UNDERPANTS TYPE DISPOSABLE WEARING ARTICLE

摘要

A pants-type disposable wearing article 1 includes leg-circumferential first elastic members 3 attached to crotch region's lateral margins 15 of an outer sheet 2 and waist-circumferential second elastic members 4 attached to waist regions' upper margins 13 of the outer sheet 2. The elastic members 3, 4 are joined to the sheet 2 while the sheet 2 and the second elastic members 4 are stretched at given extension ratios, respectively, in a transverse direction and the first elastic members 3 is stretched at a given extension ratio in the leg-circumferential direction so that the sheet 2 and the first elastic members 3 may have substantially the same leg-circumferential dimensions after these sheet 2 and first elastic members 3 have been relaxed and the sheet 2 and the second elastic members 4 may have substantially the same transverse dimensions after these sheet 2 and second elastic members 4 have been relaxed. In addition, the waist regions' upper margins 13 and the crotch region's lateral margins 15 are substantially planar.
