Abstract
A child resistant closure or cap for use on a container having a threaded, shouldered neck is disclosed. Complimentary locking means on the cap and container shoulder and a resilient release tab are provided. In one embodiment the cap includes an internally threaded cylindrically-shaped skirt having a radially extending flange portion at a bottom edge. The container shoulder has a recess formed therein and is adapted to be adjacent the cap flange portion when the cap is fully threaded onto the container neck. A downwardly extending protrusion is formed on a bottom surface of the flange portion and cooperatively engages the recess when the cap is fully threaded onto the container neck to prevent rotational removal of the cap. The protrusion is located on the resilient release tab which is formed by a circumferential slit and a perpendicular slit, whereby the release tab is upwardly or axially deflectable to disengage the protrusion from the recess and permit rotational removal of the cap. In another embodiment, the cap has a lower edge in which a release tab is arranged to be operated radially for engagement and release.
