Patent number: 11944526Abstract: An absorbent core, for use in an absorbent article, including a core wrap enclosing an absorbent material and including superabsorbent polymer particles. The core wrap includes a top side and a bottom side, and the absorbent core includes one or more area(s) substantially free of absorbent material through which the top side of the core wrap is attached to the bottom side of the core wrap, so that when the absorbent material swells the core wrap forms one or more channel(s) along the area(s) substantially free of absorbent material. The superabsorbent polymer particles have a time to reach an uptake of 20 g/g (T20) of less than 240 s as measured according to the K(t) test method.Type: GrantFiled: September 23, 2021Date of Patent: April 2, 2024Assignee: The Procter & Gamble CompanyInventors: Andrea Andrew Peri, Aniruddha Chatterjee, Peter Dziezok, Bruno Johannes Ehrnsperger, Juliane Kamphus, Marion Lutsche

Publication number: 20220031527Abstract: An absorbent article comprising a liquid permeable topsheet, a backsheet, an absorbent core comprising an absorbent material and a core wrap is provided. The core comprises at least one channel-forming area that is substantially free of absorbent material. The absorbent article comprises a masking layer between the bottom side of the core wrap and the backsheet. The masking layer and the bottom side of the core wrap are only partially bonded to each other at their interface, the interface thus comprising a bonded portion and an unbonded portion, wherein the channel-forming area at least partially corresponds to the unbonded portion of the interface, so that when the absorbent material swells, the masking layer can decouple from the three-dimensional channels.Type: ApplicationFiled: July 27, 2021Publication date: February 3, 2022Inventors: Ernesto Gabriel BIANCHI, Matthias Konrad HIPPE, Aniruddha CHATTERJEE, Adrien GRENIER, Andrea PERI, Udo Friedel SCHOENBORN, Abhishek Prakash SURUSHE
