Abstract
Abstract A cover assembly is provided for use with a hamper of a type used in hospitals, nursing homes and for the dirty linen, trash, or the like. The hamper is of a type having a frame with an upper rim over which a removable liner which is positioned and held in an open position. The cover assembly further comprises a pair of elongated mounting brackets secured at one end to the frame at a position spaced downwardly from the upper rim. A planar lid dimensioned to fit over the open end of the liner includes a pair of elongated, spaced and parallel tracks secured to it while a slide block is slidably mounted to each track. Each slide block, in turn, is pivotally mounted to the other end of one of the elongated brackets so that the lid is both pivotally and slidably mounted to the brackets and is movable between an open and a closed position. In its closed position, the lid is positioned over the open end of the liner while, in its open position, the lid lies in a substantially vertical plane adjacent the frame.
