Abstract

A disposable absorbent article such as a diaper with a liquid pervious topsheet, a liquid impervious backsheet, an absorbent core disposed between the topsheet and the backsheet, flexible side flaps extending outwardly from and along each side edge of the absorbent core in at least the crotch region of the diaper, elastic members secured to the side flaps, and a reservoir. The reservoir collects and holds body exudates, especially loose fecal material, until the diaper is removed. Leakage prevention is enhanced because body exudates would have to flow not only above and over the reservoir but also beyond the elasticized side flaps; leakage being additionally prevented by the elasticized side flaps because they form an additional liquid impervious barrier about the body of the wearer.
