Abstract

PROBLEM TO BE SOLVED: To provide an assembly-type container which can hold a rigid engaged state even if an engaging structure of side walls is simple. SOLUTION: An assembly-type container has side walls 2 which can be coupled so that they can stand and fall by a hinge on respective sides of a bottom wall. The side walls 2 are made to stand to have adjacent side walls 2 engaged with each other to structure a container. One of the adjacent side walls 2a is equipped with rod-like protrusions 5 making a pair while the other side wall 2b is equipped with an opening 6 for allowing the protrusions 5 to be fitted into. The side wall 2 having the opening 6 is equipped with a locking piece 11 to be pressure-fitted between the protrusions 5 making a pair to hold their interval.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an assembling plastic container having a bottom wall and a side wall which can be turned upside down with respect to the bottom wall.

[0002]

2. Description of the Related Art Conventionally, as a container used for storing and transporting articles, an assembling type container having a structure in which a side wall is freely expandable with respect to a bottom wall and assembled at the time of use is disclosed in Japanese Utility Model Application Laid-Open No. 6-42657. And Japanese Utility Model Laid-Open Publication No. 5-89230, and Japanese Utility Model Publication No. 63-15151 are known. In this type of assembling container, side walls are provided on each side of the bottom wall via hinges so that the side walls can be turned upside down, and the adjacent side walls are engaged to assemble the container.

[0003]

Incidentally, Japanese Utility Model Laid-Open No. 6-42657, Japanese Utility Model Laid-Open No. 5-89230, and
Alternatively, in the assembly type container described in Japanese Utility Model Publication No. 63-15151, ends of the upright side walls adjacent to each other are abutted, and a locking piece provided on one side wall is engaged with the other side wall. Although a fixing structure for engaging with the stop portion is formed, in such a fixing structure, the side wall may be disengaged when the container is transported, and the container may be disassembled during use. .

SUMMARY OF THE INVENTION It is an object of the present invention to provide an assembling container capable of maintaining a firm engagement state despite the simple structure of the side wall engagement.

[0005]

According to a first aspect of the present invention, there is provided an assembling container according to the present invention. An assembling container in which a side wall adjacent to each other is engaged to form a container, and a pair of bar-shaped projections is provided on one side wall adjacent to each other, and the bar-shaped protrusions are fitted and fixed to the other side wall. An opening is provided.

According to the present invention, a pair of bar-like projections on one side wall is inserted into an opening of the other side wall, and a lock piece for maintaining the distance between the pair of bar-like projections is press-fitted. It is preferred to do so.

FIG. 1 is an overall perspective view of an assembly type container according to an embodiment of the present invention, FIG. 2 is a perspective view showing an engagement structure portion of a side wall, and FIGS. FIG. 3 is a cross-sectional view showing an engagement procedure, and FIG. 3 is a cross-sectional view showing a state before a bar-shaped projection forming a pair of one side wall is inserted into an opening of the other side wall.
FIG. 5 is a cross-sectional view showing a mode in which a pair of bar-shaped projections of one side wall is inserted into an opening of the other side wall. FIG. 5 shows a mode in which a lock piece is press-fitted between the pair of bar-shaped projections from the mode of FIG. FIG. FIG. 6 is a perspective view of a main part showing another embodiment.

[0008] The assembled container according to the present invention has a bottom wall 1.
And a side wall 2 connected to each side thereof by a hinge, which is a thin-walled body that can be bent, so that the side wall 2 can be developed with respect to the bottom wall 1. Is a box-shaped container which is engaged and fixed by the engaging structure 3. Reference numeral 4 denotes a handle.

In the assembly type container according to the present invention, the bottom wall 1 and the side wall 2 have a hollow double-wall structure formed by blow-molding a thermoplastic resin.
Is formed by compressing and reducing the thickness of the parison during blow molding.

The engaging structure 3 for engaging the butting portion of the side walls 2 adjacent to each other standing upright with respect to the bottom wall 1 is provided with a pair of bar-shaped projections 5 on one of the side walls 2a adjacent to each other. An opening 6 into which the rod-shaped protrusion 5 is inserted is provided on the side wall 2a.
Is provided. The pair of bar-shaped projections 5 are cylindrical and have opposing surfaces formed on the flat portion 7, and further have end portions forming protruding fixing holding portions 8 with respect to the edge of the opening 6. The opening 6 has a long hole shape and has a notch 9 on the end face side. The other side wall 2b having the opening 6 has a lock piece 11 which can be turned upside down by a hinge 10.
Is provided. When the lock piece 11 is pushed down, the space between the pair of bar-shaped protrusions 5 is maintained and further press-fitted so as to enlarge the space between the pair of bar-shaped protrusions 5 to open the space between the pair of bar-shaped protrusions 5. To fix the engagement holding state.

In order to assemble the assembly type container according to the present invention, first, the side wall 2 is erected at right angles to the bottom wall 1,
A pair of bar-shaped projections 5 on one side wall 2 adjacent to each other is
If the rod-shaped projection 5 is inserted into the opening 6 of the other side wall 2b from the mode shown in FIG. 3 to the mode shown in FIG. 4, the fixed holding portion 8 on the end face side is engaged with both ends of the opening 6. In that case, the state is maintained. Next, as shown in FIG. 5, when the lock piece 11 is pushed down and pressed into the pair of bar-shaped projections 5 so as to maintain the interval, the paired bar-shaped projections 5 maintain the opposing interval, The engagement holding state with respect to the opening 6 is fixed, and a robust and reliable connection mode is maintained.

The container assembled as described above is
In order to disassemble in a developed state, first, the lock piece 11 is removed from between the pair of rod-shaped projections 5 and then the rod-shaped projections 5 may be removed from the opening 6, so that the disassembly operation can be performed easily and quickly.

In the assembled container according to the present invention, the pair of bar-shaped projections 5 provided on one side wall 2a adjacent to each other may be configured as shown in FIG.
The opening 6b is also configured in a form corresponding thereto. That is, in this other embodiment, a pair of bar-shaped protrusions is formed in a forked shape, and the opening 6 is formed to have an open shape on the end face side, and the partition bar 12 is provided in a bridging shape at the open portion. Configuration. In this embodiment, the forked rod-shaped projection 5 has elasticity in a direction in which the forked rod-shaped projection itself opens, and is engaged and held when inserted into the opening 6. A wedge member (not shown) can be driven into the opposed space 13 between the rod-shaped projections 5.

It should be noted that the present invention is not limited to the illustrated embodiments, but can be variously modified without departing from the technical scope described in the claims.
For example, the bottom plate and the side walls may have a single-wall structure having a required thickness instead of the hollow double-wall structure. Further, the shapes of the bar-shaped projections 5 and the openings 6 are not limited to those shown in the figures, and are arbitrary.

[0015]

According to the present invention, it is possible to obtain an assembling container capable of maintaining a firm engagement state despite the simple structure of the side wall engagement.
