Abstract
Abstract A disposable diaper having a moisture-impermeable backing sheet and an absorbent pad suspended on the backing sheet is provided with a fastening tab means attached at one end to the backing sheet near one edge of the diaper. A terminal free portion of the fastening tab means extends inwardly from the diaper edge and lies substantially flat against the inside surface of the diaper, and an intermediate portion of the fastening tab means is doubled over on itself to form a relatively small section having two tab thicknesses outside the perimetric limits of the diaper.
