Abstract
Abstract The pad of the invention is composed of impervious backing sheet and a pervious body-side liner with an absorbent material there between. The pad is elasticized along its edges from points at substantially one end extending along the longer edges of the rectangular pad for at least two-thirds of the length of the pad. In a preferred form of the invention the pad has as its absorbent material a coform structure of air-formed meltblown polymers combined with air-formed cellulose fibers that have been formed onto a pervious spunbonded material that serves as the pervious body-side liner. In the preferred form the backing sheet is formed of an extrusion-coated spunbonded material that has the spunbonded material on the outer surface with the backing sheet folded over to overlap on the body side of the garment with the fabric toward the body. The folded portion forms the pad's baffles. Further, the preferred pad has length of between about 8 and 14 inches, and the width is preferably about 30 percent of the length.

Claims Analysis
Total Claims: 19
Claim 1
Independent Claim
45 words
A bowed, trough-like generally rectangular pad comprising a fluid-impermeable outer cover, a fluid-pervious body-side cover, and an absorbent layer positioned there between, wherein elastic extends along substantially the entire length of the longer edges of said pad and forms said pad into a bowed trough.
Claim 2
Dependent Claim
45 words
A bowed, trough-like generally rectangular pad comprising a fluid-impermeable outer cover, a fluid-pervious body-side cover, and an absorbent layer positioned there between, wherein elastic extends along substantially the entire length of the longer edges of said pad and forms said pad into a bowed trough.
Claim 3
Dependent Claim
39 words
The pad of Claim 1 wherein its length when pressed flat is between about 80 and 90 percent of about 8 and about 14 inches, and the width is about 30 percent of about 8 to about 14 inches.
Claim 4
Dependent Claim
17 words
The pad of Claim 1 wherein said fluid pervious body-side cover is adhered to said absorbent layer.
Claim 5
Dependent Claim
13 words
The pad of Claim 1 wherein the trough is about 1 inch deep.
Claim 6
Dependent Claim
13 words
The pad of Claim 1 wherein said cover comprises a fabric-covered polymer film.
Claim 7
Dependent Claim
21 words
The pad of Claim 1 wherein the length of said pad when flattened is between about 6.4 and about 12.6 inches.

Claim 10
Dependent Claim
21 words
The pad of Claim 1 wherein said absorbent has the capacity to retain up to about 60 cc of aqueous fluid.
Claim 11
Dependent Claim
74 words
An elongated generally rectangular absorbent pad comprising a fluid-impermeable outer cover, a fluid-pervious body-side cover, and an absorbent layer positioned there between, wherein the long edges of said absorbent pad are elasticized in each long edge area extending from at least one end of said pad to a point at least about two-thirds of the distance to the other end thereby forming a trough-like shape in the at least elasticized portion of said pad.
Claim 12
Dependent Claim
74 words
An elongated generally rectangular absorbent pad comprising a fluid-impermeable outer cover, a fluid-pervious body-side cover, and an absorbent layer positioned there between, wherein the long edges of said absorbent pad are elasticized in each long edge area extending from at least one end of said pad to a point at least about two-thirds of the distance to the other end thereby forming a trough-like shape in the at least elasticized portion of said pad.
Claim 13
Dependent Claim
