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 body liquids rapidly without leakage, especially a subsequent gush of liquid. Such an absorbent article comprises a liquid pervious topsheet, a liquid impervious backsheet, a layered expandable absorbent core positioned between the topsheet and the backsheet, at least two resilient shaping members, an acquisition channel, a liquid acquisition zone and at least two liquid impervious shelves. The present invention also relates to an absorbent article provided with an expandable overwrap having an expansion means for allowing the overwrap to expand when the absorbent core swells when wetted. The overwrap of the absorbent article is provided with an expansion means for permitting the overwrap to expand as the absorbent core swells when it is wetted. The expansion means is a releasable tack or other means that releases the overwrap when a slight shearing or peeling force or action is applied to the expansion means. Thus the swelling of the absorbent core is less likely to deform the shape of the pad or cause a loss of the absorptive capacity of the article, especially for subsequent gushes of liquids.
