Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
149 words
In a disposable diaper having a top sheet, a backing sheet and an absorbent core interposed therebetween, a means for providing self-stored protective access to a portion of the adhesive surface of a diaper tape fastener comprising, a pressure-sensitive tape fastener having an upper surface and a lower surface, said lower surface being divided widthwise into two end segments at least one of which is adhesively treated and a middle segment containing a release agent, one of said end segments being a fixed end segment which is secured to said backsheet, the other of said end segments being a releasable end segment; said fastener being folded in manner such that said releasable end segment and said middle segment are superimposed over said fixed end segment with the lower surface of said releasable end segment being in contacting relation and releasably secured to the lower surface of said middle segment.
Claim 2
Dependent Claim
149 words
In a disposable diaper having a top sheet, a backing sheet and an absorbent core interposed therebetween, a means for providing self-stored protective access to a portion of the adhesive surface of a diaper tape fastener comprising, a pressure-sensitive tape fastener having an upper surface and a lower surface, said lower surface being divided widthwise into two end segments at least one of which is adhesively treated and a middle segment containing a release agent, one of said end segments being a fixed end segment which is secured to said backsheet, the other of said end segments being a releasable end segment; said fastener being folded in manner such that said releasable end segment and said middle segment are superimposed over said fixed end segment with the lower surface of said releasable end segment being in contacting relation and releasably secured to the lower surface of said middle segment.
Claim 3
Dependent Claim
