Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a can container having a multi-

The present invention relates to a can container having a stackable structure capable of improving the stacking and stacking properties of a packaging can to completely prevent the collapse or collapse of a packaging container for packing a liquid or gel- And a method for manufacturing the can container.

The can container was first invented in 1679 by one of the inventors of France, Toni Papy, who invented the "steam pot," and the British Peter Durand considered that iron can containers would be more effective, It was invented canned in the 1860s, made of thinner steel plates, and was made using several kinds of tinned can from 1819 to 1901, .

In general, the can container is formed by forming a body of a metal plate made of an electro-tin plated plate, forming upper and lower plates for sealing both ends of the body, and then sealing the upper and lower plates by a banding operation between the upper and lower plates Is manufactured.

That is, the present invention provides a method of manufacturing a tin-plated steel sheet, comprising: a printing process of metal-printing a desired design on a tin-plated steel sheet; a cutting process of cutting the printed tin-plated steel sheet to an appropriate size; A body folding step of folding each blank into a square shape for welding the blank to which the panel ring has been completed, and a step of folding the can finished each folding process by welding with a copper wire A lining process in which the upper and lower ends of the upper and lower ends are joined together by a compounding process for sealing the upper and lower plates respectively coupled to the upper and lower ends of the body, A test to check whether leaks are occurred by filling the air to prevent leakage of seamed finished products, It is common to manufacture the finished can through a process, a packaging process for bundling and packaging in a suitable number, and a loading process for loading the canned container.

11, the tin-plated steel sheet is folded and folded to form a body body portion 3 in a flattened state in a flat state, and the upper and lower plates 10 and 30, The canister 100 is provided with a discharge port 15 for discharging the contents of the can container 100 to the outside and use the can container 100 as a center, It is a typical structure of the can container 100 to form the handle 14 for facilitating transportation of the can.

It is common that such a can container is packed at the time of manufacturing or after the completion of the manufacturing process, filled with the contents in a sealed state, and stored in a stacked state in a market such as a large store or the like.

However, when a conventional can container is to be stacked, the can container is simply fitted between the rim of the upper plate and the rim of the lower plate. When the can container is stacked by a small impact force from the outside Which may lead to a safety accident in which the operator is injured, or that there is a leakage of contents due to breakage of the can container. When the content of the can container is broken and the content of the can container is the kind of the poisonous substance, the damage is significant.

Therefore, when the contents are filled in the conventional can container and then laminated, the tendency to avoid the high loading and to load the low can be large, and the storage capacity is largely occupied. Therefore, It has been pointed out that the storage of containers is virtually impossible.

In addition, even when laminated at the time of shipment without storing the contents, when the laminated material is stacked at a high level, the laminated state of the unstable state easily causes a small impact from the outside, The utilization time of the loading place is not maximized as described above. In addition, since the work cycle time required to move or discharge the can container in the empty state stacked up to a certain extent in the packaging step to another place is shortened, Which is a cause of deterioration of the productivity due to an increase in the amount of water.

SUMMARY OF THE INVENTION Accordingly, the present invention has been made keeping in mind the above problems occurring in the prior art, and it is an object of the present invention to provide a can container for filling, storing and distributing liquid or gel- A lower plate having lower plate protrusions to be fitted in the recesses of the upper plate protrusions is formed at each of the upper and lower ends of one can container so that when the finished can container is stacked, The can container top plate can be stacked and stacked in a shape to be fitted in a groove formed in the inside of the top plate projection of the top plate of the can container so that the stacked can containers can be stacked securely and stably so as not to fall down due to a light impact from the outside To prevent safety accidents and damage to the product, and to improve the reliability of the product. There.

In addition, the present invention is intended to enable stacking of can containers with a high degree of compactness even in a narrow place, and to shorten the work cycle time by a transfer tray to another place after a certain degree of loading, There is a purpose.

Another object of the present invention is to maximize the utilization of the nipping place by facilitating the storage of the contents by stacking and stacking multiple layers on a general large market or the like in a state of being filled with contents so as to maintain a stable state even on display.
