1. In a disposable diaper of incontinent brief having an essentially coextensive thin moisture impervious thermoplastic backsheet, a moisture absorbent cellulose pad, and a moisture previous skin contacting nonwoven topsheet, the diaper being of generally rectangular configuration having longitudinal side portions and transverse front and back end portions, the improvement which comprises:

  • a. front and rear flap means formed by extensions of the backsheet and topsheet beyond the absorbent pad, the front flap being longer than the rear flap and the combined lengths of the flaps being from 15-25% of the total length of the diaper;

    b. two attachment straps means permanently bonded at their proximal ends to each rear flap means, each strap having an adhesive distal end for securing the diaper to a wearer and an adhesive free zone between the proximal and distal ends;

    c. elastic means located adjacent to and parallel to each longitudinal edge, each elastic means running essentially the full length of the diaper and serving to hold the edges of the brief in close leak-resisting contact with the body of the wearer;

    d. the moisture absorbent pad having a crotch area cutout portion along each longitudinal side to give it a generally hourglass-shaped configuration, the longitudinal centers of the cutout portions being located forward of the front-to-back transverse centerline of the pad so that when in use by a wearer the back edge of the diaper is located near the waistline and is higher on the body than the front edge, the crotch area cutout being formed so that the acute angle between a chord drawn from the front of the cutout to the deepest portion and a projection of the side of the diaper is smaller than the acute angle between the chord drawn from the rear of the cutout to the deepest portion and the side projection.
