Title
(EN) FOIL LINED SNAP-ON, SCREW-OFF CLOSURE
(FR) FERMETURE A PRESSION DEVISSABLE A OPERCULE
Abstract
(EN)
A tamper-evident, snap-on, screw-off closure (21) which is used with a specially shaped container neck (22) is provided with a foil liner (78). Once the closure (21) is applied to the neck (22), the foil liner (78) is sealed to the neck (22) of the container. The foil liner (78) includes a tab (80) for removal of the seal disc (78) from the neck (22). The closure (21) is characterized by the absence of a second liner between the top (54) of the cap (21) and the foil liner (78). The closure (21), neck (22) and the foil liner (78) are formed to inhibit adherence of the tab (80) to the cap interior and the neck exterior.
(FR)
Fermeture (21) à pression dévissable, indicatrice d'effraction, utilisée avec un goulot (22) de contenant spécialement conçu à cet effet, et pourvue d'un opercule (78). En appliquant la fermeture (21) sur le goulot (22) du contenant, on scelle l'opercule (78) sur celui-ci. Cet opercule (78) comprend une languette (80) servant à ôter du goulot le disque scellé (78). Cette fermeture (21) est caractérisée par l'absence d'un second opercule entre le sommet du bouchon (21) et ledit opercule (78). La fermeture (21), le goulot (22) ainsi que l'opercule (78) sont formés de manière à empêcher la languette (80) d'adhérer sur l'intérieur du bouchon et l'extérieur du goulot.
