Abstract
The invention provides an absorbent structure, such as a disposable diaper or a training panty, including a first outer layer in the form of a moisture-impervious backing sheet, a second outer layer in the form of a liquid barrier positioned in superposed relationship with respect to the backing sheet and an absorbent batt sandwiched between the first and second outer layers. The liquid barrier has a single opening situated so as to contact the perineal region of the wearer.
