ABSTRACT:
A tamper indicating child resistant closure for containers of two pieces in the form of a pair of telescoped caps. Opening movement requires deformation of the outer cap relative to the inner cap. Such deformation acts to break away an indicator element formed integrally with the outer cap to form an opening giving evidence that the closure has been put in condition for opening.
