Definitions

  • the invention relates to a tear-open tab opening on packages made of plastic-coated composite material with a folded seam seal.
  • ash tear l which are formed integrally with the package.
  • European patent application 39 11 6 a liquid pack with a tear-open tab opening is shown and described, into which a straw can be inserted.
  • the drinking straw hole is in the side seam of the Integrated package and by turning on and cut-outs in this be - borders.
  • an incision can also be made in the covered seam part in order to detach the cover layer from the composite material when tearing and to avoid incorrect openings.
  • the pull tabs created in this way are very short and easier to handle only when using complex shape cuts.
  • the tear-open tab opening is also arranged in the area of an overlap seam, which can therefore only be used for product groups that do not require any all-round edge protection. It is therefore not suitable for aseptic packs.
  • a further tear tab opening has become known from US Pat. No. 4,244,474, in which a tear tab can be formed by incisions in the carrier material of the composite material that run parallel to one another. This finally merges into a circular opening, which, however, like the surface between the cuts, is still covered by the non-severed layers of the composite material. This opening can therefore only be used and is therefore only designed for this purpose. if this existing layer is pierced with a straw.
  • the invention is therefore based on the object of creating a tear-open tab opening on packs of plastic-coated composite material with a folded seam seal, which can be produced simply and inexpensively without the use of elaborate shape cuts and which is easy and convenient to handle while avoiding uncontrolled damage to the folded seam seal.
  • the folded-over web seam closure in at least one through an incision in the first packing area in a first seam region extending from a longitudinal edge of a first packing surface to approximately the folded-over edge of a second packing surface connected to the first packing surface via the web seam closure formed full cut and in a second seam area adjoining the first seam area in extension of the full cut has at least one weakening line which extends beyond the second seam area into the area of the first pack area contacting the filling material of the pack.
  • the weakened line or lines of weakness are formed by a one- or multi-layer wall of the first P ackungs preparation only partially separated half-section. It goes without saying that a perforation can also be used instead of a half cut.
  • the first seam region or the full cuts has a wider design than the second seam region or the half cuts.
  • an anti-adhesive can be applied in the area of the ridge seam closure delimited by the full cut or the half-cuts between the top of the second packing area and the adjacent underside of the first packing area and the bottom of the folded edge.
  • the tear-open tab opening can easily be opened via the scribing tab and the subsequent detonation of the edge protection and the inner coating. so that the product space is easily accessible.
  • the opening flap delimited by a single full cut can be arranged in a corner region of the web seam closure or else in the central region thereof.
  • the area delimiting the opening tab is formed by two full cuts that are spaced apart. Weakening lines can then be connected to the full cut (s) in the desired manner, e.g. in such a way that a dividing strip running around the pack is formed between the weakening lines, or else in such a way that the two full cuts are connected to one another by a common half cut.
  • the tear-open tab opening or the full and half cut in the film cut necessary for this purpose can be made very easily on a pressure die-cutter, with no complicated shape cuts being necessary for the blank production, but rather via roll cuts. Longitudinal and cross cutters can be made.
  • Strength in F. 1 shows a blank of a composite material for the production of a package.
  • the composite material consists in a known manner of an outer plastic coating, a carrier material consisting of cardboard or the like, a lamination film. an aluminum layer and an inner plastic coating.
  • the blank 1 comprises pack surfaces 2. 3. 4, 5, and 6, the package surface 2 in the further course of the description as the first P ackungs Type and the package surface 6 is referred to as a second package surface. After folding the blank 1 along groove lines 7 provided therein, the first packing surface 2 and the second packing surface 6 can be connected to one another by means of a folded-over web seam, as shown in FIG. 3.
  • An incision in the form of a full cut 8 and a further full cut 9 and subsequent weakening lines in the form of a half cut 11, 12 are made in the packing surface 2.
  • a further weakening line 13 can be provided in the packing surfaces 5 and 6, the purpose of which is explained in more detail below.
  • the full cut 8 extends over a first seam region 14 of the web seam closure 10.
  • the first seam region 14 is wider than a second seam region 15, over which the half-cut 1 extends and which finally extends even further over the packing surfaces 2 and 3 extends.
  • the full cut 8 runs parallel to an edge 16 and transversely to a further edge 17 of the packing surface 2.
  • the full cut 8 forms a scribing flap 18 in the web seam closure 10, below which a further flap parallel to the edge 17 for easier entrainment of the material from the packaging surface 6 Line of weakness in
  • the shape of a half-cut 19 runs, namely at a short distance of up to approximately 3 mm from the edge 17.
  • a package 21 provided with such a tear-open tab opening is shown in FIG. 4. It can be seen here that an opening can be achieved via the tear-open tab 18 and by entraining the material of the packing surface 6 and tearing along the half-cut 11, as will be explained further below.
  • a blank 1 is assumed. in the case of which two full cuts 22, 23 are made in a central region of the folded web seam formed, to which half cuts 24, 25 are connected to form a separating strip 26, which runs around the pack to be formed and is suitable, for example, for frozen packs.
  • FIG. 5 also shows a further modified representation, two full cuts 27, 28 being arranged at a parallel distance from one another and being connected to one another via a common half cut 29.
  • the full cuts 27, 28 extend over the first seam region 14 and the weakening line 29 over the second seam region 15 and the packing surface 2 contacting the filling material.
  • an anti-adhesive agent 31 is applied to the folded edge of the web seam closure, the area of which is slightly larger than the area delimited by the full cuts 27, 28 and the edge 17.
  • the pack 3 2 provided with such a tear-open tab opening is shown in FIG. 8 shown.
  • Such an opening is suitable, for example, for pourable, powdery goods.
  • a full cut is a cut which cuts through the entire V erbundED, while a half-section cuts through only the outer plastic coating and the carrier material, while the other layers can be intact.
  • FIG. 9 to 11 each show the order in which the opening of the pack is generated.
  • the tear-open tab opening is arranged in the region of a headstitch seam 33 of the pack, an ear of the pack formed by a folding triangle 34 is folded into the horizontal. Then the scribing tab 18 is gripped and folded up.
  • the layer of the second packing field 6 underneath is then entrained in a precisely controlled manner by detonating the edge protector (FIG. 10) and then the opening is made by tearing along the lines of weakness, as is shown in FIG. 11.
  • further weakening lines can be provided in order to achieve different openings, e.g. a pouring opening according to FIG. 12, a drinking opening according to FIG. 13 and a spoon opening according to. 14 and 15.
  • a line of weakness can also easily be formed by the sealing seam edge of the head web seam 33, as is indicated in FIG. 11. If you want to achieve a larger opening, the lines of weakness have to widen outwards from the full cuts in order to finally converge towards the front. It is important that the opening tip extends into the area of the ear-like folding triangles 34, since only in this way is it possible to pour out a filled product properly.
  • the introduction of the solid and H albitese is conveniently carried out together in one operation with printing. Grooving and punching the finished coated composite material through a foil cut of a pressure punch.
  • the line of weakness 29 running parallel to the edge 17 can also be introduced further inwards and also in connection with the non-stick agent. so that the bond to be traversed is brought to half the strength when the web seam is not peeled and thus the tearing is facilitated.
