  • Patent number: 7993314
    Abstract: 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.

  • Patent number: 7316673
    Abstract: An absorbent product includes a stiffening element intended to contribute to the three-dimensional shape of the product during its use. The stiffening element is in a plane state before use of the product and extends in the longitudinal direction of the product over the crotch portion and at least some way in over the front portion. The stiffening element has a width at the transition between the crotch portion and the front portion which is adapted to the distance between the muscle tendons of the wearer on both sides of the crotch of the wearer in the groin of the latter. The side edges of the stiffening element in the front portion of the product diverge in the direction from the crotch portion at least some way in over the front portion and form an acute angle with a line in the longitudinal direction of the product.

  • Patent number: 7156832
    Abstract: Absorbent article, such as a sanitary towel, with a stiffening element which is intended to contribute to the three-dimensional shape of the article during its use. The stiffening element is in a plane state before use of the article. The stiffening element has in the rear portion an elongate through-hole which extends in the longitudinal direction of the article and along the centre line of the article, as a result of which the article is during use provided, by virtue of lateral forces arising in the rear portion of the article, with a fold along the longitudinal direction of the article along the hole. The fold extends into the cleft between the buttocks of the wearer during use of the article and in this way stabilizes the article in position on the wearer.
