  • the present invention relates to a paper-based or paperboard-based container and a method for producing such a container.
  • a pourable food product e.g. a liquid, e.g. dairy products, such as milk or yoghurt, or juices.
  • the blank is typically produced from a laminate packaging material, which typically comprises a multi-ply paperboard sheet on which is laminated one or a plurality of barrier layers for holding the food product and/or prevent migration of air and flavours through the paperboard.
  • a barrier layer may typically comprise a polyethylene or an aluminium layer.
  • a method of producing the blank from the laminate packaging material typically comprises the steps of cutting the laminate packaging material to a predefined shape, and a method of producing the container from the blank typically comprises the step of folding the blank along predefined folding lines to produce the container.
  • the blank may be provided with crease lines in the laminate packaging material to aid folding of the blank along the folding lines.
  • a crease line, or crease may be defined as an embossed or impressed depression on one side of the laminate packaging material with a corresponding raised ridge or welt, also referred to as the bead, on the other side forming a line along which the laminate packaging material is structurally weakened and along which the laminate packaging material will bend or fold when pressure is applied.
  • the container may be provided with a closure allowing a consumer to open the container to access the food product
  • US6182887B1 shows a container having an extended top panel produced by sealing the top panel and a rear wall of the container to one another at a sealing region that is coextensive with a top fin. Consequently, the top fin extends from the top panel in the plane of the rear wall, thus making essentially the whole top panel available for usage, e.g. positioning of a closure.
  • the extending top-fin may still restrict access to the top panel.
  • a top-fin extending from the top panel in the plane of the rear wall may make it difficult for a consumer to drink directly from the container.
  • the present disclosure provides a paper-based or paperboard-based container for holding a pourable food product, comprising:
  • the top-fin, or top sealing region is folded onto the wall portion comprising the longitudinal sealing band, i.e. the longitudinal seam running from the bottom to the top of the container.
  • sealing structures may comprise permanently sealing structures such as welded, glued or otherwise permanently joined seams where panels of the laminate sheet material are permanently joined to each other. This allows the top panel to be utilised in an efficient manner.
  • a top closure can be positioned anywhere on the top panel since there will be no sealing structure to consider. Also, folding the top sealing region down onto the side wall portion comprising the longitudinal sealing band and attaching the sealing region thereto will give a consumer unrestricted access to the closure for accessing or dispensing the food product in an easy manner.
  • the top sealing region may be planar or substantially planar and arranged parallel or substantially parallel to said at least one of the wall sections comprising the longitudinal sealing band.
  • the top panel and the top sealing region may share a common border forming a top edge of the container.
  • the top edge may be rectilinear or substantially rectilinear and arranged parallel or substantially parallel to the bottom portion.
  • a closure may be arranged in the top panel for dispensing and/or accessing the food product.
  • the closure in contrast to the above-mentioned sealing structures, including the top sealing region and the longitudinal sealing band, is not arranged to permanently seal the container but may be opened by a consumer to allow the consumer to dispense or access the food product.
  • the closure may comprise an opening being arranged adjacent said top edge.
  • the opening may be arranged at an orthogonal distance of between 1 mm to 10 mm from the top edge.
  • the top panel may be planar or substantially planar.
  • the wall section or wall sections comprising the longitudinal sealing band may also be planar or substantially planar and the top panel may form an angle to said wall section or wall sections that is of any one of: within the range of 10 degrees to 90 degrees; within the range of 30 degrees to 80 degrees, within the range of 45 degrees to 75 degrees; and 60 degrees.
  • the top sealing region may comprise a plurality of sealed sealing band panels, all of which may be arranged parallel or substantially parallel and/or coplanar or substantially coplanar in the container.
  • the sealing band panels may comprise a central sealing band panel extending over the wall section or the wall sections comprising the longitudinal sealing band and having a longitudinal extent being any one of: at least 15 mm, at least 20 mm and at least 30 mm.
  • the present disclosure provides a paper-based or paperboard-based sleeve for producing the container according to the first example aspect.
  • the present disclosure provides a paper-based or paperboard-based blank for producing the sleeve according to the second example aspect.
  • the blank may be mirror-symmetric about a longitudinal central axis of the blank.
  • the blank may comprise first and second rectilinear or substantially rectilinear and parallel or substantially parallel boundary edges forming lateral or longitudinal boundary edges of the blank.
  • the blank may also a third rectilinear or substantially rectilinear boundary edge extending orthogonally or substantially orthogonally between the latera boundary edges and forming a bottom boundary edge of the blank.
  • the blank may comprise a fourth, non-rectilinear boundary edge extending between the lateral boundary edges and forming a top boundary edge of the blank.
