Abstract
Abstract A disposable diaper is provided with a release region on the diaper outside surface spaced inwardly from the longitudinal margins of the diaper. At least one tape segment having an adhesive-coated face is releasably parked on the release region, and is completely removable therefrom for securing the diaper about an infant. A plurality of tape segments may be releasably parked on the release region so that after securement the diaper can be removed from the infant and thereafter refastened thereon by means of subsequent tape segments. One or more release regions may be provided. Preferably, two release regions are provided spaced inwardly from opposite longitudinal margins of the diaper, with at least two tape segmens being releasably parked on each release region.

Claim 1
Independent Claim
158 words
A disposable diaper having a facing sheet defining a diaper inside surface for direction toward an infant, a moisture-impervious 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 adhesive tab fastener means comprising: a release region on the diaper outside surface spaced inwardly from the margins of said diaper; at least one tape segment releasably parked on said release region, said tape segment having a pressure-sensitive adhesive coating on one face thereof which is releasably attached to said release region, each tape segment being positioned on said release region in its entirety inwardly from the margins of said diaper; each said tape segment being removable from said release region and from said diaper in its entirety to make the entire adhesive-coated area thereof available for attachment to any desired position on said diaper for securing said diaper about an infant.
Claim 2
Dependent Claim
158 words
A disposable diaper having a facing sheet defining a diaper inside surface for direction toward an infant, a moisture-impervious 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 adhesive tab fastener means comprising: a release region on the diaper outside surface spaced inwardly from the margins of said diaper; at least one tape segment releasably parked on said release region, said tape segment having a pressure-sensitive adhesive coating on one face thereof which is releasably attached to said release region, each tape segment being positioned on said release region in its entirety inwardly from the margins of said diaper; each said tape segment being removable from said release region and from said diaper in its entirety to make the entire adhesive-coated area thereof available for attachment to any desired position on said diaper for securing said diaper about an infant.
Claim 3
Dependent Claim
27 words
The disposable diaper as defined in claim 1 wherein at least two relase regions are provided and are spaced inwardly from opposite longitudinal margins of said diaper.
Claim 4
Dependent Claim
40 words
The disposable diaper as defined in claim 1 wherein two release regions are provided near opposite corners of said diaper at the same transverse end thereof, and wherein at least two tape segments are releasably parked on each release region.
Claim 5
Dependent Claim
57 words
The disposable diaper as defined in claim 1 wherein at least one tape segment having two opposed faces is attached at one face directly to said release region and has a release coating on the unattached face thereof, and wherein at least one additional tape segment is releasably stacked on top of said directly attached tape segment.
Claim 6
Dependent Claim
53 words
The disposable diaper as defined in claim 4 wherein a portion of each said tape segment projects beyond the outermost edge of said adhesive coating carried thereon, whereby said projecting portion provides a gripping means for separating said tape segment from an underlying release surface preparatory to fastening said diaper about said infant.
Claim 7
Dependent Claim
44 words
The disposable diaper as defined in claim 4 wherein two release regions are provided near opposite corners of said diaper at the same transverse end thereof, and wherein at least one stack of tape segments is releasably parked on each of said release regions.
Claim 8
Dependent Claim
51 words
The disposable diaper as defined in claim 1 wherein a portion of said tape segment projects beyond the outermost edge of said adhesive coating carried thereon, whereby said projecting portion provides a gripping means for separating said tape segment from said release region preparatory to fastening said diaper about said infant.
Claim 9
Dependent Claim
52 words
The disposable diaper as defined in claim 1 wherein said release region has a release surface area which is greater than the combined adhesive area on said tape segments parked thereon to facilitate gripping said tape segments for separation from said release region in preparation for fastening said diaper about said infant.

Dependent Claim
153 words
A disposable diaper having a facing sheet defining a diaper inside surface for direction toward an infant, a moisture-impervious backing sheet substantially coextensive with said facing sheet and defining a diaper outside surface, an aborbent panel positioned between said facing and said backing sheet, and adhesive tab fastener means comprising: a release region on the diaper outside surface spaced inwardly from a longitudinal margin of said diaper; a plurality of tape segments which are releasably parked on said release region, said tape segment having a pressure-sensitive adhesive coating on one face thereof which is releasably attached to said release region; a first tape segment from said plurality being removable from said release region to make the entire adhesive area of said adhesive-coated tape segment available for securing said diaper about an infant initially, and subsequent tape segments of said plurality being removable from said release region to refasten said diaper about the infant.
Claim 11
Dependent Claim
153 words
A disposable diaper having a facing sheet defining a diaper inside surface for direction toward an infant, a moisture-impervious backing sheet substantially coextensive with said facing sheet and defining a diaper outside surface, an aborbent panel positioned between said facing and said backing sheet, and adhesive tab fastener means comprising: a release region on the diaper outside surface spaced inwardly from a longitudinal margin of said diaper; a plurality of tape segments which are releasably parked on said release region, said tape segment having a pressure-sensitive adhesive coating on one face thereof which is releasably attached to said release region; a first tape segment from said plurality being removable from said release region to make the entire adhesive area of said adhesive-coated tape segment available for securing said diaper about an infant initially, and subsequent tape segments of said plurality being removable from said release region to refasten said diaper about the infant.
