DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lightweight, high-strength assembled container.

[0002]

2. Description of the Related Art Conventional containers used for packing articles are mostly boxes made of mesh such as wire mesh, wooden or veneer boxes, or iron boxes. Most of the materials are assembled by combining members made of wood, metal, and plastic materials, and these are mounted on a pallet for use. The container using the above-mentioned composite material is made robust in order to secure strength against a required load.

[0003] Therefore, when disposing, recycling or recycling, it is troublesome to disassemble, and at the same time, it requires a high degree of separation at the time of dismantling, and in particular, plastics made of inexpensive PVC resin are used. Therefore, dioxin may be generated during incineration, and there has been a major problem in separation, disposal, and recycling in this technical field.

[0004] On the other hand, by using PP (polypropylene, hereinafter abbreviated as PP) as the resin instead of the above-mentioned PVC, generation of dioxin can be prevented. It is effective for recycling and resource saving.

[0005] However, in the case of integral molding by injection molding in order to be made of PP, a sufficient thickness must be ensured to obtain the required strength, and the amount of resin used is large and the weight becomes heavy. Further, the production cost is extremely high in terms of the material, so that it has not been practically used.

[0006]

By the way, the applicant of the present invention has previously developed a panel made of PP called trade name "Damplate". This panel is a hollow core consisting of a number of parallel ribs and upper and lower liners, and is a lightweight and high-strength panel material.A container in which this hollow core panel is assembled in a box shape is lightweight, high-strength and inexpensive It has the advantage of using less resin, and is a container material suitable as a measure against dioxin.

However, when assembling this hollow core panel as a container, the structure of the material is similar to that of a conventional paper cardboard box. Combination with other materials such as rivets or other reinforcing materials such as reinforced frames at the corners is unavoidable.In addition, despite the high strength of the panel itself, insufficient bonding strength at the corners etc. It was not possible to avoid a decrease in the overall strength of the steel.

[0008] The above-mentioned problems are the same in the case of a PP foam plate material having relatively low expansion ratio and rigidity.

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and an object of the present invention is to make it easy to assemble and to improve the strength after assembling while enjoying the advantages of the packing material of a panel made of PP. In addition, the present invention provides an assemblable container made of PP which can be folded and compacted after use.

[0010]

In order to achieve the above object, the present invention provides a bottom plate, four side plates standing upright on four rounds of the bottom plate, a lower corner material having four corners of the bottom plate installed and fixed, An L-shaped outer wall portion integrally projecting from an upper corner portion of each lower corner material, a folding guide hole formed in an elongated shape along the vertical direction on both sides of the outer wall portion, and an outer wall portion An L-shaped vertical frame detachably erected on the inside of the frame, and an upper corner material having a substantially L-shaped planar shape formed with a groove for fitting the upper edge of the vertical frame and the upper edge corner of the side plate, Among the side plates, at least a pair of parallel side plates protrude from both ends of the side plate, and comprises a slide tilting shaft that penetrates a lower portion of the vertical frame and is pivotally and slidably connected to the folding guide hole. The lower part on both sides of the side plate can be turned on the outer wall part by the slide turning axis. Characterized in that it is obtained by sintering.

Therefore, in the assembly type container of the present invention, by assembling the respective parts according to a predetermined assembly procedure, the assembly can be performed without skill, and the bonding strength between the panels by the upper and lower corner materials and the vertical frame. Can be increased. After use, by folding each side plate on the bottom plate via the slide turning axis, it can be arranged in a flat shape and component loss can be prevented.

Further, in the present invention, at least one end of the vertical frame and a side edge of the side plate are formed with a hook-shaped engaging portion which is hooked and is flush with each other, so that the side edge of the side plate is formed. And the vertical frame can be securely connected.

Further, in the present invention, the upper corner material is
The fixed portion fixed to the upper edge of one side plate, and a fastener portion slidable along the upper edge of the other side plate and detachably connected to the fixed portion, are divided into two parts, At the time of hook-shaped engagement between the frame and the side plate, the fastener portion is moved to the hook-shaped engagement position to lock the engagement state, so that the side plate and the vertical frame can be more securely connected.

