TAMPER EVIDENT CLOSURES

摘要

A snap-on or screw type, tamper evident closure having first and second relatively moveable plastic parts (16, 18) which move from an initial position to a new limiting position when the closure is first opened, the new limiting position being visually distinguishable from the initial position to provide the tamper evidence. The two plastics parts are formed in mutually intimate association but have inter-engaging complimentary formations (22, 28, 40, 42) which become irreversibly disengaged on first opening of the closure.
