Child resistant safety cap

摘要

An improved safety closure for containers is disclosed; the closure comprises a snap-on cap held in place on a container by a rotary safety ring which must be aligned with the cap in one angular position and pushed downwardly away from the cap before one can remove the cap from the container. The closure is improved by providing an outwardly directed bead on the safety ring which makes it easier to grip and push down (and up) the safety ring. An annular protrusion, added to the underside of the cap, and a circumferential knob, added to the neck of the container, improve the seal of the container. Also, a safety ring and cap assembly which has no lateral opening between the safety ring and the cap is disclosed. This invention describes various ways to incorporate on the closure means for counting the number of uses or doses of the container's contents. Finally, two specific embodiments of the closure, a closure for a powder container and a pipette dropper safety closure, are described with some of the improvements.