Still further, according to the present invention, the bottom plate and the side plates are fitted with a hollow core panel made of polypropylene comprising upper and lower liners integrally formed on both sides of a plurality of ribs, and around the hollow core panel. By having a reinforcing edge frame consisting of an extruded body to be combined,
Light weight and high strength can be achieved.

Further, in the present invention, a polypropylene resin rivet or clip is used as a means for connecting the lower corner material to the bottom plate and a means for connecting the upper corner material to the vertical frame. And there is no separation problem at the time of recycling, and no dangerous dioxin is generated during incineration.

FIG. 9 shows a case where the casters 21 are arranged at the corners of the bottom surface of the container 20 described above. In this case,
It is suitable for use in moving the container 20 on the floor. In order to allow the casters 21 to be mounted, a mounting hole is formed in advance in the center of the lower surface of the substrate 1a in the lower corner member 1, or mounting using bolt holes can be performed.

The caster 21 is an example, and a pallet for transporting a fork, a lid for an opening, and the like can be provided. In addition, addition according to various options is possible.

The containers 20 described above can be used alone for transportation as shown in FIG. 10 (a), or can be used by stacking many containers as shown in FIG. 10 (b). In this case, since the rising pieces 2b of the upper corner material 2 support the lower four corners of the container 20 stacked on the upper side in a state surrounding the lower corners, the stacking can be stably performed even when stacked in multiple stages, and there is a possibility of collapse of the load. Absent.

After use, as shown in FIG.
Each side plate 5b can be folded inward and installed on the bottom plate 5a. In this case, it becomes the height of the outer wall 1a of the lower corner material 1,
The package after transportation of goods can be stored compactly.

FIG. 11 shows the folding procedure. First, the fastener portion 11 of the upper corner member 2 is removed from the fixing portion 10 and moved to an appropriate position. Then, as shown in FIG. 7A, one side plate 5b is folded with the hinge pin 16 as a base point, and The side plate 5b is similarly folded.

At this time, the hinge point differs depending on the thickness of the side plate 5b folded first.
b may be pulled up slightly and then folded.

Then, the other side plate 5b is slid upward by the thickness of the adjacent side plate 5b folded up along the guide hole 1e, and further rotated inward at that position. If the same operation is performed on the facing side plate 5b and the side plate 5b is folded, the storage state shown in FIG.

In this embodiment, an example in which all the side plates 5b are turned inward and folded is shown.
6 can be pulled out from the lower corner member 1 and the deformed vertical frame 3, so that the hinge pin guide 15 does not necessarily rotate the hinge pin 1 so that the hinge pin 1 can be pulled out from the hinge pin guide 15.
6, the side plate 5b may be pulled out and stored as it is on the inside.

In the working mode described above, the fastener 1
1 can be sequentially folded by pulling it out from the fixing portion 10, and furthermore, since there is no attachment / detachment of the parts and no loss of the parts due to the detachment, they can be folded and stored without worrying about their storage. In reassembly, the original box shape can be easily restored by the reverse procedure.

[0059]

As is apparent from the above description, the assembled container according to the present invention has the following advantages.

It is a foldable and unfoldable type, and can flatten the package after transportation of goods, and does not involve the detachment of parts at the time of folding, so that parts are not lost and parts management is easy.

Except for some bolt joints, even if all parts are made of PP, including clips, or even if only the frame is made of aluminum, it can be freely inserted into and removed from the panel. For example, since it can be easily disassembled into various parts, the separation process at the time of disposal and recycling is extremely simple, and there is no possibility of generating dioxin even during incineration.

Anyone can easily assemble the assembly specifications without using special tools. In addition, this makes it possible to compactly assemble each member as a semi-finished product, not as a finished product, and then ship and sell the product.

It is made of PP and has sufficient strength and rigidity, but it is lightweight and uses a small amount of resin, which is an advantage of the panel material itself, can be manufactured at low cost, and has sufficient strength in corners and the like. The overall strength is also improved.
