Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a heat insulating storage box in which a low-temperature substance or a high-temperature substance is stored, and the substance is kept warm.

[0002]

2. Description of the Related Art Conventionally, dry ice has been
Shipped in a storage box made of insulating material. On holidays such as weekends, the manufactured dry ice may be stored in a warehouse in a state packed in a storage box and shipped after a holiday. By the way, as a storage box for storing dry ice, a foldable storage box is used in order to reduce bulkiness at the time of collection. That is, when storing dry ice, a plurality of plate members made of a heat insulating material were assembled into a box and used.

[0003]

However, in the storage box having the above-described structure, a slight gap is formed between the respective plates, so that the dry ice sublimates. When stored in a warehouse on a holiday in order to ship after a holiday, there is a problem that a large amount of sublimation occurs and the quality of a product is extremely deteriorated. Further, when dry ice is stored in the storage box, the storage box becomes heavy, and there is a problem that the bottom surface of the storage box is damaged or damaged when the storage box is transported by the roller conveyor. Also, in this storage box, a string for lifting and a string for binding are provided, but due to the ends of these strings, various sensors installed on a transfer conveyor or the like in an automatic warehouse may malfunction, There is a risk that these strings may get caught and hinder transportation.

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and is a foldable heat-insulating storage that can surely keep a heat-retained substance stored therein, and has reduced damage and damage during transportation. It is intended to provide boxes.

[0005]

In order to achieve the above object, a heat insulating storage box according to the first aspect of the present invention is constructed by assembling a plurality of plates formed of a heat insulating material into a box shape so that a low-temperature substance is contained therein. An insulated storage box in which a storage space to be stored is formed, wherein an inner fin is provided at an abutting portion between the plate members so as to straddle the abutting portion on an inner surface side to close a gap between the plate members. Is provided. As described above, since the inner fins are provided so as to straddle the abutting portions of the plates constituting the storage box and close the gaps, the airtightness in the storage space of the storage box is greatly improved, Thereby, the heat retention of the substance to be kept stored in the storage space of the storage box is favorably performed.

According to a second aspect of the present invention, there is provided the heat insulating storage box according to the first aspect, wherein a reinforcing layer formed of a harder material than the heat insulating material is provided on the bottom surface. In other words, since the rigid reinforcing layer is provided on the bottom surface, the rigidity of the bottom surface is increased, and even if the weight becomes large by storing the low-temperature substance in the storage space, it can be transferred by the transfer means such as a roller conveyor. In addition, the bottom of the storage box is reliably prevented from being damaged or damaged, and the storage box can be smoothly transferred.

According to a third aspect of the present invention, in the heat insulating storage box according to the first or second aspect, a pocket for storing and holding an end of a string for lifting or binding is provided. Features. As described above, since the pockets for storing and holding the ends of the lifting or tying cords are provided, it is possible to reliably prevent such a string from causing various sensors to malfunction. In addition, it is possible to prevent the string from being caught during transportation or the like.

It has been.

The bottom plate 2, the side plates 3, the front plate 4, the back plate 5, and the top plate 6 are made of a plate made of a heat insulating material, and the periphery thereof is covered with a sheet 7 having heat insulating properties. Have been done. The side plates 3, the front plate 4, and the back plate 5 are connected to the bottom plate 2 by a connection sheet 8, and the top plate 6 is connected to the back plate 5 by the connection sheet 8. The respective plate bodies are hingedly connected to each other at a connection position by the connection sheet 8.
That is, the storage box 1 is folded by rotating the plates connected at these connection points.

Outer fins 11 and 12 are provided on the upper surface plate 6 at an end on the side where the two side plates 3 abut and on the side where the front plate 4 abuts. ,
Outer fins 13 are provided at both end portions on the side where they abut against both side face plates 3.
Is provided. And these outer fins 11, 12,
Numeral 13 covers the abutting portion between the respective plate members on the outside thereof. In addition, the outer fin 13
It is configured to be fixed to the both side plates 3 by a cloth fastener 14. A binding belt 16 whose length is adjusted by a binding hook 15 is attached to the front plate 4 and the side plate 3.
Is provided, and this stopper 17 is provided.
The outer fins 11 and 12 are stopped by the cloth fastener 18.

The both side plates 3 are provided with inner fins 21 on the inner sides at both side ends thereof.
Are fastened to the inner surfaces of the front plate 4 and the back plate 5 by the cloth fastener 22 so as to close the butted portions of the respective plate members inward. In addition, these both side plates 3 are provided with inner fins 23 at their upper ends, and these inner fins 23 are connected at their ends by a cloth fastener 24 to close the upper side of the storage space S. It has become.

The storage box 1 is provided with lifting belts (lifting strings) 25 which are turned to the bottom side and are disposed upward from the front and back sides. It can be lifted by hooking a crane or the like. The lifting belt 25 is supported on the front plate 4 and the back plate 5 by a support 26.

The front plate 4 and the back plate 5 are respectively provided with pockets 27 (the pockets of the back plate 5 are not shown). In these pockets 27, a lifting portion 25a formed by an end of a lifting belt 25 is provided. It can be stored and held. The lower surface of the bottom plate 2 constituting the storage box 1 has a reinforcing layer 28 made of a synthetic resin or the like having a higher hardness than the heat insulating material forming the bottom plate 2.
