Abstract
An absorbent article includes a liquid-permeable upper sheet, a liquid impermeable bottom sheet, and an absorbent body between the bottom sheet and the upper sheet, and at least one longitudinally extending liquid barrier comprising an elongated elastic element and an elongated, essentially liquid-impermeable and inelastic material on each side of a longitudinal center line. A liquid impermeable top sheet with an aperture intended to lie in register with a wearer's anus and urethral orifice may also be included. A prestretched elastic band is attached to either an edge of an inelastic material of the liquid impermeable barrier or to the aperture-defining edge of the liquid permeable top sheet. When the article is donned, the elastic device will lie against a wearer, with a free part facing toward the longitudinal center line and a stretchable, puckered sealing edge facing outward from the longitudinal center line.
