Conventionally, in this type of vacuum insulation panel, a filler made of granules or powder is stored in a breathable kraft paper bag, which is then lightly compression-molded into a predetermined shape, and then made of aluminum-deposited plastic. The laminated film container is placed inside a vacuum sealed container equipped with a heat sealer, and the air inside the vacuum sealed container is then sealed until a predetermined degree of vacuum is achieved. By discharging the liquid to the outside, the laminate film container placed inside the vacuum sealed container is evacuated. After evacuation, the opening of the laminate film container is sealed airtight by thermocompression bonding with a heat sealer.

(Problems with the Background Art) However, in such a conventional configuration, a kraft paper bag is used to prevent the filling made of granules or powder from being discharged to the outside during vacuum evacuation. This has the drawback of increasing the number of parts and increasing costs. Furthermore, since the gas contained in the kraft paper bag is released during vacuuming, the vacuuming process takes a long time, resulting in poor productivity.

That is, in the vacuuming process shown in FIG.
The exhaust cylinder 5 is inserted into the cylindrical opening 4 of the jig 6.
Supported by Now, the exhaust cylinder 5 has an outer cylinder part 7.
It has a double cylindrical shape with an inner cylindrical part 8 that is movable relative to the outer cylindrical part 7, and has elasticity fitted into an annular groove 7a formed inside the outer cylindrical part 7. O-ring 9 (
(see Fig. 2), the airtightness between the outer cylinder part 7 and the inner cylinder part 8 is maintained, and the inner cylinder part 8 is inserted into the opening 4 in a state protruding from the outer cylinder part 7, and the inner cylinder part An annular backing 10 made of, for example, silicone rubber (see FIG. 3) and a jig 11 fitted into an annular groove 88 formed on the outside of the part 8 ensure the airtightness of the gate between the inside and outside of the outer shell 2. is held,
The air within the outer shell 2 is exhausted to the outside through the inner cylindrical portion 8, thereby evacuating the inside of the outer shell 2. As shown in FIG. 4, a filter 12 made of, for example, kraft paper is attached to the tip of the inner cylindrical portion 8, thereby preventing the filling material 3 from being discharged to the outside during evacuation. Following the evacuation step, a thermocompression sealing step shown in FIG. 1(b) is performed.

In this thermocompression sealing process, the jig 11 is removed, the inner cylinder part 8 is moved toward the outer cylinder part 7 (leftward in FIG. 1(b)), and the opening 4 is thermocompression-bonded with a heat sealer 13. Thus, the vacuum state within the outer shell 2 is hermetically sealed. After this, jig 6
The vacuum insulation panel 1 is formed by removing the panel and cutting the thermocompression bonded portion.

According to this embodiment, the following effects can be obtained. That is, since the filter 12 prevents the filling material 3 from being discharged to the outside during the vacuuming process of the outer shell 2, a raft paper bag unlike the conventional method is no longer necessary.
As a result, the number of parts can be reduced, and costs can be reduced accordingly.In addition, there is no gas generated from the kraft paper bag during vacuuming (conventionally, gas is generated from the kraft paper bag when vacuuming), and the vacuuming time can be shortened, improving productivity. In this case, the filter 12 is also made of kraft paper, but the amount of gas released from it is extremely small, and moreover, it is continuously used during each vacuuming process and is degassed. , there is no problem at all.Also, since the exhaust cylinder 5 is configured in a double cylinder shape with an outer cylinder part 7 and an inner cylinder part 8 that is movable with respect to the outer cylinder part 7, the inner cylinder part 8 is connected to the outer cylinder. The vacuum drawing process and the thermocompression bonding and sealing process can be easily carried out successively by a simple operation of moving in the direction of the part 7.

(Effects of the Invention) As is clear from the above description, the present invention includes a double cylindrical exhaust cylinder having an outer cylinder part and an inner cylinder part, which is inserted into the opening of the outer shell, and a filter is attached to the tip. Since the inside of the outer shell is evacuated through the inner cylindrical part, the number of parts can be reduced and costs can be reduced, and the evacuation time can be shortened and productivity can be improved. It has a great effect.
