Abstract
Abstract A disposable diaper comprising, an absorbent pad assembly having a fluid impervious backing sheet at least partially defining a back surface of the pad assembly, a front surface, a pair of side edges, a pair of end edges connecting the side edges, and a pair of waistline portions. The diaper has a disposable cover adjacent an edge of the pad assembly, the cover comprising a sheet of flexible material being transversely folded to a configuration of reduced dimensions. The sheet has a sufficient width and length to pass over remote portions of the pad assembly and provide a cover for the soiled pad assembly after use of the diaper. The diaper has means for securing side regions of the folded sheet together and retaining the secured sheet to a surface of the pad assembly to provide access to a sufficient area of the sheet for covering the diaper.
