Abstract

PURPOSE:To express a high-grade feeling, and also provide ease of production with a high efficiency by a method wherein a metallic cylinder having a large number of windows on the circumferential wall is fitted on the circumference of a case made of soft metal, and the side-wall of the case is pressed from inside. CONSTITUTION:A case 1 made of aluminum is formed into a cylindrical shape with a top cover, and provided with a shoulder part 1b at a place between the top cover 1a and a sidewall 1c. After the case 1 is press-formed and cleaned, a paint film layer is formed on the surface by painting, and a nearly fan-shape pattern 1d is formed on the sidewall 1c. A register mark 1f is formed on the lower portion of the sidewall 1c. A metallic cylinder 2 has a large number of nearly fan-shape windows 3 which are identical with the pattern 1d, and a register mark 2a is formed at a place corresponding to the register mark 1f. The soft metallic case 1 is inserted into the metallic cylinder 2, and they are placed in a metal mold 4 having a cavity of the same dimension as the outside diameter of the metallic cylinder 2. Then, a rubber body R, which is expanded by hydraulic pressure, is put inside the case 1, and a pressure is applied in it, so that the sidewall of the case 1 is pushed outside and protruded inside the windows 3 of the metallic cylinder 2.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention 1 relates to a cylindrical body for a cosmetic container and a method for manufacturing the same, and particularly relates to a type adapted to a rod-shaped cosmetic container such as a lipstick.

[Conventional technology]

Generally, a rod-shaped cosmetic container such as a lipstick has a cylindrical exterior body with a removably attached lid. This tube is often made of synthetic resin or light metal such as aluminum.

(Problems to be Solved by the Invention) When it comes to cosmetics, in addition to the quality of the cosmetics themselves, the design is also considered to be an important factor in the commercial value of the cosmetics.

For this reason, in the conventional products described above, var powder is dispersed in the synthetic resin raw material, or surface treatments such as hairlines are applied to the metal to give a high-class feel.

However, although these methods can produce products with simple designs, it is difficult to meet a wide range of diversified consumer needs. Additionally, processing such as simply engraving or inserting another material into the engraved part can be considered, but the color would be too strong and mass production would be difficult.

The present invention has been made in view of the above-mentioned matters, and a technical object thereof is to provide a cylinder for a cosmetic container that can express an exceptional sense of luxury and is easy to manufacture, and a method for manufacturing the same.

[Means to solve the problem]

In order to solve the above technical problem, the present invention has the following configuration.

That is, a metal cylinder 2 having a large number of windows 3 formed on the outer periphery of a soft metal cylinder I is tightly fitted.

Then, the side wall portion of the cylinder 1 was bulged into the numerous windows 3 of the metal cylinder 2, thereby forming a cylinder for a cosmetic container.

As for its manufacturing method, a soft metal cylinder I and a metal cylinder 2 in which a large number of windows 3 are formed are prepared.

After fitting the metal cylinder 2 onto the soft metal cylinder 1 and placing it in the mold 4, the side wall of the cylinder I is pressed from inside.

Thereby, the side wall portion of the cylinder I is bulged into the window 3 of the metal cylinder 2, and a cylinder for a cosmetic container is manufactured.

[Effect]

By making the side wall of the cylinder body bulge into the window 3 of the metal cylinder 2, the two metals are integrated, and the textures of the two metals can be combined. Therefore, it is possible to express an exceptional sense of luxury and meet the diversified needs of consumers.

In addition, the product can be completed simply by combining the individually formed metals, eliminating the need for a finishing process, making it easy and efficient to manufacture.

〔Example〕

Embodiments of the present invention will be described based on FIGS. 1 to 4.

The cylindrical body 1 is made of aluminum and is formed into a closed cylindrical shape.
Diameter 17. 'Jm, thickness 0.3++on.

A stepped portion 1 is provided in the area extending from the side wall portion 1c to the canopy portion 1a.
b is formed. This cylindrical body 1 is press-molded, washed, and then coated with a coating layer. A substantially fan-shaped pattern 1d is formed on the side wall portion 1c. Further, a mark If for positioning is formed at the lower part of the side wall portion 1c.

Then, the metal cylinder 2 is tightly fitted into the cylinder l having the above structure.

This metal tube 2 has an inner diameter of 18 mm and a thickness of 0.15 mrQ, and is formed with a large number of substantially fan-shaped windows 3 as shown. The shape of this window 3 matches the pattern 1d, and a mark 2a is formed at a position corresponding to the mark 1f. The interval between the windows is 1.3 mm, and the metal tube 2 has a net-like appearance when viewed as a whole.

Then, with the metal cylinder 2 externally fitted onto the soft metal cylinder l, these are placed in a mold 4 having a cavity with the same dimensions as the outer diameter of the metal cylinder 2, as shown in FIG. Place.

After that, a rubber body R that expands with water pressure is placed inside the cylinder l, and by pressurizing this, the side wall of the cylinder l is pressed from inside, and the side wall of the cylinder l is pressed against the metal cylinder 2. It bulges into window 3.

This amount of bulge does not necessarily have to be the same height as the outer diameter of the metal cylinder 2, and in short, it is sufficient that the cylinder body 1 and the metal cylinder 2 are engaged with each other to the extent that the positions do not shift.

Finally, a gold-plated cap 5 is attached to the top M portion 1a to complete the process.

When forming the window 3 in the metal tube 2, it is not limited to the above-mentioned press punching method, and it goes without saying that the window 3 can be manufactured by an electrolytic casting method or an edge puffer method. Further, the thickness can be appropriately selected from about 0.1 i+m to about 0.2+++ m. Furthermore, the distance between the windows is l.

It can be set arbitrarily between about 2 mm and 1.5 mm.

Further, the side wall portion 1c of the cylindrical body I is not limited to the coating described above, and a film may be formed by roll coating.

Furthermore, in the above embodiment, the rubber is expanded by water pressure and the cylindrical body is
It is made by pushing out a small diameter rubber roller into cylinder 1.
The inner wall may be pressed by rotating the inner wall while being in pressure contact with the inner wall. In the above example, the lid was used as a cosmetic container, but
If the cylinder l is a simple cylinder, it can also be applied to the main body.

〔Effect of the invention〕

According to the present invention, since the textures of two metals can be combined, an exceptional sense of luxury can be expressed, and it is possible to meet the diversified needs of consumers.

In addition, the product can be completed simply by combining the individually formed metals, eliminating the need for a finishing process, making it easy and efficient to manufacture.
