Tamper evident closure

摘要

A closure for a container has a cap portion with screw threads to engage screw threads on the container and a tamper evident band connected to the cap by frangible bridge elements. The tamper evident band includes segments that engage a retaining flange on the container to separate the band when the closure is first removed from the container. Expansion segments on the band permit the closure to be initially installed on the container without breaking the frangible elements.
