DISPOSABLE DIAPER WITH BANDS Russian patent published in 2022 - IPC A61F13/49 

FIELD: hygiene.

SUBSTANCE: invention relates to a disposable diaper. The objective consists in improving the fit of the lower edge of the winged parts when the user bends the hips. The lower edges 70 of the winged parts WP of the ventral part F have a first part 71 located on the side of the base edge and a second part 72 located on the side of the outer end. The first part 71 and the second part 72 constitute wavy parts 80 with multiple embedded recesses. In the wavy part 80 of the first part 71, the obtuse lateral crossing angle Ɵ₁ of the tangent D1 contacting both adjacent recesses 83 and the forward-backward direction LD is 160 to 175 degrees. In the wavy part 80 of the second part 72, the obtuse lateral crossing angle Ɵ₂ of the tangent D2 contacting both adjacent recesses 83 and the forward-backward direction LD is 120 to 150 degrees. The size 71y of the first part 71 in the forward-backward direction LD equals 0.15 to 0.30 of the size M_Y of the crotch part M in the forward-backward direction LD, and the size 72y of the second part 72 in the forward-backward direction LD equals 0.10 to 0.25 of the size M_Y of the crotch part M in the forward-backward direction LD.

EFFECT: creation of a disposable diaper with improved fit.
