DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a container in which a metallic glossy image appears due to a container. More specifically, the present invention relates to a container in which a colored metallic object is contained and a glittering metallic glossy image appears.

[0002]

2. Description of the Related Art A container in which a metal foil layer is provided on the surface of the container has been disclosed (JP-A-61-27300).
The container, even if it is possible to visualize the decorative metallic gloss image formed by the metal foil layer, the container used by frequently changing the contents, for example, in a beverage container, the metallic gloss image is always I was bored with little change because I was sighted. Further, since the container exhibits a metallic luster color even when it is not used, the color uniformity and atmosphere of the place where the container is placed may be disturbed. A container having a reversible thermochromic image on the surface of the container is known as a container showing different aspects depending on the contents. The image of the container is reversibly discolored depending on the temperature of the container, and has an unexpected color change.However, since the color changes with the temperature change, the temperature of the container or the environmental temperature condition There are limitations on discoloration.

[0003]

SUMMARY OF THE INVENTION The present invention is intended to solve the above-mentioned disadvantages of the conventional container, that is, it is possible to easily use a metallic glossy image by using a container without being restricted by the temperature and the place of use. Is intended to provide a container in which 現 appears.

[0004]

According to the present invention, there is provided a metallic glossy image formed by uniformly dispersing a metallic glossy pigment having the surface of a flat glass piece coated with titanium oxide in a transparent resin on the surface of a transparent container. The image changes to any one of transparent to translucent, or metallic luster color depending on the color tone of the container contained in the container, and these aspects are alternatively viewed. A container in which a metallic glossy image appears due to the contents configured as described above is required. Further, the hiding factor of the transparent container is 0% to 20%, the content of the metallic luster pigment in the metallic luster image is 5 to 80% by weight, and the container is a beverage container. Etc. are required.

A description will be given of the metallic glossy image appearing in the container of the present invention. On the surface of the transparent container, a metallic luster image formed by uniformly dispersing a metallic luster pigment obtained by coating the surface of a flat glass piece with titanium oxide in a transparent resin is formed, and the container is placed therein. In the absence state and the state where a transparent container is accommodated, the transmitted light and the light reflected by the metallic glossy image are mixed, and only a transparent or translucent image is visually recognized.
The term “translucent” includes colored translucent. On the other hand, when a colored container is present in the container, the transmitted light is absorbed by the container and only the light reflected by the metallic gloss image is visible, so that the metallic gloss color can be visually recognized. At this time, in order to visually recognize an image having excellent metallic luster, it is preferable to use a container having a low concealing rate of a transparent container itself described later. Also, by storing dark-colored containers such as coffee, black tea, and oolong tea, the reflection of light transmitted through the image is reduced, and an image with excellent metallic luster can be produced.

Next, the metallic gloss image will be described. The metallic glossy image is formed on a transparent container surface by applying a metallic glossy pigment having the surface of a flat glass piece coated with titanium oxide dispersed in a vehicle containing a transparent resin, in the form of an ink or the like. . Further, the metallic luster pigment in the metallic luster image is uniformly dispersed in the transparent resin,
The above-mentioned appearance change is shown.

The metallic luster pigment is formed by using a flat glass piece as a core substance, and is excellent in transparency as compared with a pearl luster pigment in which the surface of mica is coated with titanium oxide. Therefore, it is difficult to determine the color tone of the metallic luster pigment itself in the state where the container is not contained and the state where the transparent container is contained, and the contrast is excellent with the state where the metallic gloss image is visually recognized with the colored container. . In addition, the metallic luster pigment has little angle dependency, so that even if the angle of the container is changed, the color tone of the pigment itself is hardly seen, and a highly commercial container can be provided. The flat glass piece may be a scale-like glass piece.

The metallic glossy image can be obtained by a conventionally known method,
For example, it is formed by printing means such as screen printing, offset printing, gravure printing, coater, tampo printing, transfer, etc., brush coating, spray coating, electrostatic coating, electrodeposition coating, flow coating, roller coating, dip coating, etc. be able to. In addition, the metallic glossy image may be provided directly on the transparent container by means of printing, painting, or the like, or a metallic glossy image may be provided on a film coated with an adhesive, and the film may be attached to the transparent container. .

The material of the transparent container is not particularly limited, but materials such as synthetic resin such as polyethylene, polypropylene and polyethylene terephthalate, and glass are used. In addition, examples of the form of the container include forms of beverage containers such as cups, tableware, containers for cosmetics or medicines, containers for fragrances, containers for ink or ink, buckets, and various toys.

Next, the concealment ratio of the transparent container will be described. As described above, in order to make the metallic glossy image appear in the container, the concealment ratio of the container itself is preferably 0% to 20%. This is because the change from transparent or translucent to a metallic gloss color occurs due to light absorption of the container, and when the concealment ratio of the container exceeds 20% and the transparency is lost, the container absorbs the change. This is because the expected light is reflected or absorbed by the container itself, so that the metallic glossy image may always be visible regardless of the presence or absence of the contained object. still,
The color tone of the container is not particularly limited as long as the above-mentioned condition of the concealment ratio is satisfied, but a colorless container is preferably used in order to further improve the effect of obscuring the above-mentioned metallic glossy image.

The definition of the concealment ratio of the transparent container will be described. The concealment ratio represents a performance of concealing an object contained in a container, and is a value derived from a luminous reflectance (Y value) measured by a color difference meter. As a method for calculating the concealment ratio, a black and white concealment ratio test sheet is superimposed on a container material, and a color difference meter (TC-TC, manufactured by Tokyo Denshoku KK)
After measuring the luminous reflectance (Y value) with a 3600 color difference meter, it is calculated by the following equation. HP = (B / W) × 100% HP: Concealment ratio B: Luminous reflectance (Y value) measured by superimposing a black background concealment test sheet on a container material W: White concealment ratio test paper on a container material The luminous reflectance (Y value) measured in a superimposed manner The higher the value of the concealment ratio, the higher the turbidity and the easier it is for the container to cover and hide the contents. Further, the lower the value of the concealment ratio, the higher the transparency, and the color tone of the stored item can be identified through the container. A white synthetic paper is used as a white background concealment rate test paper, and a black paint applied on the white synthetic paper is used as a black background opacity test sheet. As the concealment rate test sheet, a sheet having a reflectance of 80 ± 1 for a white background and a reflectance of 2 or less for a black background is used.

Next, the content of the metallic luster pigment in the metallic luster image will be described. The content of the metallic luster pigment in the metallic luster image is 5 to 80% by weight, preferably 10 to 80% by weight.
The range of 60% by weight satisfies the practicality. When the content of the metallic luster pigment is less than 5% by weight, it is difficult to obtain a good metallic luster color, and when it exceeds 80% by weight, whitening of the image occurs due to excessive pigment, and the image is hidden by the contents. Becomes difficult to see. The content of the metallic luster pigment represents the weight ratio of the metallic luster pigment to the total weight of the resin, additives and the like forming the metallic luster image and the metallic luster pigment, and excludes volatile components such as solvents.

The metallic glossy image includes letters, numbers, symbols, and various designs, and may be provided partially or locally on the container or may be provided dispersed in dots. Further, it may be a linear image or a solid pattern covering the entire container. Further, the image may be provided with a plurality of images having different shapes or sizes, or provided with an image containing a metallic luster pigment of a different color, or a pearl containing a pearl luster pigment whose mica surface is coated with titanium oxide. A glossy image, a reversible thermochromic image, and a non-thermochromic image can also be used in combination, further increasing the added value of the container.
