A cover for enclosing the open top of a container, such as a liquid waste receptacle. The cover comprises an annular support dimensioned to fit generally coaxially within the open top of the container. The annular support defines an opening for passage of materials therethrough and into the container. The cover further comprises a mechanism for releasably securing the annular support to the upper edge margin of the container, a straining element in the annular support having a straining area coextensive with substantially the entire area of the opening in the annulaar support for straining solid objects of a predetermined maximum dimension from entry into the container while permitting entry of liquids through the opening and into the container, a lid dimensioned for covering the opening in the annular support, and a hinge for securing the lid to the annular support. The lid is swung on the hinge between an open position in which the lid is positioned away from the opening in the annular support to provide access to the top of the container and a closed position in which the lid completely covers the opening in the annular support and seals against the annular support to prevent materials within the container from escaping the container.

A method for disposing of liquid wastes while preventing useful articles or other solid objects from being disposed with the liquid wastes, the method comprising: providing a cover for use with a container, such as a liquid waste receptacle, having an upper edge margin defining an open top of the container, for enclosing the open top, comprising: an annular support dimensioned to fit generally coaxially within the open top of the container and defining an opening for passage of materials therethrough and into the container; means for releasably securing the annular support to the upper edge margin of the container; a straining element in the annular support having a straining area coextensive with substantially the entire area of the opening in said annular support for straining solid objects having a predetermined maximum dimension from entry into the container while permitting entry of the liquids through the opening and into the container, the straining element and the annular support in combination defining an inner surface of the cover dimensioned so that a substantial portion of the inner surface is located below the upper edge margin of the container; a lid dimensioned for covering the opening in the annular support; hinge means for securing the lid to the annular support, the lid being swingable on said hinge means between an open position in which the lid is swung away from the opening in the annular support to provide access to the top of the container and a closed position in which the lid completely covers the opening in the annular support to prevent materials within the container from scaping out of the container; and a member at the hinge engageable with the lid to hold the lid at predetermined angle; installing the cover on the open top of the container; and dispensing the liquid wastes through the straining element of the cover and into the container thereby straining solid objects having a predetermined maximum dimension from entry into container.
