By rotating the outer cylinder 56 and the knob portion 51 relative to each other, the stick-shaped cosmetic material 55 appears and disappears.

A cap (not shown) is detachably attached to the outer cylinder 56.

[Problems to be solved by the device]

However, in the above-mentioned conventional one, since the base portion 53 for supporting the stick-shaped cosmetic material is substantially fixed to the container, when the same strong impact that drops the container is given, the shock is applied. Directly transmitted to the cosmetics 55, 5
5 may be pulled out, or the head of the stick-shaped cosmetic material 55 may come into contact with the ceiling of the cap, resulting in a marked decrease in commercial value.

The present invention has been made in view of the above matters, and even when a strong impact is applied to the container, the stick cosmetic does not break or pull out, and the head of the stick cosmetic does not contact the cap. It is a technical object to provide a stick-shaped cosmetic container having such a structure.

[Means for Solving the Problems]

In order to solve the above technical problems, the present invention accommodates an inner cylinder 2 in an outer cylinder 1 so as to be rotatable in the circumferential direction thereof, and a receiving tray 4 for holding a stick-shaped cosmetic material 3 in the inner cylinder 2. A spiral groove 5 is provided slidably on the inner surface of the outer cylinder 1, a linear groove 6 is formed in the inner cylinder 2 in the axial direction thereof, and the linear groove 6 is penetrated through the receiving tray 4. Then, the engaging dowel 7 engaging with the spiral groove 5 is projected, and the inner cylinder 2 is rotated with respect to the outer cylinder 1 to guide the engaging dowel 7 by the spiral groove 5 and the linear groove 6. The receiving tray 4 is slid so that the stick-shaped cosmetic material 3 is fed out from the upper end opening of the outer cylinder 1 in the following configuration.

That is, the lower end of the spiral groove 5 is provided with the floating groove 8 extending in the axial direction of the outer cylinder 1.

A guide groove 6a corresponding to the floating groove 8 is continuously provided at the lower end of the linear groove 6, and a buffer 9 is provided inside at least one of the floating groove 8 and the guide groove 6a to form a stick-shaped cosmetic container. .

[Action]

At the bottom dead center position of the receiving tray 4, the engaging dowels 7 formed on the receiving tray 4 can move up and down in the floating groove 8 and the guide groove 6a. Since the buffer body 9 is provided in the floating groove 8 or the guide groove 6a, the engagement dowel 7 abuts on the buffer body 9 and is elastically supported.

Therefore, the receiving tray 4 can move up and down to absorb the impact when there is a shock from the outside, and the impact is not transmitted to the stick-shaped cosmetic material 3 supported by the receiving tray 4.

When the receiving tray 4 is lifted from the bottom dead center position, that is, when the stick-shaped cosmetic material is fed out, the engaging dowel 7 separates from the guide groove 6a, so that the cushioning function is lost, and play or an unstable state occurs It never happens.

As described above, even when a strong impact is applied to the container, there is no possibility that the stick-shaped cosmetic material is broken or the head of the stick-shaped cosmetic material abuts on the cap or the like.

〔Example〕

An embodiment of the present invention will be described with reference to FIGS.

This embodiment is a lipstick container in which an inner cylinder 2 is rotatably housed in an outer cylinder 1 and a receiving tray 4 holding a stick-shaped cosmetic material 3 in the inner cylinder 2 is slidable. It is provided. A bottom cap 20 and an inner cap 20a located inside the bottom cap 20 are attached to the bottom of the inner cylinder 2, and a decorative ring 21 is externally fitted to the central portion of the outer cylinder 1. A cap 22 is attached to the outer cylinder 1.

A spiral groove 5 is provided on the inner surface of the outer cylinder 1, and a lower end of the spiral groove 5 has a floating groove 8 extending in the axial direction of the outer cylinder 1.
Are lined up. The floating groove 8 is formed by extending the lower end of the spiral groove 5 in both up and down directions.

The inner cylinder 2 provided inside the outer cylinder 1 is formed with a linear groove 6 extending in the axial direction thereof, and a guide groove 6a corresponding to the floating groove 8 is continuously provided at the lower end of the linear groove 6. Has been done. The guide groove 6a is configured such that the lower end of the linear groove 6 extends in the circumferential direction of the inner cylinder 2 and the tip of the extending portion extends in the axial direction of the inner cylinder 2. On the other hand, an extension groove 6b is formed at the upper end of the linear groove 6 in a direction opposite to the extension direction of the lower end.

In the first embodiment shown in FIG. 2 (a), sponge cushions 9 are provided at the upper and lower ends of the floating groove 8.

The receiving tray 4 has a bottomed tubular shape, and an engaging dowel 7 is formed on the side surface thereof. The engaging dowel 7 penetrates the linear groove 6 and engages in the spiral groove 5.

Then, by rotating the inner cylinder 2 relative to the outer cylinder 1, the engagement groove 7 is guided by the spiral groove 5 and the linear groove 6, and the receiving tray 4 is received.
To move the stick-shaped cosmetic material 3 from the upper end opening of the outer cylinder 1.
