Definitions

  • the invention relates to a closure for plugging on disposable packs for carbonated drinks, for example on brick packs as are known for fruit juices, icetea or milk.
  • Brick packs are produced from coated cardboard by producing a quasi-endless tube made of this material and filling it alternately and welding and cutting it transversely to the tube direction.
  • the pillow-shaped packages created in this way are brought into the known brick shape by folding in the corner regions. To open it, one of the corners is unfolded and cut off, creating an opening for pouring that can no longer be closed.
  • Larger packs of this type are in some cases also provided with closure units which, in the closed state, are already attached to the above-mentioned tube at regular intervals and which are opened and poured out again by the consumer for pouring.
  • Smaller packs which are intended less for pouring out than for direct drinking, often have a potential opening in the form of a weak point in the pack wall and carry a drinking straw or a closure unit with them.
  • the consumer pierces with the Drinking straw or the weak point with the closure unit.
  • the closure unit can then be opened and closed as desired.
  • the closure according to the invention is essentially tubular with an inner and an outer closure part, which have an inner or an outer end face, the outer closure part being positioned outside the package when the closure is attached, the inner closure part inside the package.
  • the tubular closure is open in the area of the inner end face. In the area of the outer end face, it is area completed, which end area has at least one slot held by elastic stresses in the material in a closed position.
  • a suction effect in this forehead area creates a pressure drop across the forehead area of the closure, as a result of which the contactor or the slots are opened and the beverage can flow out of the pack.
  • the slit or slits
  • the inner closure part of the closure advantageously has a substantially tapered shape so that the potential opening in the package can thus be pierced well.
  • the closure In order for the closure to have a defined, fixed position when it is inserted in the package opening, it is necessary for it to have internal and external retaining means, the spacing of which approximately corresponds to the thickness of the package wall.
  • the inner holding means are shaped in such a way that when they are pressed into the opening they only expand elastically, so that the opening is reduced again after being pressed in and lies tightly against the closure between the inner and outer holding means.
  • the closure advantageously has a shape such that it can be fastened to the broad side of the pack without greatly influencing the shape of the pack and that the pack can be sold in this way equipped.
  • the outer holding means are advantageously in the form of projections which are located opposite one another on two extend the side of the closure, designed, their length is advantageously chosen such that the entire closure becomes so large that it cannot be swallowed by a small child.
  • the closure according to the invention is particularly suitable for brick packs, that is to say cuboid packs made of welded, coated cardboard, in which a corresponding, potential opening is provided for the closure to be attached.
  • Packs of this type in particular small packs of this type, for example with a content of 125 cm 3 , can be held well by a small child with both hands and are flexible enough so that drinking can take place without constant air intake and thus help suction by compressing the pack can be.

  • the closure has a substantially tapered inner closure part 12 and an outer closure part 13.
  • An outer end region 14 closes the closure and has one or more slots 15, for example two intersecting slots as shown.
  • Inner holding means in the form of one or more locking ribs 16 and outer holding means in the form of holding wings 17 are arranged between the outer closing part 13 and the inner closing part 12.
  • the locking ribs 16 and the holding wings 17 advantageously extend alternately around the outer circumference of the closure for manufacturing reasons.
  • FIG. 2 shows the closure 1 according to FIG. 1 inserted in the potential opening 5 of the brick pack 3.
  • the closure is attached to the top of the standing package, centered with respect to the longer edge of this top. This makes it easy to drink while holding the pack with both hands. So that the closure can be positioned well in this position, the potential opening must be made on that side of the upper surface which is not traversed by the longitudinal seam 31, which runs over the entire height of the pack.
  • the holding wings 17 are also clearly visible from FIG. 2, which can also take on a decorative function in addition to their function as external holding means and as protection against choking. Furthermore, the outer closure part 13, outer end region 14 and slots 15 already described in connection with FIG. 1 are visible.

So that a voltage arises in the walls 23, which If slot 15 closes and keeps closed after removal of the molded parts 20 and 21, the outer molded part 21 can be cooled more quickly than the inner 20.
  • the material on the outside of the forehead area solidifies faster and the material on the inside shrinks more, which means that the completely solidified wall 23 creates a tension which pulls it towards the inside and can close the slot 15 and keep it closed.
  • FIG. 6 shows a further exemplary embodiment 2 of the closure according to the invention, again attached to the broad side of a brick pack 3.
  • This embodiment actually represents a double closure, consisting of two interconnected, tubular individual closures. Two potential openings 5.1 and 5.2 are to be provided on the pack for this purpose.
  • the double closure 2 has two tapered, inner closure parts 12.1 and 12.2, two outer closure parts 13.1 and 13.2 with two outer end regions 14.1 and 14.2 and slots 15 made therein.
  • a connecting part 18 is arranged only in the area of the outer closure parts, which not only serves to connect the two individual closures, but also as an external holding means.

  • the closure according to the invention is advantageously produced in an injection molding process from a thermoplastic. It is easily possible to inject two materials into the mold simultaneously. Such a method can be used for purely decorative purposes, in which case, for example, two materials with different colors are used. However, it is also possible to use a softer material (for example amorphous polypropylene or low-density polyethylene) for the outer closure part, in particular for the end region thereof, while for the rest of the closure, in particular the inner closure part. partly a harder material (e.g. crystalline polypropylene or higher density polyethylene) is used.

Abstract

L'invention concerne un système de fermeture à monter sur des emballages jetables (3) pour boissons non gazeuses, qui comprend, après avoir été inséré, une partie de fermeture intérieure, positionnée à l'intérieur de l'emballage (3), et une partie extérieure (13,1 et 13,2) positionnée sur l'emballage. Ce système de fermeture est sensiblement tubulaire et plusieurs systèmes de bouchage tubulaires de ce type peuvent être réunis à l'aide d'au moins une pièce de raccordement (18), pour former un système de fermeture multiple (2). La face avant de la (ou des) partie(s) de fermeture extérieure(s) (13,1 et 13,2) est fermée par des zones frontales (14,1 et 14,2). Il est prévu, dans chacune de ces zones frontales, au moins une fente (15) maintenue fermée par les contraintes exercées sur le matériau. En cas de dépression intervenant dans l'emballage suite à une aspiration exercée depuis l'extérieur sur la zone frontale (14,1, 14,2) ou en cas de surpression suite à une pression exercée sur ledit emballage, la fente s'ouvre et un volume de boisson peut s'écouler par cette fente hors de l'emballage. Ce système de fermeture est particulièrement indiqué pour les jeunes enfants, car lorsqu'il est monté sur l'emballage, ce dernier demeure fermé, sans que le consommateur ait à intervenir.
