  • Patent number: 11000431
    Abstract: An absorbent article having a main body having a liquid-permeable topsheet, a liquid-impermeable backsheet and an absorbent core sandwiched between the topsheet and the backsheet is disclosed. The main body has longitudinal and transversal axes. The article has two wings extending asymmetrically outward from a crotch portion of the main body with respect to the longitudinal axis. The wings each have a means for fastening them to a garment when folded over the main body towards the longitudinal axis. The fastening means for each wing are offset from each other in the longitudinal direction. A method for manufacturing the absorbent article is also disclosed.

  • Publication number: 20200368083
    Abstract: An absorbent article having a main body that has a liquid-permeable topsheet, a liquid-impermeable backsheet and an absorbent core sandwiched between the topsheet and the backsheet is provided. The main body has mutually perpendicular longitudinal and transversal axes and front, back, and crotch portions. The article has asymmetric first and second wings extending outwardly from the crotch portion in opposite directions. The wings may be fastened to a garment when folded over the main body and towards the longitudinal axis. The wings extend along a common straight line which defines an angle with respect to the transversal axis. The angle exceeds 0° but is less than 45°. Each wing has an outer edge which is generally straight and parallel to the longitudinal axis. A method for manufacturing the absorbent article is also provided.

  • Publication number: 20200352797
    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: 10729601
    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 and a liquid inlet foam layer and the absorbent core includes a transversally central liquid inlet region extending in the longitudinal direction of the absorbent core. Within the liquid inlet region, the liquid inlet foam layer is covered by a plurality of inlet openings and has a transversal width, which is equal to, or up to 9 mm smaller than, the minimum transversal width of the absorbent fibrous layer. The liquid inlet foam layer also has side edge regions arranged in front and rear portions of the absorbent core transversally outside of the liquid inlet region, and within which the liquid inlet foam layer is free from liquid inlet openings.

  • Publication number: 20200188187
    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.

  • Patent number: 10675189
    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: 20200170849
    Abstract: Disposable hygiene article having a liquid-permeable topsheet, a liquid-impermeable backsheet and an absorbent core. The article is releasably attached to a garment and has liquid side barriers arranged substantially along longitudinal edges of the absorbent core. The article has a front portion, oriented upwards during use, having a tapering shape with a maximum width of the front portion, measured between first left and right edge points, and a minimum width, measured between second left and right edge points. A first imaginary connection line connects the first right edge point to the second right edge point and a second imaginary connection line connects the first left edge point to the second left edge point. The first and second imaginary connection lines extend in an angle ranging between 60° and 90° with the transverse direction T and have a length of at least 15% of the full length of the article.

The article has two wings, each extending outwardly from a crotch portion of the main body in opposite directions and asymmetrically with respect to the longitudinal axis. The wings have means for fastening the wings to a garment when folded over the main body. Furthermore, each wing has a first edge section and a second edge section, each extending generally alongfirst and second straight lines. The first line defines a first angle (?2) with respect to the longitudinal axis and the second line defines a second angle (?3) with respect to the longitudinal axis. The magnitude of the angles (?2, ?3) is chosen so that ?2<?3. Also disclosed is a method for manufacturing the absorbent article.
