PURPOSE:To prevent dissolving of air into ink during storage and to enable storage for a long period within a package container by using a package container which contains ink cartridges and by filling the container with a gas which has solubility into ink less than the air. CONSTITUTION:The head body and ink bags are built-in within a head cartridge 10. The cartridge package container 11 is filled with a gas which has less solubility into ink, for instance, helium gas, etc., when the head cartridge 10 is packed. By constituting a hermetically sealed package 12 as stated above, dissolving of gas into ink is suppressed. |
