DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cold insulator used for keeping cold inside a shipping container.

[0002]

2. Description of the Related Art When delivering various kinds of drinking water to a home, drinking water cooled in a refrigerator in advance is transported in a heat insulating container filled with ice as a cooling body. However, especially in summer, the ice melts quickly and fills the cold storage container, so that the drinking water container gets wet and looks bad. To deal with this problem, we wiped the container of wet drinking water with a cloth, but this was cumbersome, and if a label with the product name was placed on the surface of the container, the label would come off. There was a problem. Further, in a paper container or the like, the paper becomes soggy.

[0003] In order to solve the above-mentioned problem that the water in which the ice is melted is filled in the cold storage container, ice has been packed in a plastic bag, or dry ice has been used as a cooling body instead of ice. However, the work of packing ice in a plastic bag was troublesome, and the plastic bag was damaged, and water in which the ice melted leaked into the cold storage container also occurred. In addition, when dry ice is used instead of ice, the problem of filling the cooling container with water is solved, but it is impossible to recover vaporized gaseous dry ice, so it can be used repeatedly. Cost increased.

[0004] Some cold insulators intended to solve the problems of water leakage and repeated use as described above have been developed so far. For example, Jiko 45-27082
Japanese Patent Application Publication No. JP-A-2005-64139 discloses a cooling body in which a hydrogel formed by adding borax or boric acid to a polyvinyl alcohol aqueous solution is filled in a bag of plastic or the like, or a polyvinyl acetate obtained by dispersing polyvinyl acetate in a polyvinyl alcohol aqueous solution. JP-B-57-28505 discloses that a cold storage device in which a regenerator made of a hydrogel formed by adding borax or boric acid to an emulsion and filled into a plastic bag is disclosed in Japanese Patent Publication No. 57-28505. Storage material consisting of hydrogel obtained by adding a compound having a group,
No. 34 discloses a regenerator consisting of a gel obtained by dissolving a saturated carboxylic acid in a polyacrylic acid aqueous solution, neutralizing and crosslinking with sodium hydroxide and sodium aluminate, and then adding sodium hydrogen carbonate and inorganic salts. Have been.

However, these cold insulators were plastically deformed at temperatures above and below the cold insulator temperature, and could not maintain a constant shape. In other words, the insulated body, which had an irregular shape at a temperature higher than the insulated temperature, is extremely difficult to use because if it is cooled at a temperature lower than the insulated temperature before use, it freezes in its inconstant shape. Had issues.

In addition, ice, dry ice, and the above-mentioned gel-like cold insulator cannot sort and store various kinds of drinking water in a cool container. That is, it is impossible to search for a target product from several kinds of drinking water in a short time, and there is also a problem that work efficiency is poor.

[0007] The present invention has been made in view of the above situation, and is capable of storing various kinds of drinking water separately in a cold storage container, being sanitary and capable of being repeatedly used. The purpose is to obtain.

Embodiment 1 FIG. 1 is a perspective view showing an example of the cool insulator according to the first embodiment. In the drawing, reference numeral 1 denotes a cold storage body, 2 denotes a cold storage body, 3 denotes a cold storage pack, 4 denotes a partition room, 5 denotes a cold storage container main body, 6 denotes a lid, 7 denotes a cold storage container, and 10 denotes a storage item such as drinking water. FIG. 1 (a) shows that a cold insulator 1 using a total of 12 cold accumulators 2 is set in a cold insulator main body 5 so as to form nine partition rooms 4, and each partition room 4 stores drinking water or the like. It shows a state in which the objects 10 are sorted and stored by type. The insulated container body 5 containing the insulated body 1 and the storage items 10 is transported and stored with the lid 6 covered as shown in FIG. 1 (b). The insulated container 7 composed of the insulated container body 5 and the lid 6 is made of, for example, a non-foamable resin having a foamed resin interposed therein as a heat insulating layer (Jpn.
No. 098) or a synthetic resin foam or the like, the size of which is, for example, 340 × 163 × 280 m
m, 400 × 400 × 278 mm, 410 × 203 × 2

There are various sizes such as 5 × 265 mm, 380 × 200 × 260 mm and the like. Products stored in the cool container 7
It is not necessary to limit to drinking water, and foods such as ice cream and yogurt that need to be kept cold may be used.

