Abstract
A thermoplastic closure suitable for fitment to a threaded container neck is disclosed. The closure has at least one venting groove in the sidewall traversing the closure thread. A rigidifying means is provided at the point of traverse of the venting groove and the closure thread. This rigidifying means has a perpendicular height measured from the sidewall less than the perpendicular height of the closure thread also measured from the sidewall. The rigidifying means provides hoop strength to the closure sidewall.
