ABSTRACT:
An infant diaper has a coherent absorbent pad with a pair of exterior longitudinal pad margins oppositely disposed to each other. The absorbent pad area has a central pad area in combination with an opposed pair of absorbent border pad areas, each one of the opposed border pad areas has one longitudinal boundary margin adjacently coextensive with one longitudinal boundary margin of the central pad area. A central optimum pad area can have a discrete weight greater than each one of the border pad areas. A pair of parallel, narrow width pleats are disposed the full longitudinal pad axis length. Each one of the pair of pleats can be formed of the central pad area and are disposed on the same first face of the central pad area adjacent to the longitudinal boundary margin of the central pad area. Each one of the pleats can have a pleat apex disposed nearer or further from the central longitudinal pad axis than the corresponding companion pleat base fold. A thin, flexible, fluid impermeable membrane is contiguously disposed coextensive with the second face of the absorbent pad area opposite the first pad face, specifically excluding the side width values of the pair of narrow width pleat sides. The membrane also forms each one of a pair of opposed longitudinal border seals.
