ABSTRACT:
A tamper indicating closure assembly for a removable closure cap includes a removable overcap which completely surrounds the closure cap, the overcap having a transparent window, and a rupturable membrane intermediate the closure cap and the overcap being exposed through the window. One portion of the membrane is secured to the closure cap and another portion thereof is secured to the overcap so that relative movement between the overcap and the closure cap causes an unsecured portion of the membrane to tear.
