  • Patent number: 5199470
    Abstract: A method and apparatus for refilling an ink cartridge include a device for clearing a hole in the cartridge to facilitate the dispensing of ink thereto. The device comprises a handle to which a bit is rigidly affixed so that torque applied to the handle is transmitted to the bit. The bit is arranged to extend along the handle's longitudinal axis. A kit for refilling an ink cartridge includes the aforementioned hole clearing device and a container containing a charge of ink and having a nozzle. The nozzle is formed so that it can pass through the hole cleared by the hole clearing device. In a preferred embodiment, the container is bellows shaped and compressible so that a user can compress the container and increase the rate at which the fresh ink charge is dispensed to the cartridge.
