Description

[Detailed Description of the Invention] The present invention relates to a simple assembly type container, and more specifically, it can be assembled and disassembled easily and in a short time, and when returned, it can be disassembled into a smaller size, and
The present invention relates to a simple container that can withstand repeated use multiple times and is particularly suitable for storing and transporting powdery substances.

Containers that have traditionally been used for this type of purpose include kraft paper and carton boxes, but these have problems with strength, reusability, etc., and there are few containers that are especially suitable for powder and granular materials. .

In addition, bag-shaped containers made of synthetic resin, rubber, etc., such as flexible container bags, are often used for transporting powder and granular materials, but since the contents cannot be seen from the outside, such bag containers are difficult to carry in and out. They are inconvenient, difficult to fix, and therefore difficult to stack, requiring a large amount of storage space, and difficult to use as a substitute for a hopper or the like when filling contents.

Furthermore, it also has the disadvantage that the fixed parts at the loading and unloading ports are easily damaged.

The present invention improves these problems and can withstand repeated use multiple times, can be used as an alternative to tanks, hoppers, etc., and internal cleaning after use is easy or unnecessary.
We provide a simple assembly type container for powder and granular materials that is efficient in storage space, easy to dismantle after use, easy to pack into a small bulk, suitable for return shipping, and has a large economic effect. There is something to do.

Embodiments of the present invention will be described below based on the drawings.

The base 2 is made of a rectangular frame made of square pipes assembled into a square shape, and the bottom frame 6 is made of a square frame made of angle iron assembled in a square shape with one side serving as a side wall, and the bottom plate has an opening/closing door 10 inside. 8 are arranged in series, and an oval engagement hole 7 is provided laterally at each side end of each side wall of the bottom frame.

The engagement hole engages a protrusion 24 provided at the bottom of the side end metal frame 22 on the right side of the side plate 21 at right angles to the plate surface, thereby fixing the side plate.

Also, the inner bottom surface of the cross-sectional bottom frame, that is, the side plate edge receiving surface 9
needs to have a width that can accommodate the bottom of the side plate 21, and corresponds to the thickness of the side plate.

The bottom plate 8 is inclined downwardly toward the opening/closing door 10 in the center of the frame, and its upper edge is connected to the edge of the side plate edge receiving surface of the bottom frame by welding or the like.

By making the slope downward, the contents such as powder and granules can be smoothly discharged from the opening/closing door.

As the degree of inclination increases, it becomes easier to discharge the contents such as powder and granules, but at the same time, the pallet part becomes higher, which improves workability, storage efficiency, etc.
Difficulties arise in economic efficiency, etc.

In the simple container according to the present invention, the results of experiments using flour milling of synthetic resin etc. showed that
The opening/closing door 10, which preferably has an inclination angle of about .degree., under the above conditions, is an outlet for the contents such as powder and granules.

Various methods can be adopted as the opening/closing means.

For example, as shown in FIG. 3, hinges 11 are attached to the side edges of the bottom plate 8 and the opening/closing door in contact with the bottom plate 8 as shown in FIG. 13 to close the opening/closing door 10.

When discharging the contents, simply by removing the lever, the opening/closing door automatically closes due to the weight of the contents, and the contents are discharged into a predetermined tank or the like.

Although not shown, other shapes for the opening/closing door 10 may be a double door type in which the opening/closing door is divided into two parts, or grooves are provided at both ends of the opening/closing door, and shutter plates are fitted into the grooves. It can also be inserted to create a sliding door.

Furthermore, instead of the opening/closing door, a valve may be attached via a joint to discharge the powder.

The base 2 and the bottom frame 6 are fixed to each other with corner folds 3 at their four corners and intermediate beams 4 interposed between the corner folds to form a pallet part 1.

Although it can be used as a normal pallet with just the square fold 3, in this simple container intended for multiple use and storage in 9 stacks, any number of square girders 3 and 3 can be used between the square girders 3 and 3 to increase the strength. There are 4 digits.

The number of intermediate girders is preferably two in terms of strength, workability, and cost.

The height of the corner fold 3 and the middle girder 4 is the size of the pallet part 1,
It is determined by taking into account the degree of inclination of the bottom plate 8, etc., but there are restrictions from workability, storage efficiency, etc., but if it is too low, it will cause problems such as poor operability for carrying out contents, so 15Qm is determined.
m to about 350 mm is preferable.

