Definitions

  • FIG. 1 also shows that the main body portion of the sanitary napkin 20 has a periphery 30 which is defined by the outer edges of the main body portion of the sanitary napkin 20 in which the longitudinal edges (or “side edges") are designated 31 and the end edges (or “ends”) are designated 32.
  • the sanitary napkin 20 is symmetrical with respect to both the longitudinal and transverse centerlines.
  • Sanitary napkin 20 preferably includes side flaps or "wings" 34 that are folded around the crotch portion of the wearer's panties.
  • the side flaps 34 can serve a number of purposes, including, but not limited to, protecting the wearer's panties from soiling and keeping the sanitary napkin secured to the wearer's panties.
  • the backsheet 23 is a polyethylene film having a thickness of from about 0.012 mm (0.5 mil) to about 0.051 mm (2.0 mils).
  • the backsheet 23 may be embossed and/or matte finished to provide a more clothlike appearance. Further, the backsheet 23 may permit vapors to escape from the absorbent core 25 (i.e., breathable) while still preventing exudates from passing through the backsheet 23.
  • a suitable backsheet material is obtained as product No. 18-1401 from the Clopay Corporation of Cincinnati, Ohio.
  • a suitable breathable backsheet material is a laminate of an apertured film such as that described in U.S.
  • the garment surface 20B of the sanitary napkin 20 may include, and preferably does include, fasteners for attaching the sanitary napkin to the wearer's undergarment.
  • FIG. 2 shows the central pad fastener 82 which is adapted to secure the main body portion of the sanitary napkin to the crotch region of an undergarment. Any types of fasteners known in the art, such as adhesive fasteners and mechanical fasteners can be used. Fasteners comprising adhesives have been found to work well for this pu ⁇ ose, with pressure-sensitive adhesives being preferred.
  • the central pad fastener 82 comprises a pair of spaced apart longitudinally-oriented strips or zones of adhesive that are centered about the longitudinal centerline L.
