  • Patent number: 11950989
    Abstract: Disposable hygiene article comprising a liquid-permeable topsheet, a liquid-impermeable backsheet and an absorbent core, flexible side flaps arranged on opposite sides of the absorbent core for attaching the article to a garment, and liquid side barriers arranged substantially along longitudinal edges of the absorbent core. The flexible side flaps each comprise at least a side layer which is secured to the topsheet by means of a seam, the seam partitioning the side layer in a first part and a second part with the first part extending from the seam towards the longitudinal centre axis and the second part extending from the seam away from said longitudinal centre axis. The first parts form the liquid side barriers.

  • Patent number: 11141323
    Abstract: A disposable hygiene article having an absorbent core with a first region which has its narrowest width (M) in the transverse direction (x) in a front portion or at a location of a transition between the front portion and a crotch portion of the article. The absorbent core comprises a high-density first region and a low density second region. The absorbent core in the crotch region has first and second rear compression lines. The compression lines mutually diverge in a direction towards the core front edge. Each line has a diverging angle (?2; ?3) of from 15-60° with respect to a centre line (A). The second region has an average density which is at least 20% lower than the average density of the first region.

  • Patent number: 8901368
    Abstract: An absorbent core for use in an absorbent product, such as a sanitary napkin, a diaper, an incontinence protection or the like. The core after compression has a material density (based on the total content of the core) of at least 200 kg/m3, preferably at least 230 kg/m3, measured at a pressure of 0.5 kPa. The absorbent core has been formed in-line as a discrete or continuous core and includes SAP-particles, where at least 99.5% of the SAP-particles have a size of maximally 600 ?m. Hereby, problems with regard to clogging of SAP-particles to compression rollers during manufacturing are markedly reduced. Further, a method for manufacturing the absorbent core, as well as an absorbent product including the absorbent core is described.

  • Patent number: 8029487
    Abstract: An absorbent article having front, crotch and rear portions and an absorbent core of unitary construction. The core has a first region with two legs extending in the longitudinal direction of the article through at least parts of the crotch portion towards endings in the rear portion. A maximum distance between facing sides of the legs in the transverse direction is, in the crotch portion, located at a position in the longitudinal direction corresponding to a crotch point. Furthermore, the facing sides of the legs converge backwards such that a distance between them is reduced from the maximum distance to a minimum distance in the rear portion. In addition, the core has a second region surrounding the first region and the average density of the core is lower in the second region than in the first region.
