Description

[Detailed Description of the Invention] Industrial field of application The present invention relates to a cup with a thermochromic pattern. More specifically, the present invention relates to a thermochromic pattern in which the color tone of the same contour pattern is different due to a temperature change, and a cup with a thermochromic pattern which is configured to make a non-color-changing image visible alternately.

2. Description of the Related Art Several attempts have been made in the past to provide a thermochromic layer on the surface of a cup to change the color according to the temperature of the beverage (Shokaisho 62
-50999 publication).

Problems to be solved by the present invention The present invention conceals a plurality of patterns and discolored images of different shapes due to temperature changes, and even if the taste of discoloration and interest is further enhanced, it is possible to visualize the approximate temperature. It is intended to provide a convenient cup with a thermochromic pattern.

Technical Means for Solving Problems The constitution of the cup of the present invention will be described in detail below. (See FIG. 1 to FIG. 5) In the present invention, the non-color-change image 3 is printed on the surface of the cup 2 and the image 3 is covered, and the color-changing temperature and the outline 41 of the pattern are arranged in a cut state. A plurality of reversible thermochromic pigments having different color tones at the time of color development are fixed on the reversible thermochromic pigment in a fixing resin in a dispersed state, and the reversible thermochromic pattern layer 4 is overprinted. The color-changing pigment changes its color stepwise at each color-changing temperature to present different colors, and the visual density at each step is set to a density exceeding the visual density of the non-color-changing image 3 and is the same depending on the temperature change. Cup 1 with a thermochromic pattern, which is configured so that the thermochromic pattern 3 in which the color tone of the contour pattern 41 is different and the non-color-changing image 3 are seen alternately
Is a requirement.

In the above, the non-color-changing image 3 is a printed image with a general dye / pigment ink, and examples thereof include designs, characters, alphanumeric characters, and symbols.

The reversible thermochromic pattern layer 4 is a contour of a pattern formed by printing with an ink using a thermochromic material in which a plurality of reversible thermochromic pigments having different color changing points and different color tones from each other are dispersed in a fixing resin. The pattern 41 is a layer formed in a punched state.
The removed state means a state in which a layer is not formed (no ink is attached) at that portion and the shape is concave with respect to the surroundings. The design in the above includes symbols and characters. Specifically, the non-color-changing image 3 and the pattern in the reversible thermochromic pattern layer 4 have a mutually related combination (for example,
Vehicles, buildings, old and new of various products, customs, history changes, seasons, changes of features, patterns that are mutually or opposing each other, letters, symbols, phrases, sentences, etc., and the like have a wonderful change Although effective, any combination may be used as long as it satisfies the setting requirements of the above configuration.

As the reversible thermochromic material, conventionally known materials are effective. For example, an electron-donating color-developing organic compound, a developer of the compound, and a color-changing temperature adjustment for determining the temperature at which the color reaction between the two compounds occurs. A thermochromic pigment consisting of three components of an agent or a pigment exhibiting thermoreversible thermochromic properties in the form of fine particles of a resin solid solution of the above components, and the like, and a suitable example of which is previously proposed by the present applicant. No. 51-44706, Japanese Patent Publication No. 51-44708
The thermochromic material disclosed in Japanese Patent Publication No. 52-7764, Japanese Patent Publication No. 51-35414, etc. can be used.

Action The reversible thermochromic pattern layer 4 is decolorized at or below a predetermined temperature, and in the color-developed state, the density is higher than the visual density of the non-color-changed image 3, so that the non-color-changed image 3 is hidden. The outline pattern 41 of the pattern in the removed state is not visually recognized. on the other hand,
When the pattern layer 4 is in the decolored state, the concealed state is released and the non-color-change image 3 is made visible.

Since the change of the appearance is reciprocal and reversible, it can be reproduced and visualized repeatedly, and the pattern layer 4
Since the color changes gradually and exhibits different colors, the visual change can be further diversified.

Example (see FIGS. 1 to 5) A modern streamline train pattern 3 was arranged by screen printing using a non-color-changing ink in which a light brown pigment was dispersed in a suitable position on the outer peripheral surface of a white ceramic cup 2. After that, reversible thermochromic ink [Orange colorless (30 ° C), blue colorless (40 ° C), red colorless (50 ° C), three types of thermochromic pigments that reversibly change color, respectively, are added to epoxy resin (including a curing agent. ), The outline pattern 41 of the steam locomotive was punched out and printed by screen printing using the ink dispersed in FIG. In addition, () is the color change point,
It shows that a color is developed below the temperature and the color is erased above the temperature.

When a drink having a temperature of 60 ° C or higher is poured into the cup 1, the outer surface temperature of the cup gradually rises due to heat conduction, and the color of the reversible thermochromic pattern layer 4 becomes purple (raises to 30 ° C to 40 ° C) with the passage of time. When heated, the orange component is in a decolored state), red (the temperature is raised to 40 ° C to 50 ° C, the orange and blue components are in a decolored state), and the non-color-change image 3 is in a concealed state at each stage, Visualize the colored pattern 4 and finally the red color disappears (50 ℃ or more)
Then, the non-color-change image 3 was visualized.

On the other hand, in the process of decreasing the temperature, the opposite aspect to the above was visually observed in stages.

The change in appearance was reversible and was reproduced repeatedly.

Example 2 (illustration omitted) A non-discolored image 3 of Example 1 was printed on the surface of a glass cup 2 and a reversible thermochromic pattern layer 4 similar to that of Example 1 (however, red colorless (20 ° C.), blue colorless). (15 ° C.), a thermochromic pigment that changes color to orange colorless (10 ° C.) was used to form cup 1.

In the normal state (20 ° C. or higher), the cup 1 makes the non-color-changing image 3 visible, but when cold drink is injected, the red and purple patterns 4 are gradually visualized and the non-color-changing image 3 is hidden. None, and finally (below 10 ° C.), the brown pattern 4 was visualized.

The effect of the invention The non-color-changing image and the thermo-chromic pattern are alternately seen by the temperature change, and the multi-colored pattern is visualized in the intermediate state, so that various images of various combinations can be displayed on the limited cup surface. In addition to the subtleties of change, as a decorative cup with a lot of interest, the commercial value of this type of cup can be enhanced in combination with the effect of visually knowing the approximate temperature of the beverage.
