Abstract
Abstract A single use, rectangular area, disposable diaper pad has an optimum profile absorbent diaper pad formed of multiple ply of absorbent tissue paper sheets disposed coplanarly adjacent. A first plurality of equal width, fluid absorbent tissue paper ply are coplanarly adjacently disposed along a first absorbent pad longitudinal diaper pad margin forming a first absorbent pad subgroup. A second plurality of equal width, fluid absorbent tissue paper sheet ply are coadjacently disposed along an opposed second longitudinal diaper pad margin forming a second absorbent padsub-group. The first sub-group, and the second sub-group, have cooperative sub-group widths adapting the second sub-group to partially overlay a substantial portion of the first sub-group width. The succeeding third sub-group, fourth sub-group and the consecutive like, alternatively partially overlay the sub-group below to form an absorbent pad having a thicker fluid absorptive structure central pad disposed the length of a diaper pad. The optimum absorbent pad profile is centrally disposed in the diaper to absorb the waste products from an infant conventionally secured in the disposable diaper, with the longitudinal pad margins parallel to the infant''s legs.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
175 words
In an infant diaper having a rectangular, multiple ply, coplanar marginally aligned fluid absorbent tissue paper sheet pad area, said pad area having a pair of longitudinal diaper pad margins oppositely disposed to each other, a central longitudinal diaper pad axis and a diaper total pad width axis normal to said longitudinal diaper pad axis, the optimum profile fluid absorbent diaper comprising: at least two sub-groups of marginally aligned, plural, fluid absorbent tissue paper sheet pad areas, each consecutive one of said sub-group pad areas having one longitudinal margin serially coincident with one alternative longitudinal diaper pad margin, each one of said serial sub-group pad areas providing a substantial overlap width of the serially subsequent sub-group, providing a central optimum pad area having the required multiplicity of fluid absorbent tissue paper sheets; and, a thin, fluid impermeable membrane adjacently coextensive with one face of said rectangular pad area, having each one of a pair of opposed longitudinal border seals disposed on said pair of longitudinal diaper pad margins, said seals securing said diaper pad margins.
Claim 2
Dependent Claim
