SUMMARY OF THE INVENTION
In order to assemble a prefabricated container as described in JP-A-42657, one side wall is first erected with respect to the bottom wall, and the side wall adjacent to the side wall is supported by hand so as to maintain the upright posture. In addition, it is necessary to raise the shaft, engage the side wall that is first raised and supported by the hand, and then raise the remaining side walls sequentially to engage the adjacent side walls with each other.

[0004] As described above, in assembling this kind of assembling type container, the side walls that are erected with respect to the bottom wall are manually erected in an erect posture until at least the next adjacent side walls are erected and engaged with each other. Since the container must be continuously supported, aside from the case where the container is small, the larger the container, the more difficult it is for one person to perform the assembling work.

[0005] Therefore, an object of the present invention is to provide a container having a container in which at least one of the side walls which are hingedly connected to each side of the bottom wall by a hinge is held upright with respect to the bottom wall. An object of the present invention is to provide an assembling container that can be easily and quickly assembled by holding at least one side wall in an upright posture and sequentially connecting other side walls to the at least one side wall.

[0006]

According to a first aspect of the present invention, there is provided an assembling type container having a bottom wall having side walls connected to each side of a bottom wall by hinges so as to be capable of being turned upside down. And an adjacent side wall is engaged with each other to form a container, at least one side wall of the hinge is connected to a side of the bottom wall so as to be able to be turned upside down, and the side wall stands upright with respect to the bottom wall. And a locking mechanism for holding the lock.

[0007] Further, the assembling type container according to the present invention is configured such that the pair of side walls facing each other in the above configuration is held in an upright posture with respect to the bottom wall.

[0008] Further, the assembly type container according to the present invention comprises:
In any one of the above structures, the locking mechanism for holding the side wall in the upright posture with respect to the bottom wall is constituted by a detachable fitting projection and a fitting recess.

In the present invention, the opposing surfaces of the bottom wall and the side wall with the hinge interposed therebetween have inclined surfaces so that the side wall stands upright with respect to the bottom wall and abuts each other. It is possible to form a locking mechanism including the detachable fitting projection and the fitting recess.

Further, in the present invention, the latch comprising a fitting projection provided at the hinge-side end of the side wall and a fitting recess corresponding to the fitting projection provided at the hinge-side end of the bottom wall. A mechanism can be formed.

[0011]

FIG. 1 is an overall perspective view of an assembling type container according to an embodiment of the present invention, FIG. 2 is a plan view showing its expanded state, and FIG. 3 is a sectional view taken along the line BB of FIG. Perspective view, FIG.
5 is a cross-sectional view taken along the line AA in FIG. 2, FIG. 5 is a cross-sectional view corresponding to FIG. 4 in a state where the side wall is held in an upright posture with respect to the bottom wall, and FIG. FIG. 7 is a perspective view showing another embodiment corresponding to FIG.

The illustrated assembling type container comprises a bottom wall 1 and four side walls 3 (3a to 3d) which are connected to the four sides thereof by hinges 2 (2a to 2d) so as to be able to move up and down. The upright side walls 3 adjacent to each other are engaged and fixed by an engaging structure 4 to form a box-shaped container. The engagement structure 4 includes, for example, one latch and the other a latch receiver.

In this assembling type container, the bottom wall 1 and the side wall 3 have a hollow double-walled structure obtained by blow molding a thermoplastic resin. Side walls 3 on each side of bottom wall 1
Are formed by compressing and thinning the parison during blow molding. The hinge 2 is flush with the outer surfaces of the outer wall of the bottom wall 1 and the outer wall of the side wall 3.

The hinge 2a connecting one side of the bottom wall 1 and one side wall 3a is formed by opposing surfaces 5 and 6 sandwiching the hinge 2a of the bottom wall 1 and the side wall 3a with respect to the bottom wall 1. The side walls 3a are inclined so as to stand in a vertical posture and abut against each other. A fitting projection 7 is formed on the facing surface 5 of the bottom wall 1 and a fitting recess 8 is formed on the facing surface 6 of the side wall 3a.
When the side wall 3a stands upright with respect to the bottom wall 1, they are engaged with each other to constitute a locking mechanism 9 for holding the side wall 3a upright with respect to the bottom wall 1; When the side wall 3a is deployed at the time of disassembly, the fitting is released. The fitting projection 7 and the fitting recess 8 constituting the locking mechanism 9 may be provided in reverse on the bottom wall 1 and the side wall 3a. As shown in FIG. 7, the fitting projection 7 provided at the hinge-side end of the inner surface of the side wall 3a has tapered surfaces 10 on both side surfaces thereof.
The fitting recess 8 provided at the hinge-side end of the
May be provided. In this case, the fitting protrusion 7 is fitted into the fitting recess 8 by making the side wall 3a along the bottom wall 1 when standing upright in the vertical posture.

In the illustrated embodiment, a locking mechanism 9 is also provided at the hinges 2b to 2d of the bottom wall 1 and the other three side walls 3b to 3d, respectively. Also has the same configuration as the locking mechanism 9 provided between the bottom wall 1 and one side wall 3a.

In order to assemble the assembly type container according to the present invention, first, the four side walls 3a to 3d are erected in a vertical posture with respect to the bottom wall 1, and the four side walls 3a to 3d are located adjacent to each other. The container is constituted by being connected and held by the engagement structure 4.

By the way, the side walls 3a to 3d which stand upright with respect to the bottom wall 1 are respectively held in the upright position by the locking mechanism 9, so that even if the hands are released from the side walls 3a to 3d, they stand upright. Keep your posture. Therefore, the operation of connecting and holding the mutually adjacent portions of the four side walls 3a to 3d by the engagement structure 4 can be performed easily and quickly.

The present invention is not limited to the illustrated embodiment, but can be various other embodiments. That is,
In the illustrated embodiment, the bottom wall 1 and four side walls 3a to 3d
In the present invention, for example, only a locking mechanism for holding the side wall in an upright posture may be provided between the bottom wall and at least one side wall. The object of the invention can also be achieved by a configuration in which the pair of side walls is held in an upright posture with respect to the bottom wall.

In the apparatus provided with a locking mechanism for holding the side wall in an upright position between the bottom wall and at least one side wall, the one side wall is held in an upright position, and the other side wall is provided on the other side wall. Are sequentially connected, the container can be assembled easily and quickly.

In a configuration in which the pair of opposed side walls are held in an upright position with respect to the bottom wall, the pair of side walls are held in the upright position in the assembling process of the container. The container can be easily and stably assembled simply by being connected and held to the held side wall, and is particularly suitable for a large container to be assembled by a series of assembly operations.

[0021]

According to the present invention, at least one of the side walls which are hingedly connected to each side of the bottom wall by hinges is held upright with respect to the bottom wall, so that the container is In assembling, by holding at least one side wall in an upright posture and sequentially connecting the other side walls to the assembling container, it is possible to obtain an assembling container that can be easily and quickly assembled.
