  • Patent number: 10813796
    Abstract: The present invention is intended to improve the dynamic fit of a crotch portion. The foregoing issue is solved in such a manner that a vertical stretchable part vertically extending and contracting in length is provided in a vertical intermediate portion of an absorber in a front body, an outer body of the front body has a portion overlapping at least the vertical stretchable part, width-direction both side sections of the portion, and a waist opening-side area of the portion and the sections, lifting elastic members having a contraction force of lifting a portion of the vertical stretchable part on a rear side of a front end toward width-direction both sides and an obliquely upward side at least when the diaper is worn are provided in the outer body of the front body on closer to lateral sides than to a width-direction intermediate portion of the absorber, and the vertical stretchable part vertically extends and contracts in length by elastic extension and contraction of the lifting elastic member.

  • Patent number: 10639211
    Abstract: Resilient and elastic members are sandwiched between a first sheet material and a second sheet material and overlapping areas of the first sheet material and the second sheet material are not joined together at CD direction both end portions but are joined together at an area between the both end portions, thereby to form a belt-like continuous elastic belt. The elastic belt is cut in the middle of a CD direction thereof between the resilient and elastic members at a joined position of the first sheet material and the second sheet material to form a pair of divided elastic belt. CD direction positions of these divided elastic belts are exchanged or the divided elastic belts are vertically reversed. A ventral side outer body and a dorsal side outer body are formed from the pair of divided elastic belts.