  • the top boundary edge may be mirror-symmetric about a longitudinal central axis of the blank.
  • the top boundary edge may comprise a plurality of individually rectilinear top boundary edge sections.
  • the present disclosure provides a method of producing a paper-based or paperboard-based container for holding a pourable food product comprising the steps of:
  • the method may comprise a step of providing a top panel of the container free from sealing structures.
  • sealing structures may comprise permanently sealing structures such as welded, glued or otherwise permanently joined seams where panels of the laminate sheet material are permanently joined to each other.
  • the method may comprise arranging the top sealing region planar or substantially planar and parallel or substantially parallel to said at least one of the wall sections comprising the longitudinal sealing band.
  • the method may comprise arranging the top panel and the top sealing region such that they share a common border forming a top edge of the container.
  • the method may comprise a step of arranging the top edge rectilinear or substantially rectilinear and the step of arranging the top edge parallel or substantially parallel to a planar or substantially planar bottom portion of the container.
  • the method may comprise a step of arranging a closure for dispensing or accessing the food product in the top panel of the container.
  • the method may comprise a step of arranging an opening of the closure adjacent said top edge forming a border between the top panel and the top sealing region.
  • the method may comprise a step of arranging the opening at an orthogonal distance of between 1 mm to 10 mm from the top edge.
  • the method may comprise a step of arranging the top panel planar or substantially planar.
  • the method may also comprise a step of arranging the wall section or wall sections comprising the longitudinal sealing band planar or substantially planar, and a step of arranging the top panel at an angle to said wall section or wall sections that is of any one of: within the range of 10 degrees to 90 degrees; within the range of 30 degrees to 80 degrees, within the range of 45 degrees to 75 degrees; and 60 degrees.
  • the step of top-sealing the proto-container at the top sealing region may comprise a sub-step of sealing a plurality of sealing band panels to each other.
  • This sub-step may comprise arranging the sealed sealing band panels parallel or substantially parallel and/or coplanar or substantially coplanar in the container.
  • This sub-step may comprise arranging a central sealing band panel of said sealing band panels such that it extends over the wall section or the wall sections comprising the longitudinal sealing band and has a longitudinal extent being any one of: at least 15 mm, at least 20 mm and at least 30 mm.
  • Fig. 1 shows a first embodiment of a blank 10 for producing a sleeve and, subsequently, a container for holding a pourable food product.
  • the blank 10 can comprise several layers of different materials, for example paper, paperboard, plastic or metal, in particular aluminium.
  • the blank 10 has several crease or fold lines which are intended to facilitate the folding of the blank 10 when produced to form a container and which divide the blank 10 into several regions and sub-regions.

  • the bottom endpoints 18 and 20 form bottom corner points of the blank 10 and the top endpoints 24 and 26 form top corner points. Since the lateral boundary edges 12 and 14 are parallel or substantially parallel, and since the bottom boundary edge 16 is perpendicular or substantially perpendicular to the lateral boundary edges 12, 14, the corner points 18, 20, 24, 26 define a rectangular or substantially rectangular shape. In contrast to the bottom boundary edge 16, however, the top boundary edge 22 is non-rectilinear and extend beyond the rectangular shape defined by the corner points 18, 20, 24, 26.
  • the top boundary edge 22 comprises a plurality of individually rectilinear or substantially rectilinear sections 22a-22i.

  • the top panel 50 comprises a removable section 72 delimited by a loop of weakness 74 allowing section 72 to be removed from the container formed from the blank 10 when the container is initially opened.
  • the loop of weakness 74 may, for example, be a so-called "half-cut", i.e. a cut made partially through the laminated substrate of the blank 10 from the outside surface thereof leaving one or a plurality of inner layers of the laminated substrate intact to provide an uninterrupted barrier against a food product to be contained in the container produced from the blank 10.
  • this region comprises panels 76a-76 partitioned by crease lines 82a-82d.
  • Panel 76c is configured to form a front wall panel of a container produced from the blank 10. Neighbouring panel 76c, the intermediate region 36 comprises panels 76b and 76d which are configured to form side wall panels of the produced container. The panel 76c is partitioned from the panel 76d by a rectilinear or substantially rectilinear crease line 82c and from panel 76b by a rectilinear or substantially rectilinear crease line 82b.
  • the intermediate region 36 further comprises panel 76a neighbouring panel 76b and a fifth panel 76e neighbouring panel 76d.
  • Panels 76a and 76e are configured to form rear wall panel sections of the produced container.
