Definitions

  • the present invention relates to a packaging container with an opening device
  • Consumable liquid or pasteurized food products are often sold in packages made of sterilized packaging material.
  • Typical examples for such packages include the Tetra Brik® or Tetra Brik® Aseptic in the shape of a brick stone, or the Tetra Fino® package more resembling a pillow or pouch.
  • the packaging material used for those packages comprises a multilayer structure.
  • One or more layers of plastics, and aluminum foil (depending on the package type) are laminated on both sides of a card board of paperboard layer, the latter having different stiffness, strength and thicknesses depending on the package type.
  • Packages of this sort are normally produced on fully automatic packaging machines, on which a continuous tube is formed from the web-fed packaging material; the packaging material is sterilized inside the packaging machine, e.g. by radiating the web using a low voltage electron beam or a chemical sterilization agent. The material is then folded in a sterile environment and sealed longitudinally to form a vertical tube.
  • the tube is filled with the sterilized or sterile-processed food product, is sealed transversally and subsequently cut along equally spaced cross sections to form pillow packs and sometimes further processed to substantially parallelepiped-shaped, packages like the above mentioned packages.
  • container for the purpose of the invention the terms container, package and packaging container refer to the same structure.
  • material, material laminate structure or package material refers to the package material laminate structure used in the packaging container.
  • the invention proposes a packaging container for pourable food product, which has a width, height and depth.
  • the packaging container is closed by a first transversal seal in a top portion of the packaging container, a second transversal seal in a bottom portion of the package as well as longitudinal seal.
  • transversal seal in this regard refers to a seal substantially perpendicular to the longitudinal seal.
  • the longitudinal seal normally extends substantially across the length or height of the package. In other words, the transversal seal spans across the width or depth of the packaging container.
  • An opening device on a first side of the packaging container comprises at least a tab portion and an opening strip portion.
  • the tab portion is arranged on an outer surface of the first side and coupled to the opening strip portion via a material bridge penetrating through the material of the first side, such that it opening devices ruptures the material during opening of the packaging container.
  • the opening portion is attached on an inner surface of the material of the first side extending along a substantial portion of the first side and particular a substantial portion of the width of the first side.
  • an opening device is arranged on a package, which enables the package to be ripped open across substantially the whole width of the package. Hence, a relatively large opening is created allowing the food to be poured quick and efficient.
  • the opening strip portion provides a predetermined rupture line, on which the packaging container is ripped open, so a random opening, (often a problem in packages without such predetermined lines) is prevented.
  • the opening strip portion may be arranged close to the top transversal seal, particularly above a level of pourable food product filled into the packaging container. This allows a quick opening reducing the risk of spoiling liquid food.
  • the transversal seal closer to the opening device may be folded away from the opening device. In such arrangement it has been found that the package sides extend outwards increasing the opening.
  • a distal end of the opening strip portion is arranged substantially at an edge, i.e. a longitudinal edge of the packaging container.
  • the opening strip portion then may extend substantially parallel to the seal towards another seal of the packaging container.
  • the material bridge and the proximal end of the opening strip portion may be arranged close to or substantially at an edge, i.e. a longitudinal edge of the packaging container.
  • distal end refers to the end of the tab portion which is furthest away from the tab portion or the material bridge. Accordingly, the proximal end of the opening strip portion is the end closest to the material bridge.
  • the opening strip portion extends along more than 40% of width of the package, particularly more than 60% or even more than 80%. In some embodiments, the opening strip portion may extend substantially along the whole width of the packaging container reduced by the dimension of the tab portion.
  • the opening strip portion is arranged closely to a transversal edge of the first side substantially parallel to the first transversal seal.
  • a “transversal edge” is an edge of the package along its width. As in such case the edge separates the packaging container into a top side portion and a main side portion, the opening device and particularly the opening strop portion of the opening device may be arranged on the top side portion. Alternatively, the opening strip portion can be arranged directly on such edge.
  • the material of the package may comprise a laminate structure with a plurality of layers and a weakened area, in which the bridge is penetrating the material laminate structure.
  • a thickness of the material laminate structure is reduced.
  • the bridge and the opening device can be manufactured by injection molding or similar technologies. The material of the bridge is injected into the material and penetrates the weakened area. If the material structure laminate itself is thin enough, then the material bridge and the opening device can be arranged directly on the material without having a specific weakened area.
  • the material and thickness of carton based layer being part of the material layer is crucial for the decision if a weakened area is needed or not.
  • the opening device comprises a support portion to facilitate opening the package along the predetermined rupture line provided by the opening strip portion.
  • the support portion may be arranged on the outer surface adjacent to an area opposite the opening strip portion.
  • the support portion may be arranged closer to the bottom of the packaging container, or the second transversal seal and may comprise a strip similar to the opening strip portion but arranged on the outside of the package.
  • the support portion may circumvent the opening strip portion on both sides on the outer surface. Such arrangement of a support portion provides an even better opening and predetermined rupture line. It may also stabilize the material during the opening process, reducing the risk of spoiling any liquid.
  • a distance (in the longitudinal direction) between the opening strip portion and the support portion is in the range of 0.1 to 2 times the thickness of material laminate structure.
  • the support portion is arranged very closely to the opening strip portion.
  • the opening device including all support and opening strip portions may be made of plastic material.
  • the packaging container and more particular the side, on which the opening is arranged may comprise one or more compression or crease lines extending from the opening strip portion as to facilitate the shape of the opening upon exerting pressure on the packaging container with a component parallel to the transversal direction.
  • the side of the packaging container may comprises two compression lines extending close from or from respective edges of the opening strip to a common intersection on said side or a bottom edge of the first side.
  • the side further comprises a third compression line extending from substantially a center or close thereto of the opening strip along the longitudinal direction towards the second seal.
  • the side may comprise at least two compression lines extending from substantially a center or close thereto of the opening strip towards a bottom edge of said side or a side edge of said side.
  • the method comprises the step of providing a packaging material blank or web having crease lines for a container to be folded and an area of weakening.
  • An opening device is attached to the packaging material blank, the opening device having a tab portion, an opening strip portion extending substantially parallel along a crease line separating a min panel side for a top closure panel side.
  • the tab portion is connected to the opening strip portion via a bridge through the material laminate structure of the packaging material blank.
  • the packaging material blank comprises a weakened area, which lacks one or more layer of the material laminate structure.
  • the bridge connecting the tab portion the opening strip portion penetrates the weakened area.
  • the blank with the opening tab is bottom folded, filled and finally sealed.
  • the blank is part of a web, in such case the web is folded into a tube and then longitudinally sealed, before a liquid is filled into the tube.
  • the tube is sealed as to for a bottom and top sealing and then separated.

