Patent

CA 2717195

The invention relates to a tamperproof seal for a container or a syringe, with a lockable conical adapter which is sealed in a sterile manner by means of a rubber stopper and is protected by a safety sleeve, wherein the safety sleeve, which is pushed non-releasably onto the conical adapter lock, comprises a retaining part, a break-off part and a break-off zone located between said parts. The break-off part encloses the rubber stopper without radical contact. It has a retaining pin, the free end of which rests axially on the rubber stopper - when the tamperproof seal is fitted, and it has at least two open apertures. The length of the break-off part corresponds to at least twice the length of the internal thread of the conical adapter lock. The present invention produces a tamperproof seal which ensures safe handling of the combination comprising the container or syringe and tamperproof seal.

L'invention concerne une fermeture inviolable pour un récipient ou une seringue avec un adaptateur conique verrouillable, qui est fermé de façon stérile au moyen d'un bouchon de caoutchouc (40) et est bloqué par l'intermédiaire d'une douille de sécurité, la douille de sécurité poussée de façon indétachable sur le dispositif de verrouillage de l'adaptateur conique se composant d'une partie de retenue, d'une partie de rupture (81) et d'une zone de rupture placée entre ces deux parties. La partie de rupture entoure le bouchon en caoutchouc sans contact radial. Elle présente une goupille de retenue (93), dont l'extrémité libre - dans le cas de la fermeture inviolable montée - porte axialement sur le bouchon en caoutchouc et elle dispose d'au moins deux percées ouvertes. La longueur de la partie de rupture correspond au moins au double de la longueur du taraudage du dispositif de verrouillage de l'adaptateur conique. Avec la présente invention, est formée une fermeture inviolable qui garantit une manipulation sûre de la combinaison d'un récipient ou d'une seringue et d'une fermeture inviolable.