  • Panel 76a is partitioned from panel 76b by a rectilinear or substantially rectilinear crease line 82a and panel 76e is partitioned from panel 76d by a rectilinear or substantially rectilinear crease line 82d.
  • Crease line 82c extends between crease line 28 and the intersection of crease line sections 30c and 30d.
  • Crease line 82b extends between crease line 28 and the intersection of crease line sections 30b and 30c.
  • crease lines 82b and 83c converge. Consequently, the width of panel 76c, i.e. the distance between the crease lines 76c and 76d in the traversal direction T, continuously decreases when moving from the top region 34 to the bottom region 32.
  • crease line 82b is mirrored by crease line 82c and both crease lines 82b and 82c form an angle to the central axis Ca of approximately 2 degrees, although diverging from the central axis Ca in opposite directions.
  • Crease line 82a extends between crease line 28 and the intersection of crease line sections 30a and 30b. Starting from the top region 34 and moving towards the bottom region 32, crease lines 82a and 82b diverge. Consequently, the width of panel 76b increases continuously when moving from the top region 34 to the bottom region 32.
  • Crease line 82d extends between crease line 28 and the intersection of crease line sections 30d and 30e. Starting from the top region 34 and moving towards the bottom region 32, crease lines 82d and 82c diverge. Consequently, similar to panel 76b, the width of panel 76d increases continuously when moving from the top region 34 to the bottom region 32.
  • Crease lines 82a and 82d both form an angle to the central axis Ca of approximately 3 degrees, although diverging from the central axis Ca in opposite directions. Consequently, using the central axis C a as an axis of symmetry, panel 76b is mirrored by panel 76d.
  • the blank 10 also comprises two rectilinear or substantially rectilinear crease lines 92 and 94 extending over the whole length of the blank 10, i.e. between the bottom boundary edge 16 and the top boundary edge 22, parallel or substantially parallel to the central axis Ca.
  • Crease lines 92 and 94 extend centrally or substantially centrally in panels 76b and 76d, respectively, and, consequently, divide panels 76b and 76d into two panel sections 76b-I, 76b-II and 76d-I, 76d-II, respectively.
  • the crease lines 92 and 94 extend centrally or substantially centrally in the gusset panel sub-regions formed by gusset panels 40b-40e and 40g-40j, respectively.
  • Fig. 2 shows a sleeve 96 produced from the blank 10 of Fig. 1 in a rear view and Fig. 3 shows the sleeve 96 in a front view.
  • the sleeve 63 is created from the blank 10 by folding the blank 10 along the two crease lines 92 and 94, bringing panel 76e to overlap panel 76a. In the overlapping region, panels 76a and 76e are then sealed to one another, e.g. welded together, to form a longitudinal sealing band 14 forming a planar or substantially planar rear wall section.
  • the sleeve 96 thus obtains a circumferential structure, closed in the circumferential direction, with an opening in the region of the bottom boundary edge 16 and with an opening in the region of the top boundary edge 22.
  • boundary edge 12 in this case, is covered, either prior to folding the blank 10 along the crease lines 92 and 94 or after the overlapping regions of panels 76a and 76e have been connected to one another.
  • the covering of the open cut edge of the composite material has the purpose of preventing any contact between the contents of the container and this layer, in particular the paper or paperboard layer contained therein.
  • the covering of the cut edge can be achieved by stripping composite layers from the edge and folding a remaining, impermeable layer over the edge.
  • panel 76c is visible as are panel sections 76b-II and 76d-I.
  • the loop of weakness 74 encircling the removable section 72 of the top panel 50 is also visible in the front view. However, the loop of weakness is not visible in the rear view ( Fig. 2 ) since the inside layer of the laminated material of the top panel 50 is unbroken.
  • panels 76a and 76e are visible as are panel sections 76b-I and 76d-II.
  • Fig. 4 shows the sleeve 96 from Figs. 2 and 3 in an erected state.
  • the erected state is arrived at by reversing the previous folding along the crease lines 92 and 94 and folding the sleeve 96 back along the crease lines 92 and 94 by approximately 180 degrees.
  • the folding back along the crease line 92 has the consequence that the two panel sections 76b-I and 76b-II no longer lie on top of one another but become arranged in the same or substantially the same plane.
  • the folding back along the crease line 94 has the consequence that the two panel sections 76d-I and 76d-II no longer lie on top of one another but become arranged in the same or substantially the same plane.
  • the folding back action also involves folding the sleeve 96 along crease lines 82a, 82b, 82c and 82d by approximately 90 degrees, thus forming side edges of the container-to-be.
