本発明は、冷蔵庫等に使用する真空断熱材に関

する問題があつた。又、微粉末である前記粉末を
真空ポンプが吸引する危険性もあり、作業安定上
非常に大きな問題であつた。 Conventionally, vacuum insulation materials are produced by drying inorganic foamed powder such as crushed perlite to a moisture content of 1% or less, filling it into a film bag made of a laminate of metal and plastic, and then vacuum-evacuating the inside using a vacuum packaging machine. They used air and automatic heat sealing to create vacuum insulation materials. However, when a film bag is directly filled with inorganic foamed powder, the pulverized material adheres to the opening end of the film bag, and even if the opening end is heat-sealed, the seal may be incomplete and vacuum leaks may occur. Ta. Furthermore, there is a danger that the vacuum pump may suck in the powder, which is a fine powder, which is a very serious problem in terms of work stability.
本発明は上記点を考慮し、品質安定及び作業性

空包装機７の真空ポンプである。 An embodiment of the present invention will be described below with reference to the drawings. In the figure, 1 is a vacuum pack insulation material, and 2 is an inorganic foam powder such as perlite (hereinafter referred to as powder).
It is. Reference numeral 3 denotes a breathable inner bag such as a paper bag, which is filled with the powder 2 and whose opening end face 4 is adhered with tape, adhesive 5, etc. to prevent the powder 2 from leaking.
Incidentally, after filling the powder 2 to match the size and shape of the vacuum pack heat insulating material 1, the inner bag 3 is suitably pressed to form a shape, and then dried. 6 is an outer bag made of a film bag such as a laminate of metal and plastic, which is sealed on three sides in advance. Then, the inner bag 3 is inserted through the opening. 7 is a vacuum packaging machine, and 8 is a heat sealing machine installed in a vacuum chamber 9, which heat-seals the opening end face 10 of the film bag 6 by sandwiching it therebetween. 11 is a welding plate of the heat sealing machine 8, and 12 is a vacuum pump of the vacuum packaging machine 7.

空脱気する際、開口部端面１０から粉末２が飛散

完全に解決するのである。 In the above configuration, as shown in FIG. 2, first, the outer bag 3 filled with the powder 2, molded and dried is placed in the outer bag 6 sealed on three sides, and the outer bag 3 is fixed in the chamber 8 of the vacuum packaging machine 7. and the opening end surface 1 of the outer bag 6
0 is placed on the welding plate 11 of the heat sealing machine 8 and vacuum degassed. After the inside of the vacuum chamber 9 is degassed to 10 -2 torr., the heat sealing machine 8 is activated and the outer bag 6 is sealed.
The opening end face 10 of is heat sealed. As a result, as before, the powder 2 is directly filled into the outer bag 6,
The disadvantage that the powder 2 scatters and adheres to the opening end surface 10 when vacuum degassing is performed from the opening end surface 10 is completely eliminated because the inner bag 3 functions as a filter, and perfect sealing is possible even by heat sealing. As a result, the powder 2 adheres to the end face 10 of the opening, causing local unevenness, resulting in insufficient heat sealing and no risk of vacuum leakage. Furthermore, during vacuum degassing, the possibility that the powder 2 scatters from the opening end face 10 and contaminates the inside of the vacuum chamber 9, or that the vacuum pump 12 is sucked in and malfunctions, is completely resolved.

得られるのである。又、真空脱気時、無機質発泡
粉末体が飛散し、例えば真空チヤンバー内を汚し
たり、真空ポンプが吸引し動作不良になる可能性
についても解決するのである。 As described above, the present invention consists of a breathable inner bag filled with inorganic foamed powder and an exterior that houses this inner bag, reduces the pressure inside, and seals the end surface of the opening. As a result, the inorganic foam powder does not scatter during vacuum degassing, and there is no problem of adhesion to the open end surface of the outer bag and insufficient sealing during heat sealing.
Therefore, there is no risk of vacuum leakage, contributing to quality stability, and a heat insulating material with excellent heat insulation properties can be obtained over a long period of time. Furthermore, it also solves the possibility that the inorganic foam powder may be scattered during vacuum degassing, contaminating the inside of the vacuum chamber, or causing the vacuum pump to suck and malfunction.
さらに粉末を直接外袋に入れて型決めし真空包
装するのとは異なり、中袋に入れて型決めするた
め型決めの際のプレスによる微小なキズ付につい
ても配慮する必要はない。すなわち、フイルム袋
に入れて型決めするときのキズ付から真空リーク
する危険性がなくなるのである。 Furthermore, unlike the case where powder is placed directly into an outer bag, molded, and vacuum packaged, since the powder is placed into an inner bag and molded, there is no need to be concerned about minute scratches caused by pressing during molding. That is, there is no risk of vacuum leakage due to scratches when the film is placed in a film bag and molded.
さらに乾燥させる工程において中袋単体で乾燥
できるため表面積が十分とれ、均一な乾燥が可能
である利点を具備している。 Furthermore, in the drying process, since the inner bag can be dried alone, a sufficient surface area can be obtained, and it has the advantage that uniform drying is possible.
