ABSTRACT:
A tamper indicating closure member for containers is disclosed having a cap member with a top wall and a peripheral skirt integral therewith. Also included is a separable band portion interconnected to the skirt by a frangible bridge element. The band portion is capable of coacting with an axially inclined ramp surface defined by a circumferential bead on the neck, thereby substantially preventing transverse movement of the closure band portion relative to the container neck.
