1. An absorbent article having a crotch region and a body side, the absorbent article comprising:
- a) a liquid impervious backsheet;
b) a liquid pervious topsheet attached to the backsheet;
c) an absorbent core positioned between the topsheet and the backsheet, the absorbent core comprising;
a central absorbent member having a width in the crotch region and including a shaping line, and an outer absorbent member having a width in the crotch region greater than the width of the central absorbent member in the crotch region, the absorbent core further comprising at least two crease lines in the outer absorbent member or along the boundary between the central absorbent member and the outer absorbent member, wherein the at least two crease lines and the shaping line each define a sudden change in material properties of the absorbent core wherein, during lateral compression in the crotch region, the outer absorbent member is adapted to deflect in a direction away from the body side along at least one of the crease lines and the central absorbent member is adapted to deflect in a direction toward the body side along the shaping line.

Abstract
An absorbent article with improved body fit wherein a combination of downward-deflecting crease lines and an upward-deflecting shaping line are used in outer and central absorbent members, respectively, to achieve a form-fitting geometry in the crotch region while also enhancing control over fluid flow in the article. Embodiments with wicking barriers between the outer and central absorbent members are especially useful in achieving leakage reduction.
