Forming a patterned primary container molding; After placing the secondary synthetic water support material having a color opposite to that of the first raw material on the surface of the primary molded article, the mold is pressed again to form the same uneven pattern as above. Forming a second container molding in which a second synthetic water support material and a first synthetic main support material form a layered structure and are integrated; Polishing work for polishing the iron pattern of the secondary container molding to form at least a horizontal plane with the recessed pattern to expose the surface of the secondary container molding in a mixed state of two colors. step; And a gloss work step for finishing the surface of the container in which the two colors are matched.

The pattern-forming part of the uneven structure is preferably formed of any one of a figure, a figure, a letter or a combination thereof, such as a curved line, a straight line, a closed curve, a square shape, a circle, and the like as described in claim 2.

In addition, the water support fee, it is preferable to use any one of melamine, plastic and carbonate of claim 3.

In addition, the polishing operation is characterized in that it is carried out by any one of a manual operation by the sand paper of claim 4 or a mechanical operation by the grinder.

In addition, the pattern forming portion of the concave-convex structure is characterized in that it is provided only on the pressing surface of any one of the upper and lower molds of claim 5.

In addition, the synthetic resin container of the present invention for achieving the above object, while forming a molded article of a laminated structure as a synthetic water support material of two different colors as described in claim 6, the inner surface is to make a curved surface as viewed in cross section Claims 1 to 5, characterized in that by forming the curved portion of the curved surface by the grinding process, a pattern of a predetermined shape in which two or more colors are contrasted with each other is formed to the outside. Characterized in that it is produced by the method.

In addition, the mold apparatus for producing a synthetic resin container of the present invention for achieving the above object, while forming the body of the laminated structure by sequentially placing and pressing the synthetic resin support material for the production of containers of different colors of claim 7 of the body The entire surface is characterized in that it comprises a mold provided only on one pressing surface of the pattern forming portion of the concave-convex structure that enables to form a pattern of a predetermined shape in which two mutually contrasting colors are mixed.

The pattern-forming part of the uneven structure is characterized in that any one of a curve, a straight line, a closed curve, a square shape, a circle-like figure, a figure, a letter alone, or a combination thereof.

Hereinafter, with reference to the accompanying drawings will be described in more detail with respect to the synthetic resin container of the present invention, a mold device for producing a container and a container manufacturing method using the device.

First, the synthetic resin container of the present invention will be described with reference to FIGS. FIG. 3 is a cross-sectional view showing only the synthetic resin container molding of the present invention manufactured by the mold, and FIG. 4 is a cross-sectional view after the inner surface of the synthetic resin container molding of FIG. 5 is a real plane photograph of FIG.

As shown in the drawing, the synthetic resin container 100 according to the present invention is used as a food container in a general home, a restaurant, a large restaurant or a catering company, and the synthetic resin container 100 is a synthetic resin of two different colors. In forming the container molding 102 having a laminated structure as a raw material, the inner surface thereof forms the curved surface 107 as seen in cross section, and the curved surface 107 is formed by the formation of the flat portion 104 by polishing. In addition, the primary molding 101 formed therein and the secondary molding 103 positioned on the outer surface of the primary molding 101 form a unique inlay structure as in ceramics, which can be seen together from the outside. . Thus, as shown in FIG. 5, the surface of the container 100 has a structure in which a pattern 108 in which two colors 106a and 106b are contrasted with each other are displayed.

In FIG. 5 according to the embodiment, only the shape of the pattern 108 is formed in a straight line from the center to all directions as an example, but shapes such as curves, closed curves, squares, and circles according to the user's taste, It can be easily understood that pictures, characters alone, or patterns combined with each other can be expressed, and colors are not limited to the colors shown in the examples.

 In addition, although the shape of the synthetic resin container 100 is also shown only to form an oval close to the circular in the above embodiment, as shown in Figures 6a and 6b, the shape or polygonal shape of the rectangular container (100a, 100b) It can be easily understood from Figs. 6A and 6B that a structure can also be made. In addition, as the raw material of the synthetic resin container, melamine, plastic, carbonate and the like are used.

The container 100 having the above structure is manufactured by the mold 200, which will be described with reference to FIGS. 1 and 2. 1 is a cross-sectional view of a mold used for producing a synthetic resin container of the present invention, Figure 2 is a view showing the operating state of FIG.

As shown in the drawing, first, a curved pattern forming part 202 having a concave-convex structure prepares a mold 200 for manufacturing a container provided on one pressing surface 204 (step 1: 300). .

The pattern forming portion 202 of the uneven structure is installed only on the pressing surface 204 of one of the upper and lower molds 201a and 201b, and the pattern forming portion 202 is curved, straight, closed, or square. It is a figure like a circle, a figure, a letter alone, or a pattern combined with each other.

After placing the primary raw material, which is any one of the synthetic water support material (M) for at least two different colors of containers, between the pressing surfaces 204 of the mold 200, the mold 200 is operated to be pressed. As a whole of the inner surface, the pattern forming part 202 obtains the primary molded part 101 in which the uneven pattern of the predetermined shape described above is formed (step 2: 302). As the support fee, the above-mentioned melamine, plastic, carbonate, and the like are used.

On the surface of the primary molding 101, after placing a secondary synthetic water support material that is opposite to that of the first raw material, i.e., having the opposite color, pressurizing the mold 200 again, the surface has the same irregularities as above. While forming a pattern, a secondary molded article 102 and a primary synthetic aid are formed in a stacked structure, and a container molding 102 including an integrated secondary molded part 103 is obtained (step 3: 304).

In order to expose the surface of the container molding 102 in a state in which two colors are mixed, the curved iron and recess patterns of the secondary molding 103 are at least horizontal ( Polishing is performed to achieve the polishing (see Fig. 4) (step 4: 306). For sanding, sand paper or grinder is used.

When the polishing operation is performed, as shown in FIG. 4, the primary molded product 101 formed therein can be seen from the outside as the secondary molded product 103. Therefore, the surface of the container 100 has a structure in which the pattern portion 108 in which two or more colors 106a and 106b contrasted with each other are mixed is visible (see FIG. 5).

The container, which appeared in two colors by polishing, is finally polished to finish the surface cleanly (step 5: 308). After the final gloss work, it is possible to obtain a high-quality, beautifully shaped container, such as in ceramics manufactured by the inlay technique, as shown in the photo substitute drawing of FIGS. 5 and 6.

As described above, according to the present invention, a variety of beautiful and elegant patterns, such as represented in the inlay technique used in the clay container, there is an effect that makes it easy to mass-produce at a low cost and commercially and economical.
