Patent ID: 8518009

Claim:
A disposable diaper having, relative to a wearer, a longitudinal direction, a transverse direction, a side facing said wearer's skin, a side facing away from said wearer's skin, said disposable diaper comprising: an annular elasticized waist panel defining a waist opening, a front waist region and a rear waist region; an absorbent chassis joined to said waist panel and extending into said front and rear waist regions, said absorbent chassis defining a crotch region extending between said front and rear waist regions and including an absorbent core and front and rear end flaps extending from front and rear ends of said absorbent core in said longitudinal direction; at least said front waist region of said front and rear waist regions including elasticized regions extending at least in said transverse direction; said elasticized regions including a first elasticized region, a second elasticized region and a pair of third elasticized regions, said first elasticized region located between a periphery of said waist-opening and said front end flap of said absorbent chassis, said second elasticized region located adjacent said first elasticized region and extending across said front end flap of said absorbent chassis, said pair of third elasticized regions located adjacent said second elasticized region, each of said third elasticized regions extending from opposite side edges of said front waist region to opposite side edges of said absorbent chassis, said third elasticized regions being spaced from and opposed to each other in said transverse direction on both sides of a non-elasticized region located in a transverse middle portion of said front waist region, wherein said rear waist region includes a pair of fourth elasticized regions extending in the longitudinal direction on opposite sides of a rear non-elasticized region located in a transverse middle portion of the rear waist panel, said fourth elasticized regions having a tensile stress in said transverse direction that is lower than a tensile stress in said transverse direction of any of said first, second and third elasticized regions.
