Abstract: A self defense tool includes a tubular body provided with an axial bore and a removable closed handle end opposite a removable closed striking end. A variable weight holding arrangement is positioned inside the axial bore of the body between the handle and striking ends and is engageable with the striking end. The holding arrangement is adapted to retain at least one weight member inside the axial bore to selectively enable changing weight of the tool. The variable weight holding arrangement includes a stop disposed in the axial bore of the body, and a coil spring inserted in the axial bore and extending between the stop and striking end. The at least one weight member is adapted to be received in the axial bore and held between the spring and the striking end.

Abstract: A child resistant closure for a container having a threaded neck. The closure comprises a cap including a disc-shaped end wall and an internally threaded depending cylindrical side wall or skirt having an annular bottom end surface. A yieldable ledge or collar is on the neck of the container in a position to be engaged by the end surface of the cap side wall when the cap is threaded fully onto the neck of the container, and a shaped, interfitting lug and recess are on the collar and cap end surface in a position to be automatically interengaged everytime the cap is threaded fully onto the container to lock the cap in a fully closed position on the container. The collar is yieldable to enable selective release of the lug and recess to thereby enable retrograde movement of the cap from the threaded neck.
