Abstract

Patent of Invention for A DISPOSABLE SANITARY PAD
comprising at least one compression line (10) along and close to each longitudinal edge (9), so that the pressure of the user's thighs (12,10 on the product will bring about the appearance of a protuberance (14) of absorbing material (3) toward the perineal area (11). The invention aims at decreasing the course from the point of discharge to the absorbing material (3), which is the critical cause of leakage from the sides.
