Abstract
To provide a rod-shaped cosmetic material feeding container that can sufficiently protect a rod-shaped cosmetic material from impact acting in an axial direction. The rod-shaped cosmetic material feeding container includes a female thread part with a female thread. The female thread is screwed with a male thread of a movable body. One elastic body absorbs impact acting on the female thread part in an axial direction due to, for example, a drop. The other elastic body absorbs impact due to restoring force generated when the elastic body restores. Thus, a rod-shaped cosmetic material supported by the movable body threadably mounted on the female thread part can be sufficiently protected.
Claims4
A rod-shaped cosmetic material feeding container, comprising:
- a tubular-shaped container with a front container part and a rear container part, the front container part being mounted rotatable with respect to the rear container part around an axis line and immovable in an axial direction;
- a movable body with a male thread at an outer peripheral part, the movable body being unrotatable around the axis line and movable in the axial direction with respect to the front container part, the movable body supporting a rod-shaped cosmetic material at a distal end;
- a female thread part with a female thread at an inner peripheral part, the female thread part being unrotatable with respect to the rear container part around the axis line, the female thread being screwed with the male thread;
- a first elastic body that does not surround the female thread part and is configured to reduce rearward movement of the female thread part in the axial direction;
- and
- a second elastic body that surrounds the female thread part and is configured to reduce frontward movement of the female thread part in the axial direction,
- wherein the male thread and the female thread constitute a thread engagement part, the thread engagement part acts by relative rotation of the front container part and the rear container part, the relative rotation advancing and retreating the movable body causes the rod-shaped cosmetic material to appear and disappear from an opening at a distal end of a container,
- the female thread part is movable in the axial direction.
