STRETCHABLE STRUCTURE FOR ABSORBENT PRODUCT AND DISPOSABLE DIAPER OF UNDERWEAR TYPE Russian patent published in 2019 - IPC A61F13/49 

Abstract RU 2706413 C2

FIELD: medicine; hygiene.

SUBSTANCE: solution: stretchable structure of absorbent product includes two sheet layers 12S and 12H, which pass in stretching direction and orthogonal direction, orthogonal to stretching direction; and elongated elastic and elastic elements 19, which are located between sheet layers 12S and 12H with given intervals in orthogonal direction and extend in the stretching direction, wherein two ends in expansion direction of each of elastic and elastic elements 19 include fixed ends 19f, attached to two sheet layers 12S and 12H, and section between fixed ends 19f includes free section 19m, not attached to two sheet layers 12S and 12H, at least one sheet connecting sections 20 is located in at least one separating free section of FA area, defined between free sections 19m, adjacent to each other in orthogonal direction, wherein two sheet layers 12S and 12H are connected in at least one separating free sections of FA, and two sheet layers 12S and 12H in a compressed state correspond to each other in a wavy pattern in response to compression of elastic and elastic elements 19.

EFFECT: achieving a softer tactile feeling of the product in an unstretched condition.

14 cl, 28 dwg
