ABSTRACT:
A fine pressure fluctuation at short time intervals occurring when a portable type hermetically sealed container is purged is reduced to thereby prevent the deterioration or the like of a seal member due to the pressure fluctuation. In order to achieve this object, a gas flow rate regulating apparatus is disposed in a gas supplying system in a purging system, and pressure in the portable type hermetically sealed container during purge is measured and the result thereof is fed back to thereby control the flow rate of a supplied gas.
