Abstract
Abstract An elongated sanitary napkin having a longitudinal central area suitable for positioning in a user's crotch area is provided. The sanitary napkin has an upper body contacting side and a lower garment contacting side. The napkin includes an elongated absorbent core delimited by a pair of longitudinal edges and a pair of transverse edges. The absorbent core is covered on at least its upper surface with a body fluid pervious facing and on its bottom surface with a body fluid impervious facing. The sanitary napkin is characterized by the inclusion in its upper body contacting side of two series of discrete indentations. One series of indentations is positioned adjacent to one of the longitudinal edges of the absorbent core and the other series of indentations is positioned adjacent to the opposite longitudinal edge of the absorbent core.
