Patent number: 7503912Abstract: A disposable wearing article includes elastic members interposed between inner and outer sheets and attached in a stretched state to these inner and outer sheets. A base sheet constituting a component of a hook part of a mechanical fastener is oriented to extend across the elastic members and attached to the outer sheet. Of the outer sheet, a region in which the outer sheet is attached to the base sheet and peripheral regions having dimensions m, n as measured from side edges of the base sheet in a width direction of the article are attached neither to the elastic members nor to the inner sheet. The outer sheet is attached to the inner sheet in regions defined outside those peripheral regions.Type: GrantFiled: August 18, 2004Date of Patent: March 17, 2009Assignee: Uni-Charm CorporationInventors: Toshifumi Otsubo, Tomoko Sugito

Patent number: 7449016Abstract: A wearing article includes a pair of connector sheet strips extending inward from transversely opposite side edges of the wearing article and serving to connect front and rear waist regions. The connector sheet strips can be easily turned around so as to extend outward from the side edges. Each of the connector sheet strips includes a proximal end overlapped and bonded together with an inner surface of a lateral margin of the wearing article and a deformable flap portion extending inward from the proximal end in a transverse direction of the wearing article and provided with a fastener element. The proximal end bows together with the lateral margin so that the proximal end lies on the convex side and the lateral margin lies on the concave side.Type: GrantFiled: October 14, 2005Date of Patent: November 11, 2008Assignee: Uni-Charm CorporationInventor: Tomoko Sugito

Patent number: 7300427Abstract: A disposable wearing article includes connector sheet strips used to connect front and rear waist regions of the article which respectively includes proximal sections and flap-like sections. The proximal sections are fixed to the rear waist region on its inner surface along zones immediately adjacent to transversely opposite side edges of the rear waist region and the flap-like sections extend from the respective zones to the inside of the article in a circumferential direction. The flap-like sections are formed with folding guide means facilitating the flap-like sections to be folded so that these flap-like sections may extend from the inside toward the outside of the article.Type: GrantFiled: January 19, 2006Date of Patent: November 27, 2007Assignee: Uni-Charm CorporationInventors: Tomoko Sugito, Yoshio Ono

Patent number: 7288081Abstract: In a disposable wearing article, connector sheet strips for connecting front and rear waist regions of the article have proximal sections and flap-like sections. The proximal sections are fixed to the rear waist region on its inner surface along zones contiguous to transversely opposite side edges of the rear waist region. Flexural rigidity of the flap-like sections as measured in a transverse direction of the article is higher than that of the article as measured in regions lying immediately inside the respective zones which are, in turn, contiguous to the respective side edges, so that a direction in which the connector sheet strips extend can be easily reversed.Type: GrantFiled: January 19, 2006Date of Patent: October 30, 2007Assignee: Uni-Charm CorporationInventors: Tomoko Sugito, Yoshio Ono

Patent number: 7255688Abstract: A pull-on disposable wearing article has a first waist region and a second waist region. The first waist region is elastically stretch- and contractible in the transverse direction. The second waist region is formed with a pair of finger-grip zones which are non-stretchable in the transverse direction and an elastically stretch- and contractible middle zone. The finger-grip zones respectively have a dimension in a range of 10 to 100 mm as measured in the transverse direction and extend from a peripheral edge of the waist-hole to peripheral edges of the respective leg-holes, along a pair of bonded zones where transversely opposite side edges of the waist regions are bonded together. The middle zone extends between the finger-grip zones is elastically stretch- and contractible in the transverse direction.Type: GrantFiled: May 24, 2005Date of Patent: August 14, 2007Assignee: Uni-Charm CorporationInventors: Toru Sasaki, Yoshio Ono, Satoru Sakaguchi, Tomoko Sugito
