  • Patent number: 10966879
    Abstract: A disposable diaper has front and rear waist regions, a crotch region, and an absorbent chassis. The absorbent chassis includes an absorbent structure and a pair of side flaps. Each of the side flaps has layered sheet materials and includes a distal edge, a cuff branch line between the side edge of the absorbent structure and the distal edge, a leg-opening elasticized area between the cuff branch line and the distal edge, and a leakage-barrier cuff branched from the cuff branch line and intersecting with the leg-opening elasticized area. The leakage-barrier cuff has a free edge parallelly-spaced from the cuff branch line. The distance from the cuff branch line to the distal edge is larger than from the cuff branch line to the free edge. The number of sheet material layers included in the leg-opening elasticized area is larger than in the leakage-barrier cuff.

  • Patent number: 10888468
    Abstract: The present invention provides a disposable wearing article which prevents a position shift of a front waist region without a part of a front waist region receding in a concave portion of the abdomen of the wearer. A plurality of linear front waist elastics contractible in a lateral direction is disposed in a front waist region of a disposable wearing article. The front waist elastics have (include) a first elastic positioned adjacent to an outer side of a front-end edge of a liquid absorbent core in a vertical direction, a second elastic positioned adjacent to an inner side of the front-end edge in the vertical direction, and a third elastic positioned adjacent to an inner side of the second elastic in the vertical direction. A contractile force of the first elastic and the second elastic is weaker than a contractile force of the third elastic.

  • Publication number: 20210001097
    Abstract: The shaft of a dilator has a tapered part whose outer diameter at a distal end is smaller than at a proximal end, and either a distal end part and a proximal end part, or a proximal end part without a distal end part. If only the proximal end part is provided, the pitch of neighboring sections of a spirally-arranged protruding portion on the tapered part is larger than that on the proximal end part. If both the proximal end part and the distal end part are provided, the pitch of neighboring sections of the spirally-arranged protruding portion on the tapered part is larger than those on the distal end part or the proximal end part.

  • Patent number: 10813795
    Abstract: Disclosed is a disposable absorbent wearing article with a given part curved to protrude outward. At least one waist region, which is at least one of front and rear waist regions in a disposable absorbent wearing article such as a pull-on diaper includes an elastic band that form a part of a skin-facing surface and extends in a lateral direction. The elastic band has a middle part in the lateral direction elastically contracting, with an elastic contraction amount of the middle part being larger than a component part of article facing the middle part without being joined to the middle part, in a thickness direction of the middle part in the lateral direction. An absorbent core material in the at least one waist region has a deformation guide extending in a direction crossing the elastic band, formed to facilitate forming of a bulging part in the wearing article.