The regenerator according to the first embodiment is composed of a regenerator 2 shown in FIG. 3, and the regenerator 2 will be described first. FIG. 3 is a front view showing the appearance of the cold storage unit 2, and FIG. 4 is a cross-sectional view showing the internal structure of the cold storage unit 2. The regenerator 2 is formed on a regenerator storage portion 21 for filling the regenerator 8, a flange-shaped fin 22 formed below the regenerator storage portion 21, and on both side ends of the regenerator storage portion 21. It has a flange-shaped side portion 23 and a cold storage agent injection portion 24 formed above the cold storage body 2.

As the regenerator 8, it is preferable to use a purine-like elastic gel composed of a crosslinkable monomer of acrylamide or methacrylamide and having high elasticity at room temperature and high cooling efficiency. Since this purine-like elastic gel can be frozen without being plastically deformed above and below the cold storage temperature as compared with the conventional cold storage agent, the cold storage agent storage portion 21 that fits a given space and fills the elastic gel can be used. It can be formed thin. The elastic gel has a melting temperature of -20.
Because it is possible to control in the range of ℃ ~ 0 ℃
It is possible to produce an elastic gel having a melting temperature that is optimal for proper temperature control of a product. Further, since this purine-like elastic gel is a substance safe for the human body, it is harmless even if it comes into direct contact with food. In addition, as long as the regenerator 8 can be filled in the interior of the regenerator storage unit 21, sodium benzoate is added as an antiseptic to a 4% aqueous solution of sodium carboxymethylcellulose so as to have a concentration of about 0.3%, The above-mentioned conventional regenerator may be used, or only water may be used, but these are inferior to the above-mentioned purine-like elastic gel in terms of cooling efficiency.

The regenerator 2 is a plate-like member made of polyethylene or polypropylene, for example, by a blow molding method disclosed in Japanese Utility Model Publication No. 3-51667.
It has a relatively high strength and has a shape self-holding property. The size of the regenerator 2 is 160 mm in width and 2 mm in height.
Although it is about 50 mm, it can be appropriately determined in consideration of the size of the cold storage container main body 5 and the number of cold storage bodies 2 connected in the width direction thereof. The regenerator storage unit 21
The inside is hollow so that the regenerator 8 can be filled, and its size is about 130 mm in width, 200 mm in height, and about 15 mm in thickness. The fins 22 are for reducing the weight of the regenerator 2 and have a size of about 160 mm in width, 50 mm in height, and about 2 mm in thickness. Each of the left and right side portions 23 has a diameter of 6 mm.
About three holes 26 are provided, and the connecting members 9 for connecting the other regenerators 2 are inserted into the holes 26 respectively. At positions corresponding to the three holes 26, cutouts 27 are formed by tapering the side portions 23 from the outside to the inside. The size of the side portion 23 is 15 mm in width, 200 mm in height, and 2 mm in thickness.
It is about. The three holes 26 are two holes from the top of the cold storage body 2.
They are provided at positions of 5 mm, 110 mm, and 195 mm, respectively. The regenerator injection part 24 is formed in a recess 25 formed in the center of the upper part of the regenerator 2 and has a cylindrical shape with a diameter of about 12 mm and a height of about 14 mm. The size of the recess 25 is 40 m in width.
m and a depth of about 15 mm. The regenerator 8 is filled into the regenerator housing 21 from the regenerator injection part 24, and thereafter the entrance is closed and sealed by a heat seal or the like.

When the above-described regenerator 2 is used, even if a conventional regenerator or water, which undergoes plastic deformation before and after the refrigerating temperature, is used as the regenerator 8, they will remain in the regenerator 21. Since the regenerator 2 is sealed inside, the regenerator 2 can always maintain its plate-like shape, and a state in which the regenerator 2 freezes in an irregular shape is avoided. Further, any type of regenerator may be used as long as it can be sealed in the regenerator storage section 21, so that the applicable range for the regenerator 8 is expanded. Furthermore, it is also possible to form the fins 22 of the regenerator 2 to be longer, cut the fins 22 into appropriate lengths when using them as a cooler, and adjust the height.
