Abstract
Abstract A fundamentally conventional diaper having an absorbent pad between an impervious backing material and a pervious facing has its margins folded toward each other with the backing material outermost. Each margin is provided with an adhesively coated tab for use in applying the diaper, a portion of the length of each tab being adherent to the exposed plastic backing of the diaper and another portion being folded back on itself with the coating exposed. At least one such folded back portion is held in position by a spot of hot melt adhesive which connects it to the underlying part of the tab. A strip of polyethylene releasably engages the exposed adhesive surfaces of respective tabs and preferably spans the gap between them whereby a single release facing strip of approximately half the length normally used not only protects the adhesive surfaces of both tabs but also connects two margins of the folded diaper.

The combination with a diaper folded to provide proximate margins and having an impervious backing ply, of a diaper mounting tab having an adhesive coating and attached thereby for a portion of the length of the tab to the backing ply approximately at right angles to one of said margins and having an end portion onto which said coating extends and which is folded back away from said last margin and over the portion which is adhesively attached to the backing ply, and has its adhesive coating outermost, and a release facing strip detachably covering the coating on said end portion, the length of the facing strip being at least approximately as great as the length of the backfolded end portion of said tab.
Claim 2
Dependent Claim
124 words
The combination with a diaper folded to provide proximate margins and having an impervious backing ply, of a diaper mounting tab having an adhesive coating and attached thereby for a portion of the length of the tab to the backing ply approximately at right angles to one of said margins and having an end portion onto which said coating extends and which is folded back away from said last margin and over the portion which is adhesively attached to the backing ply, and has its adhesive coating outermost, and a release facing strip detachably covering the coating on said end portion, the length of the facing strip being at least approximately as great as the length of the backfolded end portion of said tab.
Claim 3
Dependent Claim
44 words
A combination according to claim 1 in which a release facing strip detachably covers the adhesive coating on the back-folded end portion of said tab, said strip having an exposed end projecting from the diaper to facilitate removal of the strip from the tab.
Claim 4
Dependent Claim
73 words
A combination according to claim 1 in which each of said margins bears exposed surfaces of said backing ply, both of said margins having mounting tabs with an adhesive coating, adhesively attaching a portion of at least one of said tabs to exposed surfaces of the backing ply, a single facing strip spanning the said margins of the diaper and being releasably engaged with the back-folded end portions of both of said tabs.
Claim 5
Dependent Claim
37 words
A combination according to claim 3 in which the back-folded end portions of both of said tabs have spot adhesive connection to the underlying portions of the respective tabs which are adhesively attached to the backing ply.
Claim 6
Dependent Claim
152 words
The combination with a diaper folded to provide proximate margins and having an impervious backing ply, of a diaper mounting tab having an adhesive coating and attached thereby for a portion of the length of the tab to the backing ply approximately at right angles to one of said margins and having an end portion onto which said coating extends and which is folded back away from said last margin and over the portion which is adhesively attached to the backing ply, and has its adhesive coating outermost, and a release facing strip detachably covering the coating on said end portion, the length of the facing strip being at least approximately as great As the length of the back-folded end portion of said tab and a releasable adhesive spot connecting the back-folded end portion of the tab to the tab portion which is adhesively attached to the backing ply of the diaper.
Claim 7
Dependent Claim
152 words
The combination with a diaper folded to provide proximate margins and having an impervious backing ply, of a diaper mounting tab having an adhesive coating and attached thereby for a portion of the length of the tab to the backing ply approximately at right angles to one of said margins and having an end portion onto which said coating extends and which is folded back away from said last margin and over the portion which is adhesively attached to the backing ply, and has its adhesive coating outermost, and a release facing strip detachably covering the coating on said end portion, the length of the facing strip being at least approximately as great As the length of the back-folded end portion of said tab and a releasable adhesive spot connecting the back-folded end portion of the tab to the tab portion which is adhesively attached to the backing ply of the diaper.
Claim 8
Dependent Claim
46 words
A combination according to claim 5 in which the release facing strip is longer than said back-folded end portion of said tab, and has a length of said strip exposed to be grasped for pulling the strip from the adhesive coating on the back-folded end portion.
Claim 9
Dependent Claim
116 words
The combination with a diaper having an impervious backing ply, a pad, and a pervious facing ply, said diaper being longitudinally folded and having side marginal portions of said backing ply disposed in proximity over said pad and facing ply, separate mounting tabs having adhesive coatings and each having an adhesively coated first end portion adherent to the diaper backing ply adjacent one of the diaper margins, each such tab being transversely folded back upon itself to expose an adhesively coated second end portion over its first-mentioned end portion, and a single facing ply detachably adherent to the adhesive coatings on the respective second end portions of said tabs and spanning the space between said tabs.
Claim 10
Dependent Claim
116 words
The combination with a diaper having an impervious backing ply, a pad, and a pervious facing ply, said diaper being longitudinally folded and having side marginal portions of said backing ply disposed in proximity over said pad and facing ply, separate mounting tabs having adhesive coatings and each having an adhesively coated first end portion adherent to the diaper backing ply adjacent one of the diaper margins, each such tab being transversely folded back upon itself to expose an adhesively coated second end portion over its first-mentioned end portion, and a single facing ply detachably adherent to the adhesive coatings on the respective second end portions of said tabs and spanning the space between said tabs.
Claim 11
Dependent Claim

A combination according to claim 7 in which at least one of said tabs has a spot adhesive connection between its respective end portions.
Claim 12
Dependent Claim
104 words
The combination with a diaper having an impervious backing ply, a pervious facing ply, and an absorbent pad, of a diaper mounting tab having an adhesive coating attached for a portion of the length of the tab to the backing ply adjacent a diaper side margin and being transversely folded back upon itself to provide an end portion projecting away from said last-mentioned margin of the diaper and upon which said coating extends, and a release facing strip covering the adhesive coating extending to said last end portion of the mounting tab, said strip projecting beyond the mounting tab across the said diaper margin.
Claim 13
Dependent Claim
