The restraining cylinder 26 is erected, and the outer peripheral surface of the restraining cylinder 26 is located inside the lower portion of the receiving tray 30 at the lowest position in the inner cylinder 20, and the receiving tray 30 The stick-shaped cosmetic container was formed so as to prevent the portion provided with the projection 36 from bending inward.

Further, as a means for preventing the engagement step portion of the inner cylinder from coming off from the retaining step portion of the outer cylinder, a restraining bottom cylinder 35 extending downward from near the lower portion of the receiving tray 30 is provided, and the inner cylinder 20 The outer peripheral surface of the suppression bottom cylinder 35 of the receiving tray 30 at the lowest position in
Located inside the portion of the inner cylinder 20 provided with the engagement step portion 25, formed to prevent the portion provided with the engagement step portion 25 from bending inward, and a stick-shaped cosmetic container. did.

[Action]

In the stick-shaped cosmetic container of the present invention, when the outer cylinder 10 is rotated to one side with respect to the inner cylinder 20, the projection 36 is inserted into the vertical hole 22 of the inner cylinder 20 and the spiral groove 11 of the outer cylinder 10 is inserted. Receiving tray 30
The protrusion 36 is prevented from rotating by the vertical hole 22 and pushed up by the spiral groove 11 of the outer cylinder 10, and the stick-shaped cosmetic material mounted on the receiving tray 30 projects outward from the upper end of the inner cylinder 20.

When the outer cylinder 10 is rotated to the other side with respect to the inner cylinder 20 from which the stick-shaped cosmetic material projects, the protrusion 36 of the receiving tray 30 is prevented from rotating by the vertical hole 22 of the inner cylinder 20, and It is pulled back by the spiral groove 11 of the cylinder 10.

The vertical movement of the receiving tray 30 is the same as the conventional one.

Further, when the receiving tray 30 is pulled back to reach the lowest position in the inner cylinder 20 and the projection 36 reaches the end point of the spiral groove 11 of the outer cylinder 10, the projection
In the receiving tray 30, the portion of the receiving tray 30 provided with the protrusion 36 is bent inward to try to get over the end point of the spiral groove 11.
The inside of the portion where the protrusion 36 is provided is restrained by the restraining cylinder 26, does not bend, and the protrusion 36 of the receiving tray 30 does not come off from the spiral groove 11.

Further, when the receiving tray 30 is pulled back into the inner cylinder 20 and the stick-shaped cosmetic material is accommodated and the stick-shaped cosmetic container is dropped upside down on the floor or the like, the inner cylinder 20 is engaged. The portion provided with the step portion 25 is bent inward to prevent the outer tube 10 from coming off the step portion 13 and the inner tube 20.
Even if the engaging step 25 of the
Inside the portion where 25 is provided, a bottom cylinder 35 for suppressing the receiving tray 30 is provided.
Therefore, the inward bending of the portion provided with the engagement step portion 25 is suppressed, and the engagement step portion 25 does not come off from the retaining step portion 13 of the outer cylinder 10.
