  • Patent number: 5746530
    Abstract: A stick cosmetic container is constructed so that a medium holder is moved into or out of a casing by a driving mechanism. The medium holder has first and second holding members which can be moved relative to each other. The two holding members may be moved in one axial direction relative to each other so that the stick cosmetic is forced forward from one of the holding members. A stopper is provided in association with the two holding members so as to directly restrict the beginning and/or the continuation of the relative movement of the two holding members in the one axial direction.
