Definitions

  • the invention relates to a liquid pack made of an overcoated cardboard composite with a pierceable straw opening.
  • the punched or flap holes are made in the extruder before coating the multi-layer cardboard composite and then overcoated, for example with a polyethylene layer (DD 201 659).
  • DD 201 659 polyethylene layer
  • a further possibility of making the punched-outs in the multilayer cardboard composite is to make the punched-outs after coating in the extruder through half or double cut openings (DE 70 37 657 A1).
  • Half-cut openings are to be understood as punched-outs which - introduced from the outside - only partially pass through the cardboard composite, while double-cut openings are those in which incisions of different sizes are made from opposite sides of the cardboard composite.
  • the commission commitment only begins in the punching or printing machines.
  • punchings introduced in this way that is to say in the final equipment, it is not possible to obtain a substantial seal between the drinking straw and the punching out, unless the drinking straw and the punching out are matched to one another in diameter. If there is no exact coordination, it is difficult to control the unintentional leakage of the filling material from the injection point next to the drinking straw.
  • the invention has for its object to provide a liquid pack of the type mentioned, in which an optimal adaptation of the straw opening to different diameter and cross-section straws can be achieved in a simple manner and thus an uncontrolled leakage of the contents from the injection site next to the straw is avoided.
  • the drinking straw opening is formed by radially extending incisions.
  • a drinking straw opening is obtained which can be opened to different degrees by the drinking straw, so that it adapts to drinking straws of different sizes.
  • the straw opening can be expanded to any center according to the diameter of the straw when the straw is inserted via the flaps located between the incisions and in any case lies sealingly against the straw. It follows that a uniform, comparatively small opening diameter is sufficient for a wide variety of drinking straw sizes.
  • the danger of pin-hole formation which otherwise exists during extrusion, in particular in the case of comparatively large punched-outs can be avoided in this way.
  • the drinking straw opening according to the invention can be used both in the uncoated cardboard - for example extruder - and in the finished coated cardboard multilayer composite in the form of a half or Make a double cut.
  • the incisions are arranged in a star shape relative to one another.
  • the central star point of the incisions is recessed in a circle.
  • the circular recess should have a diameter that is smaller than half the diameter of the circumference of the star-shaped incisions.
  • a hole-star cut combined in this way is introduced into the extruder before the coating of the cardboard multilayer composite.
  • Half-cut process i.e. in the finished coated composite, insert such star-cut holes.
  • opening the drinking straw opening is made considerably easier if the star point is cut out in a circular manner.
  • the size of the drinking straw used for the piercing as well as the central recess and the incisions must of course be roughly coordinated. It has proven to be particularly favorable if, with a diameter for the drinking straw between 3 and 8 mm, the recess in the star point has a diameter of 1 to 3 mm, preferably 2 mm, and the star cut has four to twelve cuts, preferably eight cuts.
  • the incisions and / or the recess can be formed by a half or double cut, which is preferably overcoated.
  • at least the recess can also be formed by an overcoated full cut.
  • the introduction of a drinking straw opening into the cardboard multilayer composite in a liquid pack can expediently be carried out in such a way that the radial or star-shaped incisions are first made in the cardboard multilayer composite and this is then overcoated.
  • the possibility of making the radial or star-shaped incisions in the multilayer cardboard composite after coating it At least for the central, circular recess, it has proven to be advantageous if it is introduced as a full cut into the multilayer cardboard composite and this is then overcoated on both sides.
  • a blank 1 with several side wall parts 2, 3, 4, 5, 6 is shown in FIG. 1, the individual side wall parts of the blank 1 being separated from one another by fold lines 7.
  • a drinking straw opening 8 in the form of a star cut, which is shown on an enlarged scale in FIG. 2.
  • the star-shaped drinking straw opening 8 has a central recess 9 and, starting therefrom, star-shaped incisions 11.
  • the recess 9 at the star point of the incisions 11 extending in a star shape and the incisions 11 themselves can be arranged in the cardboard multi-layer composite 12 in various ways .
  • the cardboard multilayer composite consists of a cardboard layer 13 and a coating 14, 15 arranged on the inside and outside thereof, for example made of polyethylene. In a manner not shown, further layers can be provided, e.g. an aluminum layer.
  • the incision 11 is designed as a half-cut. This half-cut is made in the extruder before coating the cardboard multilayer composite 12.
  • the corresponding incision 11 is arranged and designed accordingly.
  • the central recess 9 is, as can be seen from the right part of FIG. 3, designed as a full cut and then coated on both sides.
  • an incision 11 is shown, which is made as a half-cut in the uncoated carton and then covered by coating 15.
  • an incision 11 is shown in FIG. 5 as a half-section, which is only after the coating is introduced into the cardboard multilayer composite 12 by means of a rotary roller or the like.
  • the inner coating 14 is pierced when a drinking straw 16 is inserted into the drinking straw opening.
  • the star flaps 17 lying between the incisions are correspondingly expanded centrally, so that they lie sealingly against the drinking straw 16 because the carton tears in the predetermined cuts 11, but not the flexible, stretchable coating 14.
  • the tension resulting from the stretching of the coating also ensures that the drinking straw 16 cannot slip into the liquid pack in an uncontrolled manner.
  • each incision could in principle also be designed as a full cut.
  • the drinking straw used for piercing need not be circular in cross section, but rather can also be oval or polygonal in cross section.
