ABSORBENT PRODUCT Russian patent published in 2022 - IPC A61F13/494 

FIELD: absorbent products.

SUBSTANCE: absorbent product (1) includes a top sheet (2), a back sheet (3) and an absorbent element (4) located between these sheets, and has a longitudinal direction (D1) corresponding to the direction from the front side to the back side of the wearer, and a width direction (D2) orthogonal to the longitudinal direction (D1). The absorbent product (1) includes a composite stretchable part (10) made with the possibility of stretching and contracting in one direction (X), and includes a first sheet and a second sheet (11, 12) and a plurality of elastic elements (13), placed between these sheets. The elastic members (13) extend along this one direction (X) and are spaced in a direction (Y) orthogonal to this one direction (X). At the places overlapping the elastic elements (13), in at least one of the first sheet and the second sheet, a plurality of high density parts (15) that do not directly connect the first sheet and the second sheet (11, 12) to each other are formed at intervals in the direction in which the elastic elements (13) extend. In the composite stretching part (10), which is in a contracted state, a wrinkled structure is formed, formed by deformation so that it has comb-like protrusions (17a) and grooves (18a), in the area of ​​the lower part of each of which there is a part (15) with high density.

EFFECT: absorbent product improvement.
