[0006]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, the present invention will be described in detail.
The “cold storage container” has a flat outer shape. The planar shape is not particularly limited, and may be any of a rectangle, a square, a circle, an ellipse, and the like, but a rectangle having a slightly rounded corner is particularly preferable. The method for forming the cool storage agent container is not particularly limited, and can be formed by an appropriate method such as blow molding, injection molding, or compression molding. As the molding method, a blow molding method capable of easily molding the hollow container is preferable. Although the kind of this resin is not specifically limited, General purpose resin, such as polyolefin, such as high density polyethylene, low density polyethylene, a polypropylene, polyamide, and polyester, can be used. In particular, a polyolefin having excellent low temperature brittleness and sufficient water resistance and chemical resistance is preferred. Further, high-density polyethylene that is easy to mold and has high strength is more preferable.
[0007]
In the cool storage agent container unit, the side ends of the plurality of cool storage agent containers and the recesses of the fixture are fitted together, and the respective cool storage agent containers are held together. The structure or the like of the fixture is not particularly limited as long as each cool storage agent container is held without dropping during handling such as when the unit is placed on a CRB or the like. Furthermore, although the material of the fixture is not particularly limited, various resins used for manufacturing the cold storage agent container can be used. Also, the method for forming the fixture is not particularly limited, but the fixture is preferably solid because it requires sufficient strength, and is preferably molded by an injection molding method or the like.
[0008]
In general, the regenerator stored in the regenerator container is preferably one that freezes in a short time, requires less energy for freezing, and has a long effective cool keeping time. Practically, water having a large latent heat of fusion is used as a main ingredient, and a gelling agent, a cryogen and the like are blended therein. As the gelling agent, a highly water-absorbing polymer that is made water-insoluble by crosslinking a hydrophilic polymer such as carboxymethyl cellulose, polyvinyl alcohol, sodium polyacrylate, polyacrylamide or the like can be used. Natural polysaccharides such as starch, gelatin and guar gum can also be used. The gelling agent is usually blended in an amount of 1 to 5 parts by mass, particularly 1 to 3 parts by mass when the regenerator is 100 parts by mass. Since the viscosity of the regenerator decreases as the blending amount of the gelling agent decreases, it becomes easier to work when filling the container with the regenerator, so it is preferable not to add the gelling agent beyond the required amount.
[0009]
Examples of the cryogen include metal salts of inorganic acids such as sodium chloride and potassium chloride, and polyhydric alcohols such as ethylene glycol and propylene glycol. These cryogens should just mix | blend a required quantity with water according to the desired melting | fusing point of a cool storage agent. Furthermore, when the regenerator is supercooled, it takes a long time for freezing and a great deal of energy is required, so a nucleating agent is often blended so that it freezes quickly near the melting point. This nucleating agent becomes an ice crystal nucleus for freezing of the regenerator, and as the nucleating agent, an inorganic compound such as silver iodide and an organic compound such as metaldehyde, α-phenazine, and steroid are used. Can do. In addition to the regenerator, additives that are usually used for this type of regenerator such as preservatives, antifungal agents, and colored powders can be blended as needed, as long as the characteristics are not impaired.

It can be mounted on. When placed in such a direction, the cool air is sufficiently lowered from the space between the respective cool storage agent containers 1 and can be efficiently kept cool. Moreover, even if each gripping part 13 of each cool storage agent container 1 is fixed so that each gripping part of the adjacent cool storage agent containers 1 faces each other, it protrudes to the extent that they do not come into contact with each other. When forming a unit using the cool storage agent container 1, it is not necessary to give special consideration to the surfaces of the adjacent cool storage agent containers 1 that face each other. Furthermore, the four cold storage agent containers 1 can be more firmly and integrally fixed by fitting the locking portion 2121 and the locking recess 1121 to each other.
[0019]
The present invention is not limited to the specific examples described above, and can be variously modified examples within the scope of the present invention depending on the purpose and application. For example, the planar shape of the convex portion 14 provided on the surface of the container base 11 is not limited to a circle, and may be any shape such as an ellipse, a triangle, a square, a rectangle, and the like. Moreover, the height of the convex part 14 is not specifically limited, It can set suitably with the magnitude | size of the cool storage agent container 1, and the space required between each container. However, the upper end surface of the convex part 14 needs to be formed flat so that the adjacent cool storage agent containers 1 may not slide easily. Moreover, it replaces with the convex part 14, forms a convex part on the one surface of the container base | substrate 11, and the recessed part which can be fitted with this convex part on the other surface, and makes this convex part and a concave part fit, and it is plural. These regenerator containers 1 can also be used in an integrated manner.
[0020]
Furthermore, in the cool storage agent container unit 2 in which the plurality of cool storage agent containers 1 are integrally fixed by the fixture 21, the cool storage agent is frozen while being stored in this freezer, but the unit is transported to the freezer. Often done manually. At this time, the size and weight of the unit are usually such that one unit can be carried with one hand, although it depends on the size of each regenerator container forming the unit. Therefore, even if it is carried with both hands, one worker can carry only two units at a time. However, in order to carry this unit more efficiently, the unit as shown in FIGS. It is also possible to hang the string 3 around the appropriate place and carry the two cold storage agent container units with one hand by holding the string 3. For example, when twelve cool storage agent container units are transported to the freezer, when one worker carries two units at one time, they must be transported six times to the freezer, but four at a time. When an individual unit is carried, the number of times of transportation is three times, and the work efficiency at the site can be greatly improved.
