Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to clay whose color changes when mixed with natural liquid.

Traditionally, for example, clay that is often used as children's toys is sold as colored clay that has been colored in a specific color, but such colored clay adheres to the principle of the three attributes of color by mixing them. All it can do is follow the color change, and it lacks surprise and interest.

Therefore, the present invention provides a color-changing clay containing a color-changing agent that can change color due to a change in P, such as a pH finger indicating sound. It is necessary to consider interest and interest, and from this point of view, the object is to provide a clay that is familiar to daily life and highly safe, and whose color changes when mixed with a natural liquid.

The clay used in the present invention is grain clay, such as wheat flour clay based on wheat flour, sticky rice flour or rice flour clay based on rice flour, corn flour clay made from potato clay and corn flour, etc., in terms of colorability and plasticity. It is preferably used from In addition, mineral clays, which are aggregates of fine hydrated silicates that exhibit plasticity when mixed with an appropriate amount of water, such as kaolin clay, bentonite clay, and kibushi clay, can also be used.Furthermore, bacterial molecular clays, such as rubber clays, can also be used. All kinds of clay such as clay, paper clay, oil clay, etc. can be used.

One of the color-changing agents used in the present invention is a so-called P H, 1M indicator that changes color or disappears depending on changes in the PIt range. Table 1 shows typical PH indicator color change pTl regions, acidic colors, and basic colors. For example, to color grain clay from colorless to yellow, m-=trophenol may be used, and to color it purple-red, phenolphthalene may be used. It should be noted that it is better to use only 11 types of color changing agents, but by mixing two types of color changing agents with different color change P ■■ areas, it is possible to obtain color changes of several types according to changes in pH. can.

'-AT'''Blank Table 1 Also, as an example of a color change agent]) There are color change pigments that change color depending on fluctuations in the color change agent. Shown in Table 2.

In Table 2, for example, the Berri 1 class pigment is red at pH 3;
I) H4-6 shows a reddish-purple color, i) HB shows a dark blue color.

These color-changing pigments are particularly preferably water-soluble in order to uniformly and effectively color the clay. When using natural pigments, not only isolated natural pigments but also those containing other impurities can be used.

Historically, additives that are commonly used from the viewpoints of light-blocking properties, antioxidant properties, heat resistance, etc. can be used as the above-mentioned color-changing dyes.

Other examples of color changing agents include acid violet 6B,
Pigments used as edible coloring agents such as Orange ■, Black PN, and Green S may also be used.

In the present invention, in order to cause a color change in the clay by mixing it with the clay containing the color change agent, a natural liquid, seasoning, or soft drink having a certain pH is mixed alone into the clay, or Mix the natural product liquid etc. into other clay in advance,
Clays are kneaded together to achieve desired PHKA adjustment and color change. Here, the natural liquid juice is, for example, fruit juice such as mandarin orange, tomato, lemon, etc., or vegetable juice such as cucumber, radish, etc. Also, seasonings include soy sauce, bonic acid, Ajinomoto (registered trademark,
Ingredients are sodium glutamate), and soft drinks include soda water and the like. Table 8 lists the pH values of main natural juices.

In addition, when a color-changing dye is used as the color-changing agent, there is a color-changing dye that changes color with a specific metal ion or solvent, and when this color-changing agent is used in combination, even more diverse color changes are possible. For example, hibiscus pigment is an orange-red color due to trivalent ions.
The color changes to purple due to divalent tin ions.

Shikonin turns dark green in ferric chloride solution and purple in copper sulfate solution.

Next, to collect the natural product juice from fruits, vegetables, etc., the fruit or vegetable can be put into a juice squeezer ( ) shown in FIG. 1, for example, to obtain the liquid juice.

In other words, the squeezer (1) consists of the container body (2) and the top lid (3).
The container body (2) is equipped with three legs (4) and a juice dripping opening (5) at the lower end, and inside there are many protrusions that hold the fruit and the liquid juice. It has a built-in substrate (8) provided with a lower hole. Furthermore, the upper lid (3rV) is screwed with a shaft (8) that moves the upper disk (7) downward by -F by rotation of the handle (0).Therefore, in order to collect the liquid juice from fruits, etc., the above-mentioned container Put fruit, etc. inside the main body (2), fit the top lid (2), and push the upper disk (7) by 1 to 100 degrees by rotating the handle, and then break the fruit, etc. 81 between it and the base plate (8). Drop the obtained juice through the filter 1
．． :] Taken from (f)). Note that the sap squeezer is not limited to the one mentioned above, and various types can be used, but for example, as shown in Figure 2, it is also possible to use a radish grater that is commonly used in the past, and a strainer with a filter cloth. can be used to collect sap.

Therefore, in the present invention, clay (In) containing various discolorants shown in FIG. 8, and a sap squeezer (1) shown in FIG.
or the clay OQ and the strainer shown in FIG.
When combined with the source cloth (not shown) as a set, it can become a valuable product as a children's toy or teaching material.

In order to make the discoloration phenomenon caused by the mixing of natural product sap more vivid and to prevent color fading, polyhydric alcohols, e.g. It is preferable to mix ethylene glycol, propylene glycol, chrycerin, polyethylene glycol, pentaerythritol, etc. with calcium chloride, or to add each separately.

The polyhydric alcohol is added in an amount of 5 to 60 parts, preferably 15 to 85 parts, per 100 parts of natural sap or clay. Calcium chloride is 0.1 to 5 parts, preferably 0.5 to 5 parts.
2.0 parts are added.

In addition, when grain powder clay is used as the clay, additives that have been commonly used in the past, such as anti-warming agents, thickeners, anti-drying agents, and lubricants, can be used.

As mentioned above, the color-changing clay of the present invention can be colored in a variety of ways using safe ingredients such as fruit juice that are familiar to daily life, and therefore it can be said to arouse children's interest and is extremely suitable as a toy and teaching material for children. .

The present invention will be described below with reference to Examples, but the present invention is not limited to these Examples.

Example 1 A flour clay with the following composition was prepared.

Flour 45 parts water
40 parts ethylene glycol 10 parts Sunwet 3 parts Bromocresol Clean 20 parts The pH of the above composition is about 5.4. By mixing an appropriate amount of lemon juice with this composition, the clay changes color from green to yellow. When an appropriate amount of 4-furi liquid was mixed into this, it turned yellow.

Example 2 In Example 1, methyl red is mixed in instead of Promkrezur green. When lemon juice was mixed in, the composition changed from reddish brown to red, and when cucumber juice was mixed in, it turned yellow.

Example 8 A flour clay with the following composition was prepared.

Wheat flour 45 parts Water 40 parts Ethylene glycol 1 part Salad oil 5 parts Hibiscus pigment 8 parts When an appropriate amount of lemon juice was mixed into this composition, the color changed to orange, and as the amount of mixture was increased, the color changed to bright red.
