PROBLEM TO BE SOLVED: To obtain an ink preserving container provided with vibration resistance while ensuring gas barrier properties and an ink take-out port structure for enhancing the use efficiency of ink in which defective ink supply due to pasting of a film to the take-out port is prevented while having a hermetic structure. SOLUTION: Mechanical strength and vibration resistance against vibration of an aluminum foil are ensured by setting the thickness of a resin film wrapping the aluminum foil appropriately while ensuring the gas barrier properties by means of the aluminum foil. When a take-out port 3 is provided on the upper surfaces of ink preserving containers 1, 2, the film is prevented from pasting the end face at the take-out port by means of a rib while ensuring airtightness of the housing thereof easily and thereby defective ink supply is prevented. |
