ABSTRACT:
A substantially leak-proof and child-resistant combination closure comprising a container and a cap. The container has a neck and the cap has a tubular skirt which fits over the container neck, a disc-like top and resilient annular shoulder portion. The cap skirt and bottle neck have cooperating means for retaining the cap on the container. There is a sealing liner beneath the top of the cap which engages and seals the open end of the container neck. The cap skirt and the container in some embodiments have cooperating locking means which are engaged when the cap is moved down to normal closed position on the bottle neck. The locking means function to render the closure child-resistant. Other embodiments have tamper indicating means. The resilient shoulder portion of the cap flexes to compensate for tolerance variations in the cooperating retaining means on the cap and container neck in order to insure that the cap liner seals the neck of the container.
