  • 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: 11197784
    Abstract: An absorbent disposable article, such as a diaper, panty diaper, panty liner, sanitary napkin or incontinence device is disclosed. The article has a porous polymer-based structure obtainable by a process of: (a) depositing and photopolymerizing, layer-by-layer in accordance with a predetermined 3D model, an emulsion having an external continuous phase surrounding droplets of an internal phase having has one or more photopolymerizable monomers and/or oligomers and a photopolymerization initiator; and (b) removing the internal phase from the continuous polymer phase formed from the one or more photopolymerizable monomers and/or oligomers. The process produces a monolithic porous structure having three types of pores: (i) pores resulting from the location from which the internal phase was removed, (ii) pores interconnecting the pores according to (i), and (iii) pores as predetermined by the 3D model. The invention also relates to a method of making the article.
