Abstract: A cover for open topped trash bins. The cover is fabricated of a high strength resilient polymer sheet material, such as ABS, CYCOLAC, or LUSTRAN and is formed with a central section reinforced by deformations and a generally planar peripheral section. The peripheral section is proportioned for abutting engagement with the upper edges of the open top of a bin with which the cover is used. A hinge is integrally jointed to one edge of the cover to provide for mounting of the cover on a bin and select pivotal movement of the cover between open and closed conditions relative to the top of the bin.