  • the bottom region of the erected sleeve is folded and sealed. This involves bringing the bottom sealing band panels 38f and 38b into sealing engagement with sealing band panels 38e and 38c, respectively, and bringing bottom sealing band panels 38g and 38s into sealing engagement with sealing band panel 38d.
  • the sealing engagement may be effectuated by welding in a manner which is, as such, known in the art.
  • Folding and sealing the bottom region also involves folding gusset panels 40j and 40g inwards onto gusset panels 40i and 40h, respectively, and folding corresponding gusset panels 40b and 40e inwards onto gusset panels 40d and 40c, respectively.
  • Erecting and bottom sealing the sleeve may be effectuated in a packaging machine (not shown), where the sleeve 96 may be supplied from a magazine and erected on a mandrel.
  • the bottom region may be formed and sealed on the mandrel and the proto-container, i.e. the partially-formed container as shown in Fig. 6 , may then be discharged from the mandrel to a conveyor.
  • the conveyor may transport the partially-formed container to a sterilization station and then to a filling station. In the filling station, a food product may be dispensed into the partially-formed container through the open top.
  • the filled and partially-formed container may then be conveyed to a top-folding and sealing station for folding and sealing the top region.
  • the slanted top panels 44c and 44d are pushed inward at crease line 48 to fold panel 44d over panel 44c and to fold panel 56e over 56f (see Fig. 6 ).
  • a similar operation is carried out on panels 44a, 44b and 56c, 56b (see also Fig. 1 ).
  • the top panel 50 will have assumed a slanted orientation, as shown in Fig. 7 .
  • the panels of the sealing band 56 may be sealed to each other, e.g. in a welding operation, thereby sealing the top region.
  • the folded and sealed sealing band 56 is then folded down onto and attached to the rear wall panels 76a and 76e, as is shown in Fig. 8 .
  • the folded and sealed sealing band 56 forms a top sealing region that is folded onto and is attached to a rear wall section of the container formed from the rear wall panels 76a and 76e, i.e. the wall section containing the longitudinal sealing band 14.
  • a top panel of the container 124 (see Fig. 13 ), formed from panel 50 (see Fig. 3 ), will be free from sealing structures, such as welded, glued or otherwise permanently joined seams where panels of the laminate sheet material are permanently joined to each other. This allows the top panel to be utilised in an efficient manner.
  • a tear-flap may be arranged over and attached to the removable section 72 of the top panel 50 (see Fig. 3 ) to allow easy removal of the removable section 72.
  • Figs. 9-12 shown a container 100 produced from the blank 10 disclosed above.
  • the container 100 comprises a substantially planar bottom portion 102, a top portion 104 and a wall portion 106.
  • the wall portion 106 comprises a front wall section 108a formed from panel 76c and a rear wall section 108c formed from panels 76a and 76e. Further, the wall portion 106 comprises side wall sections 108b and 108d formed from panels 76d and 76b, respectively.
  • An edge 116, formed by crease line 82b defines an intersection of the front wall section 108a and the side wall section 108d, and an edge 118, formed by crease line 82c, defines an intersection of the front wall section 108a and the side wall section 108b.
  • an edge 120 formed by crease line 82a, defines an intersection of the rear wall section 108c and the side wall section 108d
  • an edge 122 formed by crease line 82d, defines an intersection of the rear wall section 108c and the side wall section 108b.
  • the top portion 104 comprises a top panel 124, formed from panel 50, and a sealing region 126, formed from the sealed sealing band 56, i.e. the folded and sealed top sealing band panels 56a-56g, forming a top seal of the container 100.
  • a front edge 132, formed by crease line section 30c, defines an intersection of the top panel 124 and the front wall section 108a.
  • the container 100 also comprises a rear edge 134, formed by crease line section 58c, corresponding to the intersection of the top panel 124 and the sealing region 126. Consequently, the top panel 124 extends between the top edges 128, 130, 132 and 134.
  • the sealing region 126 is folded down onto and attached to the rear wall section 108c, i.e. the wall section formed by the panels 76a and 76e and containing the longitudinal sealing band 14.
  • the panel 76c has a length L F along the central axis C a (see Fig. 1 ).
  • the panels 76a and 76e have a length L B in the direction of the central axis C a that is less than L F . Consequently, the front wall section 108a has a length that is less than the length of the rear wall section 108c (when viewed in the longitudinal direction of the carton 100).
  • This difference in the lengths, i.e., L F ⁇ L B creates an extended configuration of the top panel 124.
  • the front edge 132 is lower than the rear edge 134 when the container 100 is in an upright position as shown.
  • the top panel 124 is at a predetermined angle ⁇ to the rear wall section 108c (see Figs.
