US Patent 7942859 Disposable wearing article

A wearing article includes a flexible chassis and a semi-rigid absorbent panel laid on inner surface of the chassis. A liner defining an innermost layer of the chassis is bonded to the absorbent panel in a fixed zone defined in a crotch region. A passage is formed through the liner at a position put aside from the fixed zone toward a rear waist region to guide feces through this passage. A first elastic member extends along a peripheral edge of the passage so as to be stretchable and contractible. A second elastic member and a third elastic member are paired and laid outside opposite side edges of the passage so as to be stretchable and contractible in a longitudinal direction in a vicinity of the passage.
