Abstract
Abstract A protective cover for bedpans or the like comprises two sheets of paper, each waterproofed on one face with polyethylene. The sheets are superimposed one upon the other, waterproofed sides together, and the edges of the sheets are bonded together along a major portion of their perimeter. The unbonded portion of the perimeter of the sheets is of a size sufficient to extend over the edges surrounding the opening of a bedpan or the like. Elasticized thread is stitched to the edges of the unbonded portion of the perimeter for fitting and securing the cover over the external walls of the receiver and temporarily securing the sheets against motion with respect to the bedpan. A band of pressure sensitive adhesive is affixed to at least one sheet adjacent to the unbonded portion of the perimeter of the sheet for sealing the sheets together after use, thereby confining and retaining the dejecta within the protective cover.
