Description

Description: TECHNICAL FIELD The present invention relates to a method for producing a pair of plastic ornaments having three-dimensional colored patterns or figures which are associated with each other on the surface.

[Prior Art] Conventionally, coloring pages have been widely known as play tools or teaching materials for young children. As is well known, a coloring picture is composed of a rough sketch in which only the outline of a pictorial pattern is drawn on the rough sketch.
Coloring materials such as crayons are used to create fun and interest in paintings and improve emotional feeling.

A wide variety of colored plastic molded products, whether soft or hard, are commercially available, and various products such as toys, dolls, artificial flowers, and molded fruits are known. These colored plastic molded products can be obtained by punching a colored plastic sheet into a desired shape, or by using a molding die having a desired shape, by injection molding method, compression molding method, extrusion molding method or the like into a plastic material. It is manufactured by a method in which heat, pressure, or both are simultaneously applied to perform molding.

On the other hand, colored printed products of plastic sheets are commercially available. This is, for example, a flower pattern, a feature pattern or the like printed on a plastic sheet with a desired color.

[Problems to be Solved by the Invention] However, since the molded article manufactured by the conventional colored plastic material as described above is manufactured by the mechanical molding method as described above, the shape is defined by the mold. Therefore, the color tone is uniform, and the color tone is almost almost monochromatic, which is a drawback that a monotonous product cannot be obtained.

On the other hand, colored printed products made of plastic sheets had a defect that the colored surface did not give a three-dimensional effect because the surface was flat, and the print peeled off after being rubbed hard or used for a long time. .

The present invention has been made in view of the conventional colored plastic shaped products and the colored printed products of the plastic sheet as described above, and is desired by a conventional cutout technique using a soft colored vinyl chloride resin sheet. Create a cutout picture of the pattern or figure and use the cutout pieces to paint each of the two pictures to the desired color tone with the colored vinyl chloride resin of the same material, to give a completely new surface Manufacture of a pair of plastic ornaments that have three-dimensional colored patterns or shapes that are related to each other and that are soft and have the back surface closely adhered to flat parts such as window glass, door doors, and tiles, which can be enjoyed as ornaments It is intended to provide a method.

(E) After cooling, peel off from the metal plate and softly adhere the back surface to the flat part. Can be flat The method for manufacturing a plastic ornaments consisting of forming on the surface.

Hereinafter, a method for producing a pair of plastic ornaments having a three-dimensional colored pattern or figure related to each other on the surface, which comprises the methods A and B of the present invention, will be described.

First, the method A will be described.

First, a rough sketch of a pattern or figure is drafted on a soft colored vinyl chloride resin sheet with a quick-drying ink or the like, and cut out or punched out along the rough sketch to create a cutout picture. When drafting a draft, you can freely draw the desired pattern or figure, but by copying the original on the colored vinyl chloride resin sheet using the original plate on which the original is drawn, copy the original on the colored vinyl chloride resin sheet You can The rough sketch thus drafted can be cut out by cutting with a cutting tool. It is also possible to create a cut-out picture by punching a colored vinyl chloride resin sheet using a punching tool that has been processed / molded according to the pattern or figure of the rough sketch.

The cutout picture is created by cutting out or punching a soft colored vinyl chloride resin sheet into a desired pattern, figure, character, symbol, or the like, but the color of the colored vinyl chloride resin sheet is not particularly limited. However, a black sheet, a sheet made of a laminate having a black front side and a white back side, for example, is preferable. The thickness of the colored vinyl chloride resin sheet is usually 0.5 mm or more, preferably 0.5 to 2 mm, more preferably 0.8 to 1.5 mm.

Next, the cutout picture is placed on a metal plate and heated to be brought into close contact with the metal plate. The heating is performed by placing the metal plate on a hot plate heated to about 150 to 200 ° C. for 3 to 7 minutes (step a).

After the cut-out picture adheres to the metal plate, take out the metal plate from the hot plate and cool it (process B).

Then, a sol-like colored vinyl chloride resin is filled in the gap portion of the cutout picture on the metal plate for coloring. The method of filling the resin may be to extrude the sol-like colored vinyl chloride resin from the extruded tube and sequentially inject the resin of each color into the gap, or set the extruded tube of the resin of each color once. May be injected into. Further, when the resin is filled, it may be thinner or thicker than the thickness of the cutout picture, but it is performed so as not to cover the cutout picture. Thereby, a three-dimensional colored pattern or graphic can be formed on the surface of the obtained plastic ornament (step C).

