Abstract:
1. A disposable absorbent wearing article defining a longitudinal center line in a longitudinal direction and a transverse center line in a transverse direction, said disposable absorbent wearing article comprising; an elasticized front waist panel and an elasticized rear waist panel respectively defining a front waist region and a rear waist region; an absorbent chassis joined to and extending between said front and rear waist panels in said longitudinal direction, said absorbent chassis defining respective parts of said front and rear waist regions and defining a crotch region; said absorbent chassis including an absorbent structure having an absorbent core and a pair of side flaps extending outward in said transverse direction from opposite lateral regions of said absorbent core, each of said pair of side flaps being elastically contractible under an effect of at least one strand of an elastic element attached thereto; said front waist panel including a first elasticized region and a second elasticized region, said second elasticized region lying adjacent to said first elasticized region and defining a waist band; said rear waist panel including a third elasticized region, a fourth elasticized region and a pair of fifth elasticized regions, said third elasticized region corresponding to said first elasticized region, said fourth elasticized region corresponding to said second elasticized region, said pair of fifth elasticized regions lying adjacent to said third elasticized region on a side thereof toward said crotch region; said third elasticized region and said fourth elasticized region being elastically contractible by a plurality of strands of elastic elements extending in said transverse direction; said pair of fifth elasticized regions having inner side edges that are opposed to each other in said transverse direction, said inner side edges extending obliquely relative to said longitudinal center line, said pair of elasticized regions being elastically contractible by at least one strand of an elastic element; said pair of fifth elasticized regions having a tensile stress in said transverse direction that is less than a tensile stress of any of said first, second, third and fourth elasticized regions; and said rear waist panel having a rear panel dimension measured in said longitudinal direction that is greater than a front panel dimension of said front waist panel measured in said longitudinal direction by a fifth region dimension of said fifth elasticized region measured in said longitudinal direction.
