  • Patent number: 5174440
    Abstract: A lipstick case includes a stationary tube formed with an axially extending guide slot, a rotatable tube formed with an internal spiral groove and rotatably sleeved on the stationary tube, and a lipstick base provided inside the stationary tube and receiving a lipstick therein. The lipstick base has an outward radial projection which extends into the guide slot and the spiral groove. A sound generating unit is provided on a lower end of the stationary tube and is operable so as to generate sound when the rotatable tube is rotated relative to the stationary tube in order to move the projection of the lipstick base upwardly along the guide slot and the spiral groove and thereby protrude the lipstick out of the stationary tube.
