Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
143 words
A disposable nursing or incontinent pad or the like adapted to absorb body fluids, comprising in layered relation: a rectilinear absorbent matrix having a facing side and a backing side, a facing sheet, and a water-impervious backing sheet, the matrix being sealingly enveloped within the facing and backing sheets and having its lateral edges infolded onto the facing side in a C-fold configuration to provide two spaced apart infolded flaps and a middle portion between the fold lines, the facing sheet being wider than the matrix and extending over the facing side of the middle portion and the outer and inner faces of each of the infolded flaps, the backing sheet being narrower than the matrix and overlapping the facing sheet on said outer face such that the pad in fluid absorbing relation with the body is resistant to lateral run-off of fluid.
Claim 2
Dependent Claim
143 words
A disposable nursing or incontinent pad or the like adapted to absorb body fluids, comprising in layered relation: a rectilinear absorbent matrix having a facing side and a backing side, a facing sheet, and a water-impervious backing sheet, the matrix being sealingly enveloped within the facing and backing sheets and having its lateral edges infolded onto the facing side in a C-fold configuration to provide two spaced apart infolded flaps and a middle portion between the fold lines, the facing sheet being wider than the matrix and extending over the facing side of the middle portion and the outer and inner faces of each of the infolded flaps, the backing sheet being narrower than the matrix and overlapping the facing sheet on said outer face such that the pad in fluid absorbing relation with the body is resistant to lateral run-off of fluid.
