Abstract
An ink supply comprises an ink container having an opening for releasing ink and a valve member and a mechanism for biasing the valve member so as to prevent the flow of ink from the container when the ink supply is not mounted on a supply base. The ink jet system includes an ink reservoir, a cover enclosing the reservoir, and a neck having a threaded inner surface engaging the ink supply when the ink supply is inserted within a first opening within the neck The cover has a second opening that is concentric with and below the neck and the first opening to permit ink to flow from the ink supply, through the second opening and into the reservoir. A flat shoulder of the cover surrounds the second opening and controls the ink supply by stopping further insertion once the ink supply is fully mounted,
