  • Patent number: 6945967
    Abstract: An absorbent product, such as a sanitary towel, includes a stiffening element (6) which is intended to contribute to the three-dimensional shape of the product during its use. The stiffening element (6) is in a plane state before use of the product and has a stiffness in the dry state of in the order of 1-15 N measured according to ASTM D 4032-82. The stiffening element has a width at the transition between the crotch portion (3) and the front portion (1) on the sanitary towel 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 and which is of the order of 15-45 mm. The product has different stiffness along a center line extending in the longitudinal direction thereof, as a result of which the product is predestined to curve in predetermined places along the center line when the product is fitted on the wearer.

  • Publication number: 20030130643
    Abstract: Absorbent article with a stiffening element to contribute to the three-dimensional shape of the article during its use. The stiffening area is planar before use and comprises a first stiffening part area in the front portion. The first stiffening part area in the front portion has a width which, at least at some point in the longitudinal direction of the article, exceeds the distance between the muscle tendons of the wearer on both sides of the crotch of the wearer in the groin. The article comprises an elongate absorbent crotch area to be fitted in the crotch of the wearer over the genitals of the latter. The absorbent crotch area is attached to the first part area and held in place by the latter so as to avoid the absorbent crotch area sliding backwards and out of the intended position over the genitals of the wearer when the wearer moves.

  • Publication number: 20030125699
    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.
