ABSTRACT:
A disposable absorbent article such as an incontinence 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. The absorbent article has a pair of end regions, and a central region disposed between the end regions. The central region includes a pair of spaced apart longitudinal side portions and a central portion disposed between the longitudinal side portions. The absorbent article includes a liquid pervious topsheet, a liquid impervious backsheet joined to the topsheet, an absorbent core positioned between the topsheet and backsheet, and an acquisition component positioned between the topsheet and the absorbent core. The acquisition component has a total void volume. The portion of the acquisition component with the central region provides at least about 50% of the total void volume of the absorbent article. A portion of the absorbent core is folded upon the acquisition component along a first pair of generally parallel longitudinally extending fold lines to form a pair of resilient absorbent members which encapsulate the acquisition component within the longitudinal side portions. The resilient absorbent members are arranged in a longitudinally spaced relation to each other between the acquisition component and the topsheet. The absorbent article has a total absorptive capacity. The central region provides at least about 50% of the total absorptive capacity and the longitudinal side portions provide at least about 70% of the central regions absorptive capacity.
