Abstract
Multi-compartmentalized ink cartridges for ink jet printers and improved methods for making the ink cartridges. The multi-compartmentalized ink cartridge includes a molded, open-topped body having an interior cavity and a printhead surface area opposite the interior cavity. A divider wall is integrally molded with the molded body structure and disposed in the interior cavity to provide at least three segregated ink chambers. The divider wall includes a first wall section and a second wall section attached substantially perpendicular to the first wall section. At least first, second, third molded ink flow paths connect each of the at least three segregated ink chambers with the printhead surface area. The second and third ink flow paths are oriented relative to their corresponding ink chambers for molding with a mold insert tool so that the cartridge body does not require a separately attached member to close mold insert tool insertion areas in the body.
