<p>A lipstick or cosmetic dispenser 20 having a tubular cam sleeve 30 and an innerbody 50 fitted inside the cam sleeve 30, and internal helical tracks 40, 42 supporting an elevator cup 100. The cam sleeve 30 has a lower cam skirt with a plurality of ribs 84 provided on its inner wall. The innerbody 50 has a beveled shoulder 96 around a lower outer wall thereof. The cam skirt ribs 84 bear against the beveled shoulder 96 to create frictional drag between the innerbody 50 and the cam sleeve 30, and to cause the cam sleeve 30 to be urged upwardly. The ribs 84 on the inner wall of the cam skirt extend at an angle relative to a centerline of the dispenser 20, and preferably are angled the same direction as the internal helical tracks 40, 42 of the cam sleeve 30. There are from three to seven ribs 84 located equidistantly from each other around the inner wall of the cam skirt. The ribs 84 may be connected with each other by webs or separated by slots. <IMAGE>A lipstick or cosmetic dispenser 20 having a tubular cam sleeve 30 and an innerbody 50 fitted inside the cam sleeve 30, and internal helical tracks 40, 42 supporting an elevator cup 100.
