Claims16
A disposable wearing article, comprising:
- an absorber having
- a lengthwise direction configured to extend to a front of a body of a wearer and a back of the body of the wearer,
- a widthwise direction perpendicular to the lengthwise direction,
- an inner direction configured to face the wearer,
- an outer direction opposite to the inner direction,
- a crotch region configured to be in contact with a crotch portion of the wearer,
- a front region arranged anterior to the crotch region in the lengthwise direction, and
- a back region arranged posterior to the crotch region in the lengthwise direction and configured to be in contact with a hip portion of the wearer;
- a pair of curving members provided in the crotch region and extending along the lengthwise direction to enable the absorber to curve in a convex shape in the inner direction;
- and
- a pair of lifting units provided outside the curving members in the widthwise direction and extending along the lengthwise direction to enable the absorber to be lifted up in the inner direction in the back region,
- wherein
- back ends of the curving members are positioned anterior to back ends of the lifting units in the lengthwise direction, and
- the curving members and the lifting units are arranged to overlap the absorber.
