ABSTRACT:
Child-resistant locking means for a container and a cap therefor. The container has a tubular neck and the cap has a circular top and an annular skirt. The container neck and cap have interengageable threads for retaining the cap on the closure. The child-resistant locking means consist of an outwardly extending stop on the container neck and a cap lug engageable therewith to normally prevent retrograde rotation of the cap. The cap lug is located on a curved, resilient, web-like member which extends around the base of the cap and which has outwardly extending struts to space it from the cap. The cap lug is located about 45.degree. from one of the struts. In the preferred embodiment the resilient member is a complete ring, either circular or oval or a similar shape. Squeezing the resilient member inwardly along a diameter spaced about 45.degree. from the cap lug bulges the member outwardly at the lug so that the lug clears the container stop when the cap is rotated for removal.
