Abstract
The present invention relates to a compound sanitary napkin ( ) comprising a primary absorbent member ( ), a base member ( ), flaps ( ) and at least one zone of extensibility ( ). The compound sanitary napkin ( ) has a longitudinal center line along a longitudinal direction and a transverse center line along a transverse direction. The primary absorbent member ( ) has a longitudinal length (PL), a transverse width (PW), a thickness (PT), a pair of longitudinal sides ( ) and a pair of transverse ends ( ), and comprises a primary absorbent element ( ) and a fluid pervious cover ( ) superimposed on the primary absorbent element ( ). The base member ( ) has a longitudinal length, a transverse width, a thickness, a pair of longitudinal sides ( ) and a pair of transverse ends, and comprises a fluid pervious body-facing sheet ( ) and a fluid impervious garment-facing sheet ( ) joined to the fluid pervious body-facing sheet ( ), the primary absorbent member ( ) is joined to the base member ( ) at least at a part of the longitudinal direction of the primary absorbent member ( ). Flaps ( ) extend laterally outwardly from the longitudinal sides of the base member ( ). Each of the flaps ( ) has a proximal edge ( ) joined with the longitudinal sides ( ) of the base member ( ), a distal edge ( ) spaced laterally outwardly from the proximal edge ( ). The flaps ( ) cover a portion of the leg openings of the wearer's undergarment. At least one zone of extensibility ( ) comprises at 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. The entire length of the proximal edge of the flaps ( ) is not less than 20% of the length of the primary absorbent member ( ). 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 member ( ) shifts away from the flap ( ).
