摘要： A fluid cartridge, such as a cartridge for filling with ink for use in ink jet printhead includes a wick chamber that has outer walls, including a top wall, and an ink chamber formed of a plurality of outer walls. A fluid conduit connects the ink chamber and the wick chamber. The outer walls of the ink chamber are formed to provide no fluid communication between the ink chamber and the ambient environment, except through the fluid conduit and the wick chamber. A vent opening through the top wall of the wick chamber provides communication between the wick chamber and the ambient environment, and an outlet opening through an outer wall other than the top wall of the wick chamber provides fluid communication for the ink to flow from the wick chamber. A vent tube extends from the vent opening into the interior of the wick chamber, and projections extend from the top wall of the wick chamber into the interior of the wick chamber, farther than does the vent tube.

摘要： A fluid cartridge, such as a cartridge for filling with ink for use in ink jet printhead includes a housing enclosing a wick chamber, the housing including a top wall. The housing also includes an ink chamber. A fluid conduit connects the ink chamber and the wick chamber. The outer surface of the top wall of the housing is formed with a recess. A vent opening through the top wall of the wick chamber, at the recess, provides communication between the wick chamber and the recess. A covering over the top surface of the housing encloses the recess. An outlet opening through an outer wall other than the top wall of the wick chamber provides fluid communication for the ink to flow from the wick chamber. One end of an overflow tube is in fluid communication with the recess in the top wall of the housing. The other end of the overflow tube opens to the ambient environment at another point on the exterior of the housing near the outlet opening so that the potential “wet” spots on the exterior of the cartridge are in the same area.

摘要： 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.

摘要： A fluid cartridge, such as a cartridge for filling with ink for use in ink jet printhead includes a wick chamber that has outer walls, and forms a wick chamber and a fluid chamber. The outer walls of the fluid chamber are formed to provide no fluid communication with the fluid chamber except through the wick chamber. The ink fluid cartridge is filled by evacuating gas from the ink chamber and from the wick chamber, and then supplying ink into the wick chamber until the ink substantially saturates the wick material, and flows into the ink chamber.

An outlet opening through an outer wall other than the top wall of the wick chamber provides fluid communication for the ink to flow from the wick chamber. One end of an overflow tube is in fluid communication with the recess in the top wall of the housing. The other end of the overflow tube opens to the ambient environment at another point on the exterior of the housing, such as near the outlet opening. A dam in the recess, between the vent opening and the one end of the overflow tube impedes, but does not completely obstruct the flow of spillover ink from the vent opening into the overflow tube.
