ABSTRACT:
A two-piece stopper is provided for insertion into the mouth of garbage disposal units. The first piece inserts snugly into the open disposal mouth and has rather large apertures through which water can pass, when the disposal unit is not in use and the sink in which it is mounted is to be used as an ordinary sink. The apertures are large enough to pass small bits of food and waste, but small enough to keep out popsicle sticks, bottlecaps, silverware, and the like. The second piece is a plug which inserts into a cylindrical wall or bore in the first piece to cover the drain apertures of the first piece so that the sink's drain opening is entirely covered and the sink can be filled with water for washing dishes and similar purposes.
