[0004]

SUMMARY OF THE INVENTION The present invention comprises a reversible thermochromic toy element and a discoloration medium container for accommodating a cooling or heating medium, and discharges and discharges the toy element or the cooling or heating medium. Alternatively, a discolored toy set configured to contact the two and to discolor the toy element by being dropped is required. Further, a configuration in which the discoloration medium container is disassembled or the outer shape is deformed to allow the cold or heating medium to flow out and come into contact with the reversible thermochromic toy element, and the discoloration medium container has a hollow portion inside by fitting. A container that forms a container, and stores the cold or hot medium therein by fitting the container, and the shape of the discoloring medium container imitates food, and the reversible thermal discoloration. The shape of the sex toy element imitates food or tableware, the reversible thermochromic toy element is provided with a cover covering the lower surface, and a hole communicating with the cover at at least one location on the bottom surface of the molded product. The reversible thermochromic toy element is contained in a container, and the disassembly or opening of the container causes the toy element to be released into the discoloring medium container and discolored. And

[0005] The structure of the discoloring medium container for containing a cooling or heating medium therein is, in a system for disassembling or deforming the container, made of a water-containing material such as a sponge or a material such as water in advance. After heating or cooling the discoloring medium container containing the medium, it is configured to be destroyed, or has a hollow portion inside, and the hollow portion is configured to be filled with hot water or cold water and can be stored therein, when necessary. What is released by squeezing or decomposing, the outer surface is formed of a flexible member, a sponge is built in, and the flexible member is squeezed when necessary to release the medium impregnated in the sponge. And the like. Sponge, rubber, and plastic are preferably used as the material of the discoloring medium container. Examples of the shape of the discoloration medium container include a shape imitating an egg, a shape imitating fruits such as apples and grapes, and a shape imitating vegetables such as tomatoes and carrots.

In the system in which the discoloring medium container is located below, a sponge for absorbing a cold or heating medium is provided inside the sponge for contacting the reversible thermochromic toy element falling from above and discoloring the toy element. A structure in which a toy element comes into contact with the sponge,
An example of the container includes a container that accommodates a metal plate through which heat of a medium is easily transmitted, and a toy element contacts the metal plate. Examples of the shape of the discoloring medium container include a shape imitating tableware, a cooking machine, and the like.

As the reversible thermochromic toy element, a molded article formed of a material such as rubber or plastic is suitably used, and a material which reversibly changes color due to a temperature change is blended or molded in the molded article. It is obtained by applying an ink containing the reversibly discoloring material to a body surface. Examples of the shape of the molded product include dishes such as plates and cups, seasoning containers, cookers such as mixers, pots and frying pans, and simulated foods such as fried eggs, and the shape is not particularly limited.

The reversible thermochromic material used for discoloring the reversible thermochromic toy element is an organic compound medium which reversibly causes a color reaction between an electron-donating color-forming organic compound and an electron-accepting compound. The thermochromic material containing the three components is preferably used. Specifically, Japanese Patent Publication No. 51-3541
No. 4, Japanese Patent Publication No. 51-44706, Japanese Patent Publication No.
The thermochromic materials described in JP-A-17154 and JP-A-7-186546 are exemplified. Further, as described in Japanese Patent Publication No. 29398/1992 proposed by the present applicant, a thermosensitive material having high sensitivity having a hysteresis width of 3 ° C. or less with respect to a color density-temperature curve due to a temperature change can be mentioned. The color changes before and after a predetermined temperature (discoloration point) as a boundary, and only one specific state can exist in a normal temperature range between the two states before and after the change. That is, the other state is maintained while the heat or cold required for the state to develop is applied, but returns to the state exhibited in the normal temperature range if the application of the heat or cold disappears, so-called, A small hysteresis width (Δ
H) is a type that changes color.

Also, Japanese Patent Publication No. 4-171 proposed by the present applicant.
No. 54, a thermochromic color-memorizing thermochromic material exhibiting large hysteresis characteristics and discoloring.
That is, the shape of the curve plotting the change in the coloring density due to the temperature change is large in the case where the temperature is increased from a temperature lower than the discoloration temperature range and conversely when the temperature is decreased from the temperature higher than the discoloration temperature. A type of discoloring material that discolors by following different paths, in a normal temperature range between a low-temperature side discoloration point and a high-temperature side discoloration point, in a state changed at a temperature equal to or lower than the low-temperature side discoloration point or higher than the high-temperature side discoloration point. A thermochromic material having a feature capable of retaining and storing data is also effective.

