Open-type Disposable Wearing Article Having Bifurcated Stretchable Zones



Published October 17, 2006
Patented is an open-type disposable clothing article with an elastically stretchable front waist region, an elastically stretchable rear waist region and an elastically stretchable crotch region extending between the front waist region and the rear waist region. The front and rear waist regions are connectable in opposite lateral zones. A first stretchable zone is bifurcated at a transverse middle of the crotch region so as to extend in two laterally separated portions to the opposite lateral zones of the front waist region. The first stretchable zone has a substantially uniform tensile stress, a second stretchable zone bifurcated at the transverse middle of the crotch region so as to extend in two laterally separated portions to the opposite lateral zones of the rear waist region. The second stretchable zone has a substantially uniform tensile stress. Third stretchable zones defined by zones other than the first and second stretchable zones extend between the two laterally separated portions of each of the first stretchable zone and the second stretchable zone and along lateral side portions of at least the crotch region. A tensile stress of the first and second stretchable zones is higher than a tensile stress of third stretchable zones. First engageable means are included for connecting the front and rear waist regions. First engageable means are provided in a second stretchable zone in the opposite lateral zones of the rear waist region. First receiving means releasably engage with the first engageable means. First receiving means are provided in the first stretchable zone in the opposite lateral zones and second engageable means for connecting the front and rear waist regions are provided in the third stretchable zones lying in opposite lateral zones of the rear waist region. Second receiving means for releasably engaging the second engageable means are provided in the third stretchable zones lying in the opposite lateral zones of the front waist region.
