Abstract
Abstract A community refuse receptacle including a flexible wall container secured at its open end in depending relation to the bottom surface of a cover overlying a well in the surface of the earth. The cover is provided with a central opening opened and closed by a hingedly connected lid. A pair of horizontally disposed tubular members are connected with the cover at opposing edges of the lid. The tubes receive lifting arms of a commercial waste disposal unit for lifting and inverting the container in an emptying action wherein the lid falls by gravity to an open position. Wall stabilizing, members depending from the lid, prevent collapse of the container when inverted.
