CA 2216632

A compression failure resistant tamper evident bottle cap includes a skirt (14) with a lower edge, and a tamper-evident band (24) formed integrally with the skirt and having structure for engaging beneath a retaining flange (30) on the bottle so as to prevent subsequent withdrawal of the band. Frangible bridges (26) connect the band to the lower edge of the skirt. To prevent destruction of the bridges as the cap is forced onto the bottle during installation, the skirt has one or more tabs (32) or the like, extending downward over a portion of the band, for preventing undue diametral expansion of the tamper evident band as it passes over the retaining flange.

Un capuchon de bouteille inviolable capable de résister à une rupture par compression comprend une jupe (14) avec un bord inférieur et une bande d'inviolabilité (24) faisant partie intégrante de la jupe et ayant une structure venant en appui sous une bride de retenue (30) sur la bouteille, pour prévenir tout enlèvement ultérieur de la bande. Des ponts cassables (26) relient la bande au bord inférieur de la jupe. Pour éviter la destruction des ponts lorsque le capuchon est poussé en position sur la bouteille, la jupe a une ou plusieurs languettes ou similaire (32) qui descendent et recouvrent une portion de la bande, pour empêcher une expansion diamétrale indésirable de la bande d'inviolabilité lorsqu'elle passe au-dessus de la bride de retenue.
