Abstract
A waste receptacle (10) includes a base container portion (12) having an open top (24) defined by an upper lip (39) and a cover (11) for closing the open top (24) of the base container portion (12). The cover (11) has a downturned flange (16) having an outer peripheral groove (17) therein which forms an inner lug (18). A locking handle assembly (30) is pivotally attached to the rear wall (21) of the base container portion (12). A hook member (40) is formed on the lip (39) on the top of the front wall (20) of the base container portion (12) to form a recess (44) therebelow. The lug (18) of cover (11) is received in the recess (44). The handle assembly (30) includes lobe projections (36) which are received in the groove (17) when the handle assembly (30) is rotated toward the base container portion (12 ) at which time the locking tooth projections (38) engage the rear wall (21) of the base container (12) to lock the cover (11) in place.
