[0003] As a cooling method, for example, a method of spraying crushed ice or spraying cold water on an article is known. In recent years, contents have been packed in an open container such as a cardboard box, and the like.
A method of pre-cooling by blowing low-temperature air (cold air) through the holes of a cardboard box, or a so-called vacuum that uses boxed contents in a vacuum tank and uses latent heat cooling accompanying evaporation of moisture from the contents Since the cooling method has a feature that cooling can be performed in a short time without deteriorating the quality of the contents, the cooling method has been spread nationwide.

[0004] By the way, as a container for accommodating the contents, a cardboard box or a container made of a foamed resin is usually used. However, after the contents are accommodated in these and pre-cooled, the contents are not exposed to the outside temperature. In order to prevent this, a method of covering with a lid, packing and shipping is widely adopted. However, in such a method, the container is put into a pre-cooling box without a lid for pre-cooling treatment, taken out from the pre-cooling box after pre-cooling, covered with a lid for cooling, and further banded, so that much labor is required. Therefore, the development of a container capable of efficiently performing pre-cooling processing such as vacuum pre-cooling and ventilation pre-cooling of the contents while the lid is kept on the container, and capable of carrying out cold preservation without requiring labor for packing after the pre-cooling processing has been expected.

[Problems to be Solved by the Invention] However, in the case of a cold storage container having a notch at the corner of the lid and a small lid which can be fitted and removed, the small lid is removed before the pre-cooling process, and the pre-cooling is performed. The lid must be closed after processing. That is, if the small lid is removed, it is possible to perform the pre-cooling process with the lid closed, but when taking out from the pre-cooled refrigerator, the high temperature outside air will enter if the small lid is not manually reattached to the notch and closed. There was a risk that the inside would heat up. As described above, the conventional container requires a remarkably complicated operation since the small lid is inserted and removed each time before and after the pre-cooling treatment, and therefore, there is a danger that the small lid is left closed or opened due to carelessness or erroneous operation. And the container cannot be automatically sealed after cooling.

In the drawings, reference numeral 30 denotes a pneumatic telescopic plunger. This air pressure type telescopic plunger 30
Is formed of an elastic material such as plastic so that the whole has a closed hollow cross section. A shaft 33 having a retractable bellows portion 31 at a lower portion and a receiving portion 32 for supporting a ball type intake / exhaust valve formed at an upper portion extends vertically from the upper end of the bellows portion. This pneumatic telescopic plunger 3
Numeral 0 designates a concentrically arranged space below the intake / exhaust valve 7a while maintaining a gap between the plunger 31 and the vent hole 4, as shown in FIG. The entire stroke length is apparently reduced to a minimum length, and the intake / exhaust valve 7a is locked on the closing portion 5a. When the plunger is left in an atmosphere having a pressure lower than the atmospheric pressure, the air inside the plunger expands, and the bellows portion 31 extends, whereby the stroke of the shaft portion 33 increases, thereby closing the intake / exhaust valve 7a. It is configured so that it can be pushed up to move upward from 5a.

Next, the operation of this embodiment will be described. First, after articles (for example, vegetables) that need to be kept cool are stored in the container body 1, the lid 2 is fitted to the opening surface of the container. Then, in this state, the container is quickly degassed with a pre-cooled refrigerator, for example, a vacuum pump using a vacuum pump. is there. That is, the container is covered, the container is accommodated in a vacuum tank, and the container is evacuated from the atmospheric pressure to a required pressure by a vacuum pump. Shaft part 3
3, the receiving portion 32 provided above the shaft portion mechanically directly pushes up the sphere 6a as shown by the imaginary line in FIG. 2 to open the closing portion 5a. As a result, the air inside the container is reliably exhausted from the external communication port 8b through the communication port 10 formed at the upper end of the ventilation hole with the inside of the container, whereby the contents in the container can be cooled in vacuum. .

When the vacuum cooling process is completed and the inside of the vacuum tank is returned to the atmospheric pressure, the plunger 30 is deformed by the external pressure and the bellows portion 31 is reduced. In that case,
First, the sphere 6a is floated by the air flowing from the external communication hole 8b, and the intake / exhaust valve 7a is opened to allow the air to flow into the container. However, thereafter, both the inside and the outside of the container have substantially the same pressure, so that the sphere 6a returns to the closing portion 5a and closes it. Therefore, the ventilation hole 4 is automatically closed, and the inside of the container can be protected from the outside air temperature.

[Effects of the Invention] As described above, the insulated container according to the present invention efficiently vacuum-cools the contents even when the container is covered or when the containers are stacked in a vacuum precooling process. After the vacuum cooling, the vent can be automatically closed to protect the inside of the container from the outside air temperature. Accordingly, there is an advantage that the cold transport can be performed without troublesome packing.
