Definitions

  • This invention relates to a closure for composite packages with a special tamper-evident device.
  • composite packagings particular mention is made of liquid packings made of film-coated paper in which, for example, milk, fruit juices, all kinds of non-alcoholic beverages or generally liquids are also packaged from the non-food sector.
  • the closure can also be used for composite packages in which bulk goods such as sugar, semolina or all kinds of chemicals and the like are stored or packaged.
  • This packaging material is a laminate, for example a paper or board web coated with polyethylene and / or aluminum. Common volumes of such packages range from 2OcI to 2 liters and more. Plastic closures for composite packings are known in various designs.
  • spout connecting piece which has a final flange at its lower edge.
  • the nozzle is provided with an external thread on which a threaded cap can be screwed.
  • Such a closure is flanged onto the composite package by sealingly sealing or adhering to the bottom of its flange on the composite package. The free passage at the lower end of the nozzle is then closed by the composite packing material.
  • the foil-type film which passes through underneath the welded-on neck Strengthened paper or the film membrane running inside the nozzle must be cut open, torn open or pushed away to open the passage and the liquid or the bulk material can be poured out or poured out of the container through the nozzle.
  • various opening aids can be used.
  • a sleeve is arranged in the interior of the nozzle, which is pressed down upon rotation of the screwed cap from this.
  • the lower edge of the sleeve is equipped with one or more tearing or incisors.
  • the sleeve should cut out as a result of their downward movement of a disc from the continuous film under her foil-reinforced paper or the membrane membrane there.
  • the lid may have on its inner side a sleeve which projects into the neck, rests on the bottom through continuous Foüe and is the same, Versehweisst. When the lid is turned, the disc-shaped piece of film, which is welded on at the bottom, is torn out.
  • the webs tear slightly outside the Anformstelle on the outside of the lid edge, that is, the predetermined breaking points are located slightly outside the lid outer surface. They leave behind unsightly, sharp-edged burrs. Inadvertence here is a risk of injury. The same applies to the torn-off bridges whose tips are also sharp-edged.
  • the object of this invention is therefore to provide a closure with tamper-evident device which overcomes these problems. First, it should be openable by anyone without effort, and second, it should also be designed so that a risk of injury is excluded in its operation.
  • Figure 1 The closure in a side view
  • Figure 2 The closure before opening in plan view
  • FIG. 3 The closure during the first opening in the plan view, after the half-turn to overcome the Clearö Stammsgarantie device
  • Figure 4 The closure during the first opening in plan view, just before the breakage of the webs;
  • Figure 5 the closure after removing the lid;
  • Figure 6 The closure after screwing the lid.
  • FIG. 1 shows the closure in a side view. It consists of a cover 1, which is screwed onto a threaded connector 2, wherein the nozzle 2 is on a flange 3. On the left side you can see the footbridges
  • the webs 4 are formed on the outside 5 of the lid 1, that the thin spot 8 is in the surface of the outside 5 of the lid 1 and with the same is flush and does not project from the same.
  • the thin areas 8 are on the outside
  • the plate 6 is mounted on the flange 3, for which purpose it has formed on its underside pin 7, which fit into corresponding holes on the flange 3.
  • the webs 4 are formed so that they taper from the plate to the lid 1, to its thin spot 8, with which they are integrally formed thereon.
  • FIG. 2 shows this closure before opening in plan view.
  • the webs 4 for the Clearö Stammsgarantie device are arranged obliquely to the radial R of the lid 1, which leads to the center of the plate 6 and extends centrally with respect to the webs 4. These webs 4 always run at an acute angle in the counterclockwise direction pivoted to this radial R.
  • the webs 4 are integrally formed on the common plate 6, from which they taper towards the lid 1 and on the outside 5, they are each about a fine Thin spot 8 are formed.
  • the webs 4 are arranged parallel to each other in the example shown, but each includes an acute angle with the radial R, which passes through the center of the plate 6.
  • 3 shows this closure during the first opening of the lid 1 in plan view.
  • the cover 1 is here so far in the opening direction, that is rotated counterclockwise, that about half the rotational movement to overcome the Warö Stammsgarantie device was covered. Up to this position, the webs 4 are curved.
  • Figure 4 shows what happens with further rotation of the lid 1 in the opening direction.
  • the webs 4 are stretched and finally tear the thin spots 8, so that the webs 4 are released from the lid 1. Since the webs 4 are arranged to extend parallel to one another as shown, the web 4, which precedes in the direction of rotation, first rips 4. Thereafter, the middle and finally the last web 4 are torn off the cover 1 in the direction of rotation. Thus, the forces to tear the thin parts 8 are not added, but each thin piece 8 is separately and separately separated. The necessary force is therefore reduced to one third, but must be spent three times. As soon as a web 4 is torn off its thin spot 8, it pivots back in the direction indicated by an arrow.
  • the middle web 4 now runs along the radial R or at least almost along the radial R, and the two outer webs 4 are approximately parallel to it. The webs 4 are thus in a relaxed position and extend with their tips close to the outer surface of the nozzle. 2
  • the webs 4 lead from the lower side of the lid edge obliquely downward to a plate 6.
  • the thin areas 8 are then in the plane of the underside of the lid edge.
  • the webs are in turn formed so that they taper from the plate 6 in the direction of the lid 1 out.

Abstract

La fermeture de l'invention est constituée d'une tubulure de déversement (2), pourvue d'un collet (3) et pouvant être montée de manière étanche sur un emballage composite, et d'un bouchon associé (1). Le bouchon (1) est relié via des éléments de liaison déchirables (4) à une plaque (6) pouvant être fixée sur le collet (3). Au moins deux éléments de liaison (4) mènent du bouchon (1) en biais vers le bas à la plaque commune (6). En vue de dessus, elles s'écartent dans le sens antihoraire de la radiale R qui mène centralement aux éléments de liaison (4). Lors de la première ouverture, les éléments de liaison (4) sont étirées, de sorte qu'elles ne pivotent ensuite plus en retour dans leur position initiale, mais qu'elles pivotent en retour dans une position en dessous du bord inférieur du bouchon vissé (1).
