Abstract
An ink container shell for an ink jet cartridge has spaced apart side walls, a front wall, a rear wall, and a bottom wall, and is provided with a partition structure which divides the interior thereof into three ink chambers, at least one of which has a non-rectangular profile in cross-section transverse to said side, front and rear walls. The partition structures enable varying the volumes of the ink chambers with respect to a given shell exterior profile and enable isolating two the chambers from one another by interposing the third chamber therebetween.
