Patent PL-192330-B1 (PL)
Title: Panty liner
Inventor: GUSTAFSSON ANDERS
IPC: A61F13/15
Filed: 1998-05-13
Abstract: An absorbent article with an absorbent body enclosed between inner and outer casing sheets and a stiffening element extending from the rear, through the intermediate, and into the front part of the article. The stiffening element's front and rear parts are broader than its intermediate part and the stiffening element is not wider than 4 cm at its front to intermediate transition region. Side flaps are formed by at least some parts of the remainder of the article which extend laterally beyond the stiffening element, so that the distance between side-edges of the stiffening element and an edge of the side flap varies within the region. The stretch resistance of the side flaps is greater than the stiffening element's longitudinal bending resistance, so inward pressing of the side flaps causes the stiffening element to curve longitudinally, to obtain an upwardly concave shape adapted to the shape of a wearer's body.