  • the angle ⁇ can be about 10 degrees to about 90 degrees, and preferably, about 30 degrees to about 80 degrees. Most preferably, the angle ⁇ is about 45 degrees to about 75 degrees. In the present embodiment, the angle is approximately 60 degrees, as is dictated by the angle between the crease line sections 30b and 30d and crease lines 82a and 82d, respectively (see Fig. 1 ).
  • the planar bottom portion 102 is substantially square-shaped, i.e. it has a width and a breadth of substantially equal length, as is illustrated in Fig. 14a (see also Fig. 5 ).
  • the cross-section of the container 100 when viewed in a plan parallel to the plane of the bottom portion 102, is rectangular.
  • the width of the container 100 is larger than the breadth of the container 100, as is illustrated in Fig. 14b . This asymmetry increases when moving from the bottom portion 102 towards the top portion 104.
  • the container 100 comprises a closure 136 having a tear-flap 138 that covers and is attached to the removable section 72 of the top panel 50 (see also Fig. 1 ).
  • the removable section 72 is delimited by a line of weakness 74 allowing the section 72 to be removed from the container 100 together with the tear-flap 138 when the container is initially opened. Until this first opening, however, section 72 forms, together with the rest of the top panel 124, an uninterrupted barrier for the food product contained in the package.
  • the line of weakness 74 may, for example, be a so-called "half-cut", i.e.
  • an opening 140 (see Fig. 13 ) will be revealed in the top panel 124 through which the food product in the container 100 can be dispensed or accessed.
  • the tear-flap 138 may extend down onto the rear wall section 108c crossing the sealing region 126.
  • the tear-flap 138 may be attached to the container 100 after the container 100 has been filled and top-sealed. Alternatively, the tear-flap 138 may be attached to the proto-container upstream of the filling station.
  • the container in principle, can be fitted with any type of closure known in the art, e.g. a closure comprising a pour spout and a cap resealably arranged on the pour spout.
  • the closure may be implemented using so called pre-laminated hole (PLH) technology.
  • PHL pre-laminated hole
  • such technology involves making a through-hole in the blank and covering the hole with a suitable barrier layer, e.g. a polymer film, which barrier layer is attached to a tear-flap to be removed from the hole together with the tear-flap at a first opening.
  • the opening 140 is positioned close to the rear edge 134 substantially equidistant from slanted edges 128 and 130.
  • the opening 140 may be arranged at an orthogonal distance D of between 1 mm to 10 mm from the fourth top edge 134.
  • the removable section 72 may be arranged at an orthogonal distance D of between 1 mm to 10 mm from the crease line section 58c. Since the sealing region 126 is folded down onto the rear wall containing the longitudinal sealing band 14 and is attached thereto, the top panel 124 will be free from sealing structures and there will be no obstructions extending above the surface of the top panel 124.
  • the longitudinal sealing band 14 and the top sealing region 126 will be confined to the rear wall section 108c of the container. Therefore, when tear-flap 138 and section 72 are removed, the then revealed opening 140 will become easily accessible, in particular from the rear wall section 108c side of the container 100, allowing a consumer to position his or her lower lips on the sealing region 126 and the upper lips over the opening 140.
  • the longitudinal extent of the sealing band panel 56d i.e. the distance A between the crease line section 58c and the top boarder section 22e (see Fig.
  • the length of the sealing region 126 in the longitudinal direction of the container 100 may be at least 15 mm, or more preferably at least 20 mm, or even more preferably at least 30 mm, to comfortably accommodate the lower lips of a consumer and thereby cater for an enjoyable drinking experience.
  • the tear-flap 138 By having the tear-flap 138 extending down onto the rear wall section 108c crossing the sealing region 126, the outer surface of the sealing region 126 intended to come into contact with the mouth of a consumer will be protected until the container 100 is opened.
  • the slanted top panel 124 and the position of the opening 140 close to the rear edge 134 allow for an ergonomically advantageous drinking position, thus making it easy for a consumer to drink directly from the container 100. Consequently, the disclosed container 100 may be suitable to be used as a so-called portion pack, i.e. a type of container configured to hold a liquid intended to be consumed on the go, without the container necessarily having to be reclosed after once having been opened.

  • the blank 10' differs from blank 10 also in that the intermediate region of the blank 10' comprises slanted crease lines 82a'-82g' instead of the substantially longitudinally extending crease lines 82a-82d of blank 10.

  • the sealing region 126' is folded down onto wall section 108d' and wall section 108e' (i.e. the wall section containing the longitudinal sealing band 14') and is attached to the same.
