ABSORBENT ELEMENT AND ABSORBENT ARTICLE Russian patent published in 2023 - IPC A61F13/536 

FIELD: absorbent products.

SUBSTANCE: absorbent element (10) has a multilayer structure formed from the first sheet (11), the first core (14), the intermediate sheet (13), the second core (15) and the second sheet (12). In the area that covers the through hole (15N) of the second core (15), when viewed from above, the second sheet (12) and the intermediate sheet (15) are closer to each other than in the area that covers the peripheral part (15M), in which no through hole is formed when viewed from above. The proportion of absorbent polymer (20) in the material forming the first core (14) is 90% of the mass. or more, and the absorbent polymer (20) is uniformly distributed at least in the area that corresponds to the crotch portion (B). In the absorbent element (10) that has absorbed the liquid, in the area that covers the through hole (15N), when viewed from above, the depth (C2D) of the recess (C2) on the side of the surface not facing the skin is not more than 40% of depth (C1D) recess (C1) on the side of the surface facing the skin.

EFFECT: absorbent element creation.
