Disposable sanitary article and process for providing such article with elastic members associated with leg openings

摘要

A disposable sanitary article having elastic members extending to be associated with leg-openings secured under tension to the article along transversely opposite side edge portions 5 of the sanitary article. The transversely opposite side edge portions 5 respectively have first elastic zones A1 extending across a crotch region 21 in the longitudinal direction along a desired length, second elastic zones A2 extending from the first elastic zones A1 into a front waist region 20 along a desired length and third elastic zones A3 extending from the first elastic zones A1 into a rear waist region 22 along a desired length. The sections of the elastic members extending along the second elastic zones A2 and the third elastic zones A3 has values of stretch stress represented by a relationship of the second elastic zones < the third elastic zones or the third elastic zones < the second elastic zones.
