Description

[Detailed Description of the Invention] The present invention relates to an insulated container for transportation in which a truck part and an insulated container part can be folded together.

When transporting seafood products, processed frozen foods, ice cream, frozen foods such as frozen meat, ham, sausages, butter, cheese, fish paste products, and low-temperature foods such as cakes and breads from food factories to each store. One way to save labor and speed up the process is to use a cold roll box, ie the Swedish method. A cold roll box is a refrigerated container equipped with wheels for convenient loading and unloading. Food is packed into the container and transported to the destination using a refrigerated truck or freezer. At the destination, the food is packed. It is rolled up and brought into the store. However, cold roll boxes are expensive and have the problem that they cannot be folded compactly and stored even when empty after use. In other words, since it is expensive, it is necessary to increase the operating rate and use it effectively, which means that many spare cold roll boxes cannot be installed, and they may not be ready in time for emergency transportation.
There is a problem in that transportation management becomes complicated because a plan for using the cold roll box must be carefully prepared in advance. Furthermore, since it cannot be folded compactly for storage, a large space must be provided when empty cold roll boxes are collected by truck or stored in a warehouse, leading to an increase in the number of times the truck has to be sent back. .

From this point of view, a simple type of cold roll box that is inexpensive and easy to store, such as a simple type consisting of a trolley and a heat insulating sheet, has recently been attracting attention. However, the conventional simple type had the problem that the storage work was complicated because the insulating container consisting of the trolley and the insulating sheet was separated and folded for storage.

With this reality in mind, the inventors of the present invention have conducted extensive research to provide a simple cold roll box that can be stored compactly by folding the trolley and insulating container into one unit. As a result, we arrived at the present invention.

Accordingly, the present invention has a ceiling surface having a diagonal cut portion made of a removable coupling means, and a floor surface in which at least three sides touching the side surfaces are removable or made of a flexible heat insulating sheet. It consists of a heat insulating container and a trolley whose floor surface and at least one side frame are bendable. By opening the coupling means of the diagonal cut in the ceiling surface, the heat insulating container can be folded into the floor surface and side of the trolley. To provide a heat insulating container for transport that can be folded into one body, and is characterized in that it can be folded and stored together with a frame.

The insulated transport container of the present invention will be described below with reference to the drawings.

FIG. 1 shows an example of a heat-insulating container used in the present invention. The heat insulating container 1 has a diagonal notch 2a formed by a coupling means that can be freely engaged with and detached from the ceiling surface 2. At least three sides of the floor surface 7 that contact the side surfaces 3, 4, 5, and 6 are detachable, and the remaining one side is bendable. Of course the remaining one
A removable coupling means may also be provided on the sides. As the removable coupling means, fasteners,
Examples include magic tape (registered trademark), buttons, hooks, or strings. In addition, to connect the floor and side surfaces, use Magic Tape (registered trademark name) by providing folds on the floor or side surfaces as shown in this diagram.
Alternatively, both sides may be directly joined with a zipper or string without providing a fold.

When folding the floor surface as shown in this figure,
It is preferable to connect the folded portion 8 of the floor surface to the inside of the side surface because it can be easily engaged with and disengaged from the side surface when the folded portion 8 of the floor surface is folded integrally with the floor surface of the truck, which will be described later. Further, it is preferable to take measures to allow one side of the container to be completely opened for ease of loading and unloading articles into the container.

Preferred examples of flexible heat insulating sheets constituting the heat insulating container include synthetic resin foams such as polyethylene foam, polypropylene foam, polystyrene foam, polyvinyl chloride foam, and polyurethane foam; Examples include laminated layers of foil, iron foil, aluminum vapor-deposited film, etc. as a light-shielding layer.

As shown in FIG. 2, the trolley used in the present invention basically consists of a floor surface 22 and side frames 21a, 21b, and 21c. The floor surface 22 can be bent in one direction, and the side frame 21a can be bent in the same way, so that when not in use, the floor surface and side frame can be folded to make a compact size. Store it. At this time, the planar shape seen from the top of the cart will be folded more into a 〓 shape than a 〓 shape.

Figure 3 shows an example of the insulated transport container of the present invention.
This is a combination of the above-mentioned heat-insulating container and cart. The heat insulating container 31 is engaged with the truck side frame 32 and/or the floor surface by a string, tape, or the like 33 as required. When in use, the connecting means in the notch 31a in the diagonal direction of the ceiling surface is locked, and the connecting means on the floor, side surfaces, etc. are locked, and the device is used in an airtight state.

FIG. 4 is a diagram showing the folded and stored state. By bending the floor surface of the cart upward, the floor surface of the heat-insulating container is also bent upward integrally. At this time, the means for connecting the floor and side surfaces of the heat-insulating container should be removed in advance, if necessary. Next, after opening the coupling means of the notch in the ceiling surface,
2 is folded inward, the ceiling surface 43 of the heat insulating container is bent downward (or upward), and the heat insulating container is also folded integrally with the side frame. As a result, the insulated containers for transportation have a square planar shape when viewed from above when in use, but become square-shaped when folded, reducing storage space and allowing storage to be stacked one on top of the other.

In addition, when using the stored insulated transport container of the present invention, the above-described operation may be performed in reverse. In other words, the bent side frames are returned to the outside to restore the side and ceiling surfaces of the insulated container to their original shapes, and the floor of the insulated container is lowered by lowering the floor surface of the cart that was bent upwards. All you have to do is return the surface to its original shape and engage each connecting portion.

The insulated transport container of the present invention can be folded into one piece without having to separate the cart and the container.
This will help speed up storage operations and save labor.
