Abstract
Abstract A disposable diaper having a moisture-impermeable backing sheet and highly absorbent moisture-retaining layer superposed on the backing sheet is provided with a pressure-sensitive adhesive surface which is presented through a cutout region within the perimetric limits of the diaper. The adhesive surface faces in the same direction as the inside surface of the diaper and when the diaper is wrapped about the torso of an infant the adhesive surface overlaps a portion of the backing sheet and adheres thereto.

Claim 1
Independent Claim
128 words
A disposable diaper of substantially quadrilateral configuration defined by longitudinal and transverse peripheral edges and having an inside surface for direction toward an infant when the diaper is worn by that infant and an outside surface for direction away from said infant, which disposable diaper comprises a thin, flexible backing sheet of substantially moistureimpermeable material, a moisture-retaining layer including a pad of a fibrous, non-woven, absorbent material superposed on said backing sheet and attached thereto, and an adhesive fastening means on the diaper and within the perimetric limits thereof; said fastening means being secured to said backing sheet and presenting through a cut-out open region in said diaper a pressure-sensitive adhesive surface contiguous to the inside surface of the diaper and spaced from the transverse peripheral edges thereof.
Claim 2
Dependent Claim
128 words
A disposable diaper of substantially quadrilateral configuration defined by longitudinal and transverse peripheral edges and having an inside surface for direction toward an infant when the diaper is worn by that infant and an outside surface for direction away from said infant, which disposable diaper comprises a thin, flexible backing sheet of substantially moistureimpermeable material, a moisture-retaining layer including a pad of a fibrous, non-woven, absorbent material superposed on said backing sheet and attached thereto, and an adhesive fastening means on the diaper and within the perimetric limits thereof; said fastening means being secured to said backing sheet and presenting through a cut-out open region in said diaper a pressure-sensitive adhesive surface contiguous to the inside surface of the diaper and spaced from the transverse peripheral edges thereof.
