Abstract
Abstract An absorbent article is disclosed which has a cup-shaped configuration which prevents side leakage of body fluid and better conforms to the curve shape of a human torso. The absorbent article includes an absorbent having a first surface which faces the body of a user and a second surface aligned opposite to the first surface. The absorbent has a pair of longitudinally extending arcuate sides which are arranged to be close to each other at a point approximate a central portion of the absorbent. A fluid permeable cover is positioned adjacent to at least the first surface of the absorbent and a fluid-impermeable baffle is positioned adjacent to at least the second surface of the absorbent. The cover and baffle are sealed together to enclose the absorbent. The seal is formed inward of the outer peripheral edge of the article. The article further includes a pair of elastic members affixed between the cover and the baffle, outward of the seal and aligned adjacent to the central portion of the absorbent. The elastic members cause the absorbent article to acquire a cup-shaped configuration which corresponds to the perineal area of a user.
