（産業上の利用分野）
本発明は、ガス充填包装体、特に、被包装物の内部の減
圧状態を長期間確実に維持しうる可撓性に冨むガスバリ
ヤ−性包装体に関する。Detailed Description of the Invention (Industrial Application Field) The present invention relates to a gas-filled package, particularly a gas-filled package having gas barrier properties that are highly flexible and capable of reliably maintaining a reduced pressure state inside the packaged object for a long period of time. Regarding packaging.
（従来の技術）
例えば、血液検査用容器として用いられる真空採血管な
どの容器は、減圧状態が長期間にわたり維持される内部

、減圧状態が速やかに失われる。(Prior Art) For example, a container such as a vacuum blood collection tube used as a blood test container must have an internal structure that maintains a reduced pressure state for a long period of time. For example, vacuum blood collection tubes are made of plastic material, but since plastic material has a certain degree of gas permeability to oxygen, carbon dioxide, and water vapor in the atmosphere, if it is left as it is, it will quickly lose its pressure. Lost.
このような問題を解決するために３通常、この容器を別
の包材で真空包装することが行われている。真空包装に
用いられる包材としては１例えば。In order to solve these problems, 3 the container is usually vacuum packaged using another packaging material. Examples of packaging materials used for vacuum packaging include:
金属缶やアルミ箔ラミネートフィルムなどがある。There are metal cans and aluminum foil laminated films.
前者の金属缶は、剛体であるため、被包装物を保護する

生じ易い。一度包村内へ酸素などのガスの浸入を許すと
、被包装物はその減圧状態を維持しえなくなる。それゆ
え、アルミ箔のガスバリヤ−性は完全ではない。Since the former metal can is a rigid body, it is excellent in protecting the packaged item. Furthermore, it also has excellent gas barrier properties. However, it has the disadvantage of being heavy and bulky. It is also expensive. The latter aluminum foil laminate film has advantages such as being flexible, lightweight, and not bulky. However, since it comes into close contact with the packaged item, it may crush and damage the packaged item. Moreover, since aluminum foil has poor bending strength and tear strength, for example, pinholes are likely to occur at wrinkled portions. Once gases such as oxygen are allowed to enter the package, the packaged item will no longer be able to maintain its reduced pressure state. Therefore, the gas barrier properties of aluminum foil are not perfect.

（問題点を解決するための手段）

らの衝撃により損傷することもない。The present invention is characterized in that, in the gas-filled packaging described above, the gas filled in the space between the object to be packaged and the plastic packaging material is a gas that is difficult to pass through both, and the pressure thereof is set to be equal to or higher than atmospheric pressure. This eliminates the poor gas barrier properties of plastic packaging materials. This is an application of the principle of reverse osmosis in which the movement of chemical species through a semipermeable membrane can be controlled by applying a pressure greater than the osmotic pressure generated through the membrane. Therefore, the gas that fills the inside of the plastic packaging material prevents atmospheric oxygen, carbon dioxide, water vapor, and the like from entering the inside of the packaging material. Thereby, the packaged object made of plastic does not come into contact with these gases, and the internal reduced pressure state can be reliably maintained for a long period of time. Since the filled gas also has the function of protecting the packaged items, the packaged items will not be damaged by impacts from outside the packaging material.
