Device for ink refill of a reservoir in a print cartridge. |
摘要 |
<p>An ink refill device includes a body (18) having a chamber (19) with ink (20) therein. The chamber has one wall (22) formed of a frangible material. The body has a needle (27) for communicating the chamber with a reservoir (11), which has a foam (12) of a controlled porosity therein, in a print cartridge (14) when the needle is inserted in a vent (15') of the reservoir to fill the same. Breaking of the frangible wall of the chamber with the needle extending downwardly enables ink to flow from the chamber at a controlled flow rate to the reservoir in the cartridge. In a preferred embodiment the needle has one or more notched openings (29) adjacent its distal end to increase its surface area through which ink flows, to increase flow of ink to the reservoir. <IMAGE></p> |
