DISPOSABLE WEARING ARTICLE

WIPO Patent Application WO/2013/005423

A1

Provided is a disposable wearing article adapted to keep the peripheries of the respective leg-openings in close contact with the wearer's body with a good fit to prevent the absorbent core from being displaced and to prevent bodily fluids from leaking out sideways. Side flaps (61) of an absorbent chassis (12) are provided with a plurality of leg elastics (62) extending in a longitudinal direction (Y). Crossover regions (70) of the respective side flaps (61) are formed with fixed sub-regions (75) secured to an elasticized waist panel (11) and free sub-regions (76) lying outboard of the fixed sub-regions (75) in a transverse direction (X) and not secured to the elasticized waist panel (11). Each of spacing dimensions (R1, R2) in the transverse direction (X) between the adjacent leg elastics (62) is in a range of about 3.0 to about 10.0mm, a spacing dimension (R2) in the transverse direction between each of the opposite side edges (45c) of the absorbent core (45) and the innermost one of the leg elastics (62) is in a range of about 3.0 to about 10.0mm. Spaced regions (69, 71) in the transverse direction (X) between the adjacent leg elastics (62) arranged in the side flaps (61) are formed with transverse wrinkles (68) at a rate of 9 to 20 wrinkles/50mm.
