Abstract
An ink tank includes a cap assembly attached to the ink tank by a preloaded hinge that defines a rotational axis of the cap assembly when the cap assembly is opened and closed. The preloaded hinge biases the cap assembly to an opened position when the cap assembly is unlatched. The cap assembly includes a cap housing, a bung retained within the cap housing, a spring disposed between the cap housing and the bung, a latch to hold the cap assembly in a closed position, where in the closed position the spring applies a force to provide a seal between the bung and the ink tank. The cap assembly also includes an effector that is operative when the cap assembly is unlatched, to sequence a closing of an internal valve of the ink tank and a breaking of the seal between the bung and the ink tank thereafter.
