A disposable diaper having front and rear waist regions that comprise an upper elasticized region extending in a vicinity of a waist-opening periphery, lower elasticized regions, intermediate elasticized region extending between the upper elasticized region and the lower elasticized regions and outside longitudinally opposite ends of a liquid-absorbent structure. At least in the front waist region of the front and rear waist regions, there is a non-elasticized region opposed to a central zone of a liquid-absorbent core wherein a tensile stress of the intermediate elasticized region is lower than a tensile stress of the upper elasticized region.

Disposable pants-type diaper

The present invention provides a disposable diaper which prevents body waste from leaking sideways without sacrificing a bodily fluid absorbing capacity of a liquid-absorbent structure and to assure a high retention for urine and discharged feces. The waist elastic members includes first and second waist elastic members wherein elastic members extend in the transverse direction across opposite lateral regions so as not to present in central zones of front and rear waist regions. The second waist elastic members in the front waist region extend from transverse opposite side edges of the front waist region in the transverse direction beyond transverse opposite side edges of a liquid-absorbent core while the second elastic members in the rear waist region extend from transverse opposite side edges in the transverse direction and terminate short of the side edges of the core.

Disposable diaper

Here is disclosed a disposable pull-on wearing article improved so that a body fluid absorbent core may be curved about a crotch region toward front and rear waist regions without forming thick creases creating a feeling of discomfort against a wearer, and wherein a concavity bulging downward may be quickly formed in the crotch region as the core is curved. The article includes a body fluid absorbent core which includes a first core lying on a transverse middle of a crotch region and a pair of second cores lying on both sides of the first core. Front and rear end portions of the respective second cores are spaced apart from the first core by slit-like gaps and intermediate portions extending between the front and rear end portions are contiguous to the first core. Outer side edges of the respective second cores are formed with laid down V-shape cutouts.
