Abstract: A drinking device that includes a receptacle for holding a liquid, a cover removably attached to the receptacle to encapsulate the liquid within the receptacle, and a locking element. The cover has a drinking opening that allows a user to access the liquid within the receptacle. The locking element is attached to one of the cover or receptacle, and configured to engage the other of the cover or receptacle. The locking element is movable between one or more locking positions for securing the cover to the receptacle, where a first locking position of the locking element secures the cover to the receptacle and prevents a user from accessing liquid through the drinking opening.

Abstract: A rekeying tool for a lock having a lock body, cylinder, upper and lower tumbler pins and upper springs, includes a cylindrically elongated follower having opposing ends. At least one of the ends is hollow and has a V-shaped or U-shaped groove. A cylindrically elongated solid piston having a corresponding V-shaped or U-shaped groove at an end is resiliently positioned in the hollow end of the follower. The solid piston includes a cut-through channel and a pin. The pin extends a cross-section of the hollow end of the follower and passing though the cut-through channel to guide reciprocating travel of the piston from an inwardmost position to an outwardmost extension. The V-shaped or U-shaped groove of the solid piston is substantially aligned with the corresponding V-shaped or U-shaped groove of the hollow end of the follower when the piston is at the outwardmost extension.

Abstract: A security replacement cam to prevent the unauthorized removal of a lock cylinder from the lock case. The lock cylinder has an activation cam rotatable by a keyed cylinder plug having a cam surface extension that engages a locking means in the locked case. Security cam replaces the original cam and has a locking mechanism cam surface and a secondary oppositely disposed security cam extension surface that extends beyond the lock cylinder when in locked position. This prevents the lock cylinder from being removed from the case thus blocking access to the lock mechanism by unauthorized users.
