Patent No. EP4120983 (titled "Absorbent Articles And Methods Of Making") was filed by Ontex on Jan 5, 2021. The application was issued on Dec 4, 2024.
An absorbent core for hygiene articles, comprising absorbent material contained within a core wrap substrate with one or more channels substantially free of absorbent material. The channels have a length extending along a longitudinal axis and are surrounded by absorbent material. The core wrap top layer is in direct contact with the topsheet, and the top layer comprises a spunbond nonwoven or carded thermobonded nonwoven. The channels are formed by a non-porous insert in a mold, and the core wrap layers are joined together at the insert areas to create the channels.
