- 7. An applicator as in claim 2 wherein said applicator surface is a nonwoven fabric.
- 8. An applicator as in claim 7 wherein said nonwoven fabric is an extruded film having a plurality of apertures.
- 9. An applicator as in claim 7 wherein said nonwoven fabric is a plurality of random fibers in a random array.
- 10. An applicator as in claim 2 wherein there is at least one support beneath said applicator surface.
- 11. An applicator as in claim 10 wherein said applicator has a major axis and a minor axis, said support extending across said major axis.
- 12. An applicator as in claim 11 wherein said support forms said applicator surface into a compound curve.
- 13. An applicator as in claim 2 wherein said applicator surface is one of a polyene and a polyester.
- 14. An applicator as in claim 2 wherein said fabric has apertures of about 75 microns to about 350 microns.
- 15. An applicator as in claim 14 wherein said fabric has apertures of about 100 microns to about 250 microns.
- 16. An applicator for a semisolid substance comprising a barrel closed at one end by an elevator adapted to move axially within said barrel, and closed at another end by an applicator surface, said applicator surface comprised of an extruded film having about 20 to about 50 strands per 2.54 cm and nominal mesh apertures of about 100 microns to about 500 microns and a thickness of about 0.033 cm to about 0.30 cm, said extruded film insert molded to a frame insert said strands having a modified top surface.
- 17. An applicator as in claim 16 wherein said modified surface has been calendared.
- 18. An applicator as in claim 17 wherein said extruded film has nominal mesh apertures of about 125 to about 225 microns.
- 19. An applicator as in claim 17 wherein said applicator surface has mesh openings each having an open area of about 2.5×10−3 mm2 to about 1 mm2.
- 20. An applicator as in claim 17 wherein said extruded film has about 30 to 40 strands per 2.54 cm.
- 21. An applicator as in claim 17 wherein said extruded film has a thickness of about 0.05 cm to about 0.15 cm.
- 22. A method of forming an applicator surface for the application of flowable substances to a body surface comprising:providing at least one of a woven and a nonwoven fabric; modifying an upper surface of said fabric; inserting said fabric into a first section of an injection mold, the fabric extending substantially across a cavity of said first mold section; inserting a mating second mold section into said first mold section; and injecting a hot thermoplastic plastic into at least one of said first and second mold sections to simultaneously form a support frame for said fabric and to bond said fabric to said support frame.
- 23. A method as in claim 22 wherein said first mold section and said second mold section hold said fabric in a compound curve shape.
- 24. A method as in claim 23 wherein said first mold section and said second mold section form an angle of about 5° to about 50° to a horizontal plane through said support frame on the upper edge of said support frame whereby said fabric is further formed into said compound curve shape.
- 25. A method as in claim 22 wherein said fabric is an extruded film having from about 20 to 50 strands per 2.54 cm and nominal mesh aperture of about 100 microns to about 500 microns.
- 26. A method as in claim 25 wherein said fabric has about 30 to 40 strands per 2.54 cm and nominal mesh apertures of about 125 microns to about 250 microns.
- 27. A method as in claim 22 wherein said upper surface is modified by calendaring.
