  • Patent number: 11944526
    Abstract: An absorbent core, for use in an absorbent article, including a core wrap enclosing an absorbent material and including superabsorbent polymer particles. The core wrap includes a top side and a bottom side, and the absorbent core includes one or more area(s) substantially free of absorbent material through which the top side of the core wrap is attached to the bottom side of the core wrap, so that when the absorbent material swells the core wrap forms one or more channel(s) along the area(s) substantially free of absorbent material. The superabsorbent polymer particles have a time to reach an uptake of 20 g/g (T20) of less than 240 s as measured according to the K(t) test method.

  • Patent number: 11439544
    Abstract: A package comprising a stack of absorbent articles which are bi- or tri-folded, and each article comprises a topsheet, a backsheet, and an absorbent core between the topsheet and the backsheet. The absorbent core comprises an absorbent layer comprising a central portion, a first side portion and a second side portion, a first folding guide between the central portion and the first side portion, and a second folding guide between the central portion and the second side portion. Each side portion comprises a plurality of winglets, each winglet having a proximal side relative to a folding guide and extending outward from this proximal side. Neighboring winglets are separated by a gap between their neighboring sides. When the absorbent core is folded along the folding guides, the central portion and the side portions form a three-dimensional basin and the gaps between the winglets decrease, the neighboring sides optionally coming into contact.

  • Patent number: 11273086
    Abstract: An absorbent article for personal hygiene comprising a liquid permeable topsheet, a liquid impermeable backsheet, an absorbent core and a fibrous layer. The absorbent core comprises a core wrap and an absorbent material with superabsorbent polymers. The core wrap comprises a top side and a bottom side bonded to one other through one or more areas substantially free of absorbent material. The fibrous layer is at least partially bonded to one of the sides of the core wrap in the area substantially free of absorbent material. When the absorbent material swells, the core wrap forms one or more channels along the area substantially free of absorbent material. The formation of the channel in the absorbent core causes the formation of one or more corresponding ditches in the fibrous layer.
