Patent number: 7708725Abstract: A sanitary napkin that is provided with large rear flaps to effectively prevent liquid from leaking obliquely rearward. The rear flaps are disposed rearward of fold-back flaps to be wrapped around a crotch part of an undergarment. The rear flap is of a shape spreading rearwardly from a starting point. With a pressure from the thighs acting forward of the starting point, leakage preventing walls forward of the starting point can be maintained in a rising state during wear. On the other hand, the leakage preventing walls rearward of the starting point may possibly fall outward. However, even if the leakage preventing walls fall outward rearward of the starting point, they will never project out of the rear flaps. Accordingly, they hardly leave a stain on an undergarment.Type: GrantFiled: June 7, 2004Date of Patent: May 4, 2010Assignee: Uni-Sharm CorporationInventors: Noritatsu Tamagawa, Masataka Kinoshita, Kazuya Nishitani, Toshiyuki Tanio

Patent number: 7618404Abstract: A disposable absorbent article includes two laterally opposing longitudinally extending backsheet strips attached to an exterior surface of an absorbent assembly in laterally opposing attachment zones. Each backsheet strip may include a water-impermeable layer and may be extensible. The absorbent assembly includes a lower covering sheet that is doubled by folding and thereby includes a first layer and a second layer. The absorbent assembly also includes laterally opposing side flaps which are formed by folding doubled portions of the lower covering sheet laterally inward. A longitudinally extending elastic gathering member is attached to each side flap adjacent to its proximal edge. When the article is worn, the elastic gathering members contract and raise the side flaps to form side barriers.Type: GrantFiled: June 23, 2005Date of Patent: November 17, 2009Assignee: The Procter & Gamble CompanyInventors: Gary Dean LaVon, Kevin Michael Smith

Patent number: 7588561Abstract: A pull-on disposable wearing article is formed in a crotch region with first and second pairs of folding guide lines extending from first and second waist lateral margins toward a transverse middle of the crotch region, respectively. The crotch region is divided into a first zone enclosed by the first waist lateral margin and the first folding guide lines, a second zone enclosed by the second waist lateral margin and the second folding guide lines and a third zone outside the first and second zones. Inside the side edges of the core, first and second elastic members are contractible attached to the article. The first and second elastic members extend across the first and second zones to the third zone. The first and second zones are pulled inward under contractile forces of the elastic members to form tucks which are convex inwardly of the leg-holes.Type: GrantFiled: January 9, 2004Date of Patent: September 15, 2009Assignee: Uni-Charm CorporationInventors: Yasuhiko Kenmochi, Takaaki Shimada, Takako Uosawa, Toshifumi Otsubo
