Absorbent article having low rigidity sections
First Claim
1. An absorbent article having a width and a length orthogonal to the width, comprising:
- a chassis having at least a front torso surrounding region and a rear torso surrounding region arranged along a longitudinal direction of the absorbent article;
a crotch region positioned between the front torso surrounding region and the rear torso surrounding region in the chassis;
an oblong absorbent body provided extending from the front torso surrounding region to the rear torso surrounding region along the longitudinal direction, the absorbent body comprising an absorbent core covered with a cover sheet;
a pair of stretchable sheets arranged at both outer side edges of the cover sheet with respect to the width direction and extending in the longitudinal direction, an outer edge of each of the stretchable sheets being formed to have an arch portion that recesses toward a center line of the absorbent body at a center portion in the longitudinal direction of the stretchable sheets;
a torso opening section formed at one side when in a wearing mode;
a pair of leg openings formed at another side when in the wearing mode;
a skin-contacting face facing an inner face when in the wearing mode;
a not-skin-contacting face facing an outer face when in the wearing mode; and
an elastic member arranged along a side edge extending in a longitudinal direction of the crotch region constituting the leg opening, whereinthe absorbent core includes;
a first narrow width section;
a second narrow width section arranged longitudinally spaced from the first narrow width section;
a center low rigidity section formed along a center line that halves the absorbent article in the width direction of the absorbent article; and
a pair of lateral low rigidity sections provided at both sides of the center low rigidity section in the width direction of the absorbent article with a substantially equal interval;
whereinthe cover sheet has at a skin contacting side a length in the width direction that is longer than a length of the absorbent core in the width direction so that the cover sheet at the skin contacting side is loosened, and at the skin contacting side, the cover sheet is entirely free of joining with the absorbent core from one end to another end in the width direction of the absorbent core, andthe stretchable sheet has a narrowest width at the arch portion, and a portion of the stretchable sheet that has the narrowest width at the arch portion extends outward over the outer side edge of the cover sheet at the arch portion, and the outer edge of the stretchable sheet extends over the outer side edge of the cover sheet along an entire length of the stretchable sheet in the longitudinal direction of the absorbent core,the absorbent article is a diaper for an adult.

Abstract
The absorbent article includes a chassis, a crotch region, an absorbent body, and an elastic member arranged along a side edge in width direction of the crotch region. The oblong absorbent body arranged in the crotch region includes a first narrow width section, a second narrow width section, a center low rigidity section formed along a center line that halves the absorbent article in the width direction and a pair of lateral low rigidity sections provided at both sides of the center low rigidity section in the width direction with a substantially equal interval. Skin contacting face-side sheets and non-skin contacting face-side sheets 6 and 10 are arranged in the crotch region. The initial tensile strength of the skin contacting face-side sheets is lower than that of the non-skin contacting face-side sheets or that of the chassis 2.
