Patent number: 7749210Abstract: A disposable diaper has a through-hole formed in an inner sheet destined to come in contact with a wearer's skin so that this through-hole may communicate with a pocket for receiving feces. The inner sheet is formed with an elastic area extending in a longitudinal direction along transversely opposite side edges of the through-hole. In a crotch region of the diaper, a stiffening sheet strips are attached to the inner sheet between the transversely opposite side edges of the diaper and the transversely opposite side edges so that the respective stiffening sheet strips extend in a transverse direction.Type: GrantFiled: November 21, 2007Date of Patent: July 6, 2010Assignee: Uni-Charm CorporationInventors: Yoshitaka Mishima, Hironao Minato, Nariaki Shimoe

Patent number: 7666173Abstract: A disposable wearing article includes a partition provided in a front half of a crotch region divided by a transverse centerline bisecting a longitudinal dimension of the article so that the partition extends in the transverse direction on a topsheet. During use of the article, the partition curves in the transverse direction so as to describe a generally circular arc which is convex upward above the topsheet. The partition is thus spaced upward from the topsheet and the wearer's genital organ in contact with an outer surface of the partition is also spaced from the topsheet. In this way, the genital organ is protected from soiling with loose passage.Type: GrantFiled: May 27, 2005Date of Patent: February 23, 2010Assignee: Uni-Charm CorporationInventors: Yoshitaka Mishima, Kaiyo Nakajima
