。A conventional vacuum insulation material is shown in Fig. 4. 1' is a powder vacuum insulation material. First, a powder 2' such as perlite, which has been dried to a moisture content of 0.3% or less in a dryer, is made of paper, cloth, etc. for ventilation. Fill the plastic inner bag 3' and open it to prevent the powder 2 from leaking.
] After sealing the end surface, the inner bag 3' is placed in a bag 4' made of metal-plastic laminate film, etc., which has been sealed on three sides in advance, and after vacuum degassing in a vacuum packaging machine, the open end surface 5 is sealed. ' was manufactured by heat-sealing. However, this method requires a large number of man-hours as it requires the inner bag 3'.
Further, the powder absorbed moisture while being filled into the inner bag 3' taken out from the dryer, and as a result, it took a long time to reach a high vacuum, making production difficult as a whole.

のである。The present invention is a bag made of a metal-plastic laminate film, etc., and the opening end surface thereof is made of a flexible plastic foam, etc., which has air permeability in advance and can prevent powder from scattering outside the bag. By installing a filter consisting of the following, the above-mentioned conventional drawbacks can be solved.
以下本発明の一実施例について第１図〜第３図を参考に

A filter 6 made of a breathable plastic soft foam is attached to the inside of the bag 3 from the opening 4 with double-sided tape or adhesive, leaving a portion of the opening 4 open. 6 is a heat-sealing type located outside the filter 6.

。A container-shaped mold 7 that presses the bag 3 after filling the bag 3 with the powder 2 taken out from the dryer through the remaining amount opening 4.
, 8. One of the molds 7 is fixed, and the other mold 8 is movable up and down. The sides of the opening 4 of the bag 3 of the molds 7 and 8 are close to each other so as to press the outer side of the filter 6. Subsequently, after being evacuated by the evacuating pipe 9 inserted into the opening 4, the pipe 9 is removed, and the heat-sealing type 6 is approached, and the heater 10 is fused. ) Therefore, the inner bag 3', which was conventionally indispensable to prevent the powder 2 from scattering outside the bag 3 during vacuum suction, can be omitted, and the number of work steps can be significantly reduced. However, since the powder 2 taken out from the dryer can be directly filled into the bag 3, the time that the powder is in contact with the outside air is shortened, and moisture absorption of the powder can be prevented. time and improve work efficiency.

が得られるものである。As is clear from the above description, the present invention is designed to prevent the powder from scattering from the open end of a bag made of a metal-plastic laminate film, etc. when vacuuming is applied to a soft air-permeable plastic bag that is attached in advance near the open end of the bag. Since it is stopped by a filter made of foam, etc., it is possible to omit the inner bag, which was indispensable in the past, reducing the number of work steps1. Since it can be filled, the time that the powder is exposed to the outside air is shortened, and moisture absorption of the powder can be prevented.
This has the effect of shortening the evacuation time and improving workability.
