Patent number: 10893984Abstract: An absorbent article such as a diaper comprises a topsheet, a backsheet and an absorbent core. The absorbent layer comprises at least a longitudinally-extending central portion, and a first and second side portions disposed transversally outward of the central portion. The absorbent core further comprises first and second folding guides between the central portion and the side portions. Each side portion comprises a plurality of winglets, each winglet having a proximal side relative to a folding guide and extending outward from this proximal side, and wherein neighboring winglets are separated by a gap between their neighboring sides. The central portion and the side portions form a three-dimensional basin when the absorbent core is folded along the folding guides. The article further may comprise at least one liquid management layer substantially free of superabsorbent polymer between the topsheet and the absorbent core. The absorbent core may be substantially free of cellulose fibers.Type: GrantFiled: February 16, 2016Date of Patent: January 19, 2021Assignee: The Procter & Gamble CompanyInventors: Bruno Johannes Ehrnsperger, Hans Adolf Jackels, Claus Peter Stoelzel, Sr., Christine Elisabeth Zipf

Patent number: 10456305Abstract: A package comprising a stack of absorbent articles which are bi- or tri-folded, and each article comprises a topsheet, a backsheet, and an absorbent core between the topsheet and the backsheet. The absorbent core comprises an absorbent layer comprising a central portion, a first side portion and a second side portion, a first folding guide between the central portion and the first side portion, and a second folding guide between the central portion and the second side portion. Each side portion comprises a plurality of winglets, each winglet having a proximal side relative to a folding guide and extending outward from this proximal side. Neighboring winglets are separated by a gap between their neighboring sides. When the absorbent core is folded along the folding guides, the central portion and the side portions form a three-dimensional basin and the gaps between the winglets decrease, the neighboring sides optionally coming into contact.Type: GrantFiled: February 16, 2016Date of Patent: October 29, 2019Assignee: The Procter & Gamble CompanyInventors: Bruno Johannes Ehrnsperger, Hans Adolf Jackels, Claus Peter Stoelzel, Sr., Christine Elisabeth Zipf, Roland Engel
