DISPOSABLE PANTTYPE DIAPER HAVING IMPROVED FITNESS TO BODY

摘要

The present invention is directed to a disposable pull-on garment having a longitudinal center line, a front region, a back region and a crotch region between the front region and the back region. The disposable pull-on garment includes a chassis provided in the front, back and crotch regions. The chassis has edge lines in the front and back regions and includes a liquid pervious topsheet, a liquid impervious backsheet associated with the topsheet, and an absorbent core disposed between the topsheet and the backsheet. The disposable pull-on garment further includes at least one pair of extensible ear panels extending laterally outward from the chassis in the front or back region. Each of the ear panels has an outermost edge line. In one aspect of the present invention, at least one of the outermost edge lines has a nonuniform lateral distance from the longitudinal center line in the uncontracted state of the garment. The ear panels are joined to the chassis along the corresponding edge lines to form two leg openings and a waist opening. In another aspect of the present invention, each of the ear panels is joined to the chassis along the corresponding edge lines to form a seaming line, thereby forming two leg openings and a waist opening. At least one of the seaming lines has a nonuniform lateral distance from the longitudinal center line in the uncontracted state of the garment.
