Abstract
A temperproof closure element integrally formed from molded synthetic material. The top cap section has a series of outwardly spaced projections which cooperate with mating inwardly spaced projections on a tear strip. A locking collar is provided with a similar series of inwardly spaced projections corresponding with mating outwardly directed projections on the same tear strip. The thickness of material along each of the set of mating projections is diminished providing a zone of reduced strength so that the tear strip can be removed prior to first use of the container containing the closure element.
