BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a truck for a cold storage container.

[0002]

2. Description of the Related Art Conventionally, mainly frozen products such as fresh food are
It is packed in a cold storage container made of synthetic resin, metal, etc., which has a thin box-like shape with an open top and a perforated structure or mesh structure for ventilation at the bottom or side wall, and stacks this in a basket-shaped rack for freezing. They are brought in, frozen and then shipped out for distribution by trucks or the like.

If the truck is a cold storage vehicle, the container loaded from the freezer to the rack and discharged is reloaded on the cold loading platform of the truck. In the case of a truck other than the cold storage vehicle, a cold storage box having a structure capable of maintaining the frozen state The boxes will be replaced and the boxes will be loaded onto the truck bed and transported.

[0004]

However, according to the above-mentioned conventional technique, when the container is loaded into the freezer, the container is loaded into the rack or trolley and loaded, and then the container is unloaded in the freezer and reloaded. When the container is loaded, the rack or trolley is loaded again. There is a problem in that the work is not easy because it requires a lot of work, especially because it is handling frozen foods.

Further, when the cold insulation box is used, it is not necessary to re-load the container into the truck, but since the cold insulation box has an insulating structure, the volume is large and the number of containers that can be loaded in the truck at one time is very large. However, there is a problem that the transportation efficiency is remarkably reduced and the transportation cost is increased, and a large number of expensive cold storage boxes must be prepared, and the storage space is also required.

In view of this, the present invention allows freezing processing while the container is loaded on the trolley, and can be transferred to the cold storage car as it is when leaving the garage. At that time, even if the entire trolley is loaded on the truck, the distribution of the cool air is maintained. An object of the present invention is to provide a cart for a cold insulation container that does not cause a change in the frozen state by shutting off.

[0007]

Means for Solving the Problems As a means for solving the problems of the above-mentioned prior art, the present invention is to stack thin box-shaped containers that are stackable and have a breathable bottom surface such as a mesh. A cold carrier container truck that is capable of loading containers on the upper surface, has a frame portion on four sides, and has wheels mounted on the lower surface thereof, and a frame portion that is opposed to the frame portion. A rail, a shutter plate whose both end portions are engaged with the rail and is inserted from one or both ends of the underframe so that the shutter plate can be pulled out, and locking means for maintaining the inserted state of the shutter plate are provided. ) Sometimes, the shutter plate is pulled out to open the underframe so that cool air is circulated through the container loaded on the trolley, and after freezing, the shutter plate is inserted to block the cool air.

[0008]

[Function] When the container is loaded into the freezer and the foods therein are frozen, the containers are stacked on the trolley as a stack of heavy boxes, manually loaded into the freezer, and after the position is determined, the shutter plate of the trolley is set. Pull out to open the underframe.
As a result, the cold air in the freezer enters the inside of the shutter part of the lowest container, and the cold air is supplied to the stacked containers to freeze the food items inside.

When the container after freezing is unloaded and used for transportation, the shutter plate is inserted while the container with the frozen food inside is loaded on the trolley, the underframe is closed to block the cold air, and the unloaded container is unloaded. Load the truck along with the truck onto the cold storage truck.
As a result, the space occupied in the truck bed is only the projected area of the truck, so the number of loaded containers can be increased, and the cool air inside the containers can be prevented from being dissipated by the shutter plate, causing a change in the frozen state. Absent.
