ABSTRACT:
A disposable absorbent product such as a sanitary napkin, a diaper, an adult disposable brief or an urinary pad, among others, 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.
