20090141101 | VALVE MECHANISMS AND INK CARTRIDGES - A valve mechanism includes a particular wall having a first opening formed therethrough, and a tube member including a particular surface which contacts the particular wall, and a central axis. The valve mechanism also includes a lid member configured to selectively cover and uncover the first opening, and a flexible inner wall positioned in an interior of the tube member. The flexible inner wall extends from the tube member to the lid member in a direction which intersects the central axis, and the flexible inner wall has a second opening formed therethrough. Moreover, a cross-sectional shape of the flexible inner wall in a particular plane is bent, and the central axis lies on the particular plane. | 2009-06-04 |
20090141102 | INK SUPPLY SYSTEMS - An ink supply system includes an ink cartridge and a cartridge mounting portion. The ink cartridge includes an ink chamber, and a tube having a first opening and a second opening formed therein. The first opening extends from a first end of the tube, and the second opening extends from a second end of the tube opposite the first end of the tube. The first opening is configured to be in fluid communication with the ink chamber via the first end of the tube, and the second opening is configured to be in fluid communication with an exterior of the tube via the second opening of the tube. The cartridge mounting portion includes a projection configured to be inserted into the second opening of the tube via the second end of the tube. A diameter of the second opening is less than an outer diameter of the projection. | 2009-06-04 |
20090141103 | INK CARTRIDGES AND METHODS OF MANUFACTURING SUCH INK CARTRIDGES - An ink cartridge includes a case, and the case includes an ink chamber configured to store ink therein, and a particular face facing an exterior of the case and having a first opening formed therethrough. The case also includes an engaging portion positioned at the particular face, and a particular wall extending from a particular portion of the particular face. The particular portion surrounds the first opening, and the particular wall has a tube shape. The particular wall includes an end defining a second opening opposite the first opening. The ink cartridge also includes an elastic member positioned at the end of the particular wall, and a cap. The cap includes an end wall having an third opening formed therethrough, a peripheral wall surrounding each of the elastic member and a portion of the particular wall, and an engaging member extending from the peripheral wall and engaging the engaging portion. | 2009-06-04 |
20090141104 | INK CARTRIDGES - An ink cartridge includes a case including an ink chamber configured to store ink therein, and a particular face facing an exterior of the case and having a first opening formed therethrough. The ink cartridge also includes an ink supply portion extending from a particular portion of the particular face in a particular direction, in which the particular portion surrounds the first opening, and the ink supply portion has a tube shape. The ink supply portion includes a particular chamber formed therein, an end wall having a second opening formed therethrough, and a peripheral wall extending from the end wall. The ink supply portion is configured to supply ink from the ink chamber to the exterior of the case via the particular chamber and the second opening. Moreover, the ink cartridge includes a plurality of protrusions. Each of the plurality of protrusions extend from the peripheral wall in a corresponding radial direction with respect to the peripheral wall, and extends in an axial direction of the peripheral wall. Each corresponding radial direction is perpendicular to the axial direction of the peripheral wall, and the axial direction of the peripheral wall is parallel to the particular direction. Moreover, each adjacent pair of the plurality of protrusions defines an ink holding space therebetween, and the ink holding space has a first end and a second opposite the first end, in which the first end is positioned closer to the end wall than the second end is positioned to the end wall, and the ink holding space is open at the first end. | 2009-06-04 |
