The cube preferably has a spherical or nearly spherical form to prevent the damage to the cooling object in the case of wrapping with the net.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cold insulator which can easily cool or hold an article at a low temperature and can be used repeatedly in a sanitary manner.

[0002]

Heretofore, as a simple cooling and low-temperature keeping method, a technique using a cooling material in which a solvent is sealed in a small container has been adopted. In particular, in recent years, a cold insulator having improved sanitary properties, which can be repeatedly used for foods and the like, has been widely adopted. In fact, the applicant of the present application discloses a cold insulator in which a salt water or alcohol solution for suppressing the growth of bacteria and the like is sealed in an antibacterial kneading resin container (Japanese Patent Application No. 9-172937). These cold insulators are frozen in advance and put in a heat insulating case such as a foamed resin together with the article to be cooled and used.

[0003] By the way, as for the size of the cold insulator, the same size as the ice for beverages is widely adopted because of the ease of freezing and the size of the article to be cooled and the size of the case. For this reason, usually, it is necessary to use several tens or more cold insulators for one case, and the cold insulator is scattered in the case. In particular, when the object to be kept cool is small, the article gets into the cold insulator and it takes time to take it out.
As a result, the working efficiency is significantly lacking. Of course, this problem can be solved by increasing the size of the cooling material itself. However, from the viewpoint of the cooling effect, it can be said that it is preferable that the material is in close contact with the article, that is, the same as or smaller than the article to be cooled. In addition, there is a problem that the larger the heat insulating material, the more difficult it is to put in a case.

[0004] The present invention has solved the above-mentioned problems of the conventional cold insulator, and has the following advantages.
The present invention discloses a technique relating to a new hygienic heat insulating material which is effective in terms of adhesion to articles and work efficiency, and which can be used when transporting food in summer.

[0005]

In order to achieve the above-mentioned object, the present invention employs means for grouping cubes in which a refrigerant is sealed in an antibacterial agent-mixed resin container. When such a means is employed, even if a cold insulator having a size approximately equal to that of a conventional cold insulator is used for each cube, the cold insulator and the article can be easily separated without being mixed.

More specifically, a means is adopted in which the cubes are surrounded by a net made of a resin kneaded with an antibacterial agent to form a group. Since the net itself has antibacterial properties, bacteria and the like hardly adhere thereto. Further, a means for dividing a group surrounded by the net into a plurality of small groups so as not to bias the cube in the net is also employed. By employing such means, the cube can be evenly brought into contact with the article.

Further, in order to cover the surface of an article in a box or the like, or to wrap the entire article, a means is adopted in which cubes are provided on a flexible flat plate surface made of a resin mixed with an antibacterial agent to form a group.

On the other hand, since the whole group of the cubes does not necessarily come in contact with the article, means for covering a part with a heat insulating material is employed. When such a means is adopted, it is possible to block heat from the outside when covering or wrapping the cooling material on the article, and the cooling effect is maintained for a long time.

[0009]

Preferred embodiments of the present invention will be described below with reference to the accompanying drawings. FIG. 1 shows an example in which the cold insulator employed in the present invention is actually used for an article. A characteristic configuration of the present invention is that a group of cubes 1 in which a refrigerant is sealed in an antimicrobial-kneaded resin container is a group, and the cubes are the same as the conventional cold insulator disclosed by the applicant of the present application and the size thereof. The pod materials are not particularly unchanged. In other words, it is easy to cool the conventional cold insulator, and has the same adhesion to the cold insulator as it is, and further avoids the problem of scattering of the cold insulator in the case and separation from the article, which were problems. is there. In addition, since the present invention employs an antibacterial agent kneading resin also as a member for grouping the cubes 1, it is sanitary and can be sufficiently used for food. There are various methods for grouping the cubes, and examples thereof will be described below.

FIG. 2 shows a first embodiment of the present invention, in which a net-shaped bag 2 made of an antibacterial agent kneading resin is used.
And Cube 1 in it. The characteristic configuration of the present embodiment is that the cubes are grouped by a net-shaped bag made of an antibacterial agent-mixed resin, and the cubes are not scattered in the case. Furthermore, since the entire net can be washed, even if it becomes dirty during use, processing such as sterilization and cleaning can be easily performed.

The mesh of the net may be any size as long as the cube does not protrude, but it is better to be fine if an article gets into the net. Conversely, the cube can be made fine as long as it does not protrude from the net, and a cube that matches the shape of the article can be employed.
It is preferable that the amount of cubes in the net has a sufficient density so that the cubes can be appropriately moved in the net. Further, if the net can be freely opened and closed with a string or a fastener, the user can determine a necessary amount of cubes, which is more convenient. Also,
When the cubes are biased, it is preferable to use one net 2 divided into a plurality of small groups as shown in FIG. As a dividing method, a technique of connecting a plurality of nets of the same size, or using a non-net film or the like may be used. Further, after the user puts the cube 1 into the net 2 composed of one area as shown in FIG. 2, it is possible to tie a suitable position of the net at several places with a string or the like. The cubes and nets used in the present invention are:
Since the function does not change in particular, common reference numerals are used in the drawings showing the embodiments.

