  • Patent number: 8968263
    Abstract: An absorbent article according to the present invention includes a topsheet, a backsheet, and an absorber. The absorber has a body unit having a foreside constricted portion and a backside constricted portion, and a pair of extension units extending outside in the widthwise direction of the absorber from the body unit. An outer region is folded toward an inner region at the side of the topsheet, and the maximum length of the inner region along the longitudinal direction of the absorber is shorter than the maximum length of the outer region.

  • Publication number: 20130079743
    Abstract: In the disclosed absorbent article (1), in a front torso-surrounding region (S10A), the distance (D1) between the elastic member (100A) that is most towards leg-surrounding openings among a plurality of elastic members that extend roughly linearly in the widthwise direction (W) and the edges (E1) that are on the leg-surrounding opening (P) side of the front torso-surrounding region (S10A) is configured in a manner so as to gradually shorten and then gradually lengthen when going from both side edges (C) towards the center in the widthwise direction (W).

  • Publication number: 20120143162
    Abstract: An absorbent article according to the present invention includes leg elastic bodies and a central elastic body. An absorber has a bent part formed along a longitudinal direction. The leg elastic bodies continuously extend from one rear waistline edge to the other rear waistline edge in a state of being stretched in a width direction in a rear waistline region. The central elastic body is provided in a central portion in the width direction in a state of being stretched along the longitudinal direction, while overlapping with any one of a front waistline region and the rear waistline region in a thickness direction. At least a part of the central elastic body intersects with the leg elastic bodies while overlapping with the bent part in the thickness direction.
