Abstract
Abstract An adhesive tape tab for use on disposable diapers which may be peeled and re-used for subsequent fastenings of the diaper without tearing the outside plastic film of the diaper or the tape tab itself. The tape tab has a tape which is fastened on one portion to the diaper. A second, extendable portion of the tape has adhesive material thereon, however, the adhesive material is interrupted and divided into segments by nonadhesive areas formed by a nonadhesive open-mesh sheet material. Each of these adhesive segments has an area so that when the second portion of tape is attached to the outside film the peel strength between tape and film over the segmented area is less than the tearing strength of the film over the same segmented area.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
185 words
In a disposable diaper of the type having an inside surface and an absorbent layer between said surfaces, and an adhesive tape tab for repositionable and reapplicable use on said diaper, said adhesive tape tab having a first portion attached to one part of the diaper and having a second extendable portion for attachment to said outside film on another part of the diaper; adhesive material on one surface of the second portion of said adhesive tape tab, said adhesive material being interrupted and divided into segments by filaments and intersections of a nonadhesive, open-mesh sheet material on said surface of the second portion of the adhesive tape tab, said openings of said sheet material defining the adhesive segments, each of said adhesive segments having an area so that the peel strength between said section portion of adhesive tape tab and said film over said segmented area is less than the tearing strength of said film over the same segmented area, but providing, on a combined basis with a plurality of similar adhesive segments, adequate holding strength of the adhesive tape tab to the diaper.
Claim 2
Dependent Claim
185 words
In a disposable diaper of the type having an inside surface and an absorbent layer between said surfaces, and an adhesive tape tab for repositionable and reapplicable use on said diaper, said adhesive tape tab having a first portion attached to one part of the diaper and having a second extendable portion for attachment to said outside film on another part of the diaper; adhesive material on one surface of the second portion of said adhesive tape tab, said adhesive material being interrupted and divided into segments by filaments and intersections of a nonadhesive, open-mesh sheet material on said surface of the second portion of the adhesive tape tab, said openings of said sheet material defining the adhesive segments, each of said adhesive segments having an area so that the peel strength between said section portion of adhesive tape tab and said film over said segmented area is less than the tearing strength of said film over the same segmented area, but providing, on a combined basis with a plurality of similar adhesive segments, adequate holding strength of the adhesive tape tab to the diaper.
Claim 3
Dependent Claim
16 words
An adhesive tape tab as defined in claim 1 wherein the open-mesh sheet material is plastic.
Claim 4
Dependent Claim
32 words
An adhesive tape tab as defined in claim 2 wherein the plastic material is flat and sheet-like with a multiplicity of openings formed by filaments which are integrally joined at the intersections.
Claim 5
Dependent Claim
32 words
An adhesive tape tab as defined in claim 3 wherein the openings have an area less than 0.250 square inches, and wherein said filaments have a thickness between 0.002 and 0.012 inches.
Claim 6
Dependent Claim
52 words
An adhesive tape tab as defined in claim 1 wherein a segment at the furthest edge of the extendable second portion of tape has nonadhesive surfaces to act as a pull-tab to facilitate peeling after the second portion of the adhesive tape tab has been fastened to the outside film during use.
Claim 7
Dependent Claim
38 words
An adhesive tape tab as defined in claim 1 wherein a segment of nonadhesive, open-mesh sheet material extends beyond the furthest edge of the second portion of said adhesive tape tab to provide a pull-tab for peeling purposes.
Claim 8
Dependent Claim
63 words
An adhesive tape tab as defined in claim 1 wherein a segment of the second portion of said adhesive tape tab extends beyond the distal edge of the open sheet material and is folded back upon itself with the end portion of the open sheet material being interposed therebetween, the outside surfaces of said folded segment being nonadhesive whereby a pull-tab is formed.
