Abstract
A sanitary napkin including a central absorbent pad, the central absorbent pad having a liquid pervious cover layer, a liquid impervious barrier layer and an absorbent core between the cover layer and barrier layer. The central absorbent pad includes a pair of flaps adapted to fold over a crotch portion of an undergarment in use. The central absorbent pad further includes two preferential bending axes, each axis being inward from and adjacent to a respective longitudinal side edge and extending obliquely with respect to the longitudinal centerline, the axes converging towards the longitudinal centerline in the first distal end of the central absorbent pad. The preferential bending axes are adapted to enable the sanitary napkin to be folded from an initial substantially hourglass shape to a tapered shape.
