Abstract: A lockable closure for containers that is held in the locked condition regardless of the orientation of the container, yet is easily releasable in order to permit opening by simple techniques. The closure includes an internal housing in which a vertically movable locking member is retained, and from which a plurality of locking pins radially extend. The neck around the container opening includes pairs of opposed recesses to receive the locking pins when the locking member is in its lowered locking position. Raising of the locking member and release of the lock is accomplished by use of an exteriorly applied magnet that will attract the locking member and raise it out of engagement with the locking recesses in the container neck.
