Description

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 decorated with a heat-shrinkable film and in which a metallic glossy image appears depending on a container.

[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 can provide a container with excellent aesthetic appearance by a metallic gloss image formed by the metal foil layer. However, when the present invention is applied to a beverage container or the like in which the contents are frequently replaced, the image is always visible, so the change is poor and the user may get bored. Further, since the container exhibits a metallic luster color even when it is not used, the color uniformity and atmosphere of the storage location may be disturbed. Further, a container provided with a reversible thermochromic image is known as a container showing different aspects depending on the contents. The container is one in which the image reversibly changes color depending on the temperature of the contents, and although it has the unexpectedness of color change, it changes color with temperature change.
The color change has a limit depending on conditions such as the temperature of the container and the environmental temperature. Further, as a method of providing the image, provided by a general printing method or transfer method on the container surface,
It is difficult to apply to an uneven surface, and thus is not suitable for providing a desired image in a container having a complicated shape.

[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 make a metallic glossy image appear as needed without having a temperature dependency. Another object of the present invention is to provide a container that does not impair the beauty of the surroundings when stored when not in use, and that can form images of various designs regardless of the shape of the container.

[0004]

According to the present invention, there is provided a heat-shrinkable plastic film comprising a transparent heat-shrinkable plastic film provided with a metallic luster image containing a metallic luster pigment in which mica or a flat glass piece is coated with titanium oxide. A transparent container whose surface is decorated with a shrinkable film, wherein one of transparent to translucent by a metallic glossy image or metallic glossy color is selected depending on the color tone of an object contained in the container. A container that is configured to be visually recognized by the user and that allows the metallic glossy image to appear due to the contents is required. Further, the transparent heat-shrinkable plastic film and the integrated concealment ratio (T
HP) is 0% <THP ≦ 20%, and the transparent container is in the form of a beverage container.

In the present invention, the heat shrinkable plastic film provided with the metallic glossy image is mounted on a transparent container, and then the film is shrunk by heat treatment and fixed to the container. The transparent heat-shrinkable film is provided with a metallic glossy image formed by uniformly dispersing a metallic luster pigment in a transparent resin. In the state where is stored, the transmitted light and the light reflected by the metallic glossy image are mixed, and only a transparent or translucent image is visually recognized. 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 gloss, it is preferable to use a heat-shrinkable film having a low concealment ratio and a container described later. The contents are coffee, tea,
By storing dark colored items such as oolong tea,
The reflection of light transmitted through the image is reduced, and an image with excellent metallic luster can be obtained.

Next, the metallic gloss image will be described. The metallic luster image is applied as a form of a paint, ink or the like in which a metallic luster pigment is dispersed in a binder containing a transparent resin, and is formed on a transparent heat-shrinkable film. The metallic luster pigment in the metallic luster image is uniformly dispersed in the transparent resin.

As the transparent resin, various general-purpose resins can be applied. The resin is preferably a transparent or translucent film-forming resin, and is exemplified below. Ionomer resin, isobutylene-maleic anhydride resin copolymer resin, acrylonitrile-acrylic styrene copolymer resin, acrylonitrile-styrene copolymer resin, acrylonitrile-butadiene-styrene copolymer resin, acrylonitrile chlorinated polyethylene-styrene copolymer resin, ethylene-chloride Vinyl copolymer resin, ethylene-vinyl acetate copolymer resin, ethylene-vinyl acetate-vinyl chloride graft copolymer resin, vinylidene chloride resin, vinyl chloride resin, chlorinated vinyl chloride resin, vinyl chloride-vinylidene chloride copolymer resin, chlorinated Polyethylene resin, chlorinated polypropylene resin, polyamide resin, high-density polyethylene resin, medium-density polyethylene resin, linear low-density polyethylene resin, polyethylene terephthalate resin, polybutylene terephthalate Resin, polycarbonate resin, polystyrene resin, high-impact polystyrene resin, polypropylene resin, polymethylstyrene resin, polyacrylate resin, polymethylmethacrylate resin, epoxy acrylate resin, alkylphenol resin, rosin-modified phenolic resin, rosin-modified alkyd resin, Phenol-modified alkyd resin, epoxy-modified alkyd resin, styrene-modified alkyd resin, acryl-modified alkyd resin, aminoalkyd resin, vinyl chloride-vinyl acetate resin, styrene-butadiene resin, epoxy resin, unsaturated polyester resin, polyurethane resin, vinyl acetate Emulsion resin, styrene-butadiene emulsion resin, acrylate emulsion resin, water-soluble alkyd resin, water-soluble melamine resin It may be mentioned water-soluble urea resins, water-soluble phenolic resin, water-soluble epoxy resins, water-soluble polybutadiene resins.

As the pigment contained in the metallic luster image, a metallic luster pigment in which the surface of natural mica is coated with titanium oxide or a metallic luster pigment in which the surface of a flat glass piece is coated with titanium oxide is preferably used.

As a metallic luster pigment in which the surface of natural mica is coated with titanium oxide, for example, the surface of natural mica is
Coated with 68% by weight of titanium oxide, the coating layer has an optical thickness of 110 to 415 nm and a particle size of 5 to 300 μm
Pigments. The optical thickness of the coating layer in the metallic luster pigment is a refractive index × geometric thickness,
This thickness is related to reflecting light of a certain wavelength, in other words, a specific optical thickness reflects light of a specific wavelength so that a metallic gloss color can be developed.

