PULL-ON DIAPER

摘要

In a pull-on diaper, a distance dimension between outer end portions of front and rear waist panels is in a range of 300 mm to 400 mm as measured on the diaper flatly developed after coupling of the front and rear waist panels in seam regions has been released. A distance dimension between the waist elastic closest to an inner end portion of the front waist panel among waist elastics extending in the front waist panel across the respective seam regions in the front waist panel and the waist elastic closest to an inner end portion of the rear waist panel among waist elastics extending in the rear waist panel across the respective seam regions is at least 55% of the distance dimension between respective outer end portions of the front and rear waist panels.

主权项

1. A pull-on diaper having a transverse direction and a longitudinal direction being orthogonal to each other and including:
a front waist panel; a rear waist panel both extending in the transverse direction; and a crotch panel extending in the longitudinal direction and coupled with the front and rear waist panels, wherein: a plurality of waist elastics extending in the transverse direction are contractibly attached under tension to the front and rear waist panels, respectively; first leg elastics are contractibly attached under tension to lateral portions of the crotch panel; lateral portions of the front waist panel are coupled with associated lateral portions of the rear waist panel in respective seam regions so that respective outer end portions of the front and rear waist panels form a waist-opening periphery; respective inner end portions of the front and rear waist panels cooperate with the lateral portions of the crotch panel to define a pair of leg-openings' peripheries; a distance dimension between the outer end portions of the front and rear waist panels is in a range of 300 mm to 400 mm as measured on the diaper flatly developed after coupling of the front and rear waist panels in the seam regions has been released; and a distance dimension between the waist elastic closest to the inner end portion of the front waist panel among the waist elastics extending in the front waist panel across the respective seam regions in the front waist panel and the waist elastic closest to the inner end portion of the rear waist panel among the waist elastics extending in the rear waist panel across the respective seam regions is at least 55% of the distance dimension between the respective outer end portions of the front and rear waist panels.
