Abstract
In one example, a fluid cartridge for an inkjet type liquid dispensing device includes a housing having a chamber therein for holding a liquid, a vent through which air may enter the chamber, and an outlet through which liquid may pass from the chamber out of the housing. A capillary material is disposed in the chamber between the vent and the outlet so that, when the capillary material is sufficiently depleted of liquid, the capillary material forms an airway from the vent to the outlet. The outlet configured to cause an abrupt break in a liquid connection in the outlet as air enters the outlet through the capillary material.
