Abstract
A fluid cartridge for dispensing fluid, such as liquid ink for a drop on demand ink jet printer, includes a housing that encloses a capillary chamber, and has an outlet port through the one wall of the housing into the capillary chamber. Capillary material in the capillary chamber is arranged so that it has a higher density adjacent the outlet port than away from the outlet port, to enhance the flow of the fluid toward the outlet port. The interior of the capillary chamber is structured to provide greater compression to the capillary material around the outlet port, and provide stability to retain the variable compression of the capillary material.
