Abstract

A rod-shaped cosmetic material feeding container includes a tubular-shaped container with a front container part and a rear container part, a movable body with a male thread at an outer peripheral part that supports a rod-shaped cosmetic material at a distal end and a female thread part with a female thread at an inner peripheral part that is engaged with the male thread. A first elastic body is configured to accumulate resilient force against the rear container part and reduce rearward movement of the female thread part in the axial direction. A second elastic body is configured to accumulate resilient force against the front container part and reduce frontward movement of the female thread part in the axial direction. The first elastic body is a resin spring integral with the female thread part.

First claim

What is claimed is:

1. 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 configured to accumulate resilient force against the rear container part and reduce rearward movement of the female thread part in the axial direction; and
a second elastic body configured to accumulate resilient force against the front container part and 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, and the first elastic body is a resin spring integral with the female thread part.

2. The rod-shaped cosmetic material feeding container according to claim 1 , wherein the second elastic body is a coil spring.