  • the packaging container 1 has a width extending along a transversal direction T and a length extending along a longitudinal direction L.
  • the packaging container contains liquid pourable food and comprises a package material structure laminate made of a plurality of different layers. These layers include a carton based layers for stability and one or more plastic material layers acting as décor layer for protecting a print on the outside or as a gas barrier on the inside. In some cases a light barrier layer, e.g. aluminum is included in case of aseptic packages with a long shelf life.
  • the pouch like packaging container 1 is sealed on the top and bottom by a transversal seal 11 and 10 , respectively, and folded as to form a front side 18 and a back side 19 .
  • a longitudinal seal (not shown) is arranged from the top transversal seal 11 to the bottom seal 10 .

  • Said opening device includes on the front side 18 a tab portion 14 in the shape of a drop with some ripple for an improved grip and a support portion 16 and 13 .
  • Support portion 16 surrounds an area around the tap portion while support portion 13 extends along the transversal direction T almost all along the width of the package. It surrounds a small elongated area 17 of material.
  • Tab portion 14 is connected in an area 15 of the material laminate with an opening strip portion 17 a arranged on the inner surface of front side 18 .
  • Said opening strip portion 17 a shown in FIG. 2 extends as an elongated strip all the way till the distal end of support portion 13 . It is connected to the tab portion by a material bridge penetrating through the material laminate and predetermines a rupture line.

  • the opening device extends from an upper outside corner 27 of the packaging container along substantially the whole width in the transversal direction T to a weakened area 209 close to the other upper corner and the edge 28 .
  • Two support strips extend along the width of the package, a first one on the top portion of the packaging container, right adjacent to the edge, and a second support strip 203 on the front wall adjacent to the edge. The two strips thereby enclose the edge of the packaging container separating front wall 20 from top portion 23 .
  • the opening device comprises a tab 201 in the shape of a pull tab of a zipper like-alike, which is flatly arranged on the top portion 23 .
  • Tab 201 is connected via a material bridge to an opening strip portion (not shown) arranged on the inside of the package along the edge to corner 27 .
