Title: Ink container with secondary containment for ink supply

Abstract: An ink container for a supply of liquid ink includes a pressure vessel defining an interior chamber and a collapsible ink reservoir disposed within the interior chamber. The collapsible ink reservoir is adapted to hold the supply of liquid ink therein such that an ink passage communicates with the collapsible ink reservoir and externally of the pressure vessel, and an air passage communicates with the interior chamber of the pressure vessel and externally of the pressure vessel. A flow restrictor communicates with the air passage and, therefore, the interior chamber to restrict flow through the air passage from the interior chamber and permit flow through the air passage into the interior chamber.
