Publication number: 20140296813Abstract: The subject of the invention is a wound care article for extraction and control of wound fluids, comprising at least one first fluid-absorbing structure (1; 10; 36), which is surrounded by a liquid-permeable, first enclosure (2), and a liquid-permeable, second enclosure (3) comprising two enclosing surfaces (13.1, 13.2). The wound care article is thus characterized in that the first enclosure (2) is covered or supported on at least one of its flat sides (4.1, 4.2) by at least one fluid-absorbing material layer (6.1, 6.2; 6.3), which is arranged (FIG. 1a) between the first enclosure (2) and one of the enclosing surfaces (13.1, 13.2) of the second enclosure (3).Type: ApplicationFiled: March 18, 2014Publication date: October 2, 2014Inventor: Birgit Riesinger

Patent number: 8841506Abstract: The present invention relates to disposable absorbent articles such as sanitary napkins, panty liners, baby diapers, adult incontinence articles and sweat pads. According to the present invention the absorbent article in the region designated for liquid deposition on its wearer facing surface has a single layer topsheet onto which liquid to be absorbed is provided during use of the article. The absorbent article includes a backsheet forming the liquid barrier surface and a unitary absorbent core between the topsheet and the backsheet. Importantly the unitary core provides improved liquid handling to the absorbent article and increases the masking, i.e. ability to hide stains due to absorbed liquid, of the article. This is particularly beneficial in the context of articles for absorption of liquids with high color intensity, such as menstrual liquid or urine of older adults.Type: GrantFiled: May 14, 2013Date of Patent: September 23, 2014Assignee: The Procter & Gamble CompanyInventors: Pietro Febo, Luigi Marinelli
