Publication number: 20220192894Abstract: An absorbent pad having first and second longitudinal pad side edge. The absorbent pad includes a fluid permeable topsheet, a backsheet and an absorbent core. The absorbent core has first and second longitudinal side edges. The absorbent core in its longitudinal direction has a front portion, a rear portion and an intermediate portion located between the front portion and the rear portion, the front portion, the rear portion and the intermediate portion being of equal lengths. An elastic element is disposed between the fluid permeable topsheet and the backsheet outside of the respective longitudinal core side edges. A width of the absorbent core in the front portion and the intermediate portion varies no more than 25 mm along a length of the absorbent core. The respective elastic elements each extends along at least a part of the front portion and over at least 30% of the intermediate portion.Type: ApplicationFiled: May 29, 2019Publication date: June 23, 2022Applicant: Essity Hygiene and Health AktiebolagInventors: Hanna SVENSSON, Linda RÖNN, Camilla BJÖRKLUND

Patent number: 6425890Abstract: The invention relates to an absorbent article intended for female users, such as a sanitary napkin, or an incontinence guard, having such a shape and size that it may be substantially accommodated in the crotch region of a pair of panties and having a longitudinal direction, a transverse direction and a thickness direction. The article exhibits a liquid-pervious cover layer and a liquid-impervious cover layer and further an absorbent core consisting of at least one absorbent body, arranged between the two surfaces, and wherein a hump is arranged at the liquid-pervious cover layer of the article. The invention is characterized in that the hump is substantially shape permanent in the transverse direction of the article, both in a wet and in a dry state, and to such an extent that the hump (16) is not deformed in the transverse direction, either temporarily or permanently, by the forces acting on the hump during use of the article.Type: GrantFiled: September 1, 1999Date of Patent: July 30, 2002Assignee: SCA Hygiene Products ABInventors: Ann Samuelsson, Annelie Johansson, Camilla Björklund, Solgun Drevik, Urban Widlund
