ABSTRACT:
An ink cartridge includes a bottom wall, a first surface having a first intersection with the bottom wall, a second surface having a second intersection with at least one of the bottom wall and the first surface, an ink chamber bounded, at least in part, by the bottom wall, the first surface and the second surface, and an ink supply opening for supplying ink in the ink chamber to a location outside of the ink chamber, the ink supply opening being provided in the bottom wall. The first intersection has a first curvature and the second intersection has a second curvature and the first curvature is greater than the second curvature, and at least a portion of the first intersection is closer to the ink supply opening than at least a portion of the second intersection.
