Abstract: A key operated security cap structure for a container, such as a medicine bottle, having a neck defining an opening for the container comprises a cap member for fitting over the neck of the container in a manner precluding removal of the cap member during normal usage of the container, the cap member having an internally threaded cylindrical portion extending above the rim of the container, a cylindrical externally threaded plug for threading into the cap member to a terminal position wherein the outer surface of the plug is substantially flush with the rim of the cap member, the outer surface of the plug being formed with a pair of diametrically spaced key-receiving recesses, and a key having a pair of projections fitting in the plug recesses to provide a means for removing the plug and opening the container.

Abstract: A striker plate attached to the door frame or door jamb associated with a door provided with a dead bolt lock of the type having vertically reciprocating bolts received in aligned apertures in a pair of lugs attached to the strike plate. In the present invention, the strike plate is provided with lugs having a larger than normal area and which project inwardly of the body of the lock and have a second pair of aligned apertures for receiving a security pin so that when the security pin is in position, the door cannot be opened even if the lock bolts are retracted. In addition, the lugs have a third pair of aligned apertures receiving the security pin which has a safety chain or cable attached thereto and anchored to the lock or door so that the door can be opened a limited distance when the lock bolts are retracted thereby enabling an occupant to safely open the door a limited amount in order to determine whether the door should be completely opened or not.
