Abstract
A sanitary napkin is provided which minimizes the probability of side staining or side leakage by using embossed channels which are located adjacent to the longitudinal edges of the napkin. These embossed channels are activated during use by the thighs, allowing the sides of the napkin to fold upwards during use, thus forming an occlusive container.
