Abstract

The hole punch has a punch bottom part (10), provided with bent down side edges (12), and a waste receptacle (14) which is detachably fixed to the punch bottom part from below. The waste receptacle (14), composed of flexible plastic material, can swing down, at its rear part (24), away from the punch bottom part (10) about a neutral axis (22) parallel to the front edge (20) and has side walls (16', 16'') interrupted in the region of the neutral axis (22). To avoid operating errors due to inadvertent removal of the entire waste receptacle (14) during the emptying process, the waste receptacle (14) and the punch bottom part (10) have, in the region between the neutral axis (22) and the front edge (20), a positive connection (38, 40) which is retained when the rear waste-receptacle part (24) is detached and swings down away from the punch bottom part (10). <IMAGE>
