Abstract:
A compound sanitary napkin having a longitudinal center line along a longitudinal direction and a transverse center line along a transverse direction the sanitary napkin comprising:(a) a primary absorbent member having a longitudinal length, a transverse width, a thickness, a pair of longitudinal sides and a pair of transverse ends, and comprising a primary absorbent element and a fluid pervious cover superimposed on the primary absorbent element; (b) a base member having a longitudinal length, a transverse width, at thickness, a pair of longitudinal sides and a pair of transverse ends, and comprising a fluid pervious body-facing sheet and fluid impervious garment-facing sheet joined to the fluid pervious body-facing sheet, and the primary absorbent member joined to the base member at least at a part of the longitudinal direction of the primary absorbent member; (c) flaps extending laterally outwardly from the longitudinal sides of the base member, each of the flaps having a proximal edge joined with the longitudinal sides of base member and a distal edge spaced laterally outwardly from the proximal edge, the flaps covering a portion of the leg openings of the wearer's undergarment, the flaps are biased toward one transverse end of the base member, and additional flaps are provided along the longitudinal sides of the base member adjacent to the other transverse end of the base member; (d) at least one zone of extensibility comprising a least a portion of the flaps, wherein at least a portion of the zone of extensibility is spaced longitudinally away from the flap transverse centerline, wherein (e) the entire length of the proximal edge of the flaps is not less than 20% of the length of the primary absorbent member; and (f) at least the zone of extensibility is extensible to be capable of a stress given to the flap when the compound sanitary napkin is worn so that the flaps are relatively free from shifting when at least a portion of the primary absorbent members shifts away from the flap.
