Without any sealing operation in the present invention relates vacuum chamber, can be accommodated in the packaging material solids easily, yet the gap between the packaging material and the solid is eliminated if it is sealing the packaging material, solid I will provide a method of packaging. Then SOLUTION, when accommodated in a packaging material solids, and sealing, is introduced into the packaging material in intentionally, the replacement gas having a property of being absorbed by the solids. Thus, the replacement gas is absorbed into a solid after sealing, the gap between the packaging material and the solids is reduced, and the packaging material and solids come into close contact. The absorption of the replacement gas is an equilibrium state, the volume of the package will remain constant. On the other hand, when it is open the package, a gap occurs between the packaging material and solids. [Selection] Figure Figure 1【課題】 真空装置内で密封作業を行わなくても,容易に固形物を包材に収容させることができ,しかも包材を密封した場合に固形物と包材との隙間がなくなる,固形物の包装方法を提供する。【解決手段】 そして,固形物を包材に収容し,密封する際,固形物に吸収される性質を有する置換ガスを,あえて包材内に導入する。これにより,密封後に置換ガスが固形物に吸収されるので,固形物と包材との隙間が小さくなり,固形物と包材とが密着する。そして,置換ガスの吸収が平衡状態となると,包装体の体積が一定の状態を維持する。一方,包装体を開放した際には,固形物と包材との間に隙間が生ずる。【選択図】図1
