  • Patent number: 8430858
    Abstract: An absorbent article having a waistband which is attached to first and second body portions of the article. The first body portion is attached to the waistband by at least a fastening means wherein the article assumes a pant diaper form. The waistband has a reception surface and a perforation. The perforation allows the reception surface to be separated into first and second belt portions. At least a part of the reception surface is located on each belt portion, thereby allowing the article to assume a belt diaper form. The first belt portion comprises at least one fastening means. The second fastening means is arranged so that the absorbent article can be readily converted from a pant diaper form to a belt diaper form.

  • Patent number: 8353889
    Abstract: A hygienic article having side panels extending outward in a lateral direction from either of said front or back waist region. Each side panel comprises at least two material segments which are connected to each other by a lap seam wherein said material segments define a distal segment and a proximal segment in the lateral direction. On the distal edge of each side panel a fastening member is placed which is capable of securing said side panels to the front or back waist region such that the hygienic article assumes a pant like shape. The material segments which form the side panels are attached to each other by the lap seam in such a way that when the side panels are folded back towards the longitudinal centerline of the hygienic article, the materials are attached to each other in the lap seam such that the most distal material segment is placed closer towards the inner or outer surface of the hygienic article than the more proximal material segment attached to said most distal segment.
