Abstract

Apparatus for locking a top of a case having an unlocked closing flap and L-slide lock slots for receiving opposite free end corners of the closing flap includes a closing flap securing device which provides a source of suction for detachably securing a top surface of a generally horizontal unlocked closing flap of a stationary case. Movement of the securing device from a generally horizontal position to a generally inclined position while secured to the closing flap first forms a longitudinal fold in the closing flap and positions the opposite free end corners of the closing flap adjacent respective L-slide lock slots. Subsequent movement of the securing device from the generally inclined position to the generally horizontal position then flattens the longitudinal fold and tucks the opposite free end corners of the closing flap into the respective L-slide lock slots to thereby lock the case. Suction from the closing flap securing device is then terminated to detach the securing device from the top surface of the closing flap of the case.
