Abstract
A disposable absorbent article having a topsheet, a backsheet, an absorbent core, first flaps and second flaps. Each of second flaps is connected to the first flap and has a section branching upward and a section extending outward. The branching section is partially elastic. The extending section is so constructed as to be liquid-absorbent on its top surface.

A disposable liquid absorbing article comprising
- (A) liquid-permeable topsheet (2),
- (B) a liquid-impermeable backsheet (3),
- (C) an absorbent core (4) sandwiched between said top- and backsheets,
- (D) a first set of flaps (5) formed from said topsheet (2) and said backsheet (3) extending laterally outwardly from opposite side edges of the absorbent core (4), and
- (E) a second set of flaps (7) which is formed from material separate from the materials forming said topsheet (2) and said backsheet (3), each of said second flaps (7) being connected to one of each of said first flaps (5), each of said second flaps (7) comprising
- (a) a first section (11) which is formed from material separate from the material forming said topsheet (2) and which extends upwardly from the surface of each first flap (5) and being partially elastic so as to serve as a moisture-permeable liquid barrier, and
- (b) a second section (13) which is also formed from material separate from the material forming said topsheet (2) extending laterally outward from the lower portion of each said first section (11), each second section (13) comprising
- (i) a lower sheet-like layer (10) made of liquid-impermeable and moisture-permeable material, and
