Abstract
Abstract A diaper including a part for blocking movement of fecal material rearwardly out of the gluteal groove. The diaper comprises a core of absorbent material covered by top and back sheets, and a back area covering the gluteal groove. The diaper further comprises a blocking part in the back area, the blocking part being operable to create pressure in the gluteal groove to prevent the flow of fecal material rearwardly through the groove. The blocking part conforms to the shape of the groove, and it has compression and recovery ratios which enhance the conformity.
