Description

[Detailed Description of the Invention] The present invention relates to a decorative product having a glittering curved surface suitable for use in the cap or lid of a container.

For example, in addition to the original function of the container, one of the important elements desired for containers for cosmetics, fragrances, etc. It is one.

Conventionally, methods for decorating containers and caps of this type include ordinary printing, decoration by multicolor molding, decoration by metallic print, and adding diffusely reflective substances such as pearlescent agents into transparent or colored transparent resin materials. Decorating methods are known in which color and luminance shading are made to appear three-dimensionally by mixing, but each of these conventional decorating methods has advantages and disadvantages.

For example, in a decoration method in which a diffusely reflective substance is mixed into a resin material for making plastic molded products,
Although it can give a deep three-dimensional effect to some extent, it is inferior in glitter, and while the decoration method using metallic print is extremely superior in terms of glitter, it can also give a deep three-dimensional effect like a pearl effect. is difficult.

The present invention was developed with the above points in mind, and it has excellent brightness, and the brightness, color shading, and boundaries between them are more clearly expressed, and a three-dimensional effect with sufficient depth can be obtained. The object of the present invention is to provide a decorative article having a glittering curved surface, and a mixed color of the overlapping colored layers of different hues appears on the surface, resulting in an unprecedented decorative surface.

Hereinafter, the present invention will be explained based on an embodiment shown in the drawings.

Fig. 1 shows an example in which the present invention is applied to a container cap.As shown in Fig. 2, this cap A has a spherical surface and an overall AS.
A base material 1 made of synthetic resin such as or ABS resin, glass, or metal, and this base material 1
It is composed of a decorative layer 2 applied to the surface of.

As shown in FIG. 3, the decorative layer 2 includes a light-reflecting metal layer 4 applied to the surface of the base material 1 via an adhesive layer 3 made of acrylic resin, and a light-reflecting metal layer 4 on the surface of the metal layer 4. A light refracting body 6 made of transparent fine spherical particles (such as glass beads) arranged in a single layer through an adhesive layer 5 made of a colored transparent resin, and a colored transparent resin layer 7 applied on the light refracting body 6. , and a transparent protective layer 8 provided on the colored transparent resin layer 7. Further, each of the light refracting bodies 6 has a structure in which approximately the lower half thereof is submerged in the adhesive layer 5, and the remaining upper half is covered with a colored transparent resin layer 7.

The light refractive body 6 has transparency close to colorless,
And the refractive index is 1.60 to 2.30, preferably 1.90 to 1.99 so that the focal point is on the surface of the metal layer 4.
A range of is used. Further, the light-reflective metal layer 4 is formed of a metal having a highly reflective surface such as an aluminum vapor-deposited film or a metal plating film with high reflection efficiency, or anodized aluminum, and the adhesive layer 5 thereon is made of an acrylic-based adhesive layer. It is formed from a colored transparent resin obtained by mixing a suitable amount of dye and pigment into a urethane-based, alkyd-based, or copolymer thereof within a range that does not impair its translucency. Further, the colored transparent resin layer 7 on top of the layer is
For example, it is formed of an acrylic ultraviolet curable resin mixed with a dye and pigment of a different color from the adhesive layer 5 within a range that does not impair its translucency. The transparent protective layer 8 thereon is also made of acrylic or the like, and is formed of a transparent ultraviolet curable resin containing no dye or pigment.
Here, the adhesive layer 5 and the colored transparent resin layer 7
Examples of the colors of dyes and pigments include blue, purple, yellow, edge, orange, and red. Then, for example, the adhesive layer 5 is colored at the edge, and the colored transparent resin layer 7 is colored red. In the figure, reference numeral 9 denotes a female thread that is screwed into a male thread on the outer periphery of the opening of the container body B.
indicate each patchkin.

Next, an example of a method for manufacturing the cap A having the above structure will be outlined. First, a base material 1 having a smooth spherical surface is formed by means such as injection molding, and then a material having adhesive properties to both the base material 1 and metal, such as The adhesive layer 3 is formed by applying a resin adhesive mainly composed of acrylic resin or the like. This adhesive layer 3 is attached to the base material 1
This is not particularly necessary if the metal is made of metal. After forming the adhesive layer 3, aluminum is vapor-deposited thereon to form a highly light-reflective metal layer 4. Then, on this metal layer 4, a colored transparent resin that has been colored in advance is applied to a required thickness to form an adhesive layer 5,
After uniformly scattering the light refractive body 6 made of glass beads thereon, the adhesive layer 5 is hardened at room temperature or forcibly to fix the light refractive body 6. Here, the amount of immersion of the light refractive material 6 into the adhesive layer 5 is determined by the viscosity and degree of curing of the adhesive layer 5, the force applied when spraying the light refractive material 6, etc. Determine the conditions in advance. After the adhesive layer 5 is cured to the required degree, the light refracting body 6 is completely immersed using a thermosetting paint, a thermoplastic paint, and an ultraviolet curable resin paint colored in a color different from that of the adhesive layer 5. A colored transparent resin layer 7 is formed to a thickness of about 100 mL, and a transparent protective layer 8 is further formed thereon using an ultraviolet curable transparent resin material (transparent paint).

