Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cargo box for storing cargo in a refrigerated freight car.

[0002]

2. Description of the Related Art Cooled articles such as frozen foods and fresh foods are transported under proper temperature control suitable for freezing, refrigerating or keeping cold so as to maintain the freshness of the articles or the form of the articles. In recent years, in transporting these articles, it has been required to mount these articles having different proper temperatures on one vehicle and to transport them at the same time, and various luggage box structures for that purpose have been proposed.

For example, in Japanese Utility Model Publication No. 7-32183, a movable partition wall that moves in the front-rear direction of a vehicle is provided inside a luggage box, and the partition walls serve as a plurality of storage chambers that are separated from each other. There is disclosed a refrigeration van type vehicle in which each storage chamber can be controlled to an appropriate freezing, refrigerating, or keeping temperature. Further, in Japanese Utility Model Laid-Open No. 4-90883, a small-volume heat-insulating luggage box formed integrally in advance in the luggage box body is inserted through an opening provided in a side wall of a vehicle, and a cooling device is provided therein. A luggage box structure of a van type vehicle capable of simultaneously carrying general cargo and frozen food is disclosed.

However, in the storage chamber defined by the movable partition wall in the packing box, an operation space around the partition wall is required for moving the partition wall, which may occur during transportation. The movement of the wall for changing the load volume during the loading and unloading work of the frozen foods of 1) had poor work efficiency, and during that time, the cooling efficiency decreased, and proper temperature control was difficult. In addition, the proportion of frozen foods, etc. as goods to be carried is smaller than that of general cargo, but nevertheless, when the packing box is defined in this way, the partition wall becomes large and the weight is heavy, so moving work is difficult. It was difficult to do, or it was difficult to maintain heat insulation at the contact surface between the outer peripheral edge of the partition wall and the inner wall surface of the packing box.

Further, although the small storage chamber inserted into the luggage box disclosed in Japanese Utility Model Laid-Open No. 4-90883 cannot have a protruding portion outside the small storage chamber because of the structure for inserting the small storage chamber. For this reason, if cooling equipment is installed, thick parts such as the evaporator will not be fully accommodated and will protrude from the inner wall surface, which hinders loading and unloading operations, making it impossible to effectively utilize the interior of the room. Moreover, there is a problem that it is difficult for a worker to enter the inside of a small-sized storage room having a low ceiling from one side of the vehicle and work.

[0006]

SUMMARY OF THE INVENTION The present invention has been devised to solve such a problem, and various cooling articles having different proper temperatures are simultaneously transported by one vehicle to each shipping destination. The present invention provides a packing box structure suitable for small-lot transportation. In particular, as recently, a distribution facility with a subdivision function for direct retail delivery, in which cooling items are subdivided according to the shipping destination and sent directly to the store, is provided. If the frequency of loading and unloading becomes high and the temperature of the storage chamber rises each time, it becomes difficult to manage the proper temperature of the article being cooled. In the present invention, for example, a -18 degree frozen article, a -5 degree refrigerated article, a 5 degree cold insulated article, or in the case of a dry van, ordinary cargo that is stored at room temperature is divided into a single cargo box. (EN) A cooling box is provided in a storage room to enable proper temperature control, and a packing box structure with good work efficiency in these small storage rooms is provided.
