Patent ID: 7763004

Claim:
A disposable diaper comprising: an absorbent assembly comprising an absorbent core; a chassis having a longitudinal axis, a lateral axis, a front waist region having a front waist edge, a back waist region having a back waist edge, a crotch region between the waist regions, laterally opposing side edges extending between the front waist edge and the back waist edge, and an interior surface, the chassis forming a waist opening and two laterally opposing leg openings when the front waist region and the back waist region are attached together, the chassis comprising a water-impermeable backsheet and laterally opposing layered containment pockets including on each side of the longitudinal axis a lowermost containment pocket and at least one overlying containment pocket layered interiorly of the lowermost containment pocket, each containment pocket having a closed apex formed by folding a portion of the chassis laterally inward, laterally inwardly facing open side having an upper edge disposed proximally relative to the apex, an upper wall connecting the apex and the upper edge, a lower wall, and a depth defined by the upper edge and the apex; a portion of the chassis folded laterally outward to form laterally outwardly extending side flaps disposed interiorly of the layered containment pockets; wherein the absorbent assembly is disposed at least partially laterally between the lowermost containment pockets; wherein a distal edge of each of the side flaps extends laterally distally beyond the apices of the respective layered containment pockets and thereby forms a respective one of the side edges of the chassis; and wherein the depth of the at least one overlying containment pocket is different from the depth of the at least one lowermost containment pocket.
