2. Description of the Related Art Containers to be stored or transported tend to be an obstacle when they are not used if their shape does not change. For example, Japanese Utility Model Publication Sho 63-3932.
As proposed in Japanese Patent Laid-Open Publication No. 2004-163, the side wall plate is folded to reduce the volume when not in use.

In such a foldable container, each side wall plate can be assembled when necessary and can be folded when not in use, so that it is very convenient to use as a so-called returnable box, for example. Is. However, since the side wall plates are fixed to each other by a fixing member formed on a thin portion of the side wall plates, the strength when assembled is not sufficient. In other words, in order to fix each side wall plate, it is common to engage the protrusion protruding from one side wall plate into the engaging hole of the other side wall plate, and this is used at this time. Since it is difficult to form such a large protruding portion, it is not suitable as a container for storing heavy items such as industrial parts, frozen seafood, or agricultural products such as potatoes.

On the other hand, in the case of storing and carrying heavy objects as described above, it is not always necessary to use a container of a container type for carrying the heavy objects, but rather when assembled. In addition, it is required to have sufficient rigidity to maintain the box shape. Therefore, the present inventors have made it possible to make each member extremely compact and easy to handle by forming each member by an independent unit body before assembling. As a result of various investigations on how to make a container suitable for, the present invention was completed.

[0005]

The present invention has been made on the basis of the above circumstances, and the problem to be solved is to ensure sufficient rigidity at the time of assembly, particularly strength at the connecting portion. It is in. The object of the present invention is to propose an assembly container that can be made compact before assembly and can be made as strong as the integrally formed box after the assembly is completed. is there.

The second or first fitting part 40/30 into which the second fitting part 30/40 is fitted is formed.

[0007]

The operation of the assembling container 100 according to the present invention constructed as above will be described together with the mode of use thereof.

Before assembling the container 100, the side containers 10 and the bottom plate 20 are all plate-shaped before they are assembled. Naturally, the space is small. Therefore, it is very advantageous when the assembled container 100 itself is stored or displayed in a store, for example.

Further, in each of the side plates 10, for example, in the case of the embodiment shown in the drawings, a first fitting portion 30 is provided on the left end edge in the drawings of FIGS. 1 and 2, and a second fitting portion is provided on the right side of the drawings. Part 40
And the side plate 10 is formed as described above.
The same molding die is used to mold all four sheets. Further, when the ratio of the height of each side plate 10 to the lateral length in FIG. 1 is 1: 2, each bottom plate 20 can also be formed by the same molding die as the side plate 10. The details of this will be described in the following examples.

Further, in the embodiments described below, since the side plates 10 and the bottom plate 20 are formed in a hollow shape by the so-called blow molding method, the first and second fitting portions 30 at each edge thereof.・ 40 is hollow,
It has both predetermined elasticity and rigidity.
That is, the first and second fitting portions 30 and 40 have the flexibility necessary for connecting and fitting, and the elastic return force rigidity for ensuring the engagement after fitting. Have
In addition, since the plates 10 and 20 are hollow, even if the side plates 10 and the bottom plate 20 are bundled in the required number as the assembly container 100, the total weight thereof is extremely small. -ing

From the above, the assembly container 100
In the state before assembling as above, each side plate 10 and bottom plate 20 are plate-shaped, and as shown in the embodiment, if the ratio of the vertical length and the horizontal length of each plate is set to 1: 2, it is assembled. Side plate 10 and bottom plate 20 required for the container 100
Is very easy to store and is space-saving.

Now, in order to assemble the side plates 10 and the bottom plate 20 to form the container 100, the following may be carried out. That is, first, each side plate 10 is connected to each other by the first fitting portion 30 formed at one end thereof and the second fitting portion 40 formed at the other end thereof. This is done by forcibly fitting the second fitting portion 40 of the other side plate 10 to the first fitting portion 30 while keeping the second fitting portion 40 at a substantially right angle.

The fitting between them will be described in more detail. The fitting protrusion 33 on the first fitting portion 30 side is fitted into the fitting groove 4 on the second fitting portion 40 side.
The both side plates 10 are positioned so as to face the side plate 3, and the side plate 10 on the side having the fitting protrusion 33 to be fitted is forcibly pressed to the other side plate 10. Under normal conditions,
Protrusions 31 protruding on both sides (up and down) of the fitting protrusion 33
Although the first engaging projections 34 of the above do not come into contact with the respective second engaging projections 44 formed inside the fitting protruding portion 42,

Of course, in the embodiment described below, as shown in FIG. 5, inclined surfaces are formed in the portions of the first engaging protrusions 34 and the second engaging protrusions 44 that face each other. The above-mentioned fitting can be performed more reliably and easily.

Once the fitting is completed as described above, as shown in FIG. 5, the first engaging recess 35 and the second engaging protrusion 44 are formed on the back side of the first engaging protrusion 34. Since the second engagement recesses 45 are formed on the back side each having a right-angled surface, the first engagement protrusions 34 are formed in the second engagement recesses 45.
Inside, and the second engaging projections 44 enter the first engaging recesses 35, and the first engaging projections 34 and the second engaging projections 44 are completely engaged with each other. . At the same time, since the fitting protrusions 33 completely enter the fitting groove 43, the side plates 10 are connected while maintaining a right-angled state with each other, and this state is firmly maintained. In other words, the other side plate 10 which is orthogonal to one side plate 10 has sufficient strength particularly against pushing force and pulling force in the orthogonal direction.

By repeating the above process for each of the four side plates 10, one frame is formed, and the bottom plate 20 is provided on the bottom side of the frame.
Therefore, the first fitting portion 30 and the second fitting portion 40 for are exposed. (See FIG. 2) Then, for each bottom plate 20, the first fitting portion 30 and the second fitting portion 40 formed on the edge of each bottom plate 20 are used in the same manner as described above. Then, the side plates 10 are connected to each other.

As a result, as shown in FIG. 1 or 2, the assembly container 100 is completed.
In this embodiment, a protrusion 11 is formed on the upper edge of each side plate 10, and an engaging hole 12 for accommodating the protrusion 11 is formed on the lower edge of the side plate 10 corresponding to this protrusion 11. For this reason, for example, as shown in FIG.
Completed assembly container 10 with a frame consisting of only 0
It is possible to sequentially stack them above 0, and it is possible to obtain an assembled container 100 having a large volume by only having a predetermined side plate 10.

The assembled container 1 thus completed
00 is one in which each plate is completely connected to another plate by the first fitting portion 30 and the second fitting portion 40 formed on both ends of the plate, so that the assembly container 100 has an industrial structure therein. Even if heavy parts such as parts, frozen seafood, or agricultural products such as potatoes are stored, they are firmly held.
