Disposable diaper with longitudinal anti-leakage means

A disposable diaper, comprising:

• a fluid-impermeable backing layer having opposed inner and outer surfaces, a pair of opposite enlarged ends, and an intermediate narrowed portion integrally formed between the ends;
• an absorbent core having a size smaller than the size of said backing layer, and having a shape conforming with the shape of said backing layer, said absorbent core having opposed sides, one side being disposed on the inner surface of said backing layer;
• adhesive means disposed on the outer surface of said backing layer;
• a fluid-permeable facing layer positioned on the other side of said absorbent core and encompassing said absorbent core, said facing layer being provided with a pair of longitudinal hollow members extending along an entire length of the disposable diaper, and said facing layer being bonded to said backing layer at portions surrounding said absorbent core;
• a plurality of elastic elements received within and secured to a middle portion of each of said hollow members, whereby said hollow members stand upright due to a longitudinal gathering force created by said elastic elements to serve as liquid barriers, so as to provide an enhanced anti-leakage effect;
• and
• a positioning member disposed over said facing layer between said hollow members, wherein the sex organ of a male user is inserted between said facing layer and said positioning member to engage and position the male sex organ and keep the organ dry.
