Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
111 words
A multi-layer diaper comprising: a rectangular waterimpervious backing sheet; an absorbent batt in juxtaposition with said backing sheet, said batt being smaller than said backing sheet and centrally disposed with respect thereto, said batt comprising a unitary, highly porous, loosely compacted, cellulosic fibrous layer continuous throughout its thickness and having a smaller quantity of fibers in at least two opposite marginal portions of its area than in a central portion therebetween, said batt having a smooth and gradual thickness contour between said marginal portions and said central portion; and a rectangular porous facing layer disposed over said batt, said loosely compacted batt having greater wettability to water than said facing layer.
Claim 2
Dependent Claim
111 words
A multi-layer diaper comprising: a rectangular waterimpervious backing sheet; an absorbent batt in juxtaposition with said backing sheet, said batt being smaller than said backing sheet and centrally disposed with respect thereto, said batt comprising a unitary, highly porous, loosely compacted, cellulosic fibrous layer continuous throughout its thickness and having a smaller quantity of fibers in at least two opposite marginal portions of its area than in a central portion therebetween, said batt having a smooth and gradual thickness contour between said marginal portions and said central portion; and a rectangular porous facing layer disposed over said batt, said loosely compacted batt having greater wettability to water than said facing layer.
Claim 3
Dependent Claim
15 words
The diaper of claim 1 wherein said marginal portions are side portions of said batt.
Claim 4
Dependent Claim
36 words
The diaper of claim 1 wherein said batt is contoured convexly about the transverse and longitudinal medians thereof and the ratio of contour apex thickness to corner thickness is in the range of 1.5 to 4.
Claim 5
Dependent Claim
178 words
A multi-layer diaper comprising: a rectangular water-impervious backing sheet; a rectangular absorbent batt in juxtaposition with said backing sheet, said batt being smaller than said backing sheet and centrally disposed with respect thereto, said batt comprising a unitary, highly porous, loosely compacted cellulosic fibrous layer having a paper-like, densified, compacted cellulosic fibrous layer of relatively high wettability and relatively high fluid retentivity formed integrally therewith, said densified layer being positioned in face-to-face engagement with said backing sheet, the quantity of fibers in said batt increasing gradually from both side edge portions and both end edge portions to the central portion of said batt thereby to produce a smooth convex thickness contour in the surface of the batt opposite said densified layer about the transverse and longitudinal medians of the batt in which the ratio of apex thickness to corner thickness in said batt is in the range of 1.5 to 4; and a rectangular porous facing layer disposed over the contoured portion of said batt, said loosely compacted batt having greater wettability to water than said facing layer.
Claim 6
Dependent Claim
178 words
A multi-layer diaper comprising: a rectangular water-impervious backing sheet; a rectangular absorbent batt in juxtaposition with said backing sheet, said batt being smaller than said backing sheet and centrally disposed with respect thereto, said batt comprising a unitary, highly porous, loosely compacted cellulosic fibrous layer having a paper-like, densified, compacted cellulosic fibrous layer of relatively high wettability and relatively high fluid retentivity formed integrally therewith, said densified layer being positioned in face-to-face engagement with said backing sheet, the quantity of fibers in said batt increasing gradually from both side edge portions and both end edge portions to the central portion of said batt thereby to produce a smooth convex thickness contour in the surface of the batt opposite said densified layer about the transverse and longitudinal medians of the batt in which the ratio of apex thickness to corner thickness in said batt is in the range of 1.5 to 4; and a rectangular porous facing layer disposed over the contoured portion of said batt, said loosely compacted batt having greater wettability to water than said facing layer.
