[0002]

[Technical background of the device]

 Since it is lightweight and excellent in strength, it is made of synthetic resin because it is used as a so-called returnable container for storing and transporting various products such as food. Are widely used. In particular, when the contents are fresh food, relatively corrosive, winter coffee or freshly steamed products, it is preferable that the transport container that stores the contents has a cold insulation function. Therefore, recently, for the members that make up each wall surface of the shipping container, a plate material made of synthetic foam resin with air sealed inside is used, and the plate material is combined to form a container. A heat insulating layer is formed between the inside and the outside.

In addition, some of the transport containers may be assembled by interposing one or more rectangular tubular frame bodies (hereinafter simply referred to as tubular frame bodies) between the bottom plate and the top plate. is there. In this prefabricated transport container, the internal storage space can be increased depending on the size of the contents, or the internal storage space can be reduced by removing the tubular frame between the bottom plate and the top plate. Not only is it convenient and convenient, but the structure of the container is simple: the bottom plate, the top plate, and the cylindrical frame. It suffices to prepare these three elements in advance. It can be easily handled regardless of.

However, since this assembly-type transport container requires a certain level of connection strength, it is not possible to simply connect or disconnect each component, which is a troublesome thing. Moreover, since the tubular frame is provided between the bottom plate and the top plate, it is difficult to provide a function of keeping cold and warm because there are many joints and the air inside can escape easily. In particular, if an assembling-type transporting container having a cold and heat retaining function is used as the returnable container, the intermediate tubular frame cannot be miniaturized after the contents are stored and transported. It means that the size of is not much different from that of going.

FIG. 6 is a sectional view taken along line 6-6 of FIG.

As shown in FIG. 1, the transportation container 1 according to the present embodiment has a cold storage product such as fresh food, a relatively corrosive food, or coffee, a freshly steamed product, or the like. It is used as a so-called returnable box for storing and transporting heat-insulating products.

The container 1 is assembled and molded using a hollow plate in which air or a synthetic foam resin such as a heat insulating material is sealed so as to exert a cold and heat retaining function. The hollow plate forms a heat insulating layer that shuts off the inside and outside of the container with air or synthetic foam resin sealed inside, and prevents temperature changes of what is stored in the container as much as possible, corrosion or change in taste. The cold and heat retaining function can be exerted to prevent the occurrence of heat. It is preferable that the plate is made of a synthetic resin that is lightweight and excellent in strength, and it is preferable that the plate be formed by using polyethylene, polypropylene, or the like.

Further, it is preferable to use foamed polystyrene, foamed polyurethane or the like as the material of the synthetic foamed resin sealed inside the hollow plate. The carrying container 1 formed by using such a hollow plate has a bottom plate 2, a top plate 3 and one or a plurality of cylindrical frame bodies 4, 4.

The bottom plate 2, the top plate 3 and the tubular frame 4 have the same outer shape in plan view. However, preferably, the bottom plate 2 and the top plate 3 have the same outer shape in plan view. I wish I had it. This is so that the folded cylindrical frame bodies 4, 4, ... Can be sandwiched between the bottom plate 2 and the top plate 3 when the transport container 1 is disassembled as described later.

The bottom plate 2 and the top plate 3 serve as a bottom cover or a top cover of the transportation container 1. As shown in FIG. 2, the bottom plate main body 5 or the top plate main body 6 and each of these bottom plate main bodies 5 are provided. Or, it has side walls 7 and 8 which are integrally provided upright around the top plate body 6. Each of the side walls 7 and 8 has a short side and a long side, and the short side is joined to the joint end faces 9 and 10 joined to the cylindrical frame bodies 4, 4 ...

Preferably.

On the long side of each of the side walls 7 and 8, the same convex portions 11 and concave portions 12 are formed on the joint end surfaces 9 and 10 which are joined to the cylindrical frame bodies 4, 4 ,. Further, here, as shown in FIGS. 5 and 6, a connecting convex portion 13 and a connecting concave portion 14 that substantially join the bottom plate 2 or the top plate 3 and the cylindrical frame bodies 4, 4 ,. Has been formed. The connecting convex portion 13 is formed adjacent to the connecting concave portion 14, and is formed in such a shape that the concave and convex portions can be fitted to each other. The connecting convex portion 13 and the connecting concave portion 14 are engaged with the connecting convex portion 13s and the connecting concave portion 14s formed on the joint end surfaces Su, Sd of the cylindrical frame bodies 4, 4 ... And the cylindrical frame bodies 4, 4 ... In addition, a subscript "s" is attached to a cylindrical frame.

On the other hand, on the upper and lower joint end surfaces SU, Sd of the cylindrical frames 4, 4, ..., Convex portions 11, concave portions 12, formed on the side walls 7, 8 of the bottom plate 2 and the top plate 3, A concave portion 12s, a convex portion 11s, a connecting convex portion 13s, and a connecting concave portion 14s which are closely fitted to the connecting concave portion 14 and the connecting convex portion 13 are formed.

The tubular frames 4, 4 ... Can be bent at joints 17 (FIG. 2, FIG. 2) that are slightly displaced from the corners 16 of the long sides and the short sides toward the long sides. 7 and 8) are formed, and a hinge portion 18 that bends the short side portion inward is provided substantially at the center of the short side portion. The tubular frame bodies 4, 4, ... Can be folded by the joint portions 17 and the hinge portions 18, but the outer shape of the end faces of the tubular frame bodies 4, 4, ... When folded is a substantially square shape. The length A of one side of the square is approximately four times the inner dimension A of the bottom plate and the top plate on the shorter side. In this way, when the cylindrical frame bodies 4, 4, ... Are folded, four cylindrical frame bodies 4, 4, ... Are stored inside the bottom plate 2 and the top plate 3, and the bottom plate 2 and the top plate 3 are accommodated. It is convenient because it can be sandwiched between and, and the shape during transportation can be greatly reduced.

In the drawings, reference numeral “0” indicates a container for transportation from the outer periphery when a plurality of cylindrical frames 4, 4, ... Are provided between the bottom plate 2 and the top plate 3 to form a container for transportation. It is a groove for hanging a band to tie up, and "P" is a handle.

Next, with reference to FIG. 2, the operation of assembling the transportation container 1 will be described. In FIG. 2, one cylindrical frame body 4 is provided between the bottom plate 2 and the top plate 3, but the number of the cylindrical frame bodies 4 depends on the size of the contents to be stored. It may be selected appropriately and the inner volume of the transport container may be adjusted.

By fitting the connecting concave portions 14 and 14s and the connecting convex portions 13 and 13s, the bottom plate 2 and the top plate 3 and the cylindrical frame body 4 can be connected easily and reliably. In addition, at the time of this connection, for example, if the convex portion 11 of the bottom plate 2 and the concave portion 12s of the cylindrical frame body 4 are closely fitted into each other, as shown in FIGS. There is almost no gap between the outside and the outside, and even if there are many joints, it is possible to prevent the internal air from escaping and to prevent hot air from entering the inside from the outside. It is possible to complete the cold insulation function of the transport container 1.

After the articles are stored in the container 1 and transported, the tubular frame 4 is removed from the bottom plate 2 and the top plate 3, and as shown in FIG. , The cylindrical frame bodies 4, 4, ... Are folded, and the folded cylindrical frame bodies 4, 4, ... Are stored in the bottom plate 2 or the top plate 3, as shown in FIG. Four bodies 4 can be accommodated in the bottom plate 2 and the top plate 3, and the cylindrical frame bodies 4, 4 ...
