Patent number: 10966879Abstract: 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.Type: GrantFiled: May 13, 2016Date of Patent: April 6, 2021Assignee: UNICHARM CORPORATIONInventors: Takuya Inoue, Shunsuke Takino, Hideaki Maki

Patent number: 10888468Abstract: 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.Type: GrantFiled: August 16, 2016Date of Patent: January 12, 2021Assignee: UNICHARM CORPORATIONInventors: Hideaki Maki, Shunsuke Takino, Takuya Inoue

Patent number: 9023006Abstract: 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.Type: GrantFiled: September 27, 2010Date of Patent: May 5, 2015Assignee: Unicharm CorporationInventors: Shunsuke Takino, Shunsuke Masaki
