Claims
- 1. A method for packing an ink tank cartridge for storage having an ink absorbing member impregnated with ink at a pressure below atmospheric pressure, comprising the steps of:
- wrapping the ink tank cartridge with a fuse bondable film essentially impermeable to air;
- fuse bonding the free ends of the film to form an air sealable container having a space therein; and
- at least partially decompressing the container as it its fuse bonded so that the pressure in said space is lower than the atmospheric pressure and higher than the pressure at which the ink absorbing member was impregnated with ink.
- 2. The method of claim 1, wherein said space is at least 15% of the total inside volume of said container.
- 3. The method of claim 1, further including the step of inserting absorbing members in the space of the container for maintaining the low pressure within the container.
- 4. The method of claim 3, wherein the absorbing members include sponge grains.
- 5. The method of claim 1, wherein the film is a laminate film including at least a layer of aluminum.
- 6. The method of claim 1, further including the step of maintaining the pressure in the container as a negative pressure slightly higher than the pressure used when storing ink in the ink tank cartridge.
- 7. A method for packing an ink tank cartridge for storage having an absorbing member impregnated with ink to form an air sealable container, comprising the steps of:
- wrapping the ink tank cartridge with a fuse bondable film essentially impermeable to air;
- fuse bonding the free ends of the film to form an air sealable container having a space therein; and
- at least partially decompressing the container as it is fused bonded so that the pressure in said space is lower than the atmospheric pressure and higher than the pressure at which the ink absorbing member was impregnated with ink and said space represents at least 15% of the total inside volume of the container.
- 8. The method of claim 7, further including the step of inserting absorbing members in the space of the container.
- 9. The method of claim 7, wherein the film is a laminate film including at least a layer of aluminum.
- 10. The method of claim 8, wherein the absorbing members include sponge grains.
- 11. The method of claim 1, further including the step of maintaining the pressure in the container in the range of -600 to -650 mmHG and the pressure of the ink as -700 mmHG.
- 12. The method of claim 7, further including the step of maintaining the pressure in the container in the range of -600 to -650 mmHG and the pressure of the ink as -700 mmHG.
