Description

[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a package for storing a metal powder paste such as aluminum powder.

[0002]

2. Description of the Related Art A metal powder paste is usually stored in a circular can formed of a tin plate or the like.

During the storage, air remaining in the canister or air entering the canister causes a reaction between the metal powder and oxygen and moisture, and the fatty acid and fatty acid salt contained in the metal powder paste. The reaction of oxygen and moisture also occurs.
Further, the solvent in the metal powder paste volatilizes.

[0004] These phenomena change the quality of the metal powder paste, and when used as a pigment, cause a change in wettability and a change in color tone.

[0005]

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a package in which deterioration of the metal powder paste does not occur.

[0006]

In order to solve the above problems, in the present invention, the inside of a sealable container containing a metal powder paste and the inside of a packaging bag containing this container are simultaneously evacuated , The container and the packaging bag were sealed together to form an airtight package.

[0007]

Since the inside of the container and the bag in which the container is packed are evacuated, air is removed from both the container and the bag.
Since the bags are sealed together, moisture does not enter.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the accompanying drawings.

FIG. 1 shows a container for storing a metal powder paste.

As shown in the figure, the container A includes a container body 10 formed of a tin plate or the like and a lid 20, and the container body 10
An edge winding 11 is provided on the periphery of the opening, and the outer edge of the lid receiving base 12 is wound and fixed together with the edge winding 11. The container body 10 contains a metal powder paste P
Is stored.

The lid 20 has a plug 21, and the outer wall of the plug 21 has a peripheral wall 1 of the lid receiving base 12 of the container body 10.
A packing 22 is provided to seal the container body 10 by press-fitting with the container body 3.

FIG. 2 shows an example of a packaging bag for storing the container A.

As shown in the figure, the packaging bag B is made of a synthetic resin film having a good barrier property, for example, in the form of a flat bag, one end of which is a heat sealing portion 30 and the other end of which is an opening 31. I have.

In the packaging bag B, a container A is stored as shown in FIG. At this time, the lid 20 is merely placed on the opening of the container body 10 and is not sealed.

Then, a vacuum is drawn from the opening 31 of the packaging bag B by the suction nozzle N. At this time, it is preferable that the opening 31 is appropriately squeezed and attached to the suction port of the nozzle N.

When the evacuation is completed, as shown in FIG. 4, the opening 31 is heat-sealed to form a heat-sealed portion 32, which is then sealed. 13 is crimped to seal the container body 10
You .

Thereafter, the packaging bag B is heat-shrinked as required, and is brought into close contact with the outer periphery of the container A as shown in FIG. Of course, in this case, it is necessary to use a heat-shrinkable synthetic resin film as the material of the packaging bag B.

[0018]

According to the present invention, as described above, the inside of the container storing the metal powder paste and the inside of the bag wrapping the container are the same.
Occasionally a vacuum is applied and the container and bag are sealed together , so that no air or moisture remains in the container and no air or moisture enters from the outside of the container. Can be prevented.