In this way, the metal plate on which the colored pattern or graphic is drawn is placed on a hot plate and heated at about 140 ° C to 180 ° C for 5 to 10 minutes to cure the sol-like colored vinyl chloride resin and the same. Colored material The material is fused and integrated with a cutout made of vinyl chloride resin (process d), then cooled with water etc., and the cured colored vinyl chloride resin is peeled from the metal plate to give a soft and three-dimensional coloring to the surface. It is possible to obtain a plastic decorative article having a pattern or a figure, and the back surface of which is formed into a flat plane shape (step E).

Next, the method B will be described.

The cut piece or punched piece of the soft colored vinyl chloride resin sheet obtained when a cut-out picture is prepared by cut-out or punching in the above-mentioned method A is placed on a metal plate and heated to bring it into close contact. The heating is carried out by placing a metal plate on a heated hot plate as in the method A (step a ').

After the cut piece or the punched piece adheres to the metal plate, the metal plate is taken out from the hot plate and cooled (process B).

Then, the sol-like colored vinyl chloride resin is extruded from the tube onto the background of the cutout or punched piece on the cooled metal plate to make it thinner than the thickness of the cutout picture so as not to cover the cutout or punched piece. Alternatively, it is thickly filled and colored to form a three-dimensional colored pattern or figure on the surface and the periphery is colored with a sol-like colored vinyl chloride resin (step C ').

Then, in the same manner as in the above-mentioned method A, the sol-like colored vinyl chloride resin is heated in the same manner as above to be fused together with the cut-out piece or the punched-out piece (step D), and peeled from the cooling mark and the metal plate. As a result, it is possible to obtain a plastic decorative article which is soft and has a three-dimensional colored pattern or figure on the front surface, and the back surface is formed into a flat planar shape (step E).

In the pair of plastic ornaments produced by the above methods A and B, one of the plastic ornaments has a colored pattern or figure, while the other plastic ornament has a colored pattern or figure of silhouette. To be
Both can enjoy the enjoyment as an ornament having colored patterns or figures related to each other.

Next, a pair of tools for making and setting plastic ornaments of the present invention will be described. The production set tool is not necessarily required when it is industrially produced because the necessary materials are set in the apparatus, but it is suitable when it is produced industrially.

As the production set tool, first, the soft colored vinyl chloride resin sheet and a cutout or punching tool for making a cutout picture by cutting or punching along the pattern or figure drawn on the colored vinyl chloride resin sheet are used. To be

The sol-like colored vinyl chloride resin in the production set tool is housed in an extruded tube, and the red, blue, green,
It is possible to use primary colors such as brown, white and black, various semi-transparent colors such as pink, blue, yellow and green, or transparent ones.

As the translucent colored vinyl chloride resin, for example, 100 parts by weight of the transparent vinyl chloride resin is 0.05% of the colored vinyl chloride resin.
Resins containing 3 to 3 parts by weight, preferably 0.1 to 1 part by weight are desirable. When such a translucent colored vinyl chloride resin is applied and adhered on the white vinyl chloride resin, a vinyl chloride resin product having an enamel color can be obtained.

Further, the color of the sol-shaped colored vinyl chloride resin material is not particularly limited to the above, and any color can be selected and used.

As the metal plate, any metal can be used as long as it is a metal that is resistant to rust, but for example, an aluminum plate, a stainless plate, or the like is preferable.

The hot plate is used to heat and cure the sol-like colored vinyl chloride resin material, and the heating means is preferably electrically heated.

The pair of plastic ornaments produced by the method of the present invention described above, which have three-dimensional colored patterns or figures related to each other on the surface, are both soft and the back surface is formed into a flat planar shape. Therefore, the back surface is brought into close contact with a flat portion such as a window glass, a door door, or a tile, and can be used as an indoor ornament. Also, if you cut through a piece of plastic ornaments and cut it with a cutter,
Suitable as a sticker. It can also be used as a store display.

In addition, since a pair of plastic ornaments has a colored pattern or figure of one plastic ornament, and the other plastic ornament has a silhouette colored pattern or figure, the two are related to each other. You can enjoy the fun as a decoration.
