ABSORBING PRODUCT Russian patent published in 2023 - IPC A61F13/534 

FIELD: absorbents.

SUBSTANCE: absorbent element (5) has a multilayer structure (8) consisting of a first layer (6) in which a stack of fibrous material provides support for the absorbent polymer (P) and a second layer (7) in which the absorbent polymer (P) is placed between two base sheets (71). The second layer (7) has at least in the crotch part (B) crotch protrusions (7E1) projecting outward in the lateral direction (Y) from the side edges of the first layer (6) extending along the longitudinal direction (X), and the crotch protrusions (7E1) undergoing compression are made with the possibility of bending along the side edges of the first layer (6) when the crotch part (B) is compressed in the lateral direction (Y) between the legs of the wearer wearing the absorbent article (1). At least in the crotch part (B) in the zone (70) coinciding in the longitudinal direction (X) with the crotch protrusions (7E1), the first layer (6) has a higher surface density of the absorbent polymer than the second layer (7), and the second layer (7) has a higher absorbent polymer density than the first layer (6).

EFFECT: enhancement of absorbtion.
