  • Publication number: 20190350768
    Abstract: An absorbent product includes a liquid permeable topsheet, a liquid impermeable backsheet, and an absorbent core enclosed between the topsheet and the backsheet. The absorbent core includes an absorbent fibrous layer, a liquid inlet foam layer, and a carrier layer, in which a transversally central region is arranged in the liquid inlet foam layer. The transversally central region extends along the entire longitudinal length of the absorbent core and includes a plurality of slits arranged in a pattern, wherein the slits are dilated slit openings in a part of the central region within an intermediate portion of the absorbent core, and the slits are non-dilated slits in parts of said central region within one or both of front and rear portions of the absorbent core.

  • Publication number: 20140142528
    Abstract: An absorbent pad having a chassis including a liquid-permeable topsheet and a liquid-impermeable backsheet, wherein the absorbent pad is geometrically symmetrical along its longitudinal and transversal centre lines. The absorbent pad is provided with attaching arrangements by which the pad can be releasably attached to a separate belt adapted to be placed around the waist of the user. The absorbent pad further includes an absorbent core interposed between the topsheet and backsheet, so that the absorbent core is divided into a first longitudinal half and a second longitudinal half along its longitudinal length. The absorbent core has a thickness which is substantially the same on the same distance from the transversal centre line (measured perpendicular to the transversal centre line) before the core is wetted. The first longitudinal half has a higher absorption capacity than the second longitudinal half.

  • Patent number: 6652499
    Abstract: Absorbent product such as an incontinence pad, sanitary pad, diaper, absorbent inlay or the like, having a central absorbent portion with an upper permeable surface. The absorbent product also has a fluid-impermeable backsheet. In order to provide width adaptation and to allow a basin-shape to be formed in the product, two lateral portions are provided. Each of the lateral portions extends in the longitudinal direction of the product. The inner edge of each lateral portion is attached to the central portion by means of a surplus of material and the outer edge is a free outer edge. The lateral portions can thus move in a lateral direction independently of a central portion.

  • Patent number: 6629967
    Abstract: An absorbent article includes a liquid-permeable upper sheet, a liquid impermeable bottom sheet, and an absorbent body between the bottom sheet and the upper sheet, and at least one longitudinally extending liquid barrier comprising an elongated elastic element and an elongated, essentially liquid-impermeable and inelastic material on each side of a longitudinal center line. A liquid impermeable top sheet with an aperture intended to lie in register with a wearer's anus and urethral orifice may also be included. A prestretched elastic band is attached to either an edge of an inelastic material of the liquid impermeable barrier or to the aperture-defining edge of the liquid permeable top sheet. When the article is donned, the elastic device will lie against a wearer, with a free part facing toward the longitudinal center line and a stretchable, puckered sealing edge facing outward from the longitudinal center line.

  • Patent number: 6503238
    Abstract: An absorbent article suitable for use as a diaper or adult incontinence garment includes an absorbent body disposed between a cover sheet, an inner sheet. Longitudinally extending folds disposed on the inner sheet inhibit the leakage of bodily exudates from the edges of the article. Elastic members extend along a portion of the length of the folds in the mid portion of the article. In the back portion of the article, elastic members connected to the inner sheet extend adjacent the edges of the absorbent body to enhance the fit of the garment. In the front portion of the article, elastic members may also be connected to the inner sheet and extend adjacent the edges of the absorbent body to enhance the fit of the garment.
