Abstract

A fluid container, such as, for example, an inkjet print head cartridge, architecture uses a relatively large filter that is located below a negative pressure material chamber and a free ink chamber in a side-by-side relationship. The negative pressure material volume relative to a free ink chamber value can me made to be approximately one to one. Both chambers overlie an ink manifold/delivery port and are separated from the delivery port by a filter. Flow impedance of the cartridge is reduced, as a result, in any orientation of the cartridge. The filter may be separated from, or in contact with a negative pressure material. A cartridge lid is provided with a negative pressure material chamber which is suspended into the cartridge. A negative pressure material having a fiber felt construction is provided.
