  • the present invention relates to a plastic closure consisting of a lower part and a cover connected thereto via a hinge axis, as well as an integrity guarantee element.
  • Integrity guarantee elements on plastic hinge locks have been known for many years. They are intended to offer a high level of security for the consumer by making the integrity of the closure and thus the contents in the container protected by the closure visible. A large number of different variants are known for this. Most closures, especially on plastic containers, are so-called bounced and can practically not be removed from the container without being destroyed. With such closures, however, it must also be ensured that the lid has not already been opened before first use and that part of the contents have thus been removed or third-party substances have been added. Such integrity elements were most often implemented in the form of guarantee bands. From US-A-4 '487' 324 (Ostrowsky) a plastic closure of the type mentioned at the outset with a guarantee of integrity element is known.
  • a tamper-evident guarantee element here is a guarantee band which is attached in one piece to the lower part of the closure and extends over more than half the circumference and is connected to the lower part via predetermined breaking points.
  • the cover which is movably arranged on the lower part by means of a swivel hinge, has various cam-like projections all around, which engage under the guarantee band between the predetermined breaking points.
  • the main problem of such and similar guarantee elements is that the guarantee band is often destroyed when it is closed for the first time. The result was a high reject rate and fully automatic closing of such closures could only be achieved with very high cycle times. The economy was practically lost.
  • plastic hinge locks For example, a trend can be identified that makes two-tone closures desirable. This calls for so-called two-component injection molding machines, which are extremely expensive and for which there are still relatively few possible uses. It is therefore the object of the present invention to provide a swivel hinge closure made of plastic according to the preamble of claim 1, which can be manufactured extremely inexpensively with simple shapes and can be injected accordingly in a short cycle without having to accept a high reject rate. It is a further object of the present invention to provide a plastic closure whose tamper-evident element can have a different color than the rest of the closure and thus has an increased individualization and an improved visual control for the consumer.

  • the structural design of the tamper-evident element 10 can be seen in more detail in FIG. It consists of an actual band 11 which has an upper contact surface 12 projecting perpendicularly from the band and a circumferential, lower flexible retaining edge 13.

Practically all known solution principles, including those that are not shown here, come into question. However, preference will always be given to solutions that do not require gluing or welding.
  • FIGS 16-19 to be described below show details of tamper-evident elements. In principle, these detailed solutions can be implemented in various embodiments of the integrity guarantee element. However, the examples shown here are shown and can be used in particular for implementation in combination with closed, annular bands.
  • Figure 16 shows a closure with tamper-evident element 10 approximately according to an embodiment as shown in Figures 1-3.
  • the band 11 is fitted snugly over the closure and has a window 160 through which, for example, pusher parts on the lower part and cover 2, 3 pass.
  • a separating strip 161 runs all around in the longitudinal direction, which is delimited on both sides by predetermined separating points or predetermined separating seams. This can be clearly seen in the vertical section according to FIG. 17.
  • a tab 14 is formed on at least one side of this separating strip 161. By pulling this tab 14, the separating strip 161 can be torn out and the band 11 irreversibly disintegrates into two sub-bands.
  • Such a band 11 can be subjected to a relatively high tensile load without the predetermined breaking points 162 thereby being affected. Accordingly, the band 11 can perceive not only a form-fitting but also a force-fitting component in the integrity guarantee position.
  • these predetermined separation points or lines can also run perpendicular or inclined to the longitudinal direction of the band 11. This possibility is shown purely for example in FIG. 18.
  • the predetermined separation points 17 are inclined to the longitudinal direction of the band 11.
  • closed tamper-evident elements With closed, ring-shaped tamper-evident elements, the problem with various plastics is that the tensile elasticity is relatively low. This applies in particular to most polypropylenes, which are very common in closure technology.
  • closed tamper-evident elements such as bands 11 designed in the form of a ring, which, in particular, can also hold non-positively on a closure, the band 11 must have at least one stretchable region.
  • stretchable or stretchable areas can be achieved by meandering partial areas or by stretching with a large number of openings, so that these openings can spread under tension.
  • Such a band section which is designated as a whole by 190, is shown in FIG. 19a.
  • a plurality of expandable openings 191 are present within this stretchable band area. These expandable openings 191 open under tension, as can be seen in FIG. 19b.
  • the stretchable or stretchable Band area 190 is delimited by predetermined breaking lines 17.
  • a tab 14 is attached to the lateral ends of the stretchable band section via bendable, bow-shaped webs 192. By pulling the tab 14, the predetermined breaking points 17 perpendicular to the direction of the band 11 can be separated without any problems. Because there are small webs in the band direction in the area of the predetermined breaking points, with a very small cross-section, the molecular chains are aligned in this area and accordingly these webs withstand relatively high tensile forces in the direction of the webs or the molecular chains. By pulling on the tab 14, however, a force is exerted perpendicularly to this direction, which causes a notch effect on the molecular chains and accordingly the predetermined breaking points can be easily separated.
  • the variant of an integrity guarantee element with a stretchable or stretchable area can also be combined with clasp-shaped elements which are held under prestress on the lower part and cap.
  • closures can no longer be brought into the first closed position in one operation, but require a separate assembly machine for this purpose; because, on the other hand, the injection molds are considerably cheaper, they do not have to have any complicated closing mechanisms and because the thin points for the predetermined breaking points on the closure itself are eliminated, the cycle time per injection process can be reduced considerably.
  • the assembly machines themselves normally allow such high productivity that a single assembly machine is sufficient to process the production of several injection molding machines.
  • the integrity guarantee elements according to the invention can also be made particularly large. This gives them an increased signal effect. This signal effect can be extremely emphasized by the fact that the security guarantee element can easily be made in a different color or from a different material than the closure. Without the expensive purchase of a two-component injection molding machine, a two-tone plastic closure can be achieved that can meet the highest aesthetic requirements.

Abstract

L'invention concerne des fermetures en matière plastique (1) présentant une base (2) et un couvercle (3) réalisé d'une seule pièce avec cette base, via une charnière (4) et pour lesquelles l'élément d'inviolabilité (10) était jusqu'à présent formé directement sur un élément de fermeture. L'invention vise à ce qu'une opération distincte dans la fabrication de l'élément d'inviolabilité (10) soit réalisée à bien moindre frais et soit plus économique, en dépit d'une phase supplémentaire dans la fabrication. A cet effet, l'invention est caractérisée en ce que l'élément d'inviolabilité (10) est constitué par une bande (11) annulaire ou en forme de boucle, ouverte ou fermée, qui, par l'intermédiaire de moyens de serrage (12, 13) assure le maintien, par liaison de forme et/ou par liaison par adhérence, aux deux éléments de fermeture, à savoir, la base et le couvercle.
