Abstract: A safety closure for a container is disclosed. The container has a threaded neck, a shoulder, and one or more lug recesses and preceding camming surfaces on the periphery of the shoulder. The cap has an internally threaded inner wall and an outer, flexible, spaced concentric skirt. The skirt has one or more downwardly protruding lugs on its lower edge. Rotation of the cap relative to the bottle causes the lug to engage a camming surface. Continued rotation of the cap leads the lug into the lug recess, releasably locking the cap upon the container neck. The cap is removed by first applying an inward squeezing force to the cap skirt thereby flexing the lug outwardly to disengage the lug from the lug recess after which the cap can be rotated freely in a direction to unscrew the cap. In another embodiment, the container neck and cap have one or more partial threads so that the cap is thrust onto the neck which also cams the lug or lugs outwardly and then the cap is turned through only a partial revolution to engage the threads and move the lug into the recess.
