Disposable panttype diaper having improved protection against red marking and method for making the same

摘要

A disposable pull-on garment (120) having a longitudinal centre line, a front region (26), a back region (28) and a crotch region (30) between the front region (26) and the back region (28) is disclosed. The disposable pull-on garment (120) includes a chassis (41) provided in the front, back and crotch regions. The chassis (41) has edge lines (222) in the front and back regions and includes a liquid pervious top sheet (24), a liquid impervious back sheet (22) associated with the top sheet (24), and an absorbent core disposed between the top sheet and the back sheet. The disposable pull-on garment (120) further includes at least one pair of extensible ear panels (45) extending laterally outward from the chassis in the front or back region (26, 28). Each of the ear panels (45) has an outermost edge line (242). Each of the ear panels (45) are joined to the chassis along the corresponding edge lines (242) to form a seam (232), thereby forming two leg openings and a waist opening. At least one of the ear panels (45) has, along the seam, a substantially bonded portion starting from the waist opening and an unbonded portion starting from the leg opening. The ratio in length of the unbonded portion to the substantially bonded portion is between about 4:96 and about 20:80. The present disclosure is also directed to a method for making such a disposable pull-on garment.
