ABSTRACT:
A container or vial for medicines has a reversible internally and externally screw-threaded closure for selective engagement with internal and external screw-threads on the mouth of the container. Wedge sealing rings on the reversible closure force the coacting screw-threads of the closure and container into tight compressive engagement in either position of use of the closure so that the container is tightly closed. A group of locking teeth on the skirt of the closure cooperate with a single laterally movable tooth adjacent to the container side wall to lock the closure on the container so that it cannot be separated from the container without complex manipulation, thereby rendering the device child-proof. The movable tooth of the container is supported in spaced relation from the container side wall by a yielding bar carried by two radial support arms joined to the container.
