Abstract

A disposable wearing article includes a central curving unit that allows the absorber to curve in the inner direction in a convex shape is formed in the center of the absorber, a pair of first curving units along the front-back direction that allow the absorber to curve in the outer direction in a convex shape is formed outboard of the central curving unit of the absorber, a pair of second curving units along the front-back direction that allow the absorber to curve in the inner direction in a convex shape is formed outboard of the first curving unit of the absorber, and a front end of the central curving unit is positioned posteriorly of a front end of a second curving unit.

Dependent claims

A disposable wearing article, comprising:

an absorber having a front-back direction, a widthwise direction perpendicular to the front-back direction, an inner direction for facing a wearer, and an outer direction opposite the inner direction,
wherein
the absorber has a central portion formed in a center of the absorber in the widthwise direction, a pair of side end portions including side ends of the absorber in the widthwise direction, and a pair of intermediate portions positioned between the central portion and the side end portions, in a crotch region that is adapted to be in contact with a crotch of the wearer,
a central curving unit that allows the absorber to curve in the inner direction in a convex shape is formed in the center of the absorber,
a pair of first curving units along the front-back direction that allow the absorber to curve in the outer direction in a convex shape is formed outboard of the central curving unit of the absorber in the widthwise direction,
a pair of second curving units along the front-back direction that allow the absorber to curve in the inner direction in a convex shape is formed outboard of the first curving unit of the absorber in the widthwise direction,
a top surface of the absorber that takes a convex shape in the inner direction due to the central curving unit is adapted to be in contact with the crotch of the wearer,
a front end of the central curving unit is positioned posteriorly of a front end of at least one of the second curving units,
the absorber includes:
a first layer positioned at a non-skin contact surface side;
and
a second layer overlapping the first layer and being positioned at a skin contact surface side,
the absorber in the central portion is formed only by the second layer,
the absorber positioned between the central curving unit and the first curving units is formed by the first layer and the second layer, and
the absorber positioned between the first curving units and the second curving units is formed only by the second layer.
