Description

[Detailed Description of the Invention] The present invention relates to a large cylindrical container that can be used for multiple purposes such as transporting, storing, and stirring products in industry, agriculture, and fisheries.

For example, when manufacturing a large cylindrical container for multi-purpose use, if the cylindrical container is made only of metal, it will have excellent mechanical strength, but it will be physically unstable and rust will occur. The disadvantage is that the contents deteriorate.

Furthermore, manufacturing the cylindrical container only from synthetic resin poses problems in terms of cost and safety.

Therefore, the present invention is a metal outer container with excellent mechanical strength,
By constructing an inner container made of physically and chemically stable synthetic resin, the present invention not only solves the above-mentioned drawbacks, but also provides a large cylindrical container with excellent durability.

An embodiment of the present invention will be described in detail below with reference to the drawings.

In FIGS. 1 to 3, reference numeral 1 denotes a large cylindrical container, which is composed of an outer container 2 made of metal, an inner container 3 made of synthetic resin, and a lid 4.

The above metal outer container 2 is formed by cutting a cylindrical iron drum at the longitudinally intermediate portion.

The opening periphery 2a at the upper end of the metal outer container 2 is curled outward to form a reinforcing portion 2b having a loop-shaped cross section.

Further, positions 2c, 2 corresponding to each other in the radial direction of the opening periphery 2a
Through-holes 2e, 2e, 2f for hanging are provided at C and intermediate position 2d, respectively, and each through-hole (L2e, 2e, 2)
A U-shaped metal fitting 2h is integrally welded to f for reinforcement.

On the other hand, the lower end peripheral edge 2g is divided into three parts by stacking legs 5, each having an angle member 5a at the lower end. 5 are welded so that they can be stacked vertically in large numbers.

and each leg5. 5. A loop-shaped hook 6 is fixed to the outer surface of the container 5, and by hooking a hook such as a crane onto the hook 6, the metal outer container can be tilted or reversed.

The internal resin container 3 is made of polyethylene resin, has approximately the same shape as the metal outer container 2, is large enough to be loaded into the metal outer container 2, and has a thin wall, and has an opening at the upper end. A flange portion 3b having an arcuate cross section that matches the upper surface of the reinforcing portion 2b is formed on the peripheral edge 3a.

In the above embodiment, leg 5. 5. 5 in three places, each leg 5. 5. Since hook 6 is attached to 5, no matter which leg's hook is lifted, the other two legs will be hung in two places.

This makes contact with the floor surface to maintain the stability of the entire container when it is tilted, ensuring that it does not sway horizontally and ensuring safe discharge of contents.

The lid 4 is formed from a metal outer lid 4a and a synthetic resin inner lid 4b.

The metal outer lid 4a is formed by curling the peripheral edge of an iron disc into an arc shape to form a locking collar 4a'.

The synthetic resin inner cover 4b is made of synthetic resin such as polyethylene or polypropylene, has substantially the same shape as the metal outer cover 4a, and is removably fitted into the inner surface of the metal outer cover 4a.

The locking flange 4b' of the synthetic resin inner lid 4b has a cross-sectional shape that matches the circumferential surface of the flange 3b of the synthetic resin inner container 3.

The large cylindrical container configured as described above has a metal outer container,
It consists of a synthetic resin inner container and has both high mechanical strength and excellent physical and chemical stability, so it can be used as a container for loading food or industrial parts, etc. in the industrial, agricultural and fisheries industries. It can be used in all directions outside.

In addition, since only the synthetic resin inner container can be removed from the container of this invention, not only can the surface in contact with the contents be cleaned quickly and easily, but even if the inner container is damaged, only the inner container can be replaced. And it's economical.

Furthermore, if a container as shown in FIG. 4 is used as the inner container, the stirring efficiency can be improved.

In particular, in the container of the present invention, the periphery of the opening of the metal outer container is curled to form a reinforcing portion with a loop-shaped cross section, thereby increasing the strength of the entire container.

Moreover, since a flange having an arcuate cross section that matches the top surface of the reinforcing part is formed on the periphery of the upper opening of the inner container made of synthetic resin, the sealing effect of this flange allows the outer container made of metal to be connected to the inner container made of synthetic resin. This not only prevents the liquid contents from entering between the metal container and the metal outer container and improves its durability, but also allows the flange to be used even when the lid is placed on the top. The lid body and the synthetic resin inner container have good adhesion and can be sealed tightly.

In addition, the upper part of the container has multiple through holes for hanging, so the container can be moved and the contents can be discharged, and the lower end has legs for stacking, so the upper opening can be used as a container. They can be inserted into the legs and stacked safely.
