Claim:
A disposable pull-on wearing article having a longitudinal axis and a transverse axis, said article comprising: a front waist region; a rear waist region; a crotch region; an outer cover; a body fluid absorbent panel being bonded at a transversely middle zone thereof and at longitudinally opposite ends to said outer cover and extending over said crotch region further into said front and rear waist regions, said body fluid absorbent panel having a longitudinal direction extending toward said front and rear waist regions and a transverse direction crossing said longitudinal direction, said body fluid absorbent panel comprising a body fluid absorbent core having an inner surface facing a wearer's skin and an outer surface facing away from said wearer's skin and a liquid-pervious sheet covering at least said inner surface of said inner surface and facing said wearer's skin; said core traversing said crotch region and extending into said front waist region and into said rear waist region, and comprising a central portion extending longitudinally from said front waist region through said crotch region into said rear waist region, said core also comprising two lateral portions, each lying on opposite lateral sides of said central portion; said lateral portions each having a front end region, a rear end region and an intermediate region between front and rear end regions as viewed in said longitudinal direction; said front and rear end regions being spaced apart from said central portion by front and rear pairs of slit-like gaps formed in said core between said central portion and said lateral portions and extending in an arc from lateral edges of said core toward said longitudinal axis and toward said transverse axis, and said intermediate region of each lateral portion being contiguous to and continuous with said central portion; wherein an outer side edge of said intermediate region of each lateral portion defines a plurality of V shaped cutouts whose vertices point toward said longitudinal axis, and whose sides diverge from one another as they extend away from said longitudinal axis; and said body fluid absorbent panel being provided in a vicinity of said outer side edges with elastic members extending in a stretched state in said longitudinal direction.
