DESCRIPTION OF THE PREFERRED EMBODIMENTS (First Embodiment of the Present Invention) Hereinafter, a compressing material according to a first embodiment of the present invention will be described with reference to FIGS. FIG. 1 is a perspective view of a cold insulator according to the first embodiment of the present invention, and FIG. 2 is an AA enlarged cross-sectional view of the cold insulator.

The cold insulator is deformed into a shape conforming to the uneven shape of the surface of the object to be cooled, and is fixed to the surface of the object to be cooled by a fixing member (not shown) such as a string or a tape. Since the polymer absorber 1a absorbs a smaller amount of liquid than the maximum absorption amount, all the liquid is absorbed inside the polymer absorber 1a, and the state in which the cold insulator is frozen Also, adjacent polymer absorbers 1a are not strongly connected to each other via water. For this reason, the shape of the cold insulator can be freely deformed according to the uneven shape of the surface of the object to be cooled, and the cooling material is brought into contact with the object to be cooled having unevenness such as a nose or an elbow without any gap, thereby cooling the object. The effect can be increased.

Further, since the polymer absorber 1a absorbs a smaller amount of liquid than the maximum absorption amount, the polymer absorber 1a
The dew condensation on the surface of the cold insulator can be absorbed by the polymer absorber 1a. Also, polymer absorber 1
The liquid absorbed by a does not flow out due to the absorbing power of the polymer absorber 1a. Thereby, the object to be cooled and its surroundings can be cooled without getting wet, and the state during cooling can be maintained in a comfortable state. Since the cold insulator is frozen, the cooling temperature can be reduced to -10 ° C or lower, and this temperature can be maintained for 3 hours or longer, and the cooling effect can be enhanced. The temperature can be easily adjusted by wrapping a gauze, cloth, or the like as a cold insulator.

In addition, simply by freezing it in a freezer at home, it has the effect of keeping cool to minus 15 degrees and no dew condensation, and it can be used anywhere and anytime. In addition, since electricity is not required, there is an energy saving effect, and it is economical and convenient because it can be used many times.

As an example of a cold insulator formed by absorbing a liquid such as water into a part of the polymer absorbent body facing one side of the bag, the polymer absorbent body facing the one side of the bag is formed by applying the liquid into a wavy shape or a straight line. A cold insulator having a configuration absorbed along the shape can be formed. Further, the cold insulator can be used even if cooled without freezing.
In addition, a pattern or the like can be applied to the surface of the cold insulator. The weight of the cold insulator can be adjusted by the amount of water absorbed by the polymer absorber 1a. The shape of the cold insulator can be formed as required, such as a rectangular shape or a heart shape. As the liquid, water is used as an example, but a liquid having a low freezing point mixed with a salt or the like may be used.
