Abstract
Abstract A disposable garment or diaper (10) including a laminate and a hook and loop fastener for fastening together portions of the laminate (11) to secure the diaper to an individual. The fastener includes a loop fastener (15) portion adjacent a first end of the laminate comprising a multiplicity of loops, a pair of flexible elongate polymeric tab assemblies (20) having first end portions (21) attached at opposite sides to the laminate adjacent a second end (22) of the laminate (11) and having distal end portions (23) unattached to the laminate, and hook fastener portions (24) at the distal end portions of the tab assemblies comprising a plurality of projecting hook members adapted to make releasable engagement with the loops. The tab assemblies (20) include a layer (27) of pressure sensitive adhesive on the distal end portions adjacent the hook fastener portion providing, after the diaper has been soiled and removed from the individual, means (30) for securing the soiled diaper in a rolled or folded condition surrounding the soiled portion of the diaper to facilitate its disposal by engagement of the layer of pressure sensitive adhesive with the laminate.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
186 words
A disposable garment or diaper including a laminate having first and second opposite ends, and hook and loop fastener means for fastening together portions of said laminate to secure said diaper to an individual, said fastener means including loop fastener portion means adjacent the first end of said laminate comprising a multiplicity of loops, a pair of flexible elongate polymeric tab assemblies having first end portions attached at opposite sides to said laminate adjacent the second end of said laminate and having distal end portions unattached to said laminate, and hook fastener portion means at the distal end portions of said tab assemblies comprising a plurality of projecting hook members adapted to make releasable engagement with said loops, said tab assemblies including a layer of pressure sensitive adhesive on said distal end portions adjacent said hook fastener portion means providing, after the diaper has been soiled and removed from the individual, means for securing the soiled diaper in a rolled or folded condition surrounding the soiled portion of the diaper to facilitate its disposal by engagement of the layer of pressure sensitive adhesive with said laminate.
Claim 2
Dependent Claim
186 words
A disposable garment or diaper including a laminate having first and second opposite ends, and hook and loop fastener means for fastening together portions of said laminate to secure said diaper to an individual, said fastener means including loop fastener portion means adjacent the first end of said laminate comprising a multiplicity of loops, a pair of flexible elongate polymeric tab assemblies having first end portions attached at opposite sides to said laminate adjacent the second end of said laminate and having distal end portions unattached to said laminate, and hook fastener portion means at the distal end portions of said tab assemblies comprising a plurality of projecting hook members adapted to make releasable engagement with said loops, said tab assemblies including a layer of pressure sensitive adhesive on said distal end portions adjacent said hook fastener portion means providing, after the diaper has been soiled and removed from the individual, means for securing the soiled diaper in a rolled or folded condition surrounding the soiled portion of the diaper to facilitate its disposal by engagement of the layer of pressure sensitive adhesive with said laminate.
Claim 3
Dependent Claim
110 words
A disposable garment or diaper according to claim 1, wherein said tab assemblies each comprise an elongate polymeric strip having one end portion attached to said laminate, said strip provides said distal end portion unattached to said laminate, said layer of pressure sensitive adhesive extends entirely along said distal end portion, and said hook fastener portion means for each of said tab assemblies comprises a base having upper and lower major surfaces with said plurality of hook members projecting from the upper surface of said base, said lower major surface of the base being attached to said strip along said distal end portion by said layer of pressure sensitive adhesive.
Claim 4
Dependent Claim
38 words
A disposable garment or diaper according to claim 1, wherein each of said tab assemblies include a release liner releasably adhered over the layer of pressure-sensitive adhesive on said distal end portion adjacent said hook fastener portion means.
Claim 5
Dependent Claim
56 words
A disposable garment or diaper according to claim 3, wherein for each of said tab assemblies said release liner is attached to said laminate, and said distal end portion is folded over to releasably adhere said release liner over the layer of pressure sensitive adhesive on said distal end portion adjacent said hook fastener portion means.
Claim 6
Dependent Claim
69 words
A disposable garment or diaper according to claim 1, wherein said tab assemblies each comprise an elongate polymeric strip attached at one end of said strip to said laminate, said strip provides said distal end portion unattached to said laminate and supports said layer of pressure sensitive adhesive on said distal end portion adjacent said hook fastener portion means, and said hook members are integrally formed with said strip.
Claim 7
Dependent Claim
170 words
A disposable garment or diaper according to claim 1 wherein said tab assemblies each comprise an elongate polymeric strip attached at one end of said strip to said laminate, said strip providing said distal end portion unattached to said laminate with said layer of pressure sensitive adhesive being adhered to said strip adjacent said hook fastener portion means, and an end part of the portion of said polymeric strip defining said distal end portion and carrying said hook fastener portion means for each of said tab assemblies is folded over and releasably engaged with said layer of pressure sensitive adhesive, said hook fastener portion means being engageable with said loop fastener portion means with said end part folded over, and said end part being separable from said layer of pressure sensitive adhesive to afford securing the diaper, when soiled and removed, in a rolled or folded condition surrounding the soiled portion of the diaper to facilitate its disposal by engagement of the layer of pressure sensitive adhesive with said laminate.
