(Prior Art) Conventionally, a storage container is cut into a certain shape, and a sheet of paper such as cardboard that is pre-folded is assembled on site at the time of use, or a storage container that has been preassembled is used. It was used in the assembled state. However, when assembling the storage container at the time of use, the work is time-consuming and troublesome, and when using the storage container pre-assembled, it is bulky and inconvenient for transportation and storage.

Therefore, there is a hexagonal assembly container 100 as shown in FIG. 14 as a structure in which the storage container is assembled and can be folded into two as it is.

In this conventional assembly container 100, six standing walls 121 to 126 are connected to each other via a fold line to form a peripheral wall 101, and the bottom edges of a pair of standing walls 123, 126 facing each other through the fold lines 133, 136. The erection plates 143 and 146 are connected to each other, and the erection plates 143 and 146 facing each other are connected to each other with a folding line (not shown) as a boundary.

Then, from the bottom edges of the pair of standing upright walls 122, 125 through the fold lines 132, 135, the substantially V-shaped notches 142A, 14 are formed at the tips.
Engagement plates 142 and 145, which are formed with 5A and are provided with folding lines (not shown) for folding the assembled container 100 in two in correspondence with the folding lines (not shown) of the installation plates 143 and 146, are connected. Is made.

Further, overlapping plates 141 and 144 that overlap with the engaging plates 142 and 145 are connected from the bottom edges of the pair of standing upright walls 121 and 124 via fold lines 131 and 134.

Then, the pair of overlapping overlapping plates 141 and 144 and the engaging plate 1
42 and 145 are configured to engage on the construction plates 143 and 146 during assembly.

This assembled container 100 has the above-mentioned configuration and is constructed from the AA line to the peripheral wall 1
When 01 is folded in two, a pair of overlapping superposed pairs 141 and 144, engagement plates 142 and 145, and installation plates 143 and 146 are folded lines (not shown).
It is possible to fold the assembly container 100 into two folds and fold it up and down.

(Problems to be Solved by the Invention) The conventional foldable assembly container 100 is the assembly container 1
When the bottom of 00 is lifted from the bottom with a finger and an upward force is applied, the pair of overlapping overlapping plates 141, 144, the engaging plates 142, 145, and the erection plates 143, 146 bend and stand up at the folding line (not shown), and easily stand up. The assembled state is broken.

As described above, the conventional assembled container 100 has a problem that the bottom of the assembled container is weak against an upward force and thus is not easy to use.

Also, a pair of overlapping overlapping plates 141 and 144 and engaging plates 142 and 145
Not only is the state of being engaged with each other not aesthetically pleasing as a container, but there is also the problem that it is difficult to store the stored items if the bottom surface is uneven as described above. Therefore, the assembled container 100
In the case of using, a storage container (not shown) made of a synthetic resin, which is slightly smaller than this assembly container, must be fitted in and used.

The present invention has been made to solve such a problem, and in a state where the storage container is assembled, it can be folded in two as it is, and the bottom part is strong against the upward force, which is easy to use.
It is an object of the present invention to provide an assembled container that is aesthetically pleasing and that allows easy storage of stored items.

(Means for Solving the Problems) In the assembled container according to the present invention, six standing walls are connected through fold lines, and bottom plates of the six standing walls are connected through fold lines, respectively. In the hexagonal assembly container, a pair of third standing walls and a sixth standing wall that are opposed to each other of the assembly container are connected to each other by a fold line for folding the assembly container, and the installation plate is connected to the third standing wall. A folding line similar to the one described above is provided on one of the bending plates connected to the adjacent fourth standing wall, and the one folding plate is connected to the fifth standing wall adjacent to the sixth standing wall. Is provided on the upper surfaces of the pair of installation plates by connecting the first and second first walls adjacent to the sixth standing wall.
The other bending plate connected to the standing wall is provided with a folding line similar to the above, and the other bending plate is connected to the lower surface of the bottom plate connected to the second standing wall adjacent to the third standing wall. The bottom plate in contact with the bottom edges of the third to fifth standing walls and the fifth
The fold line between the upright wall and the sixth upright wall and the fold line between the first upright wall and the second upright wall are formed at least in a size to be connected with a substantially straight line, and the fold line is formed on the hexagonal container bottom formed by each of the bottom plates. The bottom plate is overlapped, and the bottom plate is folded in two with folding lines provided on the one erection plate and the pair of bending plates as a boundary.

Further, one or more locking projections are formed on the outer peripheral edge of the bottom plate of the assembly container, and a locking notch is formed at the bottom edge portion of the peripheral wall corresponding to the locking projections.

Further, a slit is provided at the bottom edge portion of the peripheral wall of the assembled container, and the outer peripheral edge portion of the bottom plate engages with the slit.

(Operation) In the present invention, a pair of erection plates are connected to each other with a folding line for folding the assembled container as a boundary, and one bending plate and the overlapping plate are connected to each other and provided on the upper surfaces of the pair of erection plates. The other bent plate is connected to the lower surface of the face plate, the bottom plate is in contact with the bottom edges of the third to fifth standing walls, and the crease line between the fifth standing wall and the sixth standing wall and the first standing wall and the second standing wall. Since the fold lines are formed at least in a size that connects them in a substantially straight line, and the bottom plate is overlaid on the hexagonal container bottom formed by each of the bottom plates, an upward force is applied to the bottom of the assembled container. However, the force against this works and suppresses the standing of each bottom plate.

Further, one or more locking projections are formed on the outer peripheral edge of the bottom plate, and locking notches are formed at the bottom edge portion of the peripheral wall corresponding to the locking projections to lock these locking projections. By engaging the notches, even if an upward force is applied to the bottom portion of the assembled container, the force against this acts more reliably and suppresses the standing of the bottom plate, the erection plate, and the like.

Further, since a slit is provided on the peripheral wall of the assembled container, the outer peripheral edge portion of the bottom plate is formed so as to engage with the slit,
By engaging the outer peripheral edge portion of the bottom plate with the slit, the standing of the bottom plate, the erection plate, etc. is surely suppressed against the upward force on the bottom of the assembled container.
