CLOSURE AND CONTAINER SYSTEM AND METHOD FOR SEALING A CLOSURE ON A CONTAINER

A system includes a container including projections equi-spaced around a neck region. Each of the projections includes a cam surface, a lock surface, a ramp, and a clamping surface. The system also include a closure including a closure plane and a circumferentially depending outer skirt extending from the closure plane, a tamper-evident arrangement frangibly connected to an edge of the outer skirt opposite the closure plane, and pairs of lugs equi-spaced around an inner sidewall formed by the outer skirt and the tamper-evident arrangement. A lock lug of each pair of lugs is arranged on the tamper-evident arrangement and a sealing lug of each pair of lugs is arranged on the outer skirt. In the system, each lock lug is adapted to engage the cam surface of a corresponding projection during an initial application operation. The lock lug is adapted to engage the lock surface of the corresponding projection after the initial application operation. In the system each sealing lug is adapted to engage the ramp of the corresponding projection during the initial application operation. The sealing lug is adapted to engage the clamping surface of the corresponding projection after the initial application operation. A number of pairs of lugs may be equal to a number of projections. A method is provided for sealing a closure on a container in a tamper-evident manner using the system. A method is provided for removing a closure from a container sealed with a tamper-evident device. Système comprenant un réservoir présentant des saillies éloignées les unes des autres à égale distance autour du col de ce réservoir. Chacune de ces saillies comporte une surface de came, une surface de verrouillage, une rampe et une surface de serrage. Ce système comprend également une fermeture possédant un plan de fermeture et une jupe extérieure périphérique s'étendant depuis le plan de fermeture, un dispositif anti-fraude accouplé de manière cassable à un bord de la jupe extérieure en face du plan de fermeture et des paires de pattes placées à égale distance les unes des autres autour d'une paroi latérale intérieure constituée par la jupe extérieure et le dispositif anti-fraude. Une patte de verrouillage de chaque paire de pattes est placée sur le dispositif anti-fraude et une patte de scellement de chaque paire de pattes est placée sur la jupe extérieure. Dans ce système, chaque patte de verrouillage est conçue pour venir en contact avec la surface de came d'une saillie correspondante pend
