Claim:
A container assembly comprising: a container having an open end and outwardly directed threads extending from an outer exterior wall surface of the container, and at least one opening located below the threads; a lid having a downwardly extending wall having inwardly directed threads configured to cooperate with the outwardly directed threads of the container to secure the lid relative to the container in a closed configuration; and a locking mechanism connected to the downwardly extending wall of the lid, said locking mechanism having at least one engagement member; wherein the container assembly has a locked and an unlocked configuration, and when in the locked configuration, the at least one engagement member is prevented from rotation in a first direction with the at least one engagement member prevented from turning by engaging the at least one opening in the container, at a radial location at least as radially outwardly as the threads of the container and lid and movement of the at least one engagement member a predetermined amount upwardly disengages the at least one engagement member from the at least one opening thereby transitioning the container assembly to an unlocked configuration to allow rotation in the first direction, and said engagement member is downwardly biased by a spring in contact with the lid from above to the locked configuration.
