Abstract

In an infant disposable diaper the absorbent diaper pad for body excreta has a pair of narrow width pleats disposed in the absorbent pad. Each one of the pleats being oppositely disposed parallel along the full longitudinal length of the diaper pad, the pair of pleats being separated by a suitable width of absorbent pad, providing a central pad channel width as a urine and feces trap and an excreta channel pad area suitable for containment of excreta between the pleat pair. Each one of the pad pleats can be formed of the central optimum pad area and each pleat is disposed on the exterior first face of the diaper pad. Each pleat is disposed adjacent to the longitudinal exterior margin of the central pad area. A thin, flexible, fluid impermeable membrane is contiguously disposed coextensive with the second face of the diaper pad area. The impermeable membrane is specifically excluded from contact with the side width values of the pair of narrow width pleat sides. The membrane is fixed in position and secured to the pad by at least a pair of opposed longitudinal border seals.
