Patent number: 8029487Abstract: An absorbent article having front, crotch and rear portions and an absorbent core of unitary construction. The core has a first region with two legs extending in the longitudinal direction of the article through at least parts of the crotch portion towards endings in the rear portion. A maximum distance between facing sides of the legs in the transverse direction is, in the crotch portion, located at a position in the longitudinal direction corresponding to a crotch point. Furthermore, the facing sides of the legs converge backwards such that a distance between them is reduced from the maximum distance to a minimum distance in the rear portion. In addition, the core has a second region surrounding the first region and the average density of the core is lower in the second region than in the first region.Type: GrantFiled: March 28, 2007Date of Patent: October 4, 2011Assignee: SCA Hygiene Products ABInventors: Anna Bagger-Sjöbäck, Evelien Beuling, Solgun Drevik
