ABSTRACT:
The disclosure herein describes the combination of a closure and a container where a frangible element is provided on the peripheral skirt portion of the closure to come into a locking engagement with the upper flange of the container. The element is made of frangible material so that it must be broken whenever the closure is removed from the container to thereby provide a visual indication of removal of the closure, whether authorized or unauthorized.
