Abstract
The present invention provides a disposable absorbent article such as an incontinent pad that is both comfortable and suitable for absorbing and containing large volumes of bodily liquids without leakage. Such an absorbent article includes a liquid pervious topsheet, a liquid impervious backsheet joined to the topsheet, and an absorbent core positioned between the topsheet and the backsheet. The absorbent core includes a material which expands when wetted. The backsheet includes at least one pleat which is tacked with a liquid soluble adhesive such that when the liquid soluble adhesive is wetted the adhesive dissolves allowing the pleat to expand as the absorbent core expands. The pleats may extend in any direction, but preferably extend either substantially parallel to the longitudinal axis of the article or substantially parallel to the transverse axis of the absorbent article.
