Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a basket-car-integrated cold-keeping / heat-retaining box in which a car and a cold-keeping / heat-retaining box are integrated and can be assembled / folded.

[0002]

2. Description of the Related Art For example, various perishable foods, in-flight meals for airplanes, and the like need to be kept cold or warm, so that it is necessary to use a container having a function of keeping warm during cold transportation.

As a conventional transport container for keeping cold and warm, a prefabricated type box which is assembled by connecting a styrofoam carrying box or a heat insulating panel is used. The returnable box refers to a box that is repeatedly used without being disassembled after it is assembled once.

By the way, the former Styrofoam carrying box does not change in bulk even during empty transportation, and therefore there are problems that the transportation cost is high and it is difficult to dispose of it after the end of its useful life.

On the other hand, the latter prefabricated box has an advantage that it can be reduced in bulk during empty transportation, but has a problem that it requires much time and labor for assembling and disassembling. Further, styrofoam returnable boxes, prefabricated boxes, etc. are usually placed on a cart and transported, so in addition to the folding / assembling work of the box itself, the work of placing and lowering the box on the cart is added. The work is complicated. Also, even if you fold the box itself,
Since the basket car is bulky, it has a drawback that it requires a large storage space when not in use.

[0006]

SUMMARY OF THE INVENTION Therefore, the present invention has been made in view of the above-mentioned problems, in which a basket car for transportation and a cold insulation box are integrated, and the basket car is integrated. It is an object of the present invention to make it possible to assemble / fold a cool / heat-retaining box so that it can be easily assembled at the time of use, can be easily disassembled after use, and the storage space after disassembly can be reduced.

[0007]

In order to solve the above-mentioned problems, the present invention is as follows. In other words, the basket car integrated cold insulation box of the present invention is provided with a cold insulation box and a basket car on which the cold insulation box is loaded, and can be folded or assembled in a state in which these boxes are combined.

The cold insulation box is a foldable box constructed by connecting plate-like heat insulating members by a detachable joint portion or a foldable joint portion. In the cart, a wall member attached to at least two side surfaces of the cold insulation box is connected to a pedestal on which the cold insulation box is loaded by a detachable joint portion or a bendable joint portion. Wheels are attached to the lower portion of the wall member.

Here, of the side surfaces of the cold insulation box,
One or more side surfaces may be formed by connecting at least two plate-shaped heat insulating members so as to be bendable. At this time, among the wall members of the cart, the wall member attached to the side surface of the cold insulation box is formed by connecting at least two wall members so as to be bendable at positions corresponding to the connecting portions of the side surfaces. You may do it.

For example, in the case where the cold insulation box is constructed by bending the front plate and the top plate, the top plate and the back plate, and the back plate and the bottom plate so as to be bendable, and the other connecting portions being detachably connected. Is folded so that the front plate and the top plate overlap,
In this state, fold the top plate inward of the box so that it overlaps the back plate. Further, the bottom plate is bent upward so that it overlaps with the back plate. In this state, at least one of the left and right side plates may be folded inward at a right angle. However, if the side plate to be folded is bent around the connecting portion with the back plate as an axis, it cannot be bent at a right angle because it is obstructed by the front plate and the top plate that overlap with the back plate. Therefore, if the side plate to be bent is formed by connecting two plate-shaped heat insulating members to each other in the front-rear direction and the connecting portion is formed to be bendable, the heat insulating member located on the front side can be bent at a right angle. In this case, the width of the heat insulating member on the rear side (the length from the connecting part with the back plate to the end on the front side) is more than the sum of the thickness of the front plate and the thickness of the top plate that overlap with the back plate. The precondition is that

Correspondingly, the basket car can be exemplified by a basket car having a left wall surface, a back wall surface, a right wall surface, and a pedestal. Of the left wall surface and the right wall surface, the pedestal is
The joint portion of the cold insulation box with the wall surface attached to the non-foldable side plate or back plate is made foldable, and the bendable portion is made detachable at the joint portion with the wall surface attached to the side plate. Thus, when folding, the bottom plate can be bent upward at a right angle so that the bottom plate is folded so as to overlap the side plate or the back plate of the cold insulation box.
However, if the entire surface of the pedestal is bent, it interferes with the front plate, the top plate, or the bottom plate that overlaps the back surface of the cold insulation box, and therefore cannot be bent at a right angle. Therefore, the pedestal is constructed by connecting two plates back and forth. However, the depth of the bottom surface located on the rear side is equal to or greater than the sum of the thickness of the front plate and the thickness of the top plate that overlap with the back surface of the cold insulation box, or the thickness of the bottom plate of the cold insulation box.

Further, among the wall surfaces of the cart, the wall surfaces attached to the foldable side plates of the cold insulation box are:
Two wall members are connected to each other in the front-rear direction, and the connecting portion is configured to be bendable. However, the connecting portion is located at a position corresponding to the bent portion of the side plate of the cold insulation box. Thereby, the wall surface of the cart and the side plate of the cold insulation box can be bent together.

The heat insulating member of the cold insulation box is a laminated body composed of a polyethylene terephthalate film having at least metal vapor-deposited on both sides of an elastic plate-like foam material, a polyethylene film, a foamed polyethylene sheet, and a polyethylene cloth. May be included.

Examples of the foaming material include foaming polystyrene, foaming polyethylene, foaming polypropylene and foaming urethane, which may be used alone or in combination.

As described above, according to the basket car integrated type cold insulation / heat insulation box, the basket car and the cold insulation / heat insulation box can be simultaneously folded by a simple operation, and the basket car and the cold insulation / heat insulation box can be folded together. Due to
The occupied space when not in use can be reduced. For example, FIG. 11 shows a plan view of a basket car integrated type cold insulation box when folded. As shown in this figure, the depth of the basket car integrated type cold insulation box when folded is as follows: the thickness of six heat insulating members (30 x 6 m / m), the thickness of three wall surfaces, and the thickness of the basket car. The value is the sum of the thickness of one bottom plate, making it extremely compact.

Further, by adopting the structure having the reflection layers on both sides of the foam material as the heat insulating member of the cold insulation box, the heat insulating property is excellent and the contents can be kept at an appropriate temperature. In addition, impact resistance can be improved by adopting a configuration in which the basket car of the present embodiment has a structure in which three side surfaces of the cold insulation box are surrounded by robust wall surfaces.

In the second embodiment, an example in which the back plate and the top plate, the back plate and the bottom plate, and the top plate and the front plate are non-detachably connected has been described. However, these connecting parts use a surface fastener or the like. It may be detachable.

Further, in this embodiment, the cold insulation box having the front plate opened upward is shown as an example, but it may be opened laterally as shown in FIG. In the figure, the left peripheral portion of the front plate 3 and
The front side peripheral portion of the left side plate 5 is connected by a flexible hinge, and the front plate 3 is rotatable about the hinge. When the basket car integrated type cold keeping warm box adopting this configuration is folded, for example, as shown in FIG. 13, the first right wall surface 90 and the first right wall surface 90 of the basket car integrated cold keeping warm box are
The procedure of folding the front plate 3 inward after the right side plate 60 is folded can be illustrated.

It is obvious that the present invention is not limited to the configurations exemplified in the above-mentioned embodiments, and any folding point or folding procedure may be used as long as it satisfies the gist of the present invention.
