ABSTRACT:
An ink cartridge for a thermal ink jet printer containing a separate collapsible ink reservoir which is kept under negative pressure by a pressure regulator to prevent ink leakage. The collapsible reservoir has one or more flexible sidewalls connected at their periphery to form an ink reservoir, wherein said sidewalls include a plurality of layers. The pressure regulator comprises a pair of spaced parallel side plates urged apart by a spring toward the adjacent reservoir sidewalls whereby the reservoir is collapsible against the spring pressure to an essentially flat shape to permit substantially complete dispensation of ink from the reservoir.
