Definitions

  • the invention relates to a packaging made of sheet material, such as paper, cardboard or the like, in particular cuboid liquid pack made of cardboard-plastic composite material, with a web seam closure, which can be placed along the top and adjoining it on both sides, by the side wall of the pack Folded triangles which can be delimited by groove lines and which have groove lines extending from the upper side wall edge and extending obliquely to the web seam closure and at least one of which is provided with a tearable pouring opening formed by lines of weakness or the like.
  • sheet material such as paper, cardboard or the like
  • cuboid liquid pack made of cardboard-plastic composite material
  • a pack of this type can be found, for example, in German Patent 1,298,929.
  • a weakening line which runs obliquely to the base line of the closure seam is provided, which consists of a perforation in V-shape or W-shape in the flat state of the packaging material.
  • composite material as is customary for aseptic packs, in which not only aluminum foil but also sometimes tough plastic is used, the tearing of the perforation is nevertheless so difficult that very high forces have to be applied to part of the top seam to tear along the perforation.
  • this is not possible with aseptic packs, since the risk of leakage will then become unacceptable.
  • the invention has for its object to provide a package made of sheet material, such as To produce paper, cardboard or the like with a web seam closure, in particular cuboid liquid pack made of paper-plastic composite material, which can be opened particularly easily by hand.
  • This object is achieved in that the weakening lines are arranged in a U-shaped manner in the wall part forming the folding triangle and of leg-like perforation lines running with a base-like perforation line running parallel to the base line of the web seam closure and perpendicular to it, in the region of the oblique groove lines and striking the base-like perforation line Perforation lines are formed.
  • the perforation in the molded and sealed package is congruent, so that comparatively simple opening steps result from it.
  • the folding triangle only needs to be folded up and the front tip of the folding triangle concerned has to be folded one or more times along the perforation line and then torn off.
  • the folding triangle tip can be torn off with comparatively low forces, since the perforation is pre-folded in both directions by almost 180 ', i.e. can be broken. Since the package does not need to be reshaped to open it, the corner stiffness and thus the grip of the package remains intact.
  • the pouring opening or pronounced pouring spout produced in the manner described has a comparatively large angle of repose, which enables safe, non-drip and targeted pouring. A surge is avoided in any case if a ventilation hole is opened on the side of the pack opposite the opening. After partial emptying, the pouring spout can be folded back onto the side wall of the pack, so that reclosability is achieved in this simple manner.
  • the perforation Due to the special arrangement and design of the perforation, this can be achieved in various ways, for example by a full cut of the uncoated carrier material, such as e.g. Cardboard or in such a way that a half-cut is made in the coated composite from the outside inwards on appropriately designed punches.
  • the congruent arrangement of the perforation in the folding triangle and in the direction of the packaging material in the form, fill and seal machine ensures a simple, sharply defined heat treatment to improve the adhesion of the films in the perforation area.
  • the base-like perforation line being arranged approximately halfway up the vertical of a triangle formed by the side wall edge and the oblique groove lines.
  • the perforation lines are chamfered or rounded in the corner regions abutting one another.
  • This modified cut has the advantage that the starting point for tearing off and tearing off Packing corner always lies on the groove lines even if the perforation lines are offset from the groove lines.
  • the breaking of the corners becomes more effective when bending and bending, since the perforation is stretched more by the curved cut in the corner areas in relation to the molded package.
  • the size of the radius depends on the package format or the basic dimensions of the opening, i.e. the larger the basic dimension, the larger the radius can be, and of the fluctuations to be compensated, i.e. the greater the fluctuations, the larger the radius must be, with the limits that an excessively large radius makes opening more difficult due to the occurrence of excessive tension, and an excessively small radius cannot compensate for the fluctuations.
  • the radius is thus 7.5 to 3.75 mm, preferably 5 mm.
  • a flexible, relatively stiff web-shaped material for example in the form of a blank 3, which is only partially shown in FIG. 1, is used to produce a pack with side walls 1, an upper end wall 2 and an invisible bottom wall shown in FIG.
  • the blank is brought into a tubular shape for the production of the pack and closed by closing a longitudinal seam, a bottom seam and a closing seam 4 attached on the head side.
  • the web seam closure 4 is limited by a base line 5 with respect to the material of the side walls 1.
  • the pack has folding triangles 6 on the upper underside which can be folded over on both sides and placed on the side wall of the pack. Each of the folding triangles is folded over a side wall edge 7 and fastened to the adjacent side wall by means of an easily detachable adhesive connection.
  • the closing seam 4 extends over the folding triangle 6, the upper end wall 2 and the folding triangle (not shown) folded down onto the invisible side wall of the packaging.
  • the pack is also provided with groove lines 8, 9 and 11, 12 and 13, the groove lines 8 and 9 delimiting the transitions between two adjacent side walls 1 of the pack and the groove lines 11, 12 and 13 lying in the region of the folding triangle 6.
  • the groove lines 11, 12 are arranged obliquely to one another, in such a way that they form a triangle together with the side wall edge 7 and the groove line 13 lies on a vertical of this triangle.
  • lines of weakness which are arranged in a U-shaped manner in the wall part forming the folding triangle and consist of a base-like perforation line 14, which runs parallel to the base line 5 of the web seam closure 4, and two leg-like perforation lines 15, 16, the latter and meet the base-like perforation line 14 on the oblique groove lines 11, 12.
  • the perforation lines 14, 15, 16 lie congruently on the inside and outside of the folding triangle, so that the folding triangle is divided by the perforation lines parallel to the side wall edge 7 into two sections.
  • the folding triangle is folded up, the front folding triangle tip is pre-folded or broken by 180 in both directions around the perforation lines 14, 15, 16 and then the folding triangle tip is torn off. Then only a ventilation hole 17 located on the opposite side in the end wall 2 needs to be opened in order to enable the contents of the package to be poured out without gushing.
  • the package does not need to be reshaped when torn, i.e.
  • the grommet produced in the manner described and shown in FIG. 3 can be folded back down onto the side wall, so that the pack can be closed conditionally.
  • the pack can still be easily opened because a bevel or rounding 10 in the corner area between the perforation lines 14, 15, 16 always on the groove lines 11 and 12 comes to lie. As a result, there is always a starting point lying on the groove lines for tearing and tearing off the packaging corner.
  • the perforation is stretched more strongly in the selected arcuate cut, so that the breaking of the corners becomes more effective when bending up and down.
  • the radius of the rounding should roughly correspond to the maximum expected range of fluctuation.