FIG. 3 shows another embodiment of the present invention, in which a cube 1 is provided on one surface of a flexible flat plate surface 3 made of a resin kneaded with an antibacterial agent. The characteristic configuration of the present embodiment is that a cube is provided on one side of the flexible flat plate, which is particularly effective when wrapping or covering an article. Of course, in the case of being used between articles, it is preferable to provide cubes on both sides. In FIG. 3, the cube 1 is directly attached to the flexible flat plate 3. However, the shape is not limited as long as it is grouped by a sheet. The ones shown are applicable.

FIG. 4 (a) shows a group in which a net made of an antibacterial agent-mixed resin is provided on a flexible flat plate surface 3, and a cube 1 is put in a region between the net and the sheet. Further, in this embodiment, the cube is not biased,
It is divided into multiple spaces. On the other hand, FIG. 4 (b) shows that a presser 4 is provided on a pair of opposite sides of the flexible flat plate surface 3. Then, a thin and elongated cube is attached to the surface in such a manner that both ends of the cube are hooked on the holder. Further, such a flexible flat plate can be easily wound along the longitudinal direction of the cube, as shown in the figure, and is convenient for portable use. The flexible flat plate used in the present invention is a flat plate made of a resin mixed with an antibacterial agent and capable of deforming the flat plate to a certain extent such as bending or winding. Therefore, the flexibility of the flat plate is preferably appropriately selected as necessary.Specifically, when wrapping, a foldable one is used, and when covering the top, a firm one is used instead of the lid. It is good to adopt each.

FIG. 5 shows an embodiment in which the cubes 1 are connected with a thin antibacterial agent kneading resin. FIG. 5A shows a group in which rings are provided so as to protrude from the cube, and the rings are passed through a thread-shaped antibacterial agent kneading resin to form a group. Even if such a cold insulator is mixed with an article, it can be easily separated by pulling up a part of the yarn.
For example, it is particularly effective when a large number of small articles are kept cool in one case. Further, as shown in FIG. 5B, the cubes 1 may be connected in such a manner that a part of each cube 1 is extended. This embodiment is suitable for use on the bottom surface of a heat-resistant case.

By the way, it is not preferable in terms of energy efficiency if a part of the group of cubes that does not come into contact with the article is left as it is. Therefore, in the present invention, a heat insulating material is provided in such a portion. For example, a heat insulating material may be provided on one side of the above-described flexible flat plate, and the heat may be shielded from outside by covering or wrapping the article so that the portion provided with the heat insulating material is on the outside. . When such a heat insulating material is employed, the cooling effect can be maintained for a longer time. Also, the net-shaped bag as shown in FIG. 1 is not in contact with the product, that is, by covering half of the upper bag with heat insulating material, it is possible to keep the low temperature even without the lid. Will be possible.

The cube is preferably one in which a soluble salt water or alcohol is sealed as a refrigerant in the antibacterial agent-mixed resin container already disclosed by the present inventors. In addition, the shape is a shape without corners from the viewpoint of not damaging the article when it is put together with a net-like object.
A sphere or a shape close to the sphere is preferable, but the shape can be appropriately set as needed. For example, a rectangular parallelepiped, a tetrahedron, a cylinder, or the like may also be used as a non-slip product. Moreover, when adopting it for a sheet-like thing, a thin thing is preferable in consideration of the case where a product is wrapped. Specifically, a disk shape, a thin rectangular parallelepiped, a shape of a go stone, and the like are applied. However, too thin cubes have a problem in the persistence of the cooling effect, so that it is necessary to appropriately select them according to the application. In particular, when used over an article, the size of ice for beverages may be preferable.

[0017]

According to the present invention, the conventional cube-shaped cold insulators are grouped together, thereby avoiding the problem of scattering of a large number of cubes and improving the working efficiency. In particular, even when the object to be cooled is small, the two can be easily separated without being sunk into the heat insulating material. In addition, it has become possible to adopt a cube that matches the size and shape of the article to be kept cool. In addition, it has become possible to cover or wrap the article by gathering it on a flexible flat plate surface. Furthermore, by adopting a heat-insulating material for a part of the group of cubes, the penetration of heat from the outside was prevented and the thermal efficiency was improved.

On the other hand, since the cubes are made of a group of resin mixed with an antibacterial agent, all of the surface of the heat insulating material has an antibacterial effect and can be used hygienically for foods and the like.
