Description

Detailed Description of the Invention (Field of Industrial Application) The present invention relates to a packing material for an ink can and a method for preventing ink from drying inside the can. The present invention relates to a packing material that prevents ink from adhering and drying and solidifying, and a method for preventing ink from drying inside a can.

(Prior Art) Conventionally, offset ink or base ink for offset ink absorbs oxygen in the air and dries and solidifies, so measures are taken to prevent it from drying out when stored.

For example, in the case of small ink cans such as 1 kg cans and 5 kg cans, a film is placed on the surface of the ink inside the can to block air and then sealed with a lid. Similar measures are also taken for large cans such as drums.

(Problem to be solved by the invention) - In storing ink as described above, there is no major problem if the ink is small, but if the ink is large such as a drum, moving the drum can is difficult. In this process, the ink inside flows and the ink 3 adheres to the inner wall of the upper part of the drum 2, as shown in FIG. Ink attached like this 3
It is easy to dry and solidify, and if this dry solidified product is mixed into the ink, various troubles will occur during printing. To this end, conventionally, as shown in the second figure, an inner lid 5 is placed on the surface of the ink 3 covered with a film 4 to prevent the ink 3 from flowing.

However, even if such an inner lid is inserted, the above-mentioned problem will not be solved by the henchman because the inner lid will flow together with the ink.

As a result of intensive research to solve these problems, the inventor of the tree invented a ring-shaped ink can that suppresses the film stretched on the surface of the ink inside the can wall, without using an inner lid as in the conventional technology. It has been found that the above-mentioned problems of the prior art can be solved by using the packing material of the present invention.

(Means for solving the problem) In other words, what is the present invention? The first invention is a packing material for an ink can, which has an outer diameter that closely fits the inner diameter of the ink can, is made of an elastic material, and is ring-shaped. The invention involves filling ink, tightly covering the surface of the ink with a drying prevention film, applying a ring-shaped packing material made of an elastic material to the outer diameter of the ink can that closely contacts the inner diameter of the ink can, and pressing the film L on the inner wall of the can. This is a method for preventing ink from drying inside a can, which is characterized by attaching the can so that the ink can dry out.

(Example) Next, the present invention will be described in more detail with reference to oval drawings showing preferred embodiments of the present invention.

FIG. 3 is a diagram showing the entire ink can packing material 1 of the present invention, and FIG. 4 is a diagram schematically showing the method of the present invention.

Referring to FIGS. 1 and 2, the ink can packing material l shown in FIG. It has an outer diameter that is approximately equal to the inner diameter of the ink 2. The packing material 1 is preferably made of a material having a certain degree of elasticity, such as rubber, plastic, or metal, so that it can be easily attached and detached. The shape may be any ring shape as long as it fits closely to the inner wall of the can, but a preferred shape has a thickness of about 2 to 1 OIII layer and a width of about 2.5 cm to 20 cm. With such a shape, it is possible to most efficiently prevent the ink 3 from adhering to the inner wall of the drum 2 due to its flow.

Such a packing material l for ink cans of the present invention has a second
As shown in the figure, after a film 4 for preventing drying is brought into close contact with the surface of the ink in the ink can 2 containing the ink 3, the end of the film 4 is pressed against the inner wall of the ink 2. By attaching the packing material 1 in this way, even if the ink 3 inside flows when the ink 2 is moved, it is possible to prevent the ink 3 from adhering to the inner upper wall of the ink 2 can. Furthermore, even if the ink 3 in the ink can 2 expands or contracts due to temperature changes, the central part of the packing material 1 is covered with the flexible film 4, so it can follow the expansion and contraction of the ink. So no problems will occur.

(Function/Effect) According to the present invention, even if the ink can is tilted when handling the ink can, the ink in the ink can does not adhere to the upper part of the inner wall of the can, so that the ink remains in the ink. It is possible to prevent harmful dry solidified substances from being mixed in.