According to the embodiment, the light incident on the decorative layer 2 is refracted by the light refracting body 6, reflected by the metal layer 4, further refracted by the light refracting body 6, and then returned toward the light source, but at that time, the light does not stagnate. Agent layer 5 and colored transparent resin layer 7
colored by. For example, if the adhesive layer 5 is yellow and the colored transparent resin layer 7 is red, the relationship between these two colors and the silver color of the metal layer 4 will result in bright, almost orange red light. Therefore, cap A will appear in a color corresponding to that light color.
Cap A, which appears in such a color, has excellent brightness due to the inherent brightness and high reflective action of the metal layer 4, and the shades of color and brightness and the boundaries between them appear more clearly. This results in a three-dimensional effect with sufficient depth. That is, cap A is spherical as shown,
In addition, since the light incident on the decorative layer 2 returns in the direction of the light source and is not diffusely reflected, only that part of the spherical outline of the cap A has another spherical shape with excellent brightness, as shown in Fig. 1. This is because the contour A' appears and the boundary C of this spherical contour A' clearly appears. And this spherical contour A′ is
In particular, in addition to the color mixing effect of the yellow of the adhesive layer 5 and the silver of the metal layer 4, the high glittering effect of the metal layer 4 is added, resulting in the overall appearance of a white, shining gold color. That is, the cap A includes a decorative layer 2 whose surface appears bright and red, close to orange, and whose internal spherical outline A' appears white and shiny gold.

Here, the color tones that appear when the adhesive layer 5 and the colored transparent resin layer 7 are colored in different colors will be described based on experimental results.

[Hue example]

Glue layer 5 → orange Colored transparent resin layer 7 → blue [Result] The surface is blue near the edge, and the spherical outline A' is gold with white spots.

[Hue example]

Glue layer 5 → green Colored transparent resin layer 7 → red [Result] The surface is a pale reddish-purple color, and the spherical outline A' is a pale green color with a white shine.

Note that in both the above two examples and the first embodiment, the color tone of the surface and the spherical contour A' is not just a mixed color, but each hue may be partially or completely depending on the position of the viewer. It was confirmed that the decorative layer 2 is very distinctive in that it appears either strongly or weakly.

In addition, in the examples described so far, both the adhesive layer 5 and the colored transparent resin layer 7 are colored in different hues, but when the manufacturing aspects are taken into consideration when implementing the present invention, It is preferable to set the color of the adhesive layer 5 to a certain color and to create various colors by changing only the color of the colored transparent resin layer 7.

Although the present invention is applied to caps in the embodiments, it is of course applicable to other containers that require excellent decorative properties, such as compact containers. Moreover, if fluorescent dyes and pigments are used as dyes and pigments for coloring the adhesive layer 5 and the colored transparent resin layer 7, the brightness can be further enhanced overall.

As detailed above, according to the present invention, it is possible to have excellent brightness, brightness, color shading, and boundaries between them, giving a sufficiently deep three-dimensional effect. It can effectively enhance decorativeness, which is one of the important elements required for containers, and has a layered structure that allows a variety of colors to be created by changing only the hue of the colored transparent resin layer. Therefore, it has excellent effects such as being extremely convenient in manufacturing. In particular, according to the present invention,
The surface of the base material on which the decorative layer is applied is formed into a spherical surface, and the focal position of the light refractive body is set to be the surface of the metal layer.
Since the incident light on the decorative layer returns in the direction of the light source and is not diffusely reflected, another spherical contour appears within the spherical contour of the base material, which has excellent brightness only in that part, and furthermore, the boundary between this spherical contour Since the parts appear clearly, the decorative effect is greatly enhanced from this point of view as well. Furthermore, since the light refractive material is embedded in the boundary between the adhesive layer and the colored transparent resin layer, in other words, the light refractive material is sandwiched between the upper and lower layers, so to speak, the light refractive material is in the form of fine particles. Nevertheless, it can be easily arranged at the desired position. Therefore, it is extremely easy to set the light refractive body so that its focal point is on the surface of the metal layer 4. Moreover, by embedding the light refractive body at the boundary between the adhesive layer and the colored transparent resin layer, it is possible to easily position the light refraction body, and also to embed the metal layer and the adhesive layer. The color of the colored transparent resin layer is further added to the layer to create a three-color mixture, making the change in hue complex, and thereby creating a new and innovative hue decoration effect that cannot be seen anywhere else.
