Abstract A disposable diaper having a facing sheet defining a diaper inside surface for direction toward an infant and a backing sheet defining a diaper outside surface is provided with adhesive tabs having a free end and a furcated fixed end which includes at least three integral anchoring legs. Each leg is provided with an adhesive coating on one face thereof. The fixed end is permanently attached by means of the adhesive coatings to the diaper facing and backing sheets, at least one leg being attached to the facing sheet and the remaining legs being attached to the backing sheet. The free end of the tab has an adhesive coating on one face thereof, is releasably attached to a release region provided on the diaper inside surface for such a purpose and is movable from a folded-over position, wherein the free end is releasably adhered to the release region, to a working position wherein the adhesive-coated free end is available for use in securing the diaper about an infant.

Claim 1
Independent Claim
204 words
A disposable diaper having a facing sheet defining a diaper inside surface for direction toward an infant, a moistureimpervious backing sheet substantially coextensive with said facing sheet and defining a diaper outside surface, an absorbent panel positioned between said facing sheet and said backing sheet, and an adhesive tab fastener means which comprises: an integral elongated tape segment attached to said diaper at a marginal location thereof, having a free working end and a furcated fixed end which includes at least three integral anchoring legs provided with an adhesive coating on one face of each said leg; a pressure-sensitive adhesive coating on one face of said free end; release means releasably attached to said adhesive coating on said free end; said furcated fixed end being permanently attached to the facing sheet and backing sheet at a marginal portion of said diaper, at least one of said anchoring legs being permanently attached to said facing sheet and the remainder of said anchoring legs being permanently attached to said backing sheet by means of said adhesive coatings; said free end being separable from said release means to make said adhesive-coated free end of said tape segment available for use in securing said diaper about an infant.
Claim 2
Dependent Claim
204 words
A disposable diaper having a facing sheet defining a diaper inside surface for direction toward an infant, a moistureimpervious backing sheet substantially coextensive with said facing sheet and defining a diaper outside surface, an absorbent panel positioned between said facing sheet and said backing sheet, and an adhesive tab fastener means which comprises: an integral elongated tape segment attached to said diaper at a marginal location thereof, having a free working end and a furcated fixed end which includes at least three integral anchoring legs provided with an adhesive coating on one face of each said leg; a pressure-sensitive adhesive coating on one face of said free end; release means releasably attached to said adhesive coating on said free end; said furcated fixed end being permanently attached to the facing sheet and backing sheet at a marginal portion of said diaper, at least one of said anchoring legs being permanently attached to said facing sheet and the remainder of said anchoring legs being permanently attached to said backing sheet by means of said adhesive coatings; said free end being separable from said release means to make said adhesive-coated free end of said tape segment available for use in securing said diaper about an infant.
Claim 3
Dependent Claim
64 words
The disposable diaper as defined in claim 1 wherein said furcated fixed end receives a marginal portion of said diaper between said anchoring legs, and wherein at least one of said anchoring legs is adhesively attached to said facing sheet on the diaper inside surface and the remainder of said anchoring legs are adhesively attached to said backing sheet on the diaper outside surface.
Claim 4
Dependent Claim
