Publication number: 20040142832Abstract: A hygiene tissue is used for both cleaning and transferring lactic acid producing bacteria to the skin and urogenital area. The hygiene tissue contains, on separate parts of the tissue, cleaning liquid and a bacterial composition. Bacterial viability and transfer ability is maintained by suspending the bacteria in a lipid which protects the bacteria from moisture. The lipid also enhances transfer of the bacteria from the tissue to the skin or urogenital area. Different designs of the hygiene tissue prevent the mixing of the cleaning liquid and the bacterial composition.Type: ApplicationFiled: October 22, 2003Publication date: July 22, 2004Applicant: SCA Hygiene Products ABInventors: Bo Runeman, Ulla Forsgren-Brusk, Ingemar Fernfors

Publication number: 20040030318Abstract: Method for producing disposable diaper-pants having openable and resealable side panels. Absorption bodies are applied on a continuous web of inner or outer coversheet material so that front portions and rear portions of adjacent diaper-pants blanks in a web are directed toward each other. A continuous web of outer or inner coversheet material is applied to and secured to the web with absorption bodies. Separate side panels connected to each other by a detachable and resealable connection are secured to side portions of the adjacent front portions or rear portions of the diaper pants. Each diaper-pants blank with side panels is cut from the web and folded about a transverse axis in the crotch with the front and rear edges lying against each other. The side panels of each blank are folded toward and secured to side portions of the rear or front portion which have no side panel.Type: ApplicationFiled: March 31, 2003Publication date: February 12, 2004Applicant: SCA Hygiene Products ABInventors: Birgitta Karlsson, Johan Skogsberg, Lennart Erwast, Urban Widlund, Ingemar Fernfors

Publication number: 20030144643Abstract: An elasticized web has a gatherable substrate and a multi-strand elastic yarn affixed to the gatherable substrate at a plurality of fixation locations. So that the yarn can be affixed to the substrate without the use of an adhesive, the yarn is subjected to forces to create partial delamination of the yarn at the fixation locations and a portion of the gatherable substrate is caused to pass between the thus delaminated strands of the multi-strand elastic yarn. The elasticized web of the present invention is particularly suitable for use in disposable absorbent articles.Type: ApplicationFiled: December 26, 2002Publication date: July 31, 2003Inventors: Christian Jarpenberg, Michael Linder, Jose-Maria Mansisidor, Asa Lindstrom, Karin Lindmark, Ingemar Fernfors, Kenneth Strannemalm
