Abstract

A container closure assembly is disclosed including a tamper evident ring. The ring is initially substantially concealed by the closure when the closure is first fitted to the neck of the container. After the occasion on which the closure is first removed from the container neck, the tamper evident ring remains substantially visible on the container neck when the closure is replaced on the neck. The closure may include a recess for receiving the ring to conceal the ring, and releasable holding means for retaining the ring in the recess until the closure is removed for the first time. The ring may be slidably retained on a portion of the container neck.