[0010] Further, a homogeneously compatible solution of an electron-donating color-forming organic compound, a compound having a phenolic hydroxyl group, and a reaction medium for determining the temperature at which the color-reaction of both of them occurs is made of a vinyl chloride-vinyl acetate copolymer resin. The thermochromic material described in JP-A-6-135144, which is obtained by dispersing the thermochromic material in fine particles, is also effective.

Although the above-mentioned reversible thermochromic material is effective even when applied as it is, it is preferable to use it by encapsulating it in microcapsules. This is because the reversible thermochromic materials are maintained at the same composition under various conditions of use and can exhibit the same effects. By being encapsulated in the microcapsules, a chemically and physically stable pigment can be formed, and the particle diameter is 0.1 to 100 μm, preferably 3 to 3 μm.
The range of 0 μm satisfies the practicality. The microencapsulation is performed by a conventionally known interfacial polymerization method, in situ polymerization method, in-liquid curing coating method, phase separation method from an aqueous solution, phase separation method from an organic solvent, a melting dispersion cooling method, an air suspension. There are a coating method, a spray drying method, and the like, which are appropriately selected according to the application. Further, a secondary resin film may be further provided on the surface of the microcapsules according to the purpose to impart durability or to modify the surface characteristics for practical use.

As a molded product obtained by blending the above-described reversible thermochromic material with a molding material, for example, a white plastic resin blended with a reversible thermochromic material that changes color from white to yellow due to a temperature change is molded. Fried egg obtained by bonding the yolk to a white body obtained by molding a white plastic resin, by dropping hot or cold water, the reversible thermochromic material develops color, as if a fried egg was completed. Can give an appearance. The molded product may be a blend of a plurality of types of reversible thermochromic materials having different colors and discoloration temperatures.

In the case where a reversible thermochromic layer is formed on the surface of a molded article by using a thermochromic ink in which the reversible thermochromic material is dispersed in a medium containing a fixing agent, the reversible thermochromic material is contained in the medium. 0.5 to 40% by weight, preferably 1 to 30%
% By weight. If the amount is less than 0.5% by weight, a clear thermochromic effect is hard to be visually recognized, and if it exceeds 40% by weight, the color is excessive and may be in a decolored state to cause a residual color.

The reversible thermochromic layer can be formed by a conventionally known method, for example, printing means such as screen printing, offset printing, gravure printing, coater, tampo printing, transfer, brush coating, spray coating, electrostatic coating, electroforming. It can be formed on the surface of the simulated food by means such as coating, flow coating, roller coating, and dip coating.

The color change of the thermochromic layer can be varied by mixing an appropriate amount of the non-thermochromic colored dye in the reversible thermochromic layer. Further, an image such as a pattern may be arranged below the reversible thermochromic layer by the non-thermochromic colored dye and the image may be hidden.

The thickness of the reversible thermochromic layer is 5 to 20.
When the thickness is 0 μm, preferably 10 to 50 μm, the above-described thermochromic effect is sufficiently performed. When the thickness exceeds 200 μm, the degree of freedom in setting the discoloration temperature is lacking in terms of heat conductivity, and the durability of repeated use of the layer having a thickness of 5 μm or less is difficult to satisfy.

The reversible thermochromic layer may be formed by laminating two or more layers, and each layer may be a layer whose color is changed at the same temperature or a layer whose color is different from each other.

In the above-mentioned structure of the molded product, a light stabilizer is added to a molding material forming the molded product, or a reversible thermochromic layer provided on the surface of the molded product, or a light stabilizer layer is provided thereon. Can also. Specifically, the light stabilizer layer is selected from an ultraviolet absorber, an antioxidant, an antioxidant, a singlet oxygen quencher, a superoxide anion quencher, an ozone quencher, a visible light absorber, and an infrared absorber. This is a layer in which the light stabilizer is fixed in a dispersed state. Furthermore, functions such as durability can be improved by adding an antioxidant, an antistatic agent, a polarity imparting agent, a thixotropic agent, an antifoaming agent and the like as necessary.
