Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a stick-shaped cosmetic extrusion container, and more specifically, an object of the present invention is to enable the container to be manufactured at a lower cost without deteriorating its mechanical strength. It is something to do.

Various structures have been put into practical use as rod-shaped cosmetic extrusion containers, but an outer cylinder is attached to an inner cylinder so that it can rotate freely but cannot be removed, and a rod-shaped cosmetic is directly mounted and held in the inner cylinder. The tray body is assembled so as to be movable up and down, and the tray body is moved up and down by the relative rotation of the inner cylinder body and the outer cylinder body, and the bar-shaped cosmetics held in the tray body is lifted from the inner cylinder body. Those configured to be put in and taken out are the most commonly used because of their simple structure, ease of use, and ability to store and hold bar-shaped cosmetics that are larger than their size. has been done.

FIG. 1 shows a typical structure of a conventional bar-shaped cosmetic extrusion container having the above-mentioned structure.

In this Figure 1, 1 has a straight cylindrical shape,
It is an inner cylindrical body formed with a vertical hole 3 for a guide formed over almost its entire length, and the outside of this inner cylindrical body 1 is made of metal in the shape of a straight cylinder with a screw groove 8 carved on the inner peripheral surface. The outer cylindrical body 7 is rotatably attached but cannot be removed.

The means for assembling the outer cylinder 7 to the inner cylinder 1 is not particularly limited, but in the illustrated embodiment, the outer cylinder 7 is attached to the upper end of the outer peripheral surface of the inner cylinder 1. A locking circumferential strip 2 for locking from above is provided at the upper end, and a handle portion 1' with a large outer diameter is integrally provided at the lower end of the inner cylinder 1, thereby making it possible to connect the main body portion of the inner cylinder 1 and the handle portion 1. The lower end of the outer cylindrical body 7 is brought into contact with the stepped portion 4 formed between the outer cylindrical body 7 and the outer cylindrical body 7.

It goes without saying that the inner diameter of the outer cylindrical body 7 is set to be the same as or slightly larger than the outer diameter of the inner cylindrical body 1.

A handle tube 5 is assembled and fixed to the handle portion 1' to form a larger handle portion so that handling of the bar-shaped cosmetic extrusion container is convenient.

The handle tube 5 has an inner diameter larger than the outer diameter of the outer tube body 7, and a metal decorative tube piece 6 is assembled and fixed to the upper end of the handle tube 5 in order to create a more effective decorative effect. has been done.

As described above, this type of conventional bar-shaped cosmetic extrusion container uses the decorative tube piece 6 in order to obtain a better decorative effect on its appearance. In addition, the number of parts constituting the bar-shaped cosmetic extrusion container increases, which increases the number of man-hours required to assemble the bar-shaped cosmetic extrusion container, and the unit price of the metal decorative cylinder piece 6 is by no means cheap. As a result, the unit cost of parts required to assemble the bar-shaped cosmetic extrusion container is high, resulting in an inconvenience that increases the cost of the bar-shaped cosmetic extrusion container.

The present invention was devised in order to eliminate the drawbacks and inconveniences of the conventional examples described above, and by utilizing the fact that the outer cylinder body 7 is made of metal, the metallic feel of the outer cylinder body 7 is different from that of the conventional decorative cylinder. It is constructed to have a decorative effect in place of the piece 6.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.

The rod-shaped cosmetic extrusion container according to the present invention has an inner cylindrical body 1 having a vertical hole 3 formed therein over almost its entire length.
An outer cylindrical body 7 having a threaded groove 8 carved on its inner circumferential surface is fitted and assembled so that it can rotate freely but cannot be removed, and the tip of a shaft piece 10 protruding from the outer circumferential surface is fitted into the inner cylindrical body 1. is a rod-shaped cosmetic extrusion container which is assembled so as to be movable up and down by sliding a saucer body 9 which passes through the vertical hole 3 and fits into the screw groove 8, and wherein the outer cylinder body 7 is made of metal. At the same time, a circumferential protrusion 11 is provided on the outer cylindrical body 7 at an appropriate height position by bending the cylindrical wall of the outer cylindrical body 7 and protruding outward.

