Patent

CA 2215927

A closure (10) having a generally cylindrical tamper-evident band (11) joined by a plurality of frangible bridges (13b, 13c) and at least one extended non- frangible bridge (13a) to the free edge of a skirt (16) of the closure (10). The band (11) has a segmented internal rib (18) which engages an external retaining flange (30) of the container (29) when the closure is applied to the container. An L-shaped slot (17) extends through the side wall of the band (11), the horizontal leg (61) of which terminates directly adjacent to or under the extended non-frangible bridge (13a). A weakened frangible region (63) of the band extends from the terminating end (62) of the horizontal leg (61) axially downward to the bottom of the band (11).

Cette fermeture (10) possède un manchon d'inviolabilité (11) généralement cylindrique, joint au bord libre de la collerette (16) de la fermeture (10) par une pluralité de ponts (13b, 13c) d'arrachage, ainsi que par au moins un pont (13a) allongé, non déchirable. Le manchon (11) présente une nervure (18) interne segmentée qui entre en contact avec un rebord (30) de blocage extérieur du récipient (29) lorsque ladite fermeture est appliquée sur le récipient. Une fente (17) en forme de L s'étend à travers la paroi latérale du manchon (11), la jambe (61) horizontale du L se terminant directement au voisinage du pont (13a) allongé, non déchirable, ou sous ce dernier. Une région (63) cassable et moins solide du manchon s'étend de l'extrémité (62) de la jambe (61) horizontale, axialement en direction du bas du manchon (11).
