Description

[Detailed explanation of the idea]

"Field of Industrial Application" The present invention relates to a box for transporting live fish, etc., and more specifically, to a box for transporting live fish, etc. that is inexpensive, does not collapse, has a long cooling time, and can be transported by truck. ``Conventional technology'' ``Problems that the invention aims to solve'' Conventionally, live fish were transported by placing water and live fish in a gas-barrier polyvinylidene chloride bag, sealing in oxygen, and storing it in a cardboard box. A method of transportation is being adopted. However, when such a method is used, the strength of the cardboard box decreases due to internal moisture, and the cargo collapses when stacked during transportation or storage.Vinylidene chloride is expensive. Since there is almost no cooling effect, it is practically impossible to replenish oxygen from outside the cardboard box, even though live fish consumes a large amount of oxygen, so we have no choice but to rely on air transportation, which can be transported in a short time. . Therefore, there are drawbacks such as increased transportation costs. "Means for Solving the Problems" In view of the above-mentioned circumstances, the present invention provides a box for transporting live fish, etc., which eliminates these drawbacks. That is, the present invention is composed of a lid body and a container made of foamed synthetic resin, and the container accommodates water and live fish through a non-porous partition made of foamed synthetic resin with a thickness that can control the movement of cold air to the required amount. A live fish storage room,
The contents are a box for transporting live fish, etc., which is divided into a refrigerant storage chamber containing water and a refrigerant. DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be explained based on the drawings, in which FIG. 1 is a longitudinal sectional view and FIG. 2 is a horizontal sectional view. In these figures, the box for transporting live fish, etc. of the present invention consists of lids 1 and 2 made of foamed synthetic resin, and the container 2 has non-porous partition walls 3, 3 to accommodate live fish, etc., for storing water and live fish 4. It is divided into chambers 5, 5 and a refrigerant storage chamber 7 for accommodating a refrigerant 6. Concave air gun insertion ports 8, 8 are provided in the upper lid 1 of the live fish storage chambers 5, 5. An air gun is inserted into the insertion ports 8, 8, the thin walls of the insertion ports are destroyed by the pressure of oxygen, and the interior of the live fish storage chambers 8, 8 is filled with oxygen, and then sealed with a tape seal or the like. FIG. 3 shows still another embodiment, in which a refrigerant storage chamber 7 is provided in the center, and live fish storage chambers 5 are provided around it.
is installed. With this structure, since the non-porous partition wall 3 is in 100% contact with the live fish storage chamber 5, the cold air in the refrigerant storage chamber 7 is most effectively transmitted to the live fish storage chamber 5, and the temperature is maintained within the desired temperature range for a long time. can do. The transport box of the present invention is made of a foamed synthetic resin such as foamed polystyrene or foamed polyethylene, but foamed polystyrene is particularly suitable as it has appropriate rigidity as a box and has excellent heat insulation properties. It is also a preferred embodiment that the non-porous partition wall 3 of the present invention is composed of a thin wall portion and a thick wall portion in order to enhance the heat transfer effect. That is, the former is mainly for exchanging heat between the refrigerant storage chamber 7 and the live fish storage chamber 5,
The latter is mainly intended to provide sufficient strength as a partition wall to isolate both chambers.
The thickness of the non-porous partition wall 3 or the thickness of the thin and thick portions is determined by comprehensively considering the size of the container, water temperature, type of live fish, transportation time, etc. For example, the shape shown in FIGS. 4 and 5,
Using a shipping box of the same size, the amount of water is 20, and the outside temperature is 30℃.
Assuming that the amount of ice used is 1.5 kg, the refrigerant storage chamber will contain only ice blocks and water at 0 to 20 degrees Celsius, which is the survival range for live fish.
The thickness of the non-porous septum required to hold for ~30 hours was tested. The results are shown in Table 1. The initial water temperature was 10°C, and the temperatures in the table indicate the lowest temperatures reached.

[Table] From Table 1, in the case of only ice blocks, the heat transfer area is smaller than that of ice water, and as a result, the lowest temperature reached is also slightly higher than that of ice water. From the above, it is understood that the temperature can be controlled within the survival range of fish by selecting ice blocks, ice water, or other suitable refrigerant as the refrigerant depending on the type of fish, and/or by appropriately selecting the thickness of the partition wall. The shape of the transportation box of the present invention may be rectangular, circular, oval, etc., and the ratio of the live fish storage chamber to the refrigerant storage chamber is determined according to the predetermined cold storage time (transportation time), and therefore the size of the container described above. , is appropriately determined depending on the thickness of the partition wall, water temperature, type of live fish, etc. In addition to the three-chamber structure as shown in FIGS. 1 and 3, a two-chamber structure in which a live fish storage chamber is divided into a refrigerant storage chamber by a single partition wall may be used. As the refrigerant used in the present invention, ice, a cold storage agent such as "Icenon (registered trademark)", etc. are suitable. "Action" and "Effect of the invention" The live fish storage chamber of this invention is made of foamed synthetic resin.
Since the chamber is divided into a live fish storage chamber and a refrigerant storage chamber by a porous partition, the strength will not be reduced by water, and the cargo will not collapse even when stacked in large numbers.
The cold air and cold water in the refrigerant storage chamber move to the live fish storage chamber through the thin wall portion of the non-porous partition wall, and are kept at the appropriate temperature for the live fish for a long period of time. Because the insulation performance is much better than that of a cardboard box, the cold retention effect and duration are greatly improved, and as a result, transportation by truck becomes possible and transportation costs are reduced. Does not use expensive films such as vinylidene chloride.
Since it is kept at a low temperature, the amount of oxygen consumed by live fish is small, and if there is a shortage of oxygen, it can easily capture oxygen through the air garn insertion port provided in the lid, and has many other advantages.
