Patent number: 7993314Abstract: An absorbent article, such as an incontinence shield, diaper, pant-diaper, belt diaper or the like, includes a topsheet, a backsheet and an absorbent core placed therebetween. The absorbent core has two longitudinal edges, and a front and a rear transverse edge, wherein the rear transverse edge possesses a recess with at least one pair of opposing edges. The recess forms a pocket for receiving and storing faeces, wherein the pocket's extension is defined by the edges of the recess. The article provides a simple, practical and cheap solution for handling of faeces without obviously compromising the liquid absorption properties.Type: GrantFiled: June 28, 2007Date of Patent: August 9, 2011Assignee: SCA Hygiene Products ABInventors: Fredrik Asp, Marie Johansson, Filip Jansson
