Abstract
A combination dustpan and trapdoor receptacle closure having a handle and hinge means to allow pivotal mounting on the receptacle such that removal of the closure from the receptacle isn't necessary in order to deposit refuse in the receptacle and such that the hands need not come into direct contact with the possibly soiled closure surface in order to access the inside of the receptacle, said closure further characterized by a spade-like edge to aid in the movement of refuse toward the central area of the closure when said closure is removed from the receptacle and used as a dustpan.
