Container superior in air-tightness and a method of keeping gas molecules or volatile components in the container

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.

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. 
     
     
         2 . A container superior in air-tightness as set forth in  claim 1  wherein the container is vacuum packaged with a film superior in gas-barrier properties, so that the surface of the container and the inner surface of the film high adhere to each other to unite the container and the film, thereby preventing the gas components from scattering and being lost from the inside of the container and improving the gas-barrier properties. 
     
     
         3 . A container superior in air-tightness as set forth in  claim 1  wherein when the container filled with hydrogen molecules, helium gas, smell component, or liquid, viscous fluid, or solid body each containing any of these gases is given a top or cap, and the whole of the container including the top or cap is then covered with a metal foil laminated film to be vacuum packaged, a pressure gauge of a vacuum packaging apparatus is −760 mmHg to −740 mmHg (gauge pressure notation/absolute vacuum is −760 mmHg). 
     
     
         4 . A container superior in air-tightness as set forth in  claim 1  wherein the liquid or viscous fluid containing hydrogen molecules is filled in the container up to its mouth without having any space (dead volume) at the upper part of the container. 
     
     
         5 . A container superior in air-tightness as set forth in  claim 1  wherein the container may employ a container made of resin provided by molding a material among resin such as polyethylene terephthalate (PET), polyamide (nylon), polyethylene (PE), polypropylene (PP) into a solid in shape of a bottle having thickness of 150 μm or more; a container in form of a bag made using a film less than 200 μm thick, such as a medical drip bag having a mouth for coinjection and a discharge port; a stand pouch type container (including gazette pouch) having a mouth cap (mouthpiece), or three-way-sealed packaging bag (including three-way-sealed packaging bag having back-bonding part), or four-way-sealed packaging bag, etc.; a metal can having a screw cap or a crown; a glass bottle, a ceramic bottle, or a container made of paper, wood, or bamboo.
