Means for Solving the Problems The present invention relates to a cool and heat retaining box, which is constituted as follows in order to solve the above-mentioned technical problems. That is, the present invention provides a collapsible cold insulation formed by connecting a bottom plate, a back plate, two side plates, a top plate, and a front plate formed of a plate-shaped heat insulating member to each other by a detachable or bendable joint. A heat insulation box, wherein the bottom plate of the cool heat insulation box is provided with an inverted V
A bent portion is formed along the width direction of the back plate so as to be foldable into a letter shape, and the front plate of the cool and heat retaining box main body is formed by a bent portion which divides the front plate into upper and lower door plates and an upper door. When the cold insulation box is folded, the bottom plate is folded in an inverted V-shape, the lower door plate is bent inside the upper door plate at the bending portion, and the bottom plate and the front plate are folded. Each bent portion is positioned so as to be close to each other in the up-down direction, and the top plate is positioned by being rotated about the connection portion with the back plate in an upper space portion of the front plate folded along with this, Thereafter, one side plate is folded inward.

Further, the present invention relates to a car having the above-mentioned cool and heat-retaining box integrally attached thereto and capable of folding or assembling both with the cool and heat-retaining box mounted thereon, wherein at least two side plates of the cold and heat-retaining box are provided. A car body and a traveling means attached to a lower part thereof, which are interconnected by a detachable or pivotable connecting portion with an enclosure surrounding the outer frame and a pedestal plate on which the cold insulation box is loaded, When folding the cold insulation box with the car body, the bottom plate is folded in an inverted V-shape, the lower door plate is bent inside the upper door plate at the bending portion, and each of the bottom plate and the front plate The bent part is positioned so that it is close in the vertical direction,
In accordance with this, the top plate is rotated and positioned around the connection portion with the back plate in the upper space portion of the folded front plate, and then one of the side plates is in contact with the surrounding frame of the car body. Disengaged and bent inward, fold the pedestal plate of the car on this side plate so as to overlap it, and then fold the enclosure removed from the side plate so as to overlap the pedestal plate. It is characterized by having done.

<Specific Configuration in the Present Invention> The car-car-integrated cold insulation box of the present invention comprises the essential components described above, but is established even when the components are specifically as follows. I do. The specific constituent element, the one side plate of the cold insulation box is formed by connecting at least two plate-shaped heat insulating members in a freely bendable manner,
The surrounding frame of the car body attached to the one side surface is constituted by two surrounding frame portions which are connected to bendable at a position corresponding to the connecting portion on the one side surface. I do.

The reason for this configuration is that if the side plate to be folded is bent around the joint with the back plate, it cannot be bent at a right angle because it is obstructed by the front plate overlapping the back plate. If the two plate-shaped heat insulating members are connected back and forth by a bendable connecting portion, the heat insulating member located on the front side of the side plate can be bent at a right angle.
In this case, the width of the rear heat insulating member (the length from the joint with the back plate to the front end) is the thickness of the folded front plate overlapping the back plate (thickness of the lower door plate). And the thickness of the upper door plate).

The enclosure to which the foldable side plate of the cool and heat retaining box is fastened is also formed by connecting two surrounding frame portions back and forth, and the connecting portion is formed by bending the side plate of the cool and heat retaining box. It can be bent at a position slightly ahead of the position corresponding to the portion. Thus, the side plate of the cold insulation box can be folded inward, and then the pedestal plate of the car can be folded, and then the surrounding frame of the car can be folded inward.

Such a car is, for example, a left frame,
One composed of a back frame, a right frame, and a pedestal plate can be exemplified. The pedestal plate is fixedly connected to each of the left and right enclosing frames, which are fastened to the unfolded side plate or the back plate of the cool and heat retaining box, and is attached to and detached from the enclosing frame fastened to the folded side plate. It is free.

The pedestal plate is preferably formed by connecting two plate members back and forth. In this case, the depth of the plate member located on the rear side is inverted V overlapping the back plate of the cool and heat insulating box. It is necessary that the thickness be equal to or greater than the total thickness of the bottom plate folded in the shape of a letter and the side plate overlapped with the bottom plate. Further, when the pedestal plate is folded so as to overlap with the folded side plate of the cold insulation box, it is preferable that the pedestal plate is fixed by a locking means so as not to fall down.

Further, in the car-insulated cold insulation box of the present invention, the plate-shaped heat insulating member constituting the cold insulation box is made of polyethylene having at least metal vapor-deposited on both sides of an elastic plate-shaped foam material. You may make it have the laminated body which consists of a terephthalate film, a polyethylene film, a foamed polyethylene sheet, and a polyethylene cloth.

Here, examples of the foaming material include those formed of foamed polystyrene, foamed polyethylene, foamed polypropylene, and foamed urethane alone or in combination.
