  • Patent number: 5899621
    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.

  • Patent number: 5813421
    Abstract: A lipstick swivel mechanism includes a cup having a cup body for holding a lipstick bullet; a nosepiece for containing the cup and guiding the movement of the cup; a spiral rotatably connected to the nosepiece, having helical guiding grooves formed on the inner surface thereof; and a screw received within the spiral and detachably connected to the cup. The screw has double helical protrusions, formed on the outer surface of the screw. The double helical protrusions are received in and guided by the helical guiding grooves inside the spiral so as to make the screw and the cup move upward or downward when the spiral is rotated. The problem of idling rotation of screw may be solved.
