CONTAINER SUPERIOR IN AIR-TIGHTNESS AND A METHOD OF KEEPING GAS MOLECULES OR VOLATILE COMPONENTS IN THE CONTAINER
First Claim
1. A container superior in air-tightness characterized in that the container is filled with hydrogen molecules, helium gas, smell component, or liquid, viscous fluid, or solid body each containing any of these gases and is given a cap or sealed, and the whole of the container including the cap or seal is then packed with a metal foil laminated film superior in resistance against gas permeability (gas-barrier properties) to be vacuum packaged.

Abstract
A bottle made of polyethylene terephthalate does likely undergo that a gas having a small molecular weight or volatile component escapes from the bottle in a short time in comparison with a glass bottle, steel can, and aluminum can. For a countermeasure, a simple operation prevents hydrogen molecules, helium gas, and volatile component from scattering and being lost. A container filled with gas, or liquid or viscous fluid in which gas is dissolved, or metal granules adsorbing gas is given a cap, and then, the whole of the container including the cap is packed with a metal foil laminated film superior in gas-barrier properties to be vacuum packaged.
