Title: Absorbent article having absorbent core including regions of lower thickness

Abstract: An absorbent article 10 has front 12, crotch 14 and rear 16 portions. The article has an absorbent core 18 of unitary construction and of uniform density, which is defined by a pair of opposing longitudinal edges 20;22 and a pair of opposing transverse edges 24;26. The absorbent core 18 has at least a first 28 and a second 30 region, the average thickness of the absorbent core 18 in these first and second regions 28, 30 being lower than the average thickness of the absorbent core 18 surrounding the first and second regions 28;30, the first and second lower thickness regions 28;30 being arranged symmetrically about the longitudinal center line A of the article such that each of the first and second lower thickness regions 28;30 extends to the respective longitudinal edge 20;22 of the absorbent core. The distance a.sub.x between the first and second lower thickness regions 28;30 in the transverse direction varying along the longitudinal direction of the article. A minimum distance a.sub.1 between the first and second lower thickness regions 28;30 in the transverse direction is located at least in the transition 32 between the crotch portion 14 and the front portion 12.
