  • 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.

  • Patent number: 11026849
    Abstract: A male incontinence guard has a fluid-impermeable backsheet, a fluid-permeable topsheet facing a user and an absorbent body arranged between the backsheet and the topsheet. The guard has a longitudinal extension along a longitudinal axis and a transverse extension along a transverse axis. The transverse axis divides the guard into an upper and a lower region. The upper region has a greater maximum extension along the transverse axis than the lower region. The absorbent body has primary and secondary cores arranged in a stacked configuration. The primary core has a greater area in an XY plane than the area of the secondary core. The secondary core has side edges that are at least partly generally parallel to the longitudinal axis. Also disclosed is a method for manufacturing the male incontinence guard.

  • 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.

  • Patent number: 10966878
    Abstract: A male incontinence guard having a fluid-impermeable backsheet, a fluid-permeable topsheet facing the user and an absorbent body arranged between the backsheet and the topsheet. The guard has a longitudinal extension along a longitudinal axis and a transverse extension along a transverse axis. The transverse axis divides the guard into an upper region and a lower region. The transverse axis extends between first and second lower corner points which define the two outermost points of the guard, which define a first width. The upper region has an inwardly recessed curvature portion extending between first and second upper corner points. The upper corner points define a second width such that the first width is greater than the second width. The corner points are connected by their respective outer side edges. A method for manufacturing a male incontinence guard is 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.

  • 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: 20200214907
    Abstract: A disposable hygiene absorbent product having a liquid-permeable topsheet of a translucent material, a liquid-impermeable backsheet and an absorbent core arranged between the topsheet and the backsheet is disclosed. The absorbent core has a smaller extension than the topsheet and the backsheet and is surrounded by a peripheral edge area which comprises the topsheet and the backsheet. The edge area has an elastic element extending longitudinally following the shape of the core and/or an outermost peripheral edge of the edge area. The backsheet has a different inherent color than the inherent color of the topsheet, the core and the elastic elements, and has a lower L*-value than the topsheet, the core and the elastic elements as measured by a reflectance spectrophotometer. The topsheet is provided with a printed pattern arranged to mask the elastic elements.

  • Patent number: 10687993
    Abstract: An absorbent hygiene article for placement in underwear is provided, including a liquid permeable topsheet, a backsheet and an absorbent core disposed between the topsheet and the backsheet. The topsheet is of a translucent material and is provided with a colored pattern defining at least one background region and at least one colored region having a first inherent color. The topsheet-facing side of the backsheet has a second color; and a background region located in an inner area has a higher L*-value than a background region located in the edge area.
