Rod-shaped cosmetic material feeding container
The rod-shaped cosmetic material feeding container includes a female screw portion provided with a female screw for screw engagement with a male screw of a rod-shaped cosmetic material support, a coil spring that restrains the female screw portion from moving forward in an axial direction, and a resin spring that restrains the female screw portion from moving rearward in the axial direction. An impact in the axial direction that acts on the female screw portion is absorbed by one spring, and an impact due to a restoring force at the time of restoration of one spring is absorbed by the other spring, whereby a rod-shaped cosmetic material supported by the rod-shaped cosmetic material support put in screw engagement with the female screw portion is sufficiently protected.
1. A rod-shaped cosmetic material feeding container comprising:
a tubular container provided with a front portion of the container and a rear portion of the container, the rear portion of the container mounted to the front portion of the container in such a manner as to be rotatable about an axis and immovable in an axial direction;
a movable body non-rotatable about the axis and movable in the axial direction in relation to the front portion of the container, the movable body supporting a rod-shaped cosmetic material at a leading end thereof and provided with a male screw at an outer peripheral portion thereof;
a female screw portion non-rotatable about the axis in relation to the rear portion of the container and movable in the axial direction, the female screw portion being provided at an inner peripheral portion thereof with a female screw for screw engagement with the male screw;
a first elastic body that accumulates an elastic force between the front portion of the container and the female screw portion and restrains the female screw portion from moving forward in the axial direction; and
a second elastic body that restrains the female screw portion from moving rearward in the axial direction, wherein
relative rotation of the front portion of the container and the rear portion of the container causes a screw part composed of the male screw and the female screw to function to advance or retract the movable body, whereby the rod-shaped cosmetic material is protruded or retracted through an opening at a leading end of the container,
the first elastic body and the second elastic body are disposed along the axial direction in such a manner as to overlap with each other in a radial direction.
2. The rod-shaped cosmetic material feeding container according to claim 1 , further comprising:
an anti-rotation portion provided in a row with a rear end portion of the second elastic body, wherein
the anti-rotation portion is engaged with the rear portion of the container in such a manner as to be non-rotatable about the axis by an axial-directionally rearward elastic urging of the first elastic body.
3. The rod-shaped cosmetic material feeding container according to claim 2 , further comprising:
a female screw member provided with the female screw portion, the second elastic body, and the anti-rotation portion in a row in this order from a front side toward a rear side in the axial direction.
