Patent number: 11197784Abstract: 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.Type: GrantFiled: July 6, 2017Date of Patent: December 14, 2021Assignee: ESSITY HYGIENE AND HEALTH AKTIEBOLAGInventors: Philip Blomström, Peter Rönnberg, Kent Vartiainen, Axel Eriksson, Harald Wutzel

Patent number: 11026849Abstract: 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.Type: GrantFiled: July 7, 2017Date of Patent: June 8, 2021Assignee: ESSITY HYGIENE AND HEALTH AKTIEBOLAGInventors: Marcus Rudén, Peter Rönnberg

Patent number: 10966878Abstract: 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.Type: GrantFiled: June 14, 2017Date of Patent: April 6, 2021Assignee: ESSITY HYGIENE AND HEALTH AKTIEBOLAGInventors: Marcus Rudén, Peter Rönnberg, Stina Lindlöf
