Patent number: 11633312Abstract: An absorbent article having a pair of longitudinal edges, front and rear transverse edges, a front end region, a rear end region, and a central region disposed between the front and rear end regions. The absorbent article has a liquid pervious topsheet, a liquid impervious backsheet, an absorbent core disposed between the topsheet and the backsheet, a pair of outwardly convex longitudinal central channels formed at least in the central region. The traversal distance of the pair of outwardly convex longitudinal central channels decreases towards both ends of the channels to define a central closed area.

Patent number: 8920398Abstract: An absorbent article having a pair of longitudinal edges, front and rear transverse edges, a front end region, a rear end region, and a central region disposed between the front and rear end regions. The ratio of the width of the rear end region to the width of the front end region ranges between 1:1 and 2.5:1. The absorbent article has a topsheet, backsheet, and an absorbent core disposed between the topsheet and the backsheet. The absorbent core has a pair of longitudinal edges and a pair of rear side flaps each extending laterally from the corresponding longitudinal edge of the absorbent core in the rear end region and a continuous support layer disposed on the backsheet in the rear end region. The continuous support layer includes a continuous material having a shear rigidity value of at least 3.0 gf/cm·degree in the longitudinal direction.Type: GrantFiled: November 30, 2005Date of Patent: December 30, 2014Assignee: The Procter & Gamble CompanyInventors: Tsunetoshi Miura, Yoko Munakata

Patent number: 8715258Abstract: An absorbent article having a pair of longitudinal edges, front and rear transverse edges, a front end region, a rear end region, and a central region disposed between the front and rear end regions. The absorbent article has a liquid pervious topsheet, a liquid impervious backsheet, an absorbent core disposed between the topsheet and the backsheet, and a pair of outwardly convex longitudinal central channels formed at least in the central region. The traversal distance of the pair of outwardly convex longitudinal central channels decreases towards both ends of the channels to define a central closed area. The absorbent article has a rear channel defining a rear closed area in the rear end region. The absorbent core is profiled within the central closed area so that the central region has a caliper that is greater than the caliper of the outside of the central closed area.Type: GrantFiled: November 30, 2005Date of Patent: May 6, 2014Assignee: The Procter and Gamble CompanyInventors: Yoko Munakata, Kiyoe Ohba

Publication number: 20060116653Abstract: In one aspect of the invention, the invention is directed to an absorbent article having a pair of longitudinal edges, front and rear transverse edges, a front end region, a rear end region, and a central region disposed between the front and rear end regions. The absorbent article comprises: a liquid pervious topsheet; a liquid impervious backsheet; an absorbent core disposed between the topsheet and the backsheet; a pair of outwardly convex longitudinal central channels formed at least in the central region. The traversal distance of the pair of outwardly convex longitudinal central channels decreases towards the both ends of the channels to define a central closed area which has a maximum length of 80-220 mm and a maximum width of 25-70 mm. The absorbent article further comprises a rear channel defining a rear closed area in the rear end region.Type: ApplicationFiled: November 30, 2005Publication date: June 1, 2006Inventors: Yoko Munakata, Kiyoe Ohba
