[0002]

2. Description of the Related Art Various inks such as printing inks are generally packed in steel cans or other metal containers.

When the printing ink comes into contact with air (oxygen), a solidified film is formed on the surface by drying, and this is mixed into the ink, resulting in hitkey (crater-like printing unevenness).
And the like, which causes printing failure. Therefore, it is desirable to keep the printing ink filled in the container from coming into contact with air as much as possible.

Conventionally, in filling and packaging of this type of printing ink, a sulfuric acid paper or a synthetic resin film is placed on the stored ink so that the ink stored in a metal container or the like does not come into contact with air. Although various contrivances such as are performed, in the conventional packaging state of the container, a gap is generated between the paper or film and the inner surface of the container, and due to poor confidentiality, to prevent air contact. It is not perfect and has the drawback that the above problem cannot be solved.

[0012]

According to the printing ink filling and packaging method of the present invention described above, after the container body is filled with the ink to be packaged, a solvent of the same material as the ink is sprayed into the container body. In addition, it is possible to prevent the skin filling phenomenon of the ink filled by the solvent spraying, and to provide an appropriate partial pressure effect by evaporating the solvent in a sealed packaging state. In addition, since the upper space is filled with an inert gas that has been replaced with air, the hermetically sealed ink only comes into contact with the inert gas and does not come into contact with air. Therefore, it is possible to effectively prevent deterioration of the ink and generation of a dry film.

Moreover, since the sealing film is joined to the opening edge of the container body in a sealed state and sealed, and the lid is further fitted thereon, there is no possibility of damage to the sealing film.
In addition, the inert gas filled in the inside can be protected twice by the sealing property and the lid by the sealing film, keeping the airtightness of the container good and ensuring the inert gas filled in the container. Can hold.

In particular, in the case of the filling and packaging method of the second invention, a solvent of the same material as the filled ink is transferred to the container while the container body filled with the printing ink to be packed is sequentially and intermittently transferred. After spraying into the body, preventing the ink skinning phenomenon, and then passing through the gas replacement chamber,
Since the inert gas is blown into the space above the ink in the container in the gas replacement chamber, the air in the container body can be reliably replaced with the inert gas. Moreover, at the same time, the sealing film is brought into contact with the opening edge to close the upper opening, so that the inert gas blown as described above is securely held in the container main body, and the subsequent sealing process is performed. Can be sent,
By heat-sealing the sealing film, it is possible to reliably hold the inert gas sealed in the upper space in the container. Further, by fitting the lid on the subsequent side, the above-mentioned predetermined packed state can be obtained. Moreover, in this packaged state, similarly to the above, it is possible to effectively prevent the deterioration of the ink and the generation of a dry film.

According to the filling and packaging apparatus of the third invention,
The container body filled with the printing ink is sequentially and intermittently transferred by the transfer means, and a solvent of the same material as the ink is sprayed by the spray means provided in the middle of the transfer. While passing through the replacement chamber, an inert gas can be blown into the space above the ink from the gas blowing nozzle to be replaced with air. At the same time, a long film for sealing supplied from above to the gas replacement chamber is brought into contact with the edge of the opening by the film guide means provided thereafter so that the inert gas does not escape. The opening can be kept in a closed state, and can be sent to a sealing process by a subsequent sealing means in that state.
Therefore, the inert gas does not escape during the transfer.

Further, the sealing means in the sealing step is operated during the stop of the intermittent transfer so that the sealing film is heat-sealed to the opening edge of the container body, and further unnecessary portions around the film are cut by the trimming means. A lid can be fitted to the opening edge of the sealed container body.

As described above, by successively passing through each of these series of steps, a solvent of the same material is sprayed on the ink filled as described above, and an inert gas is further added to the filler. It is possible to efficiently obtain a filled and packed state enclosed in the upper space.

Further, according to the container for filling and packaging of the fourth invention, the container main body is formed mainly of paper, so that not only the disposal by incineration after use is possible, but also especially the paper material. The aluminum foil and the surface film layer made of synthetic resin are provided on the side surface, so even if the material is mainly made of paper, sufficient gas barrier properties can be secured by the aluminum foil and the surface film layer. The ink is well protected and the ink does not penetrate into the container itself.

Further, the cylindrical body portion and the bottom plate portion are folded inward at the lower end portion of the body portion, and a downwardly bent edge of the bottom plate portion is sandwiched between the folded portions so that the surface film layers are thermally fused to each other. Because it is joined by, it is excellent in the integration of both, while ensuring sufficient sealing performance at this joint,
The bottom plate portion is supported by the folded end of the body portion and is not excessively deformed, and can have sufficient shape-retaining strength to support the weight of the contents.

Further, since the upper end of the cylindrical body is curled outward to form an opening edge, the curling of the opening edge serves as a reinforcement, and this portion is used for sealing. The film can be easily and reliably heat-sealed, and a lid made of a synthetic resin molded article can be elastically fitted by utilizing the curled portion. Therefore, even those mainly made of paper can be suitably used as containers for storing printing ink.
