ABSTRACT:
A cap for a bottle has a top portion for covering the open mouth of the bottle and two spaced rings extending therefrom to define a groove to receive an annular lip portion of the bottle. One of the rings can be angled toward the other and be flexible such that the lip of the bottle is fully grasped and maintained in the groove. The radially outer ring of the cap is provided with a plurality of circumferentially spaced weakened areas so that when the cap is removed from the bottle the outer ring will tear at at least one of the weakened areas to identify a cap which has become unsealed from its bottle.
