Title:
ABSORBENT ARTICLE
Document Type and Number:
WIPO Patent Application WO/2013/047268
Kind Code:
A1
Abstract:
Provided is an absorbent article which enables the dimension in the thickness direction to be reduced, enables softness to be maintained, does not make a wearer feel uncomfortable, and does not have body fluids remaining on a top surface sheet for a long time. A sanitary napkin (10), which serves as the absorbent article, is provided with: a liquid-permeable surface sheet (11), which has a vertical direction (Y) and a horizontal direction (X) and a thickness direction (Z) that are orthogonal to each other, and is disposed in one of the thickness directions (Z) so as to be positioned on the skin-facing surface side of a wearer; a rear surface sheet (12) which is disposed in the other of the thickness directions (Z) and is positioned on a non-skin-facing surface side of the wearer; and a liquid-absorbing structure (20) that is disposed between the surface sheet (11) and the rear surface sheet (12). The liquid-absorbing structure (20) is provided with: a first liquid-permeable sheet (21) positioned on the skin-facing surface side; a second sheet (22) positioned on the non-skin-facing surface side; and a core (23) that absorbs body fluids, which is disposed between the first sheet (21) and the second sheet (22). Compression recesses (30), which compress toward the skin-facing surface side from the non-skin-facing surface side, are formed on a portion of the liquid-absorbing structure (20). Each compression recess (30) is provided with high-compression recesses (31), the dimensions of which are relatively small in the thickness direction (Z), and a low-compression recess (32), the dimension of which is relatively large in the thickness direction (Z). Multiple high-compression recesses (31) are formed in a dotted form in the vertical direction (Y) and the horizontal direction (X). The low-compression recesses (32) are formed in such a manner as to link a high-compression recess (31) with a high-compression recess (31) in the vertical direction (Y) and the horizontal direction (X).
