WIPO Patent Application WO/2010/113562

Kind Code:

A1

Abstract:

Provided is an absorbent article that can absorb bodily fluid both from the body side of a liquid-absorbing structure and from the opposite side thereof, even after the liquid-absorbing structure has absorbed bodily fluid, and can make effective use of a liquid-absorbing core material. The crotch piece (40) of the diaper (10) includes a set of skin-contact sheets (50) separated in the horizontal (X) direction, and a back sheet (60); also, an opening (41) is formed by a skin-contact inner edge (53) and front and rear second waist end edges (25, 35). Multiple elastic crotch strips (55) are attached at the skin-contact inner edge (53), and the length in the vertical (Y) direction becomes, in effect, smaller. The skin-contact inner edge (53) is separated from the back sheet (60) in the thickness direction, forming a space (42) between the skin-contact sheet (50) and the back sheet (60). A liquid-absorbing structure (70) is formed inside said space (42). The liquid-absorbing structure (70) includes a folded part (77) folded at a fold line (76). The convex side of the folded part (77) is joined to the skin-contact inner edge (53) of the skin-contact sheet (50).
