Description

[Detailed description of the invention] "Field of industrial application" The present invention relates to a transport box for live fish, etc., and more specifically, to a transport box for live fish, etc. that is inexpensive, does not collapse, has a long cooling time, and can be transported by truck. It is something.

``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 using this method, the strength of the cardboard box decreases due to internal moisture, causing the cargo to collapse when stacked during transportation or storage. Vinylidene chloride is expensive, and has little cooling effect, so it is difficult to use live fish. Despite the high consumption of oxygen, it is virtually impossible to supply oxygen from outside the cardboard box, 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 transport box for live fish etc. that eliminates these drawbacks.

That is, the present invention consists of a lid body and a container made of expanded styrene resin, and the container maintains the shape and strength as a partition wall, but the porous partition wall made of expanded styrene resin has fine voids formed between each fused particle. It is divided into a live fish storage chamber for storing water and live fish, and a refrigerant storage chamber for storing water and a refrigerant, and the cold water in the refrigerant storage chamber is transferred to the live fish storage chamber by capillary action via a porous partition wall. The contents are a transport box for live fish, etc.

To explain the embodiment of the present invention based on the drawings, in FIG. , 3 into a live fish storage chamber 5, 5 for storing water and live fish 4, and a refrigerant storage chamber 7 for storing water and 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 wall portion is destroyed by the pressure of oxygen, and the inside of the live fish storage chambers 8, 8 is filled with oxygen, and then sealed with a tape seal or the like.

FIG. 2 shows another embodiment of the present invention, and shows an example in the case of saltwater fish. That is, when ice is used as a refrigerant, for example, when the ice is directly poured into seawater (salt water) as shown in FIG. 1, the concentration of seawater gradually becomes thinner as the ice melts. Therefore, in the case of FIG. 2, ice 6 is sealed in a bag 9 made of polyethylene, for example, and is floated in water. Needless to say, such considerations are unnecessary in the case of freshwater fish.

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, the porous partition wall 3 is in 100% contact with the live fish storage chamber 5, so the cold water in the refrigerant storage chamber 7 is most effectively transmitted to the live fish storage chamber 5, and the temperature can be maintained within the desired temperature range for a long time. I can do it.

The transportation box of the present invention is particularly preferably made of expanded polystyrene, which has appropriate rigidity as a box and has excellent heat insulation properties. The perforated partition wall of the present invention may have holes drilled after molding, but the shape and strength of the partition wall can be maintained by widening the steam slit pitch of the mold during molding or restricting the amount of steam inflow by using only cut holes. This can be obtained by forming the particles into a so-called "okashi-like" shape to the extent that fine voids are formed between each fused particle. The degree of porosity is determined by comprehensively considering the container, the thickness and surface area of the partition wall, water temperature, type of live fish, transportation time, etc.

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 based on the predetermined cooling time (transportation time), the thickness of the partition walls, and the like. It is determined appropriately depending on the surface area, water temperature, degree of porosity, etc. In addition to the three-chamber structure as shown in FIGS. 1 and 2, 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.

"Function" and "Effect of the invention" The transportation box for live fish, etc. of the present invention is made of foamed styrene resin and is divided into a live fish storage chamber and a refrigerant storage chamber by a porous partition wall, so there is no possibility that the strength will be reduced by water. The cold water in the refrigerant storage chamber is transferred to the live fish storage chamber by capillary action through the porous partition walls, and is kept at the appropriate temperature for live fish for a long time.It is more insulated than cardboard boxes. Because of its much superior performance, the cold storage effect and duration are greatly improved, and as a result, transportation by truck becomes possible and transportation costs are reduced.
It does not use expensive films such as vinylidene chloride, and because it is kept at a low temperature, the amount of oxygen consumed by live fish is low, and if oxygen is insufficient, oxygen can be easily replenished from the air gun socket provided on the lid. It has many advantages such as:
