ABSTRACT:
An ink cartridge for an ink jet printer has an ink supply in a housing and a printhead assembly fixedly attached thereto. The ink is contained in an absorbent material in the housing which is partitioned from the printhead assembly by a housing wall having a vent and an ink outlet. The ink flow path from the housing outlet to the printhead inlet is produced by a recess in the outer surface of the housing wall and a film member bonded thereover by a thermosetting adhesive. The film member has a slot therethrough, and the adhesive is the type not attacked by the ink. The surface of the film member opposite the surface bonded to the housing wall is coated with the same thermosetting adhesive which bonds to the printhead assembly surface containing the ink inlet. The printhead assembly ink inlet is of similar size and aligned with the film member slot, so that the thermosetting adhesive assists in the attachment of the printhead assembly to the housing and concurrently provides the fluid seal between the housing and the printhead assembly.
