2. Description of the Related Art Conventionally, in a stick-shaped cosmetic container of this type, when the outer cylinder is rotated with respect to the inner cylinder in order to deliver the cosmetic, the inner cylinder is removed from the outer cylinder.
In order to prevent the inner tubular body from coming off, a flange portion is formed so as to project on the outer periphery of the lower end portion of the inner tubular body, while an engaging recess is formed on the inner periphery of the bottom portion of the outer tubular body, The inner cylinder is inserted from below, the flange is engaged with the engagement recess, and then the bottom of the outer cylinder is closed by the bottom cap.

Further, when the outer cylinder is rotated with respect to the inner cylinder, grease or silicon is filled between the outer cylinder and the inner cylinder in order to generate a rotational sliding resistance, thereby smoothing the smoothness. I'm trying to get a good sense of operation.

[0004]

However, in such a conventional bar-shaped cosmetic container, after the inner cylinder is inserted from below the outer cylinder and the flange is engaged with the engagement recess,
Since the bottom of the outer cylinder is closed with a bottom cap,
There is a problem that the bottom cap needs to be manufactured and attached separately, the process is complicated, and the cost is high.

Further, in order to generate a rotational sliding resistance when the inner cylinder and the outer cylinder are rotated, grease or silicon is filled between the outer cylinder and the inner cylinder. Another problem is that the manufacturing process is complicated.

The present invention has been made in view of the above problems, and an object thereof is to prevent the inner cylinder from coming off from the outer cylinder, and to assemble the inner cylinder from above in the outer cylinder. It is possible to simplify the process, and also to omit filling grease or silicon to generate the rotary sliding resistance. Moreover, these two functions of the slip-out prevention and the rotary sliding resistance can be efficiently combined. It is an object of the present invention to provide a stick-shaped cosmetic container that can be integrally configured into one component.

It is characterized in that an inner component having an elastic flexible portion that rides over the locking projection and having a fitting concave portion for sandwiching the locking projection in the vertical direction is mounted inside the elastic flexible portion.

Further, a protrusion projecting outward from the cosmetic dish cylinder to which the rod-shaped cosmetic is mounted is attached to the inner dish body through a vertical slit of the inner cylinder body attached to the cosmetic dish dish. By engaging with the spiral groove of the attached outer cylindrical body and rotating the outer cylindrical body, the protrusion is moved along the spiral groove while being guided by the vertical slit, and the outer cylindrical body is moved. On the other hand, in the stick-shaped cosmetic container in which the cosmetic dish cylinder is slidably moved in the vertical direction, between the inner cylinder body and the outer cylinder body, a ring shape surrounding the inner cylinder body is formed, and The present invention is characterized in that a filling is formed in which an elastic flexible portion that elastically contacts the outer peripheral surface of the inner cylinder is formed.

Further, a protrusion projecting outward from the cosmetic dish cylinder on which the rod-shaped cosmetic is mounted is attached to the inner dish body through the vertical slit of the inner barrel body attached to the cosmetic dish dish. By engaging with the spiral groove of the attached outer cylindrical body and rotating the outer cylindrical body, the protrusion is moved along the spiral groove while being guided by the vertical slit, and the outer cylindrical body is moved. On the other hand, in a bar-shaped cosmetic container in which the cosmetic dish cylinder is slidably moved in the vertical direction, an outwardly projecting locking projection is formed at a position above the vertical slit of the inner cylindrical body, and the inner cylinder is formed. Between the body and the outer cylinder body, there is formed a ring shape surrounding the inner cylinder body, and having an elastic flexible portion that rides over the locking projection and elastically contacts the outer peripheral surface of the inner cylinder body, A fitting concave portion for sandwiching the locking projection from the up and down direction is formed inside the elastic flexible portion. Characterized in that the middle member is mounted.

According to the rod-shaped cosmetic container of the present invention having the above-mentioned structure, the fitting recess formed inside the elastic flexible portion of the filling is fitted to the locking projection of the inner cylinder, After that, by assembling the inner tubular body with the inner component attached from above the outer tubular body, and by mounting this inner component between the inner tubular body and the outer tubular body, the inner tubular body can be prevented from coming off, and therefore the bottom portion of the outer tubular body can be prevented. No bottom cap is required to close and the manufacturing process is simplified.

According to the stick-shaped cosmetic container of the second aspect of the invention, the elastic flexible portion of the filling elastically contacts the outer peripheral surface of the inner cylindrical body to rotate the outer cylindrical body for delivering the cosmetic. It is possible to generate a rotational sliding resistance when it is performed, and it is possible to guarantee a smooth cosmetic material dispensing operation without filling grease or silicone between the outer cylinder body and the inner cylinder body.

Further, according to the stick-shaped cosmetic container of the present invention of claim 3, the above-mentioned two functions can be combined into one component called an inner tool in a highly functional form, and the stick-shaped cosmetic container has good manufacturability. A cosmetic container can be provided.

Since it is characterized by mounting the filling with the recess formed,
The inner tool is mounted between the outer cylindrical body and the outer cylindrical body with the fitting recess inside the elastic flexible portion of the inner tool sandwiched from above and below the locking protrusion of the inner cylindrical body. It can be prevented from coming off. At this time, the inner cylinder can be assembled into the outer cylinder from above, so that a bottom cap for closing the bottom of the outer cylinder is unnecessary, and the manufacturing process can be simplified.

In addition, between the inner cylindrical body and the outer cylindrical body, there is provided a filling material which is formed in a ring shape surrounding the inner cylindrical body and which has an elastic flexible portion elastically contacting the outer peripheral surface of the inner cylindrical body. Since the elastic flexible portion of the filling is elastically contacted with the outer peripheral surface of the inner tubular body, the outer tubular body is rotated to obtain the rotational sliding resistance when the cosmetic is delivered. As a result, it is possible to ensure a smooth dispensing operation of cosmetics without filling grease or silicone between the outer cylinder body and the inner cylinder body as in the conventional case.

Further, a locking protrusion is formed by projecting outward at a position above the vertical slit of the inner cylinder, and is formed in a ring shape surrounding the inner cylinder between the inner cylinder and the outer cylinder. Which has an elastic flexible portion that surmounts the locking projection and elastically contacts the outer peripheral surface of the inner cylindrical body, and has a fitting recess formed inside the elastic flexible portion to sandwich the locking projection from the vertical direction. Since it is characterized by mounting the above, the two functions of preventing the inner cylindrical body from coming off from the outer cylindrical body and imparting rotational sliding resistance when the outer cylindrical body is rotated are included in one component called a middle tool. It has an excellent effect that it is possible to provide a stick-shaped cosmetic container that can be collectively configured in a highly functional form and has good manufacturability.
