Description

Technical Field

[0001] The utility model relates to an elastic structure of a comfortable diaper. Background Art

[0002] The elastic band structure of the prior art is generally as follows: a first elastic band arrangement area, a second elastic band arrangement area and a third elastic band arrangement area are arranged in sequence from top to bottom on the waistline, the first elastic band arrangement area, the second elastic band arrangement area and the third elastic band arrangement area are parallel to each other, the first elastic band arrangement area includes three first elastic bands, and the spacing between two adjacent first elastic bands is 6-6.5 mm; the second elastic band arrangement area includes seven second elastic bands, and the spacing between two adjacent second elastic bands is 8-8.5 mm; the third elastic band arrangement area includes five third elastic bands, and the spacing between the third elastic bands is 4.75-5.25 mm; this elastic band structure and arrangement method will make the elasticity of the first elastic band arrangement area, the second elastic band arrangement area and the third elastic band arrangement area different.
