ABSTRACT:
Child-resistant locking means for a twist-action cap for a container. The locking means has two cooperating parts. There is an abutment on the container near, but spaced radially from, the container neck and a tab on the cap which engages the abutment and prevents retrograde rotation of the cap. The tab is flexed inwardly in order to be moved past the abutment both when the cap is screwed onto the container neck and when it is desired to remove the cap from the container neck.
