Abstract: A lockable enclosure includes a housing and a loading cartridge assembled with the housing and vertically slidable between a secured position in which a recess of the loading cartridge cannot be accessed through a bottom opening of the housing, and an access position in which at least a portion of the recess extends through at least a portion of the opening, such that a storable item may be withdrawn from the recess. A locking mechanism is assembled with the housing and configured to secure the loading cartridge in the secured position in a locked condition and to release the loading cartridge in an unlocked condition for downward vertical movement from the secured position to the access position. A lock interface assembled with the housing is configured to move the locking mechanism from the locked condition to the unlocked condition in response to proper user manipulation of the lock interface.
