Abstract

A disposable absorbent product such as a sanitary napkin or an urinary pad including a liquid-permeable cover layer, and absorbent core and a liquid-impervious layer for preventing body exudate entrapped in the absorbent core from contacting the wearer's undergarment or skin. A secondary liquid containment structure for intercepting body exudate leaking past the side edges of the absorbent product is mounted underneath the liquid-impervious layer. The containment structure includes a transversely extending strip of absorbent material such as non-woven fabric, having longitudinal end portions forming liquid-acquisition zones. The central portion of the absorbent strip constitutes a reservoir layer for collecting the body exudate discharged on the liquid-acquisition zones. In a preferred embodiment, the longitudinal end portions of the strip are sufficiently long to form tabs capable of being folded about the edges of the undergarment for stabilizing the absorbent product against the perineal region of the wearer. In a variant, the positioning tabs incorporate the secondary liquid-containment structure.
Each positioning tab includes a layer of porous material enclosed on all sides by a liquid-impermeable layer except at a side edge portion that is adjacent to the side edge of the disposable absorbent product. The side edge portion of the positioning tab constitutes a liquid-acquisition zone capable of intercepting body exudate leaking past the edge of the disposable absorbent product.
