Patent number: 7458960Abstract: A pull-on disposable diaper is composed of front and rear waist covering regions and a crotch covering region and has a body fluid absorbing component extending over the crotch covering region and further extending into the front and rear waist covering regions. In the crotch covering region, the body fluid absorbing component is folded toward a center line A-A and covered with a liquid-pervious cover sheet. The cover sheet extends in the transverse direction of the absorbing component over an inner surface of the absorbing component and further extends to the side of an outer surface of the absorbing component. On the outer surface of the absorbing component, transversely opposite lateral edges of the cover sheet are folded back outward in the transverse direction. The folded-back lateral edges are joined to the inner surface of the sheet defining the crotch covering region.Type: GrantFiled: February 14, 2005Date of Patent: December 2, 2008Assignee: Uni-Charm Co., LtdInventors: Toshifumi Otsubo, Shunsuke Takino

Patent number: 7449015Abstract: A pants-type disposable wearing article includes leg-circumferential first elastic members attached to crotch region's lateral margins of an outer sheet and waist-circumferential second elastic members attached to waist regions' upper margins of the outer sheet. The elastic members are joined to the sheet while the sheet and the second elastic members are stretched at given extension ratios, respectively, in a transverse direction and the first elastic members is stretched at a given extension ratio in the leg-circumferential direction so that the sheet and the first elastic members may have substantially the same leg-circumferential dimensions after these sheet and first elastic members have been relaxed and the sheet and the second elastic members may have substantially the same transverse dimensions after these sheet and second elastic members have been relaxed. In addition, the waist regions' upper margins and the crotch region's lateral margins are substantially planar.Type: GrantFiled: May 6, 2004Date of Patent: November 11, 2008Assignee: Uni-Charm Co., Ltd.Inventors: Toshifumi Otsubo, Shunsuke Takino
