And the container body as above With such a configuration, the corrugated board placed on the bottom wall and under the top wall of the corrugated board box 1 The expanded polystyrene plates 3 and 9 for preventing temperature rise in the box 1 can be omitted.

[0033]   Next, the packaging container of the present embodiment and the conventional packaging in which a cardboard box is filled with sawdust. The results of a comparative test on the temperature change inside the container during transportation with the container I will show you.

[0034]   The test conditions are as follows.

[0035]   Live Crustacean: Prawn   Transportation route: Kumejima (Okinawa) farm → Naha (Okinawa) → Osaka → Nara Central Wholesale                   Sales market (See Figure 9 for details)   Test packaging: cardboard box + water absorbing sheet + cool storage material (150g)   Comparative packaging: Cardboard box + sawdust (frozen at -20 ° C)   Test date: April 10 and 11, 1991   The test packaging container is the packaging container of this example. However, with the water absorbing sheet 5 In order to clarify the effect of the cold storage material 7, the packaging material in the cardboard box 1 shown in FIG. Except for the above, prawns were placed on the water absorbing sheet 5 as shown in the figure. . The packaging for comparison is a cardboard box filled with sawdust frozen at -20 ° C. The prawns were housed in this sawdust. Also, for temperature measurement of prawns Then, as shown in FIG. 8, the sensor 19 detects the intestinal temperature of the prawns 18, This was recorded by a micro memory coder (manufactured by Anritsu Keiki).

[0036]   The results of the above test are shown in FIG. It is clear from the graph in the figure As you can see, in the comparative packaging container, the temperature change of the prawn 18 is large. On the other hand, in the test packaging, the temperature change is small. Therefore In the packaging container of the present embodiment, compared with the packaging container filled with sawdust, It was found that the live shellfish can be transported at a constant temperature because they are not easily affected by temperature. This As a result, the mortality rate of live crustaceans can be reduced.

[0037]   As described above, the test packaging can maintain the temperature of the prawns 18 uniformly. The reason is as follows. That is, at the initial stage of transportation of the packaging container, the cold storage material 7 is used. Therefore, the temperature rise of the prawn 18 is suppressed. At this time, the water absorbing sheet 5 is It does not absorb the body fluids of prawns 18 so much and functions as a heat insulating material. Cooling is prevented. After that, when the function of the cold storage material 7 deteriorates, the prawn 18 Due to the water absorbing sheet 5 absorbing the body fluid having a low temperature, the temperature of the prawn 18 is increased. Suppressed. Also, due to the cooling action of the refrigerator during transportation, the cold storage material 7 and The water-absorbing sheet 5 is cooled to suppress the temperature rise of the prawns 18 and absorb water. The seat 5 prevents the shrimp 18 from overcooling. By the above action The temperature of the prawns 18 is kept almost constant.

[0038]   In April, when the above-mentioned comparison test was conducted, the temperature difference between the outside temperature and the prawn 18 Is relatively small, and during the summer when this temperature difference increases, the test package In the case of a packaging container, the temperature of the prawns 18 is increased by adjusting the amount of the regenerator material 7, for example. Since it is possible to suppress the rise, A larger difference will occur in the temperature equalizing function of the shrimp 18.

Further, the cardboard plate 22 is, as shown in FIG. The load of the regenerator material 7 whose projected area on the bottom is smaller than that of the shrimp 4 ... 4 so that the function of fixing the shrimp 4 on the water absorbing sheet 5 is secured. , Has an appropriate rigidity. In order to obtain such a function, dumbo The rule plate 22 has a thickness of, for example, about 5 to 10 mm. In addition, accumulation As a member arranged between the cooling material 7 and the water absorbing sheet 5, the cardboard plate 22 is a low-cost member. Although it is a strike, it may be any as long as it has an appropriate heat insulating function and rigidity. Instead of the rule plate 22, for example, a foamed resin plate can be used. On the other hand, cold storage If the projected area of the bottom surface of the material 7 includes the arrangement area of the shrimp 4, ... The member between the water sheet 5 and the water sheet 5 is not required to have any particular rigidity. It may be a foamed resin sheet having heat insulation and flexibility such as a heat insulating sheet. Also When selecting each of the above members, the amount of the cold storage material 7 is also taken into consideration. That is, the temperature is Since a large amount of regenerator material 7 is used in high summer, there is a risk that the shrimp 4 ... will be overcooled. is there. In this case, a relatively thick foam resin plate is used to obtain a high heat insulation function. Be done. Also, in winter when the temperature is low, a small amount of the cold storage material 7 is needed, so In addition, a low-cost cardboard plate 22 having a low heat insulating function can be used.
