ABSORBENT ARTICLES FORMING A THREE-DIMENSIONAL BASIN

摘要

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.

1. An absorbent article having a wearer-facing side and a garment-facing side, and extending in a longitudinal direction and a transversal direction, the article comprising:
a topsheet on the wearer-facing side; a backsheet on the garment-facing side; an absorbent core between the topsheet and the backsheet, wherein the absorbent core comprises an absorbent layer in a core wrap, the absorbent layer comprising an absorbent material and having a longitudinally extending central portion, a first side portion disposed transversally outward of the central portion and a second side portion disposed transversally outward of the central portion on another side of the central portion; wherein the absorbent core further comprises 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; wherein 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; wherein 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 article further comprising: at least one liquid management layer between the topsheet and the absorbent core.
