Patent number: 10369061Abstract: An absorbent product includes a liquid pervious topsheet, a liquid impervious backsheet and an absorbent core enclosed between the liquid pervious topsheet and liquid impervious backsheet. The absorbent product has in its longitudinal direction a crotch part and two end parts. The absorbent product includes at least in its crotch part an inlet material having a plurality of openings. The plurality of openings in the inlet material are formed from a plurality of slits extending in the transversal direction of the absorbent product by expanding the continuous inlet material in the longitudinal direction of the absorbent product. The liquid inlet material has in its transversal direction of the absorbent product a central region and two edge regions. The openings are located in the central region so that the central region of the material with the plurality of openings has a lesser degree of elasticity than the edge regions.Type: GrantFiled: June 10, 2015Date of Patent: August 6, 2019Assignee: ESSITY HYGIENE AND HEALTH AKTIEBOLAGInventors: Åsa Jönegren, Pia Kalentun, Susanna Edrud, Morgan Hansson, Susanne Andersson

Patent number: 6040494Abstract: The invention pertains to a foam material for absorption of aqueous liquids, a manufacturing method and an advantageous use of such a foam material, and an absorbent disposable article comprising such a foam material. The foam material is hydrophilic and primarily intended for use in absorbent disposable articles such as baby diapers, incontinence protectors and products for feminine hygiene. However, the foam material according to the invention is also suited for use in other absorbent articles, such as in different wiping materials, bandage materials and other similar products. The chemical structure of a surfactant, which is utilized as a combined emulsifying and hydrophilizing agent when manufacturing the foam material according to the invention, makes it possible to retain a sufficient proportion of the foam surfactant in the foam material even after repeated wettings, something which renders the foam material highly, permanently hydrophilic.Type: GrantFiled: May 12, 1998Date of Patent: March 21, 2000Assignee: SCA Hygiene Products ABInventors: Pia Kalentun, Anette Buschka, Andrea Schmid, Eva Strombom
