ABSTRACT:
A screen or grid adapted to be placed in close proximity to the receiving end of a trash receptacle housed within an enclosure which permits smaller dimensioned trash to pass through openings in the screen or grid but will prevent larger dimensioned reusable objects, such as food carrying trays, from being mistakenly or inadvertently disposed in the trash receptacle.
