Abstract:
1. A rod-shaped cosmetic material feeding container comprising: a container front portion which is formed as a tubular shape being open in both ends; a rod-shaped cosmetic material formed by being directly filled with a cosmetic material in an inner portion of the container front portion, and closely attached to the inner portion; a piston body provided to be slidable in said inner portion of the container front portion in a closely attached state; a container rear portion which is relatively rotatable with respect to said container front portion; a moving body which is arranged in a rear side of said piston body within the container rear portion and is provided with a male thread in an outer periphery at one end and further provided with an outer peripheral rotation stop at an opposite end; and a female thread which is provided within said container rear portion and is connected by screw to said male thread; wherein said rod-shaped cosmetic material feeding container is structured such that if said container front portion and said container rear portion are relatively rotated in a feeding direction, a screwing action between said male thread and said female thread works, said moving body moves forward, and said rod-shaped cosmetic material appears from an opening portion in a leading end of said container front portion in accordance with a forward movement of said piston body, and wherein said piston body and said moving body are separated so as not to be constrained to each other; wherein said piston body is provided in a rear end surface thereof with a concave portion which is concaved toward a front side, and wherein said moving body is provided in a leading end surface thereof with a convex portion which enters into said concave portion so as to come into contact therewith; and wherein said piston body is also provided in a leading end surface thereof with a concave portion which is concaved toward a rear side and has the same shape as said concave portion which is concaved toward the front side.
