[0002]

2. Description of the Related Art Various inks such as printing inks and paints are generally filled and packaged in a steel can or other metal container.

When printing ink or the like comes into contact with air (oxygen), a solidified film is formed on the surface by drying, and this film is mixed in the ink to cause wicking (crater-like uneven printing).
There is a problem such as a cause of defective printing. Therefore, it is desirable to prevent the printing ink or the like filled in the container from coming into contact with air as much as possible.

Generally, in the filling and packaging of printing inks of this type, inks containing a sulfuric acid paper or a synthetic resin film are generally used so that the inks contained in a metal container do not come into contact with air. Although various measures such as placing it on the top have been made, in the conventional packaging state with a container, there is a gap between the paper or film and the inner surface of the container, and the airtightness can be prevented due to poor airtightness. However, there is a drawback that the above problems cannot be solved.

Further, since a container made of metal or the like cannot be incinerated, there is a problem that it is difficult to dispose of it as an industrial waste after use and the disposal process is troublesome.

The present invention has been made in view of the above, and it eliminates the air in the upper space of the printing ink or the like contained in the container and replaces it with an inert gas to seal and seal it with good airtightness. By packaging, the above problem due to air contact is solved, and the present invention is intended to provide such a filling and packaging method, and further, a filling and packaging apparatus capable of suitably implementing the method. It is provided.

Further, according to the present invention, a so-called paper can whose main body is made of a paper material is used as a container for filling and packaging the printing ink or the like, thereby facilitating incineration after use. In this case, there is no problem in terms of protection of the contents, strength, and safety, even in the case where the paper material is the main layer. It is intended to provide a container that can be suitably used.
