Abstract
Abstract The invention is generally accomplished by providing an elongated, curved, better-fitting absorbent pad for absorption of bodily excretions comprising a liquid-impermeable backing member, an absorbent inner member and a liquid-permeable body-side member. The absorbent member is shaped generally in a manner that provides a narrower middle portion of absorbent material. The middle portion also in the preferred embodiment is somewhat thicker than the absorbent portions at the ends of the pad. The pad is provided with upstanding side portions in the middle of each long edge in the area where the absorbent is narrower. The pad further is curved so as to generally conform to the pudendum.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
168 words
An elongated catamenial or mold incontinence pad curved to the body shape having relatively long sides and narrowed ends for absorption of bodily excretions comprising a liquid-impermeable backing member having generally parallel longitudinal sides, an hour glass shape absorbent inner member and a liquid-permeable body-side member, wherein said absorbent generally has a narrow center portion shape, said backing member extends beyond said absorbent and has side edges forming flaps in the areas where the narrower portion of the absorbent does not overlay said backing, said flaps being gathered thereby raising said flap to form a wall on each side of the narrower portion of said absorbent wherein the distance between said walls is about the width of the widest part of said absorbent, wherein said absorbent is 1.75-3 times thicker in the middle of said pad than at the ends, wherein elastic is coextensive with the flap and wherein said flaps extend upward from about the middle of the vertical height of the thickest portion of said absorbent.
