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.
An ink-package assembly including an ink package fluid-tightly containing a mass of an ink, and a sealing wrapper fluid-tightly enclosing said ink package, wherein an interior space of said sealing wrapper is charged with an inert gas which has a lower degree of solubility in said ink, than the air,
An ink-package assembly including an ink package fluid-tightly containing a mass of an ink, and a sealing wrapper fluid-tightly enclosing said ink package, wherein an interior space of said sealing wrapper is charged with an inert gas which has a lower degree of solubility in said ink, than the air, and wherein said ink package includes a flexible ink bag having an opening at one end thereof, and is provided with a spout which is fixed to said opening, said spout having a passage for communication between an interior space and an exterior space of said ink bag, said flexible ink bag being further provided with a closure member press-fitted in said passage, and wherein said flexible ink bag containing the mass of the ink such that said passage is not filled with the ink, and is evacuated to a reduced pressure lower than the atmospheric pressure.
An ink-package assembly including an ink package fluid-tightly containing a mass of an ink, and a sealing wrapper fluid-tightly enclosing said ink package, wherein an interior space of said sealing wrapper is charged with an inert gas which has a lower degree of solubility in said ink, than the air, and wherein said interior space of said sealing wrapper is evacuated to a reduced pressure lower than the atmospheric pressure such that an inner surface of said sealing wrapper is just in contact with an outer surface of said ink package.
