Patent

CA 2455289

A closure (10) is provided and includes a tamper-evident band (40). The band (40) has a plurality of retaining flaps (60) which engage under a container neck annular retaining bead (23) when the closure is first applied. The flaps have a ratchet surface (86a, 190) for engaging a complimentary surface on the container neck (20). The flaps also have spacer means (85a, 85b, 186) for pushing them into a more vertical inclination under the bead (23). The ratchet arrangement and spacer means ensure reliable separation of the tamper-evident band (40).

L'invention concerne une fermeture (10) qui comprend un manchon (40) d'inviolabilité. Ledit manchon (40) est pourvu de plusieurs rabats (60) de retenue, en prise sous un bourrelet (23) de retenue annulaire du col d'un récipient lorsque la fermeture est réalisée pour la première fois. Les rabats présentent une surface d'encliquetage (86a, 190) destinée à être en prise avec une surface complémentaire sur le col (20) du récipient. Les rabats sont également pourvus de butées d'espacement (85a, 85b, 186) qui les poussent vers une inclinaison plus verticale sous le bourrelet (23). Le dispositif d'encliquetage et les butées d'espacement garantissent une séparation fiable du manchon (40) d'inviolabilité.
