Abstract
A sanitary napkin having flaps extending laterally from each of the longitudinal edges of its central absorbent element is provided with fluid retarding means disposed transversely across the absorbent element for inhibiting the transmission of body fluid from a central portion of the absorbent element to the transverse ends. The preferred construction employs the use of two spaced apart compressed channels in the absorbent element. The napkin may include fluid barrier seals between the central absorbent element and the side flaps to prevent the transmission of fluids into the side flap area. The napkin also includes fluid repellant means around the periphery of the transverse ends to aid in preventing end failure.
