Definitions

  • the invention relates to a plastic closure cap according to the preamble of claim 1.
  • a disadvantage of such known arrangements is that the guarantee bands connected at one point to the cap wall no longer lie against the bottle neck, but protrude outwards when they are no longer completely connected to the closure cap. These protruding bands are particularly disadvantageous in the washing and refilling process of reusable containers. When returning these containers, the caps are placed on the container. If the containers are machined further, there is Danger of containers standing side by side interlocking with the protruding guarantee bands. Since the guarantee tapes must have a relatively high strength so that they reliably tear and do not expand when the closure is removed for the first time, the containers hooked on the guarantee tapes cannot detach from one another. The result is that the hooked containers fall over and cause a malfunction of the processing system or the conveyor belts.
  • the object of the invention is to avoid the disadvantages of the known, in particular to create a closure cap for closing a refillable container, which reliably avoids the jamming of protruding guarantee tapes of two containers standing next to one another.
  • a plastic closure cap for closing a container essentially consists of a cap base and a cap wall attached to the outer edge of the cap base.
  • the inside of the cap wall has retaining elements, for example a screw thread, with which the closure cap can be attached to the neck of a container, for example a beverage bottle.
  • the closure cap also has a guarantee band attached to the lower edge of the cap wall.
  • the inside of the guarantee band has retaining elements which, when the closure cap is attached, interact with retaining means on the outside of the container mouth.
  • the guarantee band is at least partially connected to predetermined breaking points with the lower edge of the cap wall. So that the guarantee band does not remain on the container mouth when the closure is removed, it is firmly attached to at least one growth point connected to the cap wall.
  • the guarantee band according to the invention has at least two joints arranged approximately parallel to the axis of the closure. Thanks to these joints, the guarantee band as a whole is less elastic and it is divided into several short, self-elastic individual segments that are easy to move against each other. When the closure is opened for the first time, the guarantee band is partially separated from the cap wall. Juxtaposed containers with caps with outward-facing guarantee bands can no longer get caught in one another with such a construction. Thanks to the joints, the guarantee bands are designed to be so flexible that the bottles can easily be detached from one another.
  • the guarantee band has at least two, advantageously three joints, which are distributed approximately at regular intervals over the circumference of the guarantee band.
  • a particularly simple construction principle results if the joints are designed as material weaknesses in the guarantee band.
  • These material weakenings can be applied both on the inside and on the outside of the band.
  • An arrangement on the outside promotes flexibility in particular.
  • a weakening of material on the inside and outside leads to particularly flexible guarantee bands.
  • Foldable barbs are preferably used as retaining elements on the inside of the guarantee band.
  • the use of a plurality of barbs which are connected to one another is particularly favorable. In this case it is advantageous to arrange the joints between two barbs and not to connect these barbs together. In this way, the flexibility of the guarantee band is additionally increased.
  • the guarantee tape is firmly attached to the cap wall in a growth point.
  • a vertical predetermined breaking line is arranged on one side immediately adjacent to this growth point, which enables the tamper-evident band to be torn open when the closure cap is removed from the container for the first time.
  • a joint is arranged adjacent to the other side of the growth site.
  • FIG. 1 bottom view of a guarantee band of a closure cap according to the invention
  • FIG. 2 cross section through a closure cap according to the invention
  • FIG. 3 three-dimensional representation of the closure cap from FIG. 2,
  • FIG. 1 shows the bottom view of a closure cap 1, which consists of a base 2 and a cap wall 4 fastened to the outer edge of the base 2.
  • a guarantee band 8 is attached at the lower edge of the cap wall 4.
  • the guarantee band 8 is partly detachably connected to predetermined breaking bars 14 and partly fixedly to an enlargement point 13 with the cap wall 4.
  • the guarantee band has four joints 9.
  • the joints 9 are designed as a thinner material on the outside of the guarantee band. They are distributed over the circumference of the guarantee band 8.
  • a joint 9 is arranged adjacent to the growth point 13.
  • On the other side of the A vertical predetermined breaking line 15 is provided at the growth point 13.
  • the guarantee band 8 tears in the area of the predetermined breaking line 15 and detaches from the cap wall 4 at the predetermined breaking webs 14. However, the guarantee band 8 remains connected to the cap wall 4 at the growth point 13. Thanks to the joints 9, however, the guarantee band now detached from the closure cap has great mobility.
  • FIG. 2 shows a cross section through a closure cap 1 according to the invention.
  • Retaining means 5 are provided on the inside of the cap wall 4, by means of which the closure cap 1 can be attached to a container.
  • the guarantee band 8 attached to the lower edge of the cap wall 4 has retaining means 16 on its inside, which cooperate with retaining elements on the outside of the container.
  • the guarantee band can be detached by means of predetermined breaking bars 14 and is firmly connected to the cap wall 4 by means of a growth point 13. Adjacent to the growth point 13 are a vertical predetermined breaking line 15 on one side and a joint 9 on the other side.
  • the restraining means 16 can also have an interruption 17 in the region of the joint 9.
  • FIG. 3 shows a closure cap 1 unscrewed from a container.
  • the guarantee band 8 is separated from the cap wall 4 in the region of the predetermined breaking webs 14 and is only connected to it via the growth point 13.
  • a first joint 9 is located directly adjacent to the growth point 13. Further joints 9 are distributed uniformly over the circumference of the guarantee band 8.
  • the guarantee band is thereby divided into five individual segments which are relatively freely movable with respect to one another.
  • the joint 9 can be formed by a material recess 10 on the outside of the guarantee band. There is a continuous walking retention element.
  • the joint 9 is formed by a recess lying on the inside of the guarantee band 8.
  • the restraining means 16 have an interruption 17 in the area of the joint 9.
  • the restraining means 16 consist of individual barbs, as in FIG. 6, it is advisable to arrange the joints 9 in each case between two adjacent barbs.
  • the barbs are preferably connected to one another and provided with an interruption 17 only in the area of the joints 9.

Abstract

L'invention concerne un bouchon de fermeture (1) garantissant l'inviolabilité, présentant un fond (2), une paroi (4) et une bande de garantie d'inviolabilité (8) fixée au bord inférieur de la paroi (4). Cette bande (8) est raccordée à la paroi (4) au moyen de nervures (14) destinées à la rupture et d'un point d'attache (13). Afin d'accroître la flexibilité de la bande (8), plusieurs articulations (9) s'étendant pratiquement parallèlement à l'axe de vissage du bouchon de fermeture (1) sont placées dans le sens périphérique de la bande (8).
