Abstract
An ink bottle is mounted in a DOD printer with the ink bottle acting as an ink supply reservoir that supplies ink to a DOD print head. A unique cap is provided that is configured to be affixed to an end of the ink bottle via threads or the like. The cap can be provided with one or more mechanical keying features used to limit mounting of the cap and the bottle assembly to a correct receiver in the DOD printer. The cap can also be provided with a valve controlled ink passage that allows ink to flow out of the bottle through the cap and a valve controlled vent passage that allows air to enter the bottle through the cap.
