包する。``Prior art'' ``Problems to be solved by the invention'' Today, it has become common to pre-cool vegetables before shipping them. Advantages of precooling include stable quality, shipping to remote locations, and adjustment of shipping location, and one of the precooling methods is vacuum precooling. Vacuum precooling is a method of cooling vegetables by removing the heat of evaporation that accompanies water evaporation from vegetables, and has the advantage of fast cooling speed and uniform cooling. However, on the other hand, there is a problem in that high-temperature outside air flows into the container from the opening for vacuum cooling during storage or transportation, reducing the cold insulation effect.

No. 21569 proposes a cold storage container having a structure in which an opening leading to the inside of the container is formed in a fitted state with a lid, and the opening is closed in the opposite fitted state. However, in the case of such a cold storage container, it is necessary to reload all the cargo in the vacuum precooling chamber in order to turn the lid in the opposite direction after vacuum precooling, which has the disadvantage of greatly reducing work efficiency.

Figure A shows the front side of the container body in Figure 1, and Figure 2B shows the opposite side. In these figures, on the near side, the convex edge part 3 is bent in an "inverted dogleg" shape on one side of the curved part from the outer circumferential side to the inner circumferential side, and the opening has a high pass-like shape at approximately the center. A portion 5a is carved, and on the other side, similar openings 5b are carved at 180 degrees symmetrical positions.

が挙げられる。 If the opening is too large, the vacuum pre-cooling speed will increase, but outside air will easily flow in after pre-cooling, reducing the cold insulation effect.On the other hand, if the opening is too small, the inflow of outside air will be suppressed after pre-cooling. , the precooling rate decreases. Therefore, the minimum area of the opening is preferably about 0.5 to 1.5 cm2 . For example, when cooling the container from an outside temperature of 20°C to an internal temperature of 5°C, the minimum area of the opening is approximately 5 mm x 10 mm. Once an opening is provided, replacement with cold air can be achieved in about 10 minutes. It is also necessary to provide at least two openings, and from the standpoint of cooling efficiency, it is desirable to provide them diagonally across the container.
In this example, the openings are provided diagonally at approximately the center of the long side walls, but the openings are not limited to this, and it is also a preferable embodiment to provide them, for example, at diagonal corners. The synthetic resin for the foamed molded article used in the present invention is preferably one that has a certain degree of rigidity and low thermal conductivity, such as polystyrene resin.

減ずることがない。 Secondly, after pre-cooling, the inside of the container is kept at a lower temperature than the outside temperature, so the specific gravity of the air inside is greater than that of the outside air, resulting in a difference in specific gravity. Although the container of this invention is an insulating material, the internal temperature tends to rise slightly over time from the outer periphery of the container, so the internal air is gradually expanding and becomes slightly pressurized. . This outflow of internal air to the outside is prevented by forming the opening into a weir or bottleneck structure that provides natural ventilation resistance. Furthermore, even if outside air were to flow in, there would be a difference in specific gravity, and furthermore, the outside air would have to pass through a small space such as a weir or a dam formed between the back of the lid and the opening.
This will prevent outside air from flowing into the interior. As a result, the flow of air between the inside and the outside containing the object to be refrigerated is substantially cut off, and the cooling effect is hardly reduced.

内部に流入することがない。 Thirdly, since the opening has a weir or bottleneck structure that provides natural ventilation resistance, outside air is structurally prevented from flowing into the container under normal pressure after pre-cooling, and due to the difference in specific gravity, physical Because it is blocked by
Due to the synergistic effect of these two, outside air does not substantially flow into the container.

せしめ、真空予冷によるコストアツプを画期的に
抑制し得るもので、その実用性は頗る大である。``Effects of the invention'' As mentioned above, although the invention provides an opening in a container with heat insulation performance, it is difficult to solve the problem of a weir or bottleneck structure where there is a difference in specific gravity between the outside air and the atmosphere inside the container and natural ventilation resistance. By using minute openings to substantially prevent natural ventilation between the inside and outside air, it is possible to maintain a sufficient cold retention effect without closing the openings after vacuum precooling, which dramatically improves work efficiency. It is possible to dramatically reduce the cost increase due to vacuum precooling, and its practicality is extremely high.
