ABSTRACT:
A disposable diaper includes a fluid-impermeable backing layer having a pair of opposite enlarged ends and an intermediate narrowed portion integrally formed therebetween. An absorbent core has a size that is smaller than and in conformity with the size of the backing layer. The absorbent core is disposed at one side on an inner surface of the backing layer. An adhesive unit is disposed at an outer surface of the backing layer. A fluid-permeable facing layer is positioned on the other side of the absorbent core and encompasses the absorbent core. The facing layer is provided with a pair of longitudinal hollow members which extend along the length of the disposable diaper. The facing layer is attached at an edge other than the edge portion forming the hollow members to a corresponding edge of the backing layer. A plurality of elastic elements are received within and are secured to a middle portion of each of the hollow members. The hollow members stand upright due to the longitudinal gathering force that is created by the elastic elements to serve as liquid barriers so as to provide an enhanced anti-leakage effect.
