Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for manufacturing a synthetic resin article having a decorative surface on the entire surface of the synthetic resin article, such as a compact container for storing cosmetics.

In general, articles made of synthetic resin, such as concrete containers, are designed with a high degree of design and decoration, so ζ is considered important, so some or all of them are decorated with various metallic patterns, etc. to form a decorative surface.In recent years, the above-mentioned 1-decoration surface decorations are increasingly competing for their novelty and am character, and unique, impressive and beautiful ones are required. is the current situation.

This invention was made in view of the above circumstances, and it is possible to give a metallic surface to part or all of a synthetic resin article. ! ! A decorative part is formed by providing convex patterns such as letters and patterns on the surface and OIs other than this pattern, and a glittering part is applied by hot stamping etc. on the flat surface of the upper part of the pattern of this decorative part. A certain colored layer is formed, and a transparent top coat layer is formed on top of that to cover the entire surface of the decorative part, so that patterns such as letters and designs become shiny due to full reflection, and the green looks sharp. An object of the present invention is to provide a method for manufacturing a synthetic resin article having a decorated surface in which a pattern appears to stand out vividly, the rough textured portion exhibits a beautiful iridescent glow due to diffused reflection, and the pattern can therefore be seen more clearly. It is something.

Hereinafter, an embodiment of the first invention will be described using a compact container as shown in the first factor as an article made of synthetic resin. This compact container is integrally molded using a thermoplastic synthetic resin such as ABS, styrene, or acrylic resin by a method such as injection molding. A decoration IS2 is formed on the upper surface of the lid 1 of this compact container. The decorative portion 2 may be formed integrally with the lid portion 1, or may be formed separately and fixed to the upper surface portion of the lid portion 1 with an adhesive or the like. This decorative portion 2 has a metallic surface,
It is formed so that it has a convex pattern 3 such as letters or designs (the letter X in the figure) on its surface, and an uneven texture 4 whose height is lower than that of the pattern 3 in the area other than this pattern 3. A transparent colored layer 5 of a different color is formed on the upper flat surface of the pattern 3 of the decorative portion 2 by hot stamping. The outline of this embodiment is to form a transparent top coat layer 6 on top of this to cover the surface of the decorative portion 20, thereby forming a decorative surface with a new and unique beauty. .

Next, in the above-mentioned part of Nasu, Jin's 11: Example will be explained in more detail.

The decorative portion 2 is formed as follows.

First, as shown in FIGS. 5 and 4, a synthetic resin substrate 7 is formed with the compact container 1 by -V# or by separate molding. A pattern 8 and grains 9 are formed on the surface of this substrate 7. Next, a paste coat layer 1o is formed on the substrate 7.

An aluminum vapor deposited layer (metal layer) 11 is formed on the base coat layer 11 by a vacuum evaporation method.Finally, a transparent or colored translucent overcoat layer 12 is formed on this metal layer 11 to cover the decorative portions. 2 is completed.

As shown in FIG. 6, the different-colored transparent colored layer 5 consists of a transparent colored layer 13 and this transparent colored layer 13 and a different-colored transparent colored layer 14, and as shown in FIG. The transparent colored layers 13 and 14 deposited on the pattern 15 are transferred onto the overcoat layer 12 on the upper flat surface of the pattern 3 using a hot stamping device.

The top coat layer 6 is made of a resin with high surface retention properties, such as a urethane resin or an ultraviolet curing type acrylic resin.

In the compact container (synthetic resin article) formed by K as described above, the pattern 3 is formed in a convex shape, and the transparent colored layer 5 of a different color is formed on this pattern 3. The edge b of pattern 3 looks sharp, the pattern 3 has glittering properties due to total reflection, and the colors appear to be three-dimensional. In addition, by providing the grain 4,
Parts other than pattern 3 are diffusely reflected, exhibiting rainbow-like colors and looking beautiful, and at the same time pattern 3 appears even more prominent.

Therefore, according to the method of the first embodiment, it is possible to manufacture a compact container that can give a new, enviable, and unique impression to the user.

FIG. 7 shows the O implementation N011 part in addition to the first invention, and parts common to FIGS. 1 to 6 are given the same reference numerals as in FIGS. 1 to 6 to simplify the explanation. do. In this embodiment, the method of forming the O part O is the same as that of the first embodiment except for the method of forming the transparent colored layer 50 of a different color formed on the pattern 3 of the decorative portion 20. As shown in FIG. 7, the different-colored transparent colored layer 5 in the ζO embodiment is formed by providing a transparent printing layer 16 colored by K by screen printing on the overcoat layer 12, and applying hot stamping onto this printing layer 1G. A transparent colored layer 14 is provided and formed.

Thereafter, in the same way as described above, a transparent dog coat layer with high surface retention properties is formed on the surface of the decorative portion 20 on top of the different color transparent colored layer 5.

Even if a compact container is formed as in the above embodiment, it is difficult to obtain the same effect as in the tenth embodiment.

Chapter sv! J shows another manufacturing method OII part of the manufacturing method of a synthetic resin article having a decorative surface according to Jin's invention.

The reference numeral 17 in the figure indicates a decorative part, and this decorative part 17 may be integrated with the lid part 1 of the compact container like the decorative part 2 of the above two embodiments, or it may be formed separately. It may be fixed to the upper surface of the lid part 1 using an adhesive or the like. The decorative portion 17 is made of a synthetic resin with a metallic appearance obtained by mixing pigments such as fish phosphorus, flaky bismuth salt, mica or aluminum powder, or a synthetic resin with a pearl-like appearance obtained by polymer blending. 1. A convex pattern 18 such as letters or designs is formed on the surface thereof, and a grain 19 is provided on a portion other than the pattern 18. A colored glitter layer 20 is formed on the pattern 18 of the decorative portion 17 by hot stamping. Finally, a transparent top coat layer 6 is coated and formed thereon with a resin having high surface protection properties such as a urethane resin or an ultraviolet curing type acrylic resin, as in the above two embodiments.

As shown in FIG. 9, the colored glitter layer 20 is composed of an adhesive layer 21, a metal layer 22, and a transparent colored layer 23 laminated in this order, as shown in FIG. 10, on a polyester film 24. A transparent colored layer 23 and a metal layer 2 are sequentially formed.
2. The adhesive layer 21 is laminated and adhered and transferred onto the upper flat surface of the pattern 18 using a hot stamping device. 4゜Even if a compact container is formed in this way, the above 2.
Effects similar to those of the other embodiments can be obtained.

In each of the above embodiments, the decorative portion is formed on the lid portion of the compact container, but it may be formed on other parts, portions, or the entire lid portion of the compact container. By doing so, it is possible to obtain unique decorative effects for each location.

Further, in each of the above embodiments, the present invention was applied to a compact container, but it is also possible to apply it to other synthetic resin articles such as other containers and decorative doors of furniture.

As explained above, according to Jin's invention, patterns such as letters and designs take on a glittering quality, the edges of the pattern appear sharp, the pattern stands out vividly, and the rough textured portions cause light diffraction. It is possible to obtain a synthetic resin article having a new and uniquely beautiful decorative surface, which exhibits a more beautiful iris brilliance and, therefore, a pattern that is more clearly visible.
