A rod-shaped cosmetic material feeding container in which a leading tube and a container main body are relatively rotated in one direction, an action of a screw part moves a rod-shaped cosmetic material supporting body to reach a movement limit, and then the leading tube and the container main body are further relatively rotated in the one direction. With movement of the rod-shaped cosmetic material supporting body stopped, while a spring portion in a rotation stopper tube shrinks, the screw part screws forward to release screwing of the screw part. Additionally, the movement of the rod-shaped cosmetic material supporting body is stopped and therefore the rod-shaped cosmetic material supporting body does not move back and forth in an axial direction. Accordingly, a rod-shaped cosmetic material does not move back and forth in the axial direction as well, thereby ensuring minimizing an impact to the rod-shaped cosmetic material. |

1. A rod-shaped cosmetic material feeding container comprising:
a tubular container that has a front container part and a rear container part; a movable body engaged with the front container part in a rotation direction around an axis line, the movable body being movable in an axial direction, the movable body supporting a rod-shaped cosmetic material at a distal end and including a male screw at an outer peripheral portion; and a rotation stopper tube rotatable with respect to the front container part around the axis line, the rotation stopper tube being synchronously rotatable with respect to the rear container part around the axis line, the rotation stopper tube including a female screw at an inner peripheral portion, the female screw being screwed with the male screw, wherein: a relative rotation of the front container part and the rear container part works a screw part constituted of the male screw and the female screw to advance and retreat the movable body, the relative rotation causes the rod-shaped cosmetic material to appear and disappear from an opening at a distal end of the container, the rotation stopper tube includes a spring portion expandable and contractible in the axial direction, and if the front container part and the rear container part are relatively rotated in one direction, the movable body moves and reaches a movement limit, and the front container part and the rear container part are further relatively rotated in the one direction, the screw part screws forward while the spring portion shrinks with the movement of the movable body stopped to release the screwing of the screw part. |
