Abstract:
1. A disposable absorbent wearing article comprising: a front waist region, a rear waist region and a crotch region; a longitudinal center line that extends through and bisects the front and rear waist regions and said crotch region and a transverse center line that extends between opposed sides of the crotch region; an elasticized waist panel defining said front and rear waist regions, said elasticized waist panel consisting of a front waist panel and a rear waist panel and respective opposite side edges of said front and rear waist panels are configured to be annularly joined together to form a waist-opening and a pair of leg-openings; and an absorbent chassis defining respective parts of said front and rear waist regions and said crotch region and joined to a front part and a rear part of said elasticized waist panel, said absorbent chassis includes an absorbent core; said absorbent core extends from said front waist region to said rear waist region via said crotch region and is formed in a region lying between said transverse center line and said front waist region with a pair of deformation guides symmetrically formed about said longitudinal center line; and at least opposite lateral zones of said absorbent core are adapted to be deformed toward the wearer's crotch region by intermediary of said deformation guides under elastic contraction of at least a part of said elasticized waist panel lying in said front waist region, wherein of said front and rear waist panels, at least said front waist panel has a pair of first elasticized regions opposed to and spaced from each other in said transverse direction and a non-elasticized region lying between said pair of elasticized regions, said first elastic regions lying adjacent said deformation guides; a front end region of said absorbent chassis lies at least in said non-elasticized region; said deformation guides are located within longitudinal edges of said absorbent core, wherein each of said pair of deformation guides has two ends, and wherein both ends of each deformation guide are spaced apart from said longitudinal edges of said absorbent core and from a front end of said absorbent core; said deformation guides are located exclusively in a region lying between said transverse center line and said front waist region and wherein said deformation guides are arranged so that a distance between the deformation guides is gradually reduced as the deformation guides extend from a vicinity of said front waist region toward said transverse center line; and said opposite lateral zones of said absorbent core are arranged so that a distance between said opposite lateral zones is gradually reduced as said opposite lateral zones extend from a vicinity of the front waist region toward said transverse center line.
