Ink tank for inkjet printer
The present invention relates to an ink tank for an ink jet printer. The invention further relates to a method of manufacturing the ink tank, as well as well as a method of refilling the ink tank. The ink tank includes an ink tank body and an ink tank lid bonded to the ink tank body at a bond joint. The ink tank lid comprises an opening that leads to a holding area that is adapted to contain a capillary media therein. The holding area comprises a wall that forms a boundary between the capillary media and an enclosure defined by the ink tank body and the ink tank lid. The opening is sized to permit an insertion and removal of the capillary media to and from the holding area when the ink tank lid is bonded to the ink tank body at the bond joint.
1. A method of manufacturing an ink tank comprising the steps of:
(a) attaching an ink tank lid to an ink tank body so as to form an enclosure therein, said ink tank body having a supply port;
(b) providing for an opening on said ink tank lid that leads to a holding area, wherein a wall that defines said holding area forms a boundary between said enclosure and said holding area;
(c) inserting a capillary media into said holding area through said opening; and
(d) filling said enclosure with ink through said supply port;
wherein at least said step (c) is performed with the ink tank lid attached to the ink tank body.
2. A method according to claim 1 , wherein after said enclosure is filled with ink, the method further comprises the steps of:
(e) closing said supply port; and
(f) providing a removable seal over said opening.
3. A method according to claim 1 , wherein said attaching step comprises forming a bond joint between said ink tank body and said ink tank lid through a vibration weld or a laser weld between the ink tank body and the ink tank lid.
4. A method of refilling an ink tank where ink in the ink tank has been previously consumed by a user, the ink tank having an ink tank lid that is bonded to an ink tank body, the method comprising the steps of:
(a) removing a protective cover from the ink tank lid, the ink tank lid comprising an opening which leads to a holding area, said holding area containing a capillary media therein;
(b) removing the capillary media from said holding area through said opening in said ink tank lid;
(c) inserting a new capillary media into said holding area through said opening; and
(d) refilling the ink tank with ink through a supply port on the ink tank body;
wherein at least steps (a) through (d) are performed with said ink tank lid being bonded to said ink tank body.
5. A method according to claim 4 , further comprising the steps of:
(e) closing the supply port; and
(f) applying a new protective cover over said ink tank lid;
wherein steps (e) to (f) are performed with said ink tank lid being bonded to said ink tank body.
6. A method according to claim 4 , wherein after said step (c) and before said step (d), the method further comprises:
(c1) flushing the ink tank body with a flushing liquid introduced into said ink tank body through at least one of the supply port or a vent to remove any remaining ink in the ink tank body, said step (c1) being performed with said ink tank lid being bonded to said ink tank body.
7. A method of refilling an ink tank where ink in the ink tank has been previously consumed by a user, the ink tank having an ink tank lid that is bonded to an ink tank body, the method comprising the steps of:
(a) removing a capillary media from a holding area defined by said ink tank lid through an opening in said ink tank lid;
(b) inserting a new capillary media into said holding area through said opening; and
(c) refilling the ink tank with ink through a supply port on the ink tank body;
wherein said steps (a) through (c) are performed with said ink tank lid being bonded to said ink tank body.
