CA 2580545

A tamper-indicating child-resistant package includes a container (14) having a finish (18) with an open mouth (20) and an external circumferential bead (26) spaced from the mouth. A closure (12) has a skirt (30) for externally encircling the container finish, a tamper band (36) frangibly connected to the skirt for positioning beneath the external circumferential bead on the container finish, and a spring element (42) for engaging the finish and biasing the closure away from the finish. The finish and the skirt have interlocking elements (22,24,32,34) that resist removal of the closure from the finish absent force against the spring element to disengage the interlocking elements. Engagement of the tamper band with the external circumferential bead ruptures the frangible connection of the band to the skirt upon first removal of the closure from the container finish to indicate potential tampering with the package.

Cette invention concerne un conditionnement inviolable à l~épreuve des enfants qui comprend un récipient (14) doté d~une bague (18) avec un goulot ouvert (20) et un bourrelet circonférentiel externe (26) espacé du goulot. Un bouchon (12) comprend une jupe (30) pour encercler extérieurement la bague du récipient, une bande inviolable (36) cassable reliée à la jupe pour se positionner sous le bourrelet circonférentiel externe sur la bague du récipient, et un élément à ressort (42) permettant d~engager la bague et d~incliner le bouchon à distance de la bague. La bague et la jupe ont des éléments de verrouillage (22, 24, 32, 34) qui s~opposent au retrait du bouchon par rapport à la force manquante de la bague contre l~élément à ressort pour désengager les éléments de verrouillage. L~engagement de la bande inviolable avec le bourrelet circonférentiel externe rompt la connexion cassable de la bande sur la jupe lors du premier retrait du bouchon de la bague du récipient pour indiquer une tentative d~ouverture du conditionnement.
