CA 2497144

A container assembly (10) includes a container (12) that has an externally threaded finish portion and a retention structure (18) for preventing upward movement of a tamper evident band (38). The assembly (10) further includes a closure (28) having a body portion (32) of a base (34) and an internally threaded downwardly depending sidewall portion (36) that is sized and shaped to screw onto the container finish portion. The closure further includes a tamper evident band (38) that is frangibly connected to the sidewall portion (36) and that includes a main band portion (42) and a J-hook retention member (44). The retention member (44) includes a plurality of pleated retaining elements (46) for engaging the retention structure (18). At least one of the pleated retaining elements (46) is adapted to engage the container (12) so as to resist rotation with respect to the container. Separation of the tamper evident band (38) from the body portion (32) is better assured when the closure (28) is unscrewed from the container (12).

L'invention concerne un système de récipient (10) comprenant un récipient (12) ayant une section de goulot à filet extérieur et un structure de retenue (18) pour éviter tout mouvement ascendant de la bande d'inviolabilité (38). Ledit système (10) comprend en outre un système de bouchage (28) comportant une partie de corps (32) d'une base (34) et une section de paroi latérale (36) à filet intérieur, inclinée vers le bas, qui est dimensionnée et configurée de manière à pouvoir être vissée sur le partie de goulot du récipient. Le système de bouchage comprend en outre une bande d'inviolabilité (38) qui est reliée de manière frangible à la partie de paroi latérale (36) et qui comprend une partie de bande principale (42) et un élément de retenue à crochet en J (44). L'élément de retenue (44) comprend une pluralité d'éléments de retenue en accordéon (46), destinés à être en prise avec la structure de retenue (18). Au moins un des éléments de retenue en accordéon (46) est adapté pour entrer dans le récipient (12), de sorte à résister à la rotation par rapport audit récipient. Il est plus facile de séparer la bande d'inviolabilité (38) de la partie de corps (32) lorsque le système de bouchage (28) est dévissé du récipient (12).