That is, as shown in FIG. 2, a metal cylinder, which is the base body of the outer cylinder 7 having a linear cylindrical shape, is drawn at a desired height position to form a peripheral protrusion 11. A threaded groove 8 is formed by cutting on the inner circumferential surface of the metal cylindrical body on which the protrusion 11 has been formed, and an outer cylindrical body 7 is formed.
It molds.

As described above, by providing the peripheral protrusion 11 on the outer cylindrical body 7, the external appearance of the bar-shaped cosmetic extrusion container can be made exactly the same as the conventional example shown in FIG. The protrusions 11 are integrally formed with the metal outer cylinder 7, and can be given the same decorative effect as the conventional decorative cylinder piece 6.

Now, as a means for forming this circumferential protruding strip 11, a method such as drawing is used, but whatever method is used, a part of the cylindrical wall of the outer cylindrical body 7 is bent to form the circumferential ridge 11. Since the circumferential protrusions 11 are formed, by forming the circumferential protrusions 11, the circumferential concave grooves 12 are formed on the inner circumferential surface of the outer cylinder 7 integrally with the circumferential protrusions 11. .

However, since the spiral groove 8 is carved on the inner circumferential surface of the outer cylinder body 7 where the circumferential groove 12 is formed,
The threaded groove 8 and the unnecessary circumferential groove 12 are integrally formed on the inner circumferential surface of the formed outer cylinder 7, which prevents the movement of the shaft piece 10 along the threaded groove 8. In other words, there is a risk that the vertical movement of the saucer body 9 will be hindered.

The means shown in FIG. 3 and the means shown in FIG. 4 are conceivable as means for preventing the adverse effect of the circumferential groove 12 on the movement of the tray body 9.

The means shown in FIG. 3 has a structure in which the thickness of the shaft piece 10 along the spiral direction of the spiral groove 8 is made sufficiently larger than the groove width of the circumferential groove 12.

In this case, since the thickness of the shaft piece 10 along the helical direction of the spiral groove 8 is sufficiently larger than the groove width of the circumferential groove 12, the shaft piece 10 that was loosely engaged with the spiral groove 8 is
Also, the shaft piece 10 does not get caught in the recess formed in the screw groove 8 by intersecting the circumferential recessed grooves 12, thereby making the saucer body 9 smooth. This makes it possible to obtain moving motion.

The means shown in FIG. 4 is to form a circumferential protrusion 11 and a circumferential groove 12 on a metal cylindrical body, which is the base body of the outer cylinder 7, and then apply a pressing force to this cylindrical body from above and below. The portion of the circumferential protrusion 11 is bent and deformed by the pressing force so that the circumferential groove 12 is closed, and the spiral groove 8 is cut and formed on the inner circumferential surface of this cylindrical body to form the outer cylindrical body 7. It has become a composition of the following.

In this case, since the circumferential groove 12 is hardly open to the inner circumferential surface of the outer cylinder 7, a defect such as the shaft piece 10 getting caught in the circumferential groove 12 may occur. There is no risk of movement occurring.

As described above, in the present invention, the circumferential protruding strip 11 is integrally molded on the metal outer cylinder 7, and the circumferential protruding strip 11 can function as a part that produces a decorative effect using a metallic feel. Therefore, this circumferential protruding strip 11 can function as one that exhibits exactly the same decorative effect as the conventional decorative tube piece 6.

Furthermore, since the circumferential protruding strip 11 is integrally molded with the outer cylinder body 7, no structure is required for assembling the circumferential protruding strip 11, and the overall structure becomes simpler.

Furthermore, since the number of parts that make up the container is small, the assembly process is simpler and takes less time.
Furthermore, the occurrence of incorrect work is extremely reduced.

Furthermore, since the number of parts is small, the costs required for the parts are correspondingly low, and the entire container can be manufactured at a lower cost.

As is clear from the above description, the bar-shaped cosmetic extrusion container according to the present invention has an extremely small number of parts, which simplifies assembly work and reduces material costs, making this type of container extremely popular. It can be manufactured at a low cost and has excellent effects, such as being able to obtain the same decorative effect as conventional metals.
