Abstract
An inkjet cartridge is adapted to receive ink from an external ink supply reservoir. The inkjet cartridge includes an internal reservoir, printhead, housing, and fluid interface. The housing includes a first cylindrical port, a first connector and a second connector. The fluid interface provides fluid communication between the port and reservoir. An adapter secures a tube/needle valve from the supply reservoir to the port. The adapter includes a first member, a first protrusion and a second protrusion integrally formed as one structure. The first member defines an opening within which the needle valve is positioned. The first protrusion and second protrusion extend from the first member adjacent to the opening. The first protrusion engages the housing's first connector and the second protrusion engages the housing's second connector to attach the adapter to the housing. The valve mates to the port and a valve needle mates to the fluid interface.
