Abstract

PROBLEM TO BE SOLVED: To provide a cold storage agent that is furnished with a temperature monitoring function by color comparison and makes it possible to visually determine, by the color of the cold storage agent, the degree of cold storage in a forcibly cold-storing process in a refrigerator and the remaining cold storing ability while in use, of a common cold storage agent. SOLUTION: Microcapsulated reversibly temperature-indicating organic pigment (2a) is added to a common cold storage agent (1) made of a chemical material as a raw material to obtain the objective cold storage agent (A) with uniformly blended and dispersed components in which the degree of cold storage can be detected by color comparison by utilizing its color developing or color erasing function in the temperature indicating range of the pigment. Alternatively, a common cold storage agent (1) can be uniformly dispersed and blended with the microcapsulated pigment (2a) and a common pigment (3) having a different color. Further alternatively, a common cold storage agent (1) is blended and dispersed with the microcapsulated pigment (2a) and another microcapsulated reversibly temperature-indicating organic pigment (2b) that has a different temperature-indicating range and a different color.

2. Description of the Related Art In the prior art, in the practical use of a regenerator, the regenerator is usually hermetically sealed in a plastic container. Since there is no means for observing the degree of cold storage of the built-in cold storage agent, the cold storage operation is performed at -25 ° C to -3 ° C.
A case or container filled with a cold storage agent is stored in a freezer set at a constant temperature of 5 ° C, and used for a long time of 10 to 13 hours to ensure cold storage, and then used for qualitative judgment and then released. It is customary. This is because a means for measuring the temperature of the regenerator filled in the case or the container has not yet been established. Therefore, a method of observing the cool storage effect by attaching a seal coated with a temperature pigment ink that develops a color below the set temperature and erases the color above the set temperature was attached to the case or the surface of the container. ° C to -35 ° C
Because the temperature is set to a very low temperature, even when the temperature storage sticker attached to the surface is unable to store the cold storage agent filled in the case or container, the seal touching the temperature inside the freezer responds, as if It shows color as if it had been sufficiently stored cold, but when it comes out of the freezer and the temperature indicating sticker touches the outside air, the color immediately disappears, and it turns out that the filled cold storage agent is not sufficiently stored cold and it can not be used practically And the like. Further, there is no criterion for determining the degree of remaining cold storage during use of the cold storage agent that has been reliably stored, and there is a problem that it is difficult to determine when to replace the cold storage agent.

(C) In the above-mentioned method, the color disappears when the regenerative effect is lost, but it is inconspicuous, so that it is used in combination with the organic reversible thermochromic pigment (2a) to reduce the temperature to a color different from that of the organic reversible thermochromic pigment. The non-sensitive ordinary pigment (3) is added to the ordinary regenerator (1) to form a homogeneous regenerator. (D) In order to know the remaining cold storage degree when using the cold storage agent, an organic reversible thermochromic pigment (2

[Action] The action of the above item (b) is a measure for confirming the ultimate cold storage effect in the cold storage step of the cold storage agent (1).
When the temperature is lower than the set temperature range of the organic reversible thermochromic pigment (2a), the color develops, and when the temperature exceeds the temperature range, the color of the organic reversible thermochromic pigment disappears. The function of the above item (c) has the same purpose as that of the above item (b), but the organic reversible thermochromic pigment (2)
Below the set temperature range of a), the organic reversible thermochromic pigment develops a color and conceals another pigment (3) of another color. Disappears, and the color of the pigment (3) usually develops independently. The effect of the preceding paragraph (d) is different from (b) and (c),
Below the temperature range of the organic reversible thermochromic pigment (2a), which was used as a guide for confirming the extreme cold storage effect, the color was formed simultaneously with the separately added organic reversible thermochromic pigment (2b),
The color of the organic reversible thermochromic pigment (2a) masks the color of the organic reversible thermochromic pigment (2b). When the temperature of the organic reversible thermochromic pigment (2a) becomes higher than the temperature range of the organic reversible thermochromic pigment (2a), the color of the organic reversible thermochromic pigment disappears, and the color of the concealed organic reversible thermochromic pigment (2b) alone becomes visible. I do. Furthermore, when the cold storage temperature rises above the temperature range of the organic reversible thermochromic pigment (2b), the color of the organic reversible thermochromic pigment also disappears,
It has the function of exhibiting an achromatic color of the regenerator (1). Since each of (b), (c), and (d) above uses a reversible thermochromic pigment, the coloring, decoloring, or discoloring is repeated many times depending on the temperature in the temperature range. Hold.

According to the present invention, the container (4) is sealed and filled.
The regenerator capable of sensing the degree of regenerative storage by colorimetry has the effect of directly informing the temperature of the regenerator itself by color in the forced regenerative storage process in the freezer, without being affected by outside air around the surface of the container (4). Therefore, in the cold storage process, the cold storage agent containers are collectively housed in a freezer as in the conventional case, and the effect of eliminating the troublesomeness such as not being able to guarantee the cold storage effect unless it is stored for a long time until it becomes supercooled is effective. can get. This is because the use of the cold storage agent of the present invention, which can detect the cold storage temperature by colorimetry, can improve the inefficiency due to the qualitative determination of the cold storage effect due to supercooling. For example, even if the container (4) filled with the cool storage agent is not stored in the freezer at a time, it is possible to separate the containers by the color for notifying that the cool storage is performed. Further, even when the cool storage agent is used, there is an effect that the remaining cool storage ability can be determined by disappearing or discoloring the color.
