Description

The present invention relates to a heat insulating container.

Conventionally, packages such as fruits and vegetables have been transported from the shipping base to the destination by a refrigerated transport vehicle. In refrigerated transportation using a refrigerated transport vehicle, the refrigerating temperature of the luggage varies depending on the position where it is loaded in the vehicle, and the refrigerating effect is reduced due to loading / consolidating and unloading. In addition, when a refrigerated transport vehicle is used, the luggage may be transshipped on the way, or the luggage may be left at room temperature upon arrival. Therefore, even if the luggage is pre-cooled, it is difficult to maintain the low temperature state to the destination.

Therefore, at present, a technology is provided in a heat insulating container for storing luggage by providing a refrigerant storage space for storing refrigerant such as dry ice and a cold storage material, and supplying cold air from the refrigerant stored in the refrigerant storage space to the luggage. It has been proposed (see, for example, Patent Documents 1 and 2). By adopting such technology, it is said that the low temperature of the luggage can be maintained by the cold air supplied from the refrigerant. Further, in recent years, various heat insulating containers that can be disassembled and assembled have been proposed for the purpose of reducing the occupied space of the container after transportation of cargo (see, for example, Patent Document 3).

By the way, in refrigerated transportation using a refrigerated transport vehicle, it is common to supply air for precooling to luggage in a precooler to perform ventilation precooling, but heat insulation as described in Patent Documents 1 and 2. Since the side plate of the container is integrally formed with the bottom plate, if the ventilation precooling is performed with the luggage stored in the heat insulating container, the precooling air is blocked by the side plate and the cooling efficiency is lowered. There is. On the other hand, in the heat insulating container described in Patent Document 3, the side plate can be separated from the floor plate, but if the load is loaded on the floor plate without the side plate, the position of the load shifts and the loading operation is delayed. The problem can occur.

The present invention has been made in view of such circumstances, and it is possible to suppress the misalignment of the load during loading, improve the efficiency of the loading operation, and improve the cooling efficiency of ventilation precooling. The purpose is to provide a heat insulating container.

In order to achieve the above object, the heat insulating container according to the present invention is a substantially rectangular parallelepiped heat insulating container provided with a front plate, a rear plate, a pair of left and right side plates, a bottom plate and a top plate made of a heat insulating material panel, and has rigidity.

The third rear plate portion 23 of the above is bent toward the inside of the container with respect to the second rear plate portion 22 to cover the front of the laminated body P. As a result, the laminated body (front plate 10, side plate 30, top plate 50) P can be reliably protected, and the heat insulating container 1 is stored in a predetermined place in this state.

In the heat insulating container 1 according to the above-described embodiment, the first support portion 81 of the support member 80 having a substantially L-shaped cross section is arranged so as to be substantially parallel (substantially horizontal) to the bottom plate 40 and loaded. Can support luggage. At this time, the load can be loaded using the second support portion 82 that rises substantially vertically from the first support portion 81 as a guide (that is, while the edge portion of the load is brought into contact with the second support portion 82). Therefore, since it is possible to suppress the misalignment of the load during loading, it is possible to improve the efficiency of the loading operation. Further, ventilation precooling can be performed in the precooler while the load is placed on the support member 80 having a substantially L-shaped cross section. At this time, since it is not necessary to cover the other side surface with the heat insulating material panel, the precooling wind is not blocked and the cooling efficiency can be improved.
