Abstract
A sanitary napkin having flaps extending laterally from each of the longitudinal edges of its central absorbent element is provided with at least one fluid retarding channel disposed transversely across the absorbent element for inhibiting the transmission of body fluid from a central portion of the absorbent element to at least one transverse end. The preferred construction employs the use of two spaced apart compressed portions of the absorbent element to define a central absorbent portion and delay the transmission of body fluid from the central portion into the transverse end portions of the absorbent element, thereby minimizing the incidence of leakage from the ends of the napkin.
