ている。The gas seal 4 consists of a chamber 5 and a vacuum pump 6.
チャンバー５は、酸素を選択的に通す既知の半透膜７に
より、二つの空間８，９に分れている。The chamber 5 is divided into two spaces 8, 9 by a known semipermeable membrane 7 which selectively allows oxygen to pass through.
空間８は、夫々パイプ１０，１１を介して容器１と大気
に通じ、空間９は、パイプライン１２を介し真空ポンプ
６と接続している。The space 8 communicates with the container 1 and the atmosphere via pipes 10 and 11, respectively, and the space 9 is connected with the vacuum pump 6 via a pipeline 12.
本発明の装置は、以下のように作動する。The device of the invention operates as follows.
装置２において、例えば組成が窒素９５容量％、酸素５
容量％より成る窒素ガス雰囲気（即ち、酸素濃度の低い
保護性雰囲気）が作られ、パイプ３を介して容器１に供
給される。In the apparatus 2, for example, the composition is 95% by volume of nitrogen and 5% by volume of oxygen.
A nitrogen gas atmosphere consisting of % by volume (ie a protective atmosphere with a low oxygen concentration) is created and supplied to the container 1 via the pipe 3.
容器１では、この雰囲気中で物品が貯蔵される。In the container 1, articles are stored in this atmosphere.
貯蔵中は、容器１中の保護性窒素ガス雰囲気の組成を上
記割合に保つ必要がある。During storage, it is necessary to maintain the composition of the protective nitrogen gas atmosphere in the container 1 at the above ratio.
組成割合は、大部分ガスシール４の適切な作動に左右さ
れる。The composition ratio depends to a large extent on the proper operation of the gas seal 4.
作動モードには三形態がある。There are three modes of operation.
作動モード１
容器１中の圧力と気圧が同じ、あるいは容器１中の温度
が一定に保たれている場合は、パイプ１１を介し外の空
気がガスシール４の空間８に導入される。Operating mode 1 If the pressure and atmospheric pressure in the container 1 are the same or the temperature in the container 1 is kept constant, outside air is introduced into the space 8 of the gas seal 4 via the pipe 11.
真空ポンプにより空間９の中に作られる希薄化、ならび
に半透膜７ （例えばポリビニルトリメチルシラン膜）

では空気が窒素９５容量％迄濃縮される。dilution created in the space 9 by a vacuum pump, as well as a semipermeable membrane 7 (e.g. a polyvinyltrimethylsilane membrane)
Due to the difference in the diffusion rate of oxygen and nitrogen through the space 8, the air is concentrated to 95% by volume of nitrogen.
かくして、空間８中に窒素ガスのロックが生成し、容器
１は大気と隔離される。A lock of nitrogen gas is thus created in the space 8, and the container 1 is isolated from the atmosphere.
作動モード２
気圧が上昇あるいは容器１中の温度が降下する場合は、
外の空気がパイプ１１を介しゆっくりとチャンバー５の
空間８に入る。Operation mode 2 If the atmospheric pressure increases or the temperature in container 1 decreases,
Outside air slowly enters the space 8 of the chamber 5 via the pipe 11.
外空気は空間８中で、窒素分９５容量％に迄濃縮され、
パイプ１０を介し容器１に入る。Outside air is concentrated in space 8 to a nitrogen content of 95% by volume,
It enters the container 1 via the pipe 10.
作動モード３
気圧が降下あるいは容器１中の温度が上昇する場合は、
容器２中の窒素ガス雰囲気の一部が、パイプ１０、ガス
シール４のチャンバー５の空間８、ならびにパイプ１１
を介して、大気中に排出する。Operation mode 3 If the atmospheric pressure drops or the temperature in container 1 rises,
A part of the nitrogen gas atmosphere in the container 2 is transferred to the pipe 10, the space 8 of the chamber 5 of the gas seal 4, and the pipe 11.
into the atmosphere through.
かかる方法により、気圧や容器１中の温度が如何に変化
しても容器内と外気の圧力差が事実上存在しないので、
ガスシール４が、容器中の窒素ガス雰囲気の組成を一定
に保ってくれる。With this method, no matter how the atmospheric pressure or the temperature inside the container 1 changes, there is virtually no pressure difference between the inside of the container and the outside air.
The gas seal 4 keeps the composition of the nitrogen gas atmosphere in the container constant.
これにより、ガス交換はすべて、容器１の壁を介した漏
洩によらず、ガスシール４を介して行なわれる。Thereby, all gas exchange takes place via the gas seal 4, without leakage through the walls of the container 1.
