ABSTRACT:
A two-piece "push and turn" child resistant closure is disclosed in which an inner cap member has a threaded connection with a vial or bottle which is capable of making a good sealing connection to protect the contents of the container against deterioration. The outer member has a series of protuberances, or a preferably square configuration which greatly improves the utility of the closure for persons having arthritis or other ailments which make it difficult to turn a round closure. Leaf spring operating spring elements are housed in the corners of the protuberances of the outer member.
