Abstract
An ink-package assembly including an ink package fluid-tightly containing a mass of an ink, and a sealing wrapper fluid-tightly enclosing the ink package, wherein an interior space of the sealing wrapper is charged with an inert gas such as a helium gas, which has a lower degree of solubility in the ink, than the air. The interior space of the sealing wrapper is evacuated to a reduced pressure of −20 kPa and −60 kPa with respect to the atmospheric pressure, as needed. The ink package includes an ink bag and is provided with a spout having a passage, and a cap for closing the passage. Where the sealing wrapper is evacuated, the ink package preferably further includes an ink-bag casing accommodating the ink bag, and a reinforcing structure interposed between the casing and the ink bag, to prevent deformation of the ink bag. Also disclosed is a method of producing the ink-package assembly.
