Abstract
The present invention relates to a sanitary napkin consisting of an absorbent core (1) surrounded by a casing built up of two surface layers which are joined together around the absorbent core and of which surface layers the one facing the wearer's body is liquid permeable whereas the other one (2) is liquid impermeable. According to the invention, elastic means (5,6) are applied to the liquid impermeable surface layer (2). The resiliency afforded to the sanitary napkin in this manner will urge the napkin in its applied condition to press against the outer genitals of the wearer.
