Abstract

PURPOSE:To obtain a molding with an uneven pattern which can be colored exactly in an inlaid manner upon molding by a method wherein the uneven pattern is formed on the surface and the depressed part of the uneven pattern has its bottom colored and a transparent resin filled therein. CONSTITUTION:An uneven pattern 9 is formed on the surface of film 6 in a manner wherein a plurality of raised parts 9a, each consisting of a ultraviolet curable resin 4, a surface finishing material layer 3 constituted of the ink printed on this resin and an adhesive agent layer 5, are freely detachably attached to the film surface and this film 6 is placed into a molding die 16 to produce a molding having an uneven pattern 2 formed on its surface. In this way, the molding having depressed parts 2a colored with the surface finishing material layer 3 and the ultraviolet curable resin 4 in an inlaid manner is obtained. This method gives a container thus formed an inlaid design colored with the surface finishing material layer 3 and the ultraviolet curable resin 4 with the inlaid parts matching exactly with the depressed parts 2a of the uneven pattern 2.

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 indented coloring on the concavo-convex pattern, and a method for producing the same.

[0002]

2. Description of the Related Art Recently, compacts 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 having 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 shifts 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. Moreover, there is a problem that it is difficult to give a glittering color (decorating in an inlaid pattern) with the uneven pattern colored in this way. Therefore, as shown in FIG. 7, a film 23 on which an ink layer 22 is formed is placed in a mold 21 having upper and lower molds and having an uneven pattern 20, and in that state, a molding material is filled to form a molded product. Is molded, and then a transparent resin material is poured into a concave portion of the above-mentioned molded product having an uneven pattern (the above-mentioned ink layer 22 is transferred to this concave portion) to be solidified. 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. Moreover,
After molding the molded product, the resin material has to be poured into the recesses of the uneven pattern of the molded product to be solidified, which is very troublesome. 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 an object thereof is to provide a molded product with an uneven pattern in which concaves of the uneven pattern can be accurately colored during molding, and a manufacturing method thereof. To do.

[0005]

In order to achieve the above-mentioned object, the present invention has an uneven pattern formed on the surface, and the bottom of the concave part of the uneven pattern is colored and a transparent resin is provided in the concave part. The first gist is a molded product with a concave-convex pattern filled with the above, and a film on the surface of which a convex portion made of a transparent resin is detachably formed is prepared, and a surface finishing material layer is formed on the convex portion of the film. Is formed, and the surface of the film is arranged facing the inner surface of one mold of a molding mold that is divided into upper and lower parts, and the one mold and the other mold are closed to fill and mold the molding material,
A second gist is a method for producing a molded product with a concavo-convex pattern in which the surface finish material layer and the convex portions are transferred to the surface of the molded product.

[0006]

That is, in the manufacturing method of the present invention, a convex portion made of a transparent resin is detachably formed on the surface of the film, and a surface finishing material layer is formed on the convex portion, so that one of the upper and lower molding dies is separated. After arranging with the surface of the film facing the inner surface of the mold, the molding die is closed and the molding material is filled and molded. As a result, an uneven patterned product is obtained in which an uneven pattern is formed on the surface, the bottom of the concave is colored with the surface finish material layer, and the transparent resin is filled in the upper part thereof. Therefore, according to the manufacturing method of the present invention, the complicated work of aligning the surface finishing material layer formed on the film with the uneven pattern of the molding die as in the conventional method, and the molded product after molding the molded product It is possible to obtain a molded product with an uneven pattern without the troublesome work of pouring a resin material into the concave part of the uneven pattern formed in the above. Further, since a convex portion made of a transparent resin is detachably formed on the surface of the film and the surface finishing material layer is formed on the convex portion, even if the uneven pattern is fine, it may be displaced or protruded. It is possible to transfer the resin and the surface finishing material layer to a molded product without using the resin, and it is possible to accurately color the concave and convex portions in an inlaid pattern. Furthermore, in the present invention, when the color of the ink of the uneven pattern or the surface finish material layer of the film is changed,
Containers of different appearance can be obtained.

Next, the present invention will be described.

As the film, a thermoplastic resin such as vinyl chloride or polyethylene terephthalate is used. Then, on the surface of the film, a convex portion is formed by a thermosetting resin or an ultraviolet curable resin by silk screen printing or the like so as to be detachable.

On the convex portion of the surface of the film, an ink layer is formed by printing or a surface finish material layer having a metallic luster is formed by metal deposition.

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

Next, examples will be described.
