Bottle opening ring having shock absorbing means

摘要

An opening ring (40) for a bottle (29) has a closure element (36) attached to the bottle neck (30) at a frangible section (38). The opening ring (40) includes rigid shock absorbing means such as a collar (58) to protect the bottle from unwanted opening of the frangible section (38) which would thereby destroy the seal, and in the case of bottle-stored sterile liquids, contaminate same.
