Patent number: 7368627Abstract: An absorbent article has a liquid pervious user-facing first side including a liquid-pervious surface layer composed of hydrophobic material, a second side opposite the first side and including a liquid-impervious surface layer, and an absorbent body enclosed between the two surface layers. The first side further exhibits a wetting region, which is the region of the first side intended to first be wetted by body fluid emitted to the article. The wetting region is constituted of a hydrophilic material. An outer edge portion of the wetting region is bordered by the hydrophobic material of the liquid pervious surface layer which is situated laterally outwardly of the wetting region.Type: GrantFiled: February 3, 1998Date of Patent: May 6, 2008Assignee: SCA Hygiene Products ABInventor: Urban Widlund

Patent number: 7204390Abstract: A stack of material sheets, which material sheets have a longitudinal direction and a transverse direction and which material sheets are folded at least once in the transverse direction along a transverse folding line and at least once in the longitudinal direction along a longitudinal folding line. The material sheets are interlinked such that, when a first material sheet is extracted, a predetermined part of the next material sheet is fed out. Two consecutive material sheets in the stack are folded into one another and are in this way interlinked by panels of the respective material sheets. The said panels constitute rectangles each having two delimiting edges namely a longitudinal fold edge and a transverse fold edge. The two consecutive material sheets lie stacked with the longitudinal fold edge of a first material sheet arranged in the opposite direction in relation to the corresponding longitudinal fold edge of the next, second material sheet.Type: GrantFiled: April 13, 2004Date of Patent: April 17, 2007Assignee: SCA Hygiene Products ABInventor: Urban Widlund

Patent number: 7156832Abstract: 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.Type: GrantFiled: December 6, 2002Date of Patent: January 2, 2007Assignee: SCA Hygiene Products ABInventors: Solgun Drevik, Fredrik Asp, Urban Widlund, Elisabeth Boissier

Patent number: 6960197Abstract: Absorbent pants having a waist opening, two leg openings, and a waterproof outer barrier layer, which is arranged outside the pants layer. The pants layer has a surface area which is greater than that of the outer barrier layer and is joined in parts with itself or includes a device for enabling it to be joined in parts with itself, so that during use of the pants it alone constitutes the waist opening and the leg openings of the pants, and that the load-bearing parts of the pants and all of the parts lying against the body of the user are formed only from the pants layer. The pants are also elastic, where the outer barrier layer is essentially inelastic.Type: GrantFiled: February 1, 1996Date of Patent: November 1, 2005Assignee: SCA Hygiene Products ABInventors: Anders Gustafsson, Urban Widlund

Patent number: 6835192Abstract: An absorbent article such as a diaper or an incontinence protector, comprising at least one liquid storage region (2, 3) with high absorption capacity and at least one wicking layer (4) which overlaps at least a substantial part of the liquid storage region and which has greater liquid dispersion ability than the storage region. The wicking layer (4) is intended to disperse liquid collected locally in the article over the liquid storage region (2, 3). The aim of the invention is to improve liquid dispersion in absorbent articles. The invention is characterized in that liquid-impermeable portions (5, 6) are arranged at separate places in the article along sections of overlapping parts of the wicking layer (4) and the liquid storage region (2, 3) in order to prevent the transfer of liquid over said parts from the wicking layer to the storage region.Type: GrantFiled: January 29, 2002Date of Patent: December 28, 2004Assignee: SCA Hygiene Products ABInventors: Ted Guidotti, Roy Hansson, Urban Widlund, Gunnar Edwardson, Peter Blomström, Eje Österdahl

Patent number: 6817484Abstract: The invention relates to a container for a stack of interfolded tissue sheets. The container has a generally planar bottom wall and a top wall and side walls connecting the bottom wall with the top wall. An opening is provided in the top wall for the removal of the tissue-sheets from the container, which opening is wider than the width of the tissue-sheets. The stack of interfolded tissue-sheets is placed in the container with a lowermost tissue-sheet placed on the bottom wall and an uppermost tissue-sheet placed near or in contact with the top wall and adjacent to the opening in the top wall. The opening is provided with a positioning feature having elongated, overlapping projections extending from opposite sides of the opening in order to allow the uppermost tissue-sheet to be dispensed, holding it substantially flat. The invention also relates to a method for producing the positioning feature.Type: GrantFiled: October 26, 2001Date of Patent: November 16, 2004Assignee: SCA Hygiene Products GmbHInventors: Emmanuelle Morin, Urban Widlund
