Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a concavo-convex molded article having a concavo-convex pattern on its surface and colored concave or convex portions of the concavo-convex pattern, and a method for producing the same.

[0002]

2. Description of the Related Art Recently, compact products for accommodating cosmetics such as foundations and eye shadows have been diversified to meet the needs of consumers. For example, there are those in which a design is printed on the surface of the container and those in which an uneven pattern is formed on the surface. However, the compact having the above-mentioned pattern has a poor three-dimensional effect, and the compact having the uneven pattern has a three-dimensional effect but a poor color. Therefore, a compact with a concavo-convex pattern having a concavo-convex pattern on the surface and colored concave or convex portions of the concavo-convex pattern is conceivable, which is a combination of both compacts. As a method of manufacturing the compact with an uneven pattern, a method of forming a container having an uneven pattern on the surface in advance and coloring the top surface of the convex portion of the uneven pattern of the container by printing is considered.

[0003]

However, when the compact with the uneven pattern is manufactured by the above method, it is difficult to print on the rising portion of the convex portion, and the color protrudes or deviates from the convex portion of the uneven pattern. .. There is also a method of coloring the concave portion of the container having an uneven pattern with ink or the like, but it has a problem that it takes time and costs increase. Further, as shown in FIG. 13, a film 23 on which an ink layer 22 is formed is placed in a mold 21 having an upper and lower molds and having an uneven pattern 20.
There is a method of filling and molding with a molding material. However, according to this method, the ink layer 22 of the film 23 is easily displaced from the uneven pattern 20 of the molding die 21, and the pattern of the film 23 cannot be easily changed, especially when the shape of the molding die 21 is a curved surface. I have a problem. For this reason, it is difficult to manufacture the above-mentioned compact with an uneven pattern by the conventional manufacturing method.

The present invention has been made in view of the above circumstances, and the concave or convex portions of the concave-convex pattern are accurately colored, the manufacturing cost is low, and the concave-convex pattern is easy to manufacture. The purpose thereof is to provide a formed product and a manufacturing method thereof.

[0005]

In order to achieve the above object, the present invention provides a concavo-convex shaped molded article having a concavo-convex pattern formed on its surface, and the concave or convex portion of the concavo-convex pattern is colored. As a first gist, a film having an uneven pattern formed on the surface is prepared, a surface finishing material layer is formed on the convex part of the uneven pattern of the film, and the above-mentioned is formed on the inner surface of one of the upper and lower molding dies. Place the film backside, close the one mold and the other mold, fill and mold the molding material, and transfer the surface finish material layer to the surface of this molded product. As a gist of 2, a film having an uneven pattern formed on the surface is prepared, and a surface finishing material layer is formed on a predetermined portion (A) or (B) shown below on the back surface of the film, and the mold is divided into upper and lower parts. Of the above film on the inner surface of one mold The third method is the method for producing a molded product with a concavo-convex pattern in which the above-mentioned one mold and the other mold are closed, the molding material is filled and molded, and the surface finishing material layer is transferred to the surface of this molded product. Use as a summary. (A) A portion corresponding to a concave and convex portion. (B) A portion corresponding to the convex portion of the uneven pattern.

[0006]

That is, in the first production method of the present invention, the surface finishing material layer is formed on the convex portion of the uneven pattern on the surface of the film, and the surface of the film is formed on the inner surface of one of the upper and lower molding dies. , The mold is closed and the molding material is filled and molded. As a result, a concavo-convex pattern is formed on the surface, and the concavo-convex pattern formed product is obtained in which the concavities are colored with the surface finishing material layer. In the second manufacturing method, a surface finishing material layer is formed with ink or the like on a predetermined portion of the back surface of the film having an uneven pattern on the surface, and the surface of the film is formed on the inner surface of one of the upper and lower molding dies. To face. Then, the molding die is closed and the molding material is filled.
By filling with the molding material, the top surface of the convex portion of the film adheres to the inner surface of the molding die, and the concave portion of the film adheres to the inner surface of the molding die with the molding material. As a result, a concavo-convex pattern is formed on the surface, and a molded product with a concavo-convex pattern in which the surface portion corresponding to the surface finish material layer is colored is obtained. Therefore, according to the first and second production methods of the present invention, the container with a textured pattern does not have the trouble of aligning the surface finishing material layer formed on the film with the textured pattern of the mold as in the conventional method. Can be obtained. Further, since the surface finish material layer is formed on the back surface or the uneven portion of the surface of the film, it is possible to transfer the surface finish material layer to the molded product without shifting or protruding even if the uneven pattern is fine, It is possible to accurately color the concave or convex portion having the uneven pattern. Further, in the present invention, by changing the pattern of the uneven pattern of the film and the color of the ink of the surface finish material layer, it is possible to obtain a container having a different appearance.

Next, the present invention will be described.

As the film, a thermoplastic resin such as vinyl chloride or polyethylene terephthalate is used. The pattern of convex portions on the surface of the film is integrally formed or is formed on the surface of the film with a thermosetting resin or an ultraviolet curable resin.

An ink layer is formed by printing or a surface finish layer having a metallic luster-like appearance is formed on the predetermined portion of the back surface of the film by printing.

As the molding material, synthetic resin suitable for injection molding, such as ABS resin and propylene resin, is used.

Next, examples will be described.