As the metallic luster pigment, for example, the surface of natural mica particles is coated with 26 to 57% by weight of titanium oxide, the optical thickness of the coating layer is 180 to 240 nm, and the particle size is 5 to 5.
The 125 μm gold metallic luster pigment selectively transmits violet wavelength light and has a complementary color relationship of 550 to 600 nm.
Has the property of reflecting light of yellow wavelength. Therefore, in the state where the container is not contained and in the state where the transparent container is contained, not only yellow light but also violet light is reflected and all wavelengths of visible light are reflected. . In addition, when a colored container is stored, the purple light in the portion where the image is formed is absorbed by the container, and light of a yellow wavelength is reflected, so that a gold image is visually recognized. It is also effective to use a gold metallic luster pigment in which the surface of natural mica particles is coated with titanium oxide and the upper layer is coated with a non-thermochromic dye (preferably 0.5 to 10% by weight). In addition, a change in color from translucent to gold, such as from pink to gold, can also be visually recognized depending on the non-thermochromic dye / pigment to be coated.

When a silver metallic luster pigment is used as the metallic luster pigment, the silver metallic luster pigment causes the surface of the natural mica particles to be 1
The coating layer having an optical thickness of 110 to 170 nm and a particle size of 1 to 180 μm, which is coated with 4 to 43% by weight of titanium oxide, is preferably used. Selectivity can be prevented. Outside the above range, the selectivity of the wavelength of the reflected light occurs, so that the reflected light does not become silver. The titanium oxide layer having the above-mentioned optical properties reflects light of all wavelengths of 380 to 700 nm without being irregularly reflected by the layered arrangement of mica, so that it looks silver. Therefore, in a state where no container is contained and in a state where a transparent container is contained, the image is viewed as being transparent or translucent, and when a colored container is contained, a silver image is visually recognized. Further, as a metallic luster pigment, a metallic luster pigment in which the surface of natural mica particles is coated with titanium oxide, a metallic luster pigment in which the titanium oxide layer is coated with iron oxide, and a non-thermal coating is applied on the titanium oxide coating. Dichroic metallic gloss pigments coated with discolorable colored dyes and pigments can also be used.

Next, examples of metallic luster pigments in which the surface of a flat glass piece is coated with titanium oxide will be described below. As the metallic luster pigment, a product name “Metashine” manufactured by Nippon Glass Fiber Co., Ltd., part number: RCFSX-5450TS (604)

The metallic luster pigment is formed by using a flat glass piece as a core material, and is excellent in transparency as compared with a metallic 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, transparency printing, offset printing, gravure printing, coater, tampo printing, transfer and other printing means, brush coating, spray coating, electrostatic coating, electrodeposition coating, flow coating, dip coating, etc. It can be formed on a film.

As the transparent heat-shrinkable film, general-purpose thermoplastic synthetic resins such as polyester, polystyrene, polyethylene, polypropylene and vinyl chloride are used. When a metallic glossy image is provided on the transparent heat-shrinkable film, the metallic glossy pigment is formed on the film surface (smooth surface) by coating with a metallic glossy ink. The portions are oriented in parallel, and can provide excellent metallic luster. Further, when a metallic glossy ink is applied to the container surface, the content of the metallic glossy pigment contained in the ink is limited, so that it is difficult to form a metallic glossy image having a higher glossiness. When the film is thermally shrunk, the metallic glossy image also shrinks, so that the metallic glossy pigments in the image are densely packed, so that a glossy image which cannot be formed by a conventional printing method can be formed. Further, a fine image having excellent metallic luster can be formed even on a container having irregularities.

The material of the transparent container on which the film is mounted is not particularly limited, but materials such as synthetic resin such as polyethylene and polyester, and glass are used.
As the form of the container, containers for beverages such as cups, tableware,
Containers for cosmetics or medicines, containers for fragrances, containers for ink or black ink, buckets, and various toys are included.

Next, the concealing rate of the transparent heat-shrinkable film and the transparent container will be described. As described above, in order to make the metallic glossy image appear by the contents, the heat shrinkable film and the integrated concealment ratio (TH) of the container are required.
P) is preferably 0% <THP ≦ 20%. This is because the change from transparent or translucent to metallic luster occurs due to the absorption of light in the container.
%, The light that must be absorbed by the container is reflected or absorbed by the film or container itself, so that the metallic gloss image is always visible regardless of the presence or absence of the container. It is because. The color tone of the film or the container is not particularly limited as long as the above-mentioned condition of the concealment ratio is satisfied, and it may be colored transparent or colored translucent. In order to obtain a clearer image, a colorless and transparent material is preferably used.

The definition of the concealment ratio will be described.
The concealment ratio represents the ability to cover and hide the items contained in the container, and the luminous reflectance (Y
Value). As a method of calculating the concealment ratio, the luminous reflectance (Y value) is measured with a color difference meter (TC-3600 color difference meter, manufactured by Tokyo Denshoku Co., Ltd.) by superimposing each of the black and white concealment ratio test sheets on the material. After the measurement, 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 the material W: Superimposing a white background concealment ratio test paper on the material Measured luminous reflectance (Y value) The higher the value of the concealment ratio, the higher the turbidity, and the easier it is for the material to cover and hide the contents. Also, 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 material. 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. The integrated concealment rate (T
HP) represents the sum of the concealment ratios of the film and the container, and is calculated by the following equation. THP = SFHP + PBHP THP: integrated concealment ratio SFHP: concealment ratio of film PBHP: concealment ratio of transparent container

The metallic glossy image includes letters, numbers, symbols, and various designs, and can be provided partially or locally on the heat-shrinkable film, or can be provided dotted. or,
It may be a linear image or a solid pattern covering the entire heat shrinkable film. In addition, the image may be provided with a plurality of images having different shapes and sizes, or provided with images containing different metallic luster pigments, and further, a reversible thermochromic image or a non-thermochromic image may be used in combination. , Can increase the added value of the container.
