DISPOSABLE PRODUCT FOR WEARING Russian patent published in 2022 - IPC A61F13/49 

Abstract RU 2774800 C1

FIELD: disposable products.

SUBSTANCE: disposable product for wearing has stretchable structure (20X) with an elastic sheet, in which first sheet layer (20A) ad second sheet layer (20B) are connected by means of connection holes (31) passing through elastic sheet (30) in a set of connected parts located at intervals. At the same time, on part of elastic sheet (30) located in stretchable zone (80), first pattern (51) is printed, on part of elastic sheet (30) located in non-stretchable zone (70), second pattern (52) is printed. First pattern (51) and second pattern (52) are the same, when stretchable zone (80) and non-stretchable zone (70) are in a state corresponding to the relative elongation at the elasticity limit. A size of elements of a pattern, which is first pattern (51), determined in the direction of stretching, at a stretching degree of stretchable area (80) of 130% or more, is 80% or more of a size of elements of a pattern, which is first pattern (51), determined in the direction of stretching, when stretchable zone (80) is in a state corresponding to the relative elongation at the elasticity limit.

EFFECT: reduction in the difference in the appearance of a pattern between a stretchable zone and a non-stretchable zone, when wearing.
