Disposable Pull-On Garment
Patent #: 6,726,669
Inventor(s): Takaaki Shimada and Kenji Nakamura
Company: Uni-Charm Corporation
A disposable pull-on garment was issued a patent. The garment features a waist-encirclable direction and a longitudinal direction orthogonal to the waist-encirclable direction. Also included in the garment is a liquid-pervious topsheet, a liquid-impervious backsheet and a liquid-absorbent core between the two. The article has front and rear waist-encirclable regions and a crotch region extending between the front and rear waist-encirclable regions. Respective longitudinal side edges of the front and rear waist encirclable regions are joined together in a longitudinal direction to define a waist-encirclable opening and a pair of leg-encirclable openings. Waist-encirclable elastic members are attached to respective edge zones of the waist-encirclable opening in the front and rear waist-encirclable regions. Plural lines of auxiliary elastic members extend in the waist-encirclable direction and are arranged to be spaced at distances from each other in a longitudinal direction in a region defined between the waist-encirclable elastic members and the leg-encirclable openings in at least one of the front and rear waist-encirclable regions. At least one of the front and rear waist-encirclable regions has first elasticized zones and a second elasticized zone, wherein the second elasticized zone traverses a portion of the core in that region and extends in the waist-encirclable direction between opposite longitudinal side edges of a portion of the core. First elasticized zones extend in the waist-encirclable direction outward from the longitudinal side edges of a portion of the core, respectively, to the adjacent longitudinal side edge of the associated waist-encirclable region. Auxiliary elastic members include plural lines of first and second auxiliary elastic members. The first auxiliary elastic members are positioned in the first elasticized zones and second auxiliary elastic members are non-continuous with the first auxiliary elastic members and are positioned in the second elasticized zone. The tensile strength of the first elasticized zone is greater than that of the second elasticized zone.
