Definitions

  • the invention relates to an assembly for use in the manufacture of gable top containers, which can be applied in the food industry and more particularly in the production of packaging for liquid, beverage or other good.
  • the gable top containers are well known for a long time and have become very popular.
  • Many containers, used to hold liquids and foodstuffs, are made from a packaging laminate such as laminated paperboard or cardboard.
  • These laminates typically include a thin layer of a plastics material such as polyethylene covering at least one side of a sheet of paperboard or other fibre-based material.
  • the laminate is folded to form the container, so that the plastics layer is on the inside and provides a barrier layer, that prevents the content of the container from coming into contact with the paperboard.
  • These containers are not easy to be recycled due to the intimate bond between the plastics layer and the paperboard. The whole container, therefore, typically ends up in landfill.
  • the known assembly consists of blank and pouch.
  • the blank of the assembly has two sides and is made from a sheet of paperboard.
  • the blank has top edge, bottom edge and two side edges and includes four wall panels, each having top edge and bottom edge.
  • the wall panels are arranged adjacent to each other across the blank.
  • the blank has gable panels and top gusset panels, which are extended from top edges of the wall panels and the blank has base panels and bottom gusset panels, which are extended from the bottom edges of the wall panels.
  • the blank has also three tabs, which are extended from the first wall panel and four fin panels, which additionally extended from gable panels and top gusset panels.
  • the top edge of the blank is defined from the edges of the fin panels, and the bottom edge is defined from the edges of the bottom gusset panels and base panels.
  • the first side edge is defined from the side edges of first fin panel, first wall panel and first bottom gusset panel, and the second side edge is defined from the side edges of last fin panel, last wall panel and last base panel.
  • the blank has an aperture for spout element in the first gable panel.
  • the pouch has an opening with perimeter, which is equal to the distance between opposing side edges of the blank.
  • the pouch has an aperture for spout element and the pouch is adhered to first side of the blank, so that both apertures for spout element are aligned to each other.
  • the known assembly for use in the manufacture of gable top containers has a line of weakness, extending around at least part of the periphery of the assembly and defining a first portion of the gable top container on one side of said line of weakness and a second portion of the container on the other side of said line of weakness.
  • the line of weakness is permitting the first portion of the container, made from the known assembly, to be separated from the second portion.
  • the known assembly for use in the manufacture of gable top containers from EP3204313 permits recycling of at least part of the container, made out of it, so the gable top container is not suitable to be fully recycled. After separating the first portion from the second portion, part of the cardboard of the blank remains firmly glued to the pouch. These parts of the assembly cannot be recycled without the intervention of a consumer, who must separate the cardboard from the assembly, wherein in most cases the adhesive and the cardboard remain on the pouch.
  • the present invention discloses an assembly for use in the manufacture of gable top containers, which consists of blank and pouch.
  • the blank has two sides and is made from a sheet of paperboard.
  • the blank has top edge, bottom edge and two side edges and includes four wall panels, each having top edge and bottom edge, so that the wall panels are arranged adjacent to each other across the blank.
  • the blank has gable panels and top gusset panels, which are extended from top edges of the wall panels and the blank has also base panels and bottom gusset panels, which are extended from the bottom edges of the wall panels.
  • the blank has tab and four fin panels, which are extended from the edges of gable panels and top gusset panels.
  • the top edge of the blank is defined from the top edges of the fin panels.
  • the bottom edge of the blank is defined from the bottom edges of the bottom gusset panels and base panels.
  • the first side edge is defined from the side edges of the first fin panel, the first wall panel and the first bottom gusset panel.
  • the second side edge is defined from the side edges of the last fin panel, the last wall panel and the last base panel.
  • the blank has an aperture for spout element in the first gable panel.
  • the pouch has an opening with perimeter, which is equal to the distance between opposing side edges of the blank, and the pouch has an aperture for the spout element. The pouch is adhered to the first side of the blank, so that both apertures for the spout element are aligned to each other.
  • the tab is extended from the first side edge of the blank and has length, equal to the distance between the top and bottom edge.
  • the pouch is adhered to the blank in heat sealing dots, which are applied in equal intervals on the first side of the blank in such a way, that the heat sealing dots are placed:
  • the blank is coated with adhesive in heat sealing layers, wherein the first heat sealing layers are of strip type and are applied:
  • the second heat sealing layers are applied in bottom corners of base panels on the second side of the blank in such a way, that the second heat sealing layers are forming triangle areas, which are defined between top corners, bottom corners and the middles of the bottom edges of bottom gusset panels.
  • both side edges are bonded together, using the tab, along which there is additional heat sealing layer on the second side of the blank.
  • the pouch is made from laminated polymeric or metallic material.
  • the adhesive for all heat sealing dots and layers is water based or is one of the following: Vinyl Acetate Ethylene (VAE), Ethylene-vinyl acetate (EVA), Polyurethane (PU), Polyvinyl alcohol (PVOH) or Polyvinyl acetate (PVA).

  • the pouch 2 has also an aperture 19 for the spout element 17.
  • the pouch 2 is adhered to the first side A of the blank 1, so that both apertures 16, 19 for the spout element 17 are aligned to each other.
  • the tab 14 is extended from the first side edge 5 of the blank 1 and has length, equal to the distance between the top edge 3 and bottom edge 4.
  • the pouch 2 is adhered to the blank 1 in heat sealing dots 20 (shown on FIG. 2 ), which are applied in equal intervals on the first side A of the blank 1 in such a way, that the heat sealing dots 20 are placed:
  • Three more heat sealing dots 20 are placed circularly around the aperture 16 of the blank 1, so that each one of them is offset by an angle of 90° from the previous one and the first one of them is offset by an angle of 90° from that heat sealing dot 20, which is placed above the aperture 16 of the blank 2.
  • the blank 1 is coated with adhesive in heat sealing layers 21, 22 (shown grey on FIG. 3 and 4 ), wherein the first heat sealing layers 21 are of strip type and are applied:
  • the second heat sealing layers 22 are applied in bottom corners of base panels 12 on the second side B of the blank 1 in such a way, that the second heat sealing layers 22 are forming triangle areas, which are defined between top corners, bottom corners and the middles of the bottom edges of bottom gusset panels 13.

More importantly the area of adhesion around the apertures 16, 19 is also has four heat sealing dots 20, placed on the blank 1. In one embodiment of the assembly, there are additional heat sealing dots 20' on the blank 1, which are sustaining more reliable the pouch 2 to the blank 1. The pouch 2 is adhered to the blank 1 in all heat sealing dots 20 and 20'.
  • the gable top container is formed by the assembly (shown on Fig. 5 ), according to the present invention, wherein during the construction process of the container, the tab 14 on the first side edge 5 is bonded to the last wall panel 7, the gable panel 10 and base panel 12, respectively to the opposite side edge 6 to form a tube or sleeve (shown on FIG. 6 ).
