Abstract: An example ink tank includes an ink tank and a cap assembly attached to the ink tank with a preloaded hinge. The hinge rotates the cap assembly from a closed position to an open position when the cap assembly is unlatched. The cap assembly includes a bung to seal the ink tank during a partial rotation of the cap assembly when the cap assembly is unlatched. The ink tank also includes spring-loaded linkage connected to a valve in the ink tank. An effector extending from the cap assembly engages the spring-loaded linkage when the cap assembly is latched and disengages from the spring-loaded linkage after the cap assembly is unlatched. The spring-loaded linkage opens the valve when engaged with the effector, and closes the valve when disengaged from the effector, while the bung maintains a tank seal until the internal valve is closed.
