Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a container having a maximum size of 3000 liters or less, that is, a medium-sized container used for transporting dangerous substances.

[0002]

2. Description of the Related Art A medium-sized container is a container having a maximum capacity of 3000 liters or less according to the UN Recommendation on the Transport of Dangerous Goods, and its constituent materials include an inner container made of metal, flexible, hard plastic, or plastic. , Fiberboard, wood, etc. are recognized. In addition, the Fire Service Act stipulates that medium-sized containers are "containers that have a structure that allows them to be handled by machines."

For example, a medium-sized container having a capacity of 1000 liters has a drum can 5 as compared to a 200 liter drum.
The product of this book can be stored in the space of 4 so that the storage cost and transportation cost can be reduced, and because each product is used exclusively, there is little product loss, which leads to environmental protection, and the working time is reduced to 1/5. It has advantages such as being able to reduce labor costs. Moreover, since the structure of the container is obligatory to mechanically load and unload with a forklift, etc., the loading and unloading time is short and the work safety is high. is there.

Currently available medium-sized containers include a medium-sized container with a plastic inner container and a metal medium-sized container. A medium-sized container with a plastic inner container, in which a blow-molded polyolefin container is housed in a metal basket-like frame, has a light weight, is resistant to acid / alkali products, and has a low manufacturing cost. Since it is used, it cannot be used as an organic solvent, etc., and its usage period is set at 5 years from the date of manufacture.

The conventional metal container is a stainless steel rectangular container in which a lower frame body having fork pockets and an upper frame body for stacking are welded and attached, and has corrosion resistance. Although there are few product restrictions and periodic inspections are required every two and a half years, it can be used for a longer period than plastic products.

However, in this metal container, the rectangular container itself is a structural body, and its outer periphery is exposed without being protected, so if it is bumped or tumbled during work. , The container could be damaged or the contents could leak. Further, since the rectangular container is weak against pressure change and the outer peripheral plate, the ceiling plate and the bottom plate are pressed to form ribs in order to maintain the strength as a structure, the manufacturing process is increased and the manufacturing cost is high. further,
In the conventional metal container, the fork pockets are provided only in two directions of the front surface (the discharge port side) and the back surface of the lower frame, which is inconvenient for the work.

[0007]

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a metal medium-sized container which is excellent in safety, easy to handle and low in manufacturing cost.

BEST MODE FOR CARRYING OUT THE INVENTION The medium-sized container of the present invention will be described below.
It will be described with reference to the accompanying drawings. 1 and 2 are a plan view and a front view showing an example of the medium-sized container of the present invention.
FIG. 2 is a sectional view taken along line AA of FIG. 1.

1 to 3, a metal cylindrical container 1 is shown.
Are accommodated inside the metal rectangular frame 2. The metal cylindrical container 1 made of a corrosion resistant metal such as stainless steel is
A manhole 3, a safety valve 4 and an air vent 5 are provided on the top thereof, and a discharge port 6 with a valve is provided on the bottom thereof. By making the container shape cylindrical as described above, the strength of the outer circumference becomes uniform and the reinforcing rib unlike the conventional rectangular container is not required, so that the manufacturing cost can be reduced. It is preferable that the container 1 has a large diameter to suppress its height. If the height of the container 1 is suppressed and the total height including the frame body 2 is set to 1.5 m or less, the containers can be stacked in two stages during storage in the warehouse to improve storage efficiency.

The metal rectangular frame 2 is composed of an upper frame member 7, a lower frame member 8 and leg members 9 attached to a vertical frame member 10 at four corners thereof. As shown in FIG. 1, the upper frame member 7 and the lower frame member 8 are approximately the same size as the outer periphery of the container 1 or slightly larger, and as shown in FIGS.
