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 floor having a vent and an ink outlet. The ink flow path from the housing outlet to the printhead inlet is produced by an elongated recess in the outer surface of the housing floor and a film member bonded thereover by an adhesive not attacked or eroded by the ink. The film member has a slot therethrough to provide communication with the inlet of the printhead. The surface of the film member opposite the surface bonded to the housing floor is coated with a 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. The adhesive bonding the film member to the housing floor is either a pressure sensitive adhesive or the same thermosetting as is sued on the other side of the film member.
