A cover for a trash receiving open top container which is adapted to provide a shallow sloped surface leading to an opening that is sized to a dimension that is less than the smallest dimension of a tray on which trash is usually conveyed to be deposited in the container. The cover is needed to prevent the loss of trays into the container by persons who either allow a tray to slip into the container or simply shove the tray onto the cover and leave it unemptied. The cover is provided with a strengthened opening to prevent forceful insertion of a tray and it provides other openings to quickly drain off fluids and small items of trash.
