Abstract
Abstract A substantially flat menstrual or incontinent pad embodying a longitudinal centrally located narrow rib or ridge on its top surface adapted to enter into the vaginal cleft to increase its fluid absorptive capacity and wherein the flat top surface of the pad on each side of the central ridge, and on the ridge itself, are provided with a multitude of relatively deep spaced apart channels and/or deep spot-depressions which increase the lateral compressibility of the flat marginal surfaces and/or the ridge without the usual down-folding of said flat surfaces when subjected to lateral compression when arranged between the thighs of a wearer.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
83 words
A sanitary absorbent pad comprising an elongated body of fluid absorbent material, said body being substantially flat and having top and bottom surfaces, a longitudinal ridge on the top surface of the body midway between the longitudinal edges of said body, said ridge dividing the top area of the pad into two flat lateral areas, and a multltude of relatively deep depressions in said ridge and in each of said flat lateral areas, said depressions reducing resistance to lateral compression of said pad.
Claim 2
Dependent Claim
83 words
A sanitary absorbent pad comprising an elongated body of fluid absorbent material, said body being substantially flat and having top and bottom surfaces, a longitudinal ridge on the top surface of the body midway between the longitudinal edges of said body, said ridge dividing the top area of the pad into two flat lateral areas, and a multltude of relatively deep depressions in said ridge and in each of said flat lateral areas, said depressions reducing resistance to lateral compression of said pad.
Claim 3
Dependent Claim
16 words
The sanitary pad described in claim 1, wherein said deep depressions comprise spaced apart parallel channels.
Claim 4
Dependent Claim
17 words
The sanitary pad described in claim 2, wherein the channels extend end to end of the pad.
Claim 5
Dependent Claim

The sanitary pad described in claim 1, wherein the depressions comprise a multitude of small longitudinally and laterally spaced apart deep depressions in at least the top surface of each lateral area and in the ridge.
Claim 8
Dependent Claim
96 words
A sanitary absorbent pad comprising an elongated gody of flud absorbent material, said body being sugstantially flat and having top and bottom surfaces, a longitudinal ridge on the top surface of said body midway between the longitudinal edges of said body, a multitude of relatively deep depressions in said ridge and in the top surface of the pad, a series of deep depressions in the bottom surface of the pad, said depressions reducing the resistance to lateral compression of said pad, and said last named depressions being offset laterally from the depressions in the top surface.
Claim 9
Dependent Claim
96 words
A sanitary absorbent pad comprising an elongated gody of flud absorbent material, said body being sugstantially flat and having top and bottom surfaces, a longitudinal ridge on the top surface of said body midway between the longitudinal edges of said body, a multitude of relatively deep depressions in said ridge and in the top surface of the pad, a series of deep depressions in the bottom surface of the pad, said depressions reducing the resistance to lateral compression of said pad, and said last named depressions being offset laterally from the depressions in the top surface.
Claim 10
Dependent Claim
96 words
A sanitary absorbent pad comprising an elongated body of fluid absorbent material, said body being substantially flat and having top and bottom surfaces, a longitudinal ridge on the top surface of the body, said ridge dividing the top area of the pad into two flat lateral areas, a multitude of relatively deep depressions in said ridge and in each of said flat lateral areas, said depressions reducing resistance to lateral compression of said pad, and adhesive means arranged on the bottom surface of the pad to assist retention of the pad in place while in use.
Claim 11
Dependent Claim
96 words
A sanitary absorbent pad comprising an elongated body of fluid absorbent material, said body being substantially flat and having top and bottom surfaces, a longitudinal ridge on the top surface of the body, said ridge dividing the top area of the pad into two flat lateral areas, a multitude of relatively deep depressions in said ridge and in each of said flat lateral areas, said depressions reducing resistance to lateral compression of said pad, and adhesive means arranged on the bottom surface of the pad to assist retention of the pad in place while in use.
