CA 2167602

Closure caps with anti-tamper strips (3) are used to visually display initial opening of a container to the public. The possibility of opening such a container without evidence should be prevented as far as possible. The possibility of stretching the anti-tamper strip (3), in order to then manipulate it past the bead on the container mouth, is here countered by an additional security ring (7). This security ring (7) is arranged coaxially to the actual anti-tamper ring (3). It is connected to the anti-tamper ring and mainly surrounds the lower area (5) of said anti-tamper ring. Access to the actual anti-tamper ring is considerably hindered as a result. In a preferred embodiment, the security ring possesses weakened zones (10) that break during manipulation, so that the interference will be visibly displayed to the outside.

Des bouchons de fermeture à bande de garantie (3) sont utilisés en vue d'indiquer à tout utilisateur la première ouverture d'un récipient. Il s'agit d'exclure, dans la plus large mesure, tout risque que l'ouverture d'un tel récipient passe inaperçue. La possibilité d'étirer la bande de garantie (3), en vue de la manipuler au-dessus de la protubérance de l'ouverture du récipient, est ici écartée grâce à la présence d'une bague d'arrêt supplémentaire (7). Celle-ci est disposée coaxialement à la bague de garantie proprement dite (3). Elle est reliée à la bague de garantie et entoure initialement sa partie inférieure (5), ce qui complique notablement l'accès à la bague de garantie proprement dite (3). Dans une forme d'exécution préférée, la bague d'arrêt présente des zones de moindre résistance (10) qui se déchirent lors de toute tentative de manipulation, de sorte que toute intervention extérieure se trouve ainsi décelée.
