Abstract:
An absorbent article having a pair of longitudinal edges, front and rear transverse edges, a front end region, a rear end region, and a central region disposed between the front and rear end regions. The absorbent article has a liquid pervious topsheet, a liquid impervious backsheet, an absorbent core disposed between the topsheet and the backsheet, and a pair of outwardly convex longitudinal central channels formed at least in the central region. The traversal distance of the pair of outwardly convex longitudinal central channels decreases towards both ends of the channels to define a central closed area. The absorbent article has a rear channel defining a rear closed area in the rear end region. The absorbent core is profiled within the central closed area so that the central region has a caliper that is greater than the caliper of the outside of the central closed area.
