Abstract
An absorbent article includes a moisture barrier formed of a formable, liquid impermeable material. The moisture barrier defines a basin having a width dimension, a length dimension greater than the width dimension, and a volume. The basin includes a floor having corrugations formed therein parallel to the width dimension. The absorbent article also includes an absorbent assembly disposed within the basin and a liner formed of a liquid permeable material bonded to the moisture barrier and sandwiching the absorbent assembly therebetween. The corrugations permit the absorbent article to bend inwardly, for example to conform to the shape of the wearer, without bunching the moisture barrier along the portions facing the wearer and without substantially stretching or deforming the floor of the moisture barrier.
