  • Patent number: 10369061
    Abstract: 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.

  • Publication number: 20180338869
    Abstract: Absorbent product includes a liquid permeable topsheet, a liquid impermeable backsheet, and an absorbent core enclosed between the topsheet and the backsheet, wherein the absorbent core includes a liquid inlet foam material located closest to the liquid pervious topsheet and an absorbent fibrous layer located closest to the impervious backsheet. The liquid inlet foam material has in the transversal direction of the absorbent product two edge regions and one central region located between the edge regions. The central region has a plurality of openings formed from a plurality of slits extending in the longitudinal direction of the absorbent product and that openings have been formed from the slits by expanding the continuous liquid inlet foam material in the transversal direction of the product, and that each edge region of the liquid inlet foam material has a width that is at least 5.0 mm and is free from openings.

  • Publication number: 20100249738
    Abstract: An absorbent article comprises a liquid impermeable backsheet and an absorbent core. The backsheet is not overlaid by the core in at least one margin section. The article also comprises at least one ventilation component constituted by a ventilation material. Each ventilation component is positioned overlaying the backsheet and exclusively localized within one or more margin sections. The thickness of the ventilation material measured at 0.5 kPa is at least 1 mm. The porosity of the ventilation material is >80%. The ratio between the thickness of the ventilation material measured at 5 kPa and the thickness of the ventilation material measured at 0.5 kPa is >0.5. Each ventilation component is arranged such that an associated spacing is created between the wearer's skin and the backsheet when the absorbent article is worn.

  • Patent number: 6040494
    Abstract: 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.
