Abstract
A one piece molded tamper evident push-on closure suitable for closing an opening of a bottle, and method for manufacture thereof. The closure includes a cap portion, a latch ring portion and a frangible connector connecting the cap portion and the latch ring portion. The closure includes a plurality of resiliently deformable teeth extending inwardly from the latch ring portion and towards the cap portion for engaging the latch ring portion onto the neck of the bottle. The closure includes a manually engageable tab projecting from the latch ring portion to permit application of a manual force to rupture the frangible connector and permit the cap portion to be at least partially disconnected from the latch ring portion.