A forklift, rope, etc. is inserted into the space created between the base 2 and the bottom frame 6, and the corner fold 3 and the middle girder 4 to transport the wooden container. At that time, the forklift's claws etc. come into direct contact with the bottom plate 8, causing the Because there is a risk of damaging the bottom plate,
As shown in FIG. 3, FIG. 3, and FIG. 4, which is a vertical cross-sectional view passing through the center of the pallet part, a protection plate 5 is provided.

The protection plate 5 has side end plates in which both ends of a horizontal plate are bent at right angles, and the outer side end plate is connected to the edge of the lateral bottom frame, the corner fold and the middle girder, and the inner side end plate is bent at right angles. is the middle girder 4 on the front and back
Each is fixed by welding etc. to protect the bottom plate, and
It also serves as reinforcement for the pallet section.

The side plate 21 is a square or rectangular square plate whose bottom length and plate thickness are large enough to be placed on the bottom frame, and a U-shaped upper metal frame 23 is provided at the upper end to protect the edge. A U-shaped side end metal frame 22 is fitted on both ends to protect the side ends.

At the bottom of one side of the side end metal frame, the one on the right side in the drawing, a protrusion 24 is protruded at a position that can be engaged with a circumferential hole 7 drilled in the bottom frame 6, perpendicular to the plate surface. When the side plate is erected on the bottom frame, the protrusions are engaged with the retaining holes to prevent the side plate from coming off the bottom frame.

The internal dimensions of the bottom frame are made slightly larger than the sum of the horizontal length and thickness of the side panels.

To assemble the container, fit the protrusions 24 of the first side plate into the engagement holes 7 of the bottom frame, and the longitudinal end surface of the side end metal frame on the side without protrusions comes into contact with the opposite wall of the bottom frame. The side plate is erected on the side plate edge receiving surface 9 as shown in FIG.

Insert the protrusions of the second and third side plates into the corresponding retaining holes, fit between the inner surface of the side end metal frame of the existing side plate and the inner wall of the side of the bottom frame, and then erect.

The fourth side plate is erected by taking advantage of the fact that the retaining hole 7 has a horizontally long oval shape.

That is, the side end metal frame of the fourth side plate is fitted into the gap formed between the long flat end face of the side end metal frame of the already installed side plate and the inner wall of the bottom frame opposite to the end face. While applying the protrusions of the side plate to the engagement holes, insert the fourth side plate so that the longitudinal end surface of the other side end metal frame of the side plate is in contact with the inner surface of the existing third side end metal frame. While shifting, the surface of the side plate may be brought into contact with the inner wall of the bottom frame.

Objects to be transported are accommodated in a rectangular portion with these side plates as outer walls.

The lid body 25 is formed by fixing a plate body on a crosspiece 26, and is placed on the upper end of the side plate 21 assembled in a square shape.

Although the lid 25 is not an essential component in the present invention, it is preferable to place it in order to protect the transported object.

The side plate 21 is placed inside the bottom frame 6 of the pallet part 1, and the protrusions 24
The container of the present invention can be used simply by fitting the side plates into the engagement holes 7, assembling the side plates into a rectangular shape, and covering the lid body 25. However, depending on the contents to be filled and the transportation method, the side plates may expand outward. To prevent this, it is possible to wrap a band or the like around the rectangular side plates and tighten them. Figures 5 and 6 are used to measure the
The fastener shown in FIG. 5, which preferably shows the embodiment shown in the drawings, has a sleeve 36 fixed on the plate surface side of the metal frame 23 at the upper end of the side plate, and consists of rods 37A and 37B, the tips of which are bent at right angles. A U-shaped lever 37 is inserted into the sleeve in advance, and after assembling the side plate 21, the lever is rotated in the direction of the arrow from the dotted line position in the figure to hook onto the adjacent side plate, and the lever is hooked to the adjacent side plate. This is to prevent the spread of the disease.

The fastener shown in FIG. 6 fixes latching tools 34A and 34B at positions corresponding to the upper end metal plate of each adjacent side plate, and each latching tool is bent at a right angle in the center and attached to both sides. The insertion blade of the latching tool 35 having a hanging insertion blade can be inserted.

After assembling the side plate, each insertion blade of the latching tool is inserted into the respective latched tool to prevent the side plate from expanding.

As explained above, the easy-to-assemble container according to the present invention is easy to assemble, has good storage efficiency, can be used multiple times, and is highly economical. Since the side plate dimensions are smaller than the internal dimensions of the bottom frame, it can be packed into a small volume by simply stacking four side plates in the bottom frame, stacking the lid, and placing it on top. It is convenient and has effects such as being very easy to clean.
