真空断熱材パツクに関するものである。[Detailed Description of the Invention] The present invention relates to a vacuum heat insulating material pack that can be used as a heat insulating material for refrigerators and the like.

熱材パツクをシールした後、拡散し真空度を低く

ず品質上不安定さを残す問題があつた。 Conventionally, a problem in manufacturing vacuum insulation packs has been that as the thickness of the vacuum insulation pack increases, the vacuum degassing time increases exponentially, significantly reducing productivity. That is, usually 50μ
The following inorganic foamed powder was filled into an inner bag, a plastic-metal foil laminate film bag was inserted into the inner bag, and the bag was vacuum degassed to produce a vacuum insulation pack. However, since powders such as inorganic foam are extremely fine, the voids filled with each powder become discontinuous micropores, and as a result, attempts have been made to increase the thickness of the inner bag to make a thick vacuum insulation pack. As a result, the evacuation resistance at the center becomes very large, and even if the outer surface of the inner bag is vacuum-evacuated, reducing the degree of vacuum at the center is a very inefficient operation. Furthermore, after the moisture and air remaining in the center seal the vacuum insulation pack, it diffuses and lowers the degree of vacuum, resulting in deterioration of insulation properties, which causes instability in terms of not only work efficiency but also quality. It was hot.
本考案は上記点を考慮し、改良した真空断熱材
パツクを提供するものである。 The present invention takes the above points into consideration and provides an improved vacuum insulation pack.
以下、図面により本考案の一実施例を説明す
る。図において、１は真空断熱材パツクで、パー
ライト等の無機質発泡等の粉末２と、この粉末を
充填した中袋３と、プラスチツク−金属箔ラミネ
ート等のフイルム袋４を備えている。 An embodiment of the present invention will be described below with reference to the drawings. In the figure, reference numeral 1 denotes a vacuum insulation pack, which includes a powder 2 made of inorganic foam such as perlite, an inner bag 3 filled with this powder, and a film bag 4 made of plastic-metal foil laminate or the like.
前記フイルム袋４には少なくとも２個以上の中
袋３が入つており、その中袋３中には無機質粉末
２の必要量が分割されてそれぞれ充填されてい
る。なお、前記中袋３は通気性を有するポリエチ
レン繊維を含む不織紙等で形成され、無機質粉末
２を充填した後、開口面４′をそれぞれヒートシ
ールで封止している。 The film bag 4 contains at least two inner bags 3, each of which is filled with a required amount of inorganic powder 2. The inner bag 3 is made of nonwoven paper containing breathable polyethylene fibers, and after being filled with the inorganic powder 2, the opening surfaces 4' are sealed by heat sealing.
５は前記真空断熱材パツク１を収容する真空包
装機で、６は真空包装機５に取付られた開口面
４′をシールする自動ヒートシール機である。 5 is a vacuum packaging machine for accommodating the vacuum insulation material pack 1, and 6 is an automatic heat sealing machine for sealing the opening surface 4' attached to the vacuum packaging machine 5.
このように無機質発泡粉末２の全必要量を分割
して３つの中袋３に充填し、さらにこれらの中袋
３を１個のフイルム袋４に挿入し真空包装機７中
に入れて真空脱気するものである。したがつて、

である。さらに無機質発泡粉末２の中心部に残留
し、後で拡散し断熱性を劣化せしむる水分、空気

するのである。 In this way, the entire required amount of inorganic foamed powder 2 is divided and filled into three inner bags 3, and then these inner bags 3 are inserted into one film bag 4, placed in a vacuum packaging machine 7, and vacuum removed. It's something to be concerned about. Therefore,
Unlike the conventional method in which the required amount of inorganic foamed powder 2 is filled into one inner bag 3 and then inserted into a film bag 4 and vacuum degassed, the surface area of the inner bag 3 increases proportionally, and the center of the inorganic powder 2 is Since the distance to the inner bag 3 is shortened, the exhaust resistance is greatly reduced, and since the breathable inner bag 3 is used, the air can be exhausted through the inner bag 3, shortening the vacuum degassing time. This is possible. Furthermore, moisture and air that remain in the center of the inorganic foamed powder 2 and that would later diffuse and deteriorate the heat insulation properties can be sufficiently removed, contributing to quality stability.
本考案は、上述の如く、無機質粉末を、少なく

縮することができる。 As mentioned above, the present invention involves filling inorganic powder into at least two breathable inner bags, covering these inner bags with a film bag such as a plastic-metal foil laminate, and sealing the periphery. Unlike conventional methods in which the entire required amount of inorganic powder is filled into one inner bag and then covered with a film bag to reduce the pressure, the surface area of the inner bag increases proportionally, and Since the distance from the center of the inorganic powder to the inner bag is shortened, the exhaust resistance through the inner bag is greatly reduced, and the vacuum degassing time can be shortened.
さらに無機質粉末の中心部に残留し後で拡散し

きるのである。 Furthermore, moisture and air that remain in the center of the inorganic powder and later diffuse and deteriorate the heat insulation properties can be sufficiently removed, contributing to the stability of quality.
