ABSTRACT:
A fluid ejection container system provides a first container that contains the fluid, the first container being evacuated to negative gauge pressure when being filled with the fluid, a second container having a capillary medium that contains the fluid, a passage between the first and second containers communicating the fluid at a level wherein the passage is wetted with the fluid, a ventilation port to communicate air between an interior region in the fluid ejection system and ambient, at least one spill over region to communicate the fluid with the second container, and a plurality of channels to communicate at least the air between the interior region and the second container; wherein the at least one spill over region has sufficient volume to contain a quantity of the fluid that migrates out of the second container. The fluid ejection container system also provides a lid for sealing the first and second containers from the ambient, wherein the channels are disposed on the lid.
