The invention relates to a disposable absorbent pant comprising a central chassis and elasticized front and rear belt. The central chassis comprises an absorbent core with an absorbent layer. The absorbent layer comprises a continuous channel formed therein.

Absorbent pant having an absorbent core with continuous channel

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. The articles in the package are either bi-folded along a transversal fold line and are compressed at an In-Bag Compression Rate of from 5% to 50%, or the articles are tri-folded along a first fold line and a second fold line parallel to the transversal direction.

Package for absorbent articles forming a three-dimensional basin

An absorbent core includes a core wrap having a top layer and a bottom layer enclosing superabsorbent polymer. The absorbent core is substantially free of cellulose fibers. The absorbent layer comprises a non-rectangular central portion having a front edge, a back edge and two longitudinally-extending side edges. Each side edge defines a recess along a portion of its length; a first side portion present in one of the recess and a second side portion present in the other recess. The proximal edges of the side portions are convex; and either the distal edges of the side portions are concave so that the side portions are crescent-shaped; or the distal edges of the side portions is straight. The absorbent core further includes a first and second folding guide, and when the absorbent core is folded along the folding guides, the central portion and the side portions form a three-dimensional basin.

Absorbent cores for absorbent articles

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.

Absorbent articles forming a three-dimensional basin

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 curved 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 absorbent core is substantially free of cellulose fibers. The article further may comprise at least one liquid management layer substantially free of superabsorbent polymer between the topsheet and the absorbent core.
