Abstract:
1. An absorbent article comprising transverse and longitudinal directions, said article further having front, crotch and rear portions arranged sequentially in the longitudinal direction, said article comprising an absorbent core of unitary construction and uniform density, said absorbent core being defined by a pair of opposing longitudinal edges extending substantially in the longitudinal direction and a pair of opposing transverse edges extending substantially in the transverse direction, said absorbent core having at least a first region and a second region, the average thickness of the absorbent core in these first and second regions being lower than the average thickness of the absorbent core extending around said first and second regions, the absorbent core extending around each of the first and second thinner regions from one point above the first or second thinner region in the longitudinal direction at a longitudinal edge of the absorbent core to a second point below the first or second region in the longitudinal direction at the same longitudinal edge of the absorbent core, said first and second thinner regions being arranged symmetrically with respect to each other about the longitudinal center line of the article and extending to the respective longitudinal edges of the absorbent core, the distance between said first and second thinner regions in the transverse direction varying along the longitudinal direction of the article, and a minimum distance between said first and second thinner regions in the transverse direction is located at least in the transition between the crotch portion and the front portion of the article.
