A cosmetic dispenser with an inner body, an outer body, and an elevator cup has a rotary extension and retraction mechanism, a first annular bearing surface retained relative to the inner or outer body and an annular wall retained relative to the other of the outer or inner body. The annular wall can be a skirt of the outer body and can be crenelated into arcuate merlons and crenels. The merlons establish an effective circumference that overlaps with the circumference of the first annular bearing surface to provide frictional resistance to a rotation of the inner body relative to the outer body. The merlons can surround the first annular bearing surface and establish a circumference smaller than the circumference of the first annular bearing surface. The annular bearing surface can be a lateral bearing surface, and a second annular bearing surface can form a longitudinal bearing surface. |
