Abstract: A fluid cartridges, such as a cartridge for storing ink for use in an ink jet printer. The cartridge includes a fluid chamber for storing fluid, a fluid outlet and a vent opening. A capillary member having an internal capillary chamber is attached to the fluid outlet port. A plurality of ribs in the capillary chamber terminate a short distance from the inner surface of the capillary chamber, and thereby define a plurality of capillary gaps or openings. An ink outlet opening is formed in an end of the capillary member remote from the in outlet port in the cartridge, whereby the fluid chamber is in fluid communication with the external environment via the vent opening, the capillary chamber, and the ink outlet port.
