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: 22
Claim 1
Independent Claim
87 words
An elongated generally rectangular absorbent mild incontinence or catamenial pad comprising a fluid-impermeable outer cover, a fluid-pervious bodyside cover and an absorbent positioned therebetween, wherein the long edges of said pad are elasticized by stretchable elastic from one end of the pad to a point about two-thirds of the distance to the other end of said pad thereby forming a trough-like shape in the elasticized portion of said pad when said elastic is relaxed and wherein said pad forms a j-shape when the elasticized portion is relaxed.
Claim 2
Dependent Claim
87 words
An elongated generally rectangular absorbent mild incontinence or catamenial pad comprising a fluid-impermeable outer cover, a fluid-pervious bodyside cover and an absorbent positioned therebetween, wherein the long edges of said pad are elasticized by stretchable elastic from one end of the pad to a point about two-thirds of the distance to the other end of said pad thereby forming a trough-like shape in the elasticized portion of said pad when said elastic is relaxed and wherein said pad forms a j-shape when the elasticized portion is relaxed.
