Abstract

Disclosed is an absorbent article including: a main body portion having longitudinally opposed front and rear edges; and a surface structure having an ability to absorb and retain a liquid. The surface structure extends longitudinally of the main body portion and is fixed on a body surface of the main body portion through a bond. The bond extends longitudinally of the main body portion to have longitudinally opposed front and rear edges. The surface structure is longitudinally sectionalized into a front portion having the bond therein and a rear free portion extending beyond the rear edge of the bond toward the rear edge of the main body portion. A width of the rear free portion is smaller than a width of the main body portion and also smaller than a width of the front portion of the surface structure.

Description

technical field [0001] The present invention relates to an absorbent article used as a sanitary napkin, a urine pad, etc., and more particularly relates to an absorbent article that can make the rear part of the absorbent member follow the movement of the user's body, and can improve close contact with the user's body. of absorbent articles. Background technique [0002] In order to prevent bodily fluids from leaking along the user's buttocks, there are absorbent articles in which the rear region of the absorbent article is brought into close contact with the body. [0003] Japanese Patent Application Laid-Open No. 11-104169 discloses a substantially vertically elongated absorbent article in which a liquid-retentive absorbent layer is disposed on a liquid-impermeable leak-proof layer. In this absorbent article, a central portion in the longitudinal direction of the absorbent layer is fixed to the leak-proof layer, and a rear free edge portion not fixed to the leak-proof lay...
