Description

[Detailed description of the invention] This invention relates to a container for transporting perishables at low temperatures.In addition to improving cooling efficiency by using a coolant such as ice, the quality of stored items can be maintained and handled without ice etc. coming into direct contact with the stored items. I'm trying to get something useful.

Traditionally, fruits, canola, and other perishables (perishable foods) have been transported using various low-temperature methods for the purpose of preserving freshness or preventing quality changes. In cases where ice etc. is used in a state where it is easy to come into direct contact with fresh produce, it may cause low temperature damage to the produce due to supercooling.
In addition to the risk of quality deterioration, it is also necessary to prevent water and coolant produced by melting ice from leaking outside.

Therefore, in this invention, we provide a container for low-temperature transportation that can eliminate all of the above-mentioned drawbacks, and its structure consists of a container body, an inner lid, and an outer lid made of composite or resin foam. The lids are assembled in a sequentially fitable manner, and the peripheral wall of the container body has a cooling air circulation groove, the lower end of which is closed, and the inner lid that closes the storage chamber of the container body has a The present invention is characterized in that a circulation groove communicating with the above-mentioned circulation groove is formed, and a storage portion for a coolant such as ice, which communicates with the circulation groove, can be formed between the outer cover and the outer cover.

Next, embodiments of this invention will be illustrated below with reference to the drawings.

10 is a container body, 20 is an inner lid, and 30 is an outer lid, all of which are made of foamed resin such as expanded polystyrene, and have shapes that can be fitted in sequence. The inner lid 20 is designed to allow the storage section 11 of the container body 10 to be closed, and a storage section 21 for a coolant such as ice can be inserted between the inner lid 20 and the outer lid 30. .

Furthermore, reference numeral 12 denotes a cold air circulation groove formed in the peripheral wall 13 of the container body 10. In particular, the lower end of the circulation groove 12 is closed to prevent cold air from leaking to the outside. 13, the flow groove 12 is also connected to the container body 1.
It is preferable to apply the shape intermittently on the four sides of 0.

Reference numeral 22 denotes a circulation groove formed in the inner lid, which is shaped so as to communicate with the circulation groove 12 of the container body 10, and is connected to the storage section 21 for a coolant such as ice to facilitate the circulation of cold air. There is.

In addition, when stacking during use, the outer lid 30 is fitted only to the container located at the top as shown in FIG.
It is economical to place the container directly on the container body 10, and the storage section 11 of the container body 10 is also cooled by the coolant such as ice stored in the lower inner lid 20, resulting in better cooling efficiency. becomes.

Next, examples of changes to the inner lid will be explained with reference to FIG. 4 and subsequent figures.

The inner lid 20' is completely fitted inside the container body 10 and is not exposed to the outside.

That is, the peripheral edge of the inner lid 20' is placed on the inner edge of the peripheral wall 13 of the container body 10, and the peripheral edge of the inner lid 20' is intermittently cut out, and the cut out parts are exposed to cold air. This groove is formed in the peripheral wall 13 of the container body 10 through the groove 22' which is formed by being removed from the storage section 21 for a coolant such as ice in the center of the inner lid 20'. It leads to 12.

Further, a recess 31 is formed in the outer cover 30 at a location corresponding to the circulation groove 22' of the inner cover 20' to further improve the circulation of cold air.

If the inner lid 20' as described above is used, the inner lid 20' is inserted into the container body 10, so when the containers are stacked and used, the load is supported by the peripheral wall 13 of the container body 100, and the inner lid 20' is inserted into the container body 10. Since no load is applied to the housing 21, there is no need for much strength, and in terms of heat insulation, it is advantageous in that heat transfer from the outside to the storage section 21 of ice and the like can be reduced.

In practice, the synthetic resin foam forming the container body 10, the inner lid 20, and the outer lid 30 can be formed from polyethylene, polypropylene, and various other foams in addition to expanded polystyrene.

According to this invention constructed as described above, a circulation groove is formed in the peripheral wall of the container body, and a circulation groove communicating with the above-mentioned circulation groove is formed in the inner lid that closes the storage area of the container body. , the cold air from the storage area for coolant such as ice provided between the inner lid and the outer lid is introduced into the storage area of the container body through the circulation groove of the inner lid and into the circulation groove of the container body. This device cools fruits, canola, and other perishables as evenly as possible from the periphery, rather than just from the bottom of the storage compartment for ice, etc., so cooling is not concentrated in one area and supercooling is achieved. can be prevented and cooling efficiency can be improved.

In addition, since cold air is not applied directly to perishables but is cooled through the foam walls, there is no quality deterioration such as low-temperature damage caused by cold air, and the product does not emit gases that are harmful to perishables as a cooling agent. It is also safe to use.

In particular, since the lower end of the circulation groove in the container body is closed, melt water generated when ice is used as a coolant does not leak out from the circulation groove, and it also prevents outside air from entering. In addition to being suitable for preventing deterioration of the cooling function due to air pollution, it is also easy to handle without polluting the surrounding area.

Therefore, it is possible to maintain very good cooling conditions for transporting or storing perishables, and it is now possible to store mushrooms and various other perishables such as fresh shiitake, which were previously extremely difficult to maintain at low temperatures, without deteriorating their quality. It can be widely used as a suitable container for
