    Abstract: A lipstick swivel mechanism has a brake function, by which push back of the lipstick when the lipstick is being pressed is effectively hindered. An additional protrusion and a corresponding beveled helical groove are provided on the inner body and the spiral of the dispenser. When the reaction force of applying the lipstick to the consumer's lips pushes the lipstick cup down the dispenser, this reaction force is transmitted to the protrusion and the beveled helical groove so as to increase the frictional force, which impedes the relative rotation of inner body and spiral, between them; thereby push back of the lipstick cup is obstructed. Besides, the beveled helical groove is specially designed so as to make such brake function effective across the entire travel of the lipstick cup.
