  • 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.

  • 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.

  • Patent number: 10064765
    Abstract: A wearing article including cover sheets used to cover front and rear ends of a liquid-absorbent structure and improved to alleviate undesirable irritation due to such cover sheets potentially experienced by the wearer. A diaper includes front and rear waist members and a liquid-absorbent structure by which the front and rear waist members are connected. The liquid-absorbent structure has front and rear ends overlapping the front and rear waist members, and front and rear cover sheets are laminated on these front and rear ends to cover them. The front and rear cover sheets are formed with bonded regions adapted to be bonded to the liquid-absorbent structure or the front and rear waist members, outside non-bonded regions lying outboard of the bonded regions and inside non-bonded regions lying inboard of the bonded regions. The inside non-bonded regions are respectively folded back along fold lines toward the wearer's body to form turnbacks.

  • Patent number: 9023006
    Abstract: The present invention aims to provide a wearing article adapted to prevent unintentional displacement of a crotch region relative to front and rear waist regions by elastics attached to the crotch region. A diaper includes front and rear waist members, a crotch member by the intermediary of which the front and rear waist members are connected with each other. The rear waist member is formed with a waist fit section and an appendix section. Of the crotch member, front and rear ends including front and rear end flaps are bonded to the front and rear waist members, respectively, to form front and rear bonded regions. Both side flaps are provided on respective inner surfaces thereof with gasket elastics attached thereto. Each of the gasket elastic overlaps at one end with a part of the front waist elastic and overlaps at the other end with a part of the appendix section elastic. Furthermore, the one end overlaps with the front bonded region and the other end overlaps with the rear bonded regions.
