Patent number: 8237012Abstract: An absorbent article having a substantially oblong shape, which is superior in liquid-proof performance and fitness, includes a liquid permeable top sheet, a back sheet, an absorbent body having elasticity disposed between the top sheet and the back sheet, and a compressed portion compressing the top sheet and the absorbent body. The compressed portion is disposed continuously to form a protrusion in a longitudinal direction to define a substantially U shape. The absorbent portion has a low elasticity portion, disposed on one part of the absorbent body, and formed so that elasticity weakens when compression to a prescribed thickness is carried out. The low elasticity portion is disposed in the vicinity of an end protruding the most in the longitudinal direction of the substantially U shape.Type: GrantFiled: September 20, 2006Date of Patent: August 7, 2012Assignee: Uni-Charm CorporationInventors: Takuya Miyama, Jun Kudo, Chiemi Habu, Kumiko Nishikawa

Patent number: 7976524Abstract: An absorbent article, in which an erroneous impression of replacement time is not given to a wearer, includes an absorbent body, a front sheet covering the absorbent body, and a rear sheet, a pair of masking members being disposed along a longitudinal direction of the absorbent body, close to two ends of a short direction of the absorbent body, the masking members being of porous film having pores continuous in the direction of thickness, the thickness thereof preferably being 0.4 mm or greater under a load of 20 g/cm2. By this means, seepage of fluid at the side margins of the front sheet is deferred and misunderstanding of replacement time by the wearer is prevented.Type: GrantFiled: January 12, 2006Date of Patent: July 12, 2011Assignee: Uni-Charm CorporationInventors: Jun Kudo, Chiemi Habu

Patent number: 7696402Abstract: An absorbent article includes a compressed groove provided on a body-side surface of a sanitary napkin includes a pair of lateral groove segments extending substantially in the longitudinal direction symmetrically about a longitudinal center line and a pair of rear groove segments converging rearward from respective rear ends of the pair of lateral groove segments so that the compressed groove as a whole presents an elongated shape which is angular rearward. The rear side groove segment has a curve conforming, in the vicinity of its rear end, with an arc of a circle having a predetermined radius and inscribed to the rear side groove segment. A bottom covering region extending rearward from the rear end of the rear groove segment has a predetermined thickness and is adapted to be folded along the longitudinal center line so that the bottom covering region can become convex on the side of the body-side surface.Type: GrantFiled: June 30, 2006Date of Patent: April 13, 2010Assignee: Uni-Charm CorporationInventors: Kumiko Nishikawa, Jun Kudo, Takuya Miyama, Chiemi Habu
