Abstract: A CONTAINER FOR CONTAINING LIQUID TO BE EJECTED.THE CONTAINER INCLUDES A NEGATIVE PRESSURE PRODUCING MEMBER ACCOMMODATING CHAMBER FOR ACCOMMODATING A NEGATIVE PRESSURE PRODUCING MEMBER. THE NEGATIVE PRESSURE PRODUCING MEMBER ACCOMMODATING CHAMBER IS PROVIDED WITH AN AIR VENT FOR FLUID COMMUNICATION WITH AMBIENCE AND A LIQUID SUPPLY PORTION FOR SUPPLYING THE LIQUID TO A LIQUID EJECTING HEAD HAVING EJECTION OUTLETS. THE CONTAINER ALSO INCLUDES A LIQUID CONTAINING CHAMBER WHICH IS SUBSTANTIALLY HERMETICALLY SEALED EXCEPT FOR A FLUID COMMUNICATION PATH THROUGH WHICH THE LIQUID CONTAINING CHAMBER IS IN FLUID COMMUNICATION WITH THE NEGATIVE PRESSURE PRODUCING MEMBER ACCOMMODATING CHAMBER. A PARTITION IS PROVIDED FOR SEPARATING THE NEGATIVE PRESSURE PRODUCING MEMBER ACCOMMODATING CHAMBER AND THE LIQUID CONTAINING CHAMBER. THE PARTITION IS PROVIDED WITH AN AMBIENCE INTRODUCTION PATH FOR INTRODUCING THE AMBIENCE INTO THE LIQUID CONTAINING CHAMBER FROM THE NEGATIVE PRESSURE PRODUCING MEMBER ACCOMMODATING CHAMBER. THE AMBIENCE INTRODUCTION PATH FORMS A CAPILLARY FORCE GENERATING PORTION. THE CAPILLARY FORCE WHICH IS PRODUCED BY THE CAPILLARY FORCE GENERATING PORTION SATISFIES A RELATIONSHIP BETWEEN THAT CAPILLARY FORCE AND POTENTIAL HEAD DIFFERENCES, HEAD LOSSES, AND OTHER CAPILLARY FORCES IN THE CONTAINER.(FIG 1)
