  • Ink jet print head cartridge assembly
    Patent number: 4628334
    Abstract: The head comprises at least one nozzle (38) associated with two electrodes and carried by a holder (14) into which an ink cartridge (50) can be fitted. The cartridge is filled with ink and sealed after it has been filled. The cartridge terminates at one end with a cylindrical portion (60) which is closed by a diaphragm which can be ruptured upon insertion in the head. The diaphragm is ruptured by a tube (66) which projects within the holder and which communicates with the printing nozzles (38). The cylindrical portion (60) of the cartridge is offset with respect to the longitudinal axis of the cartridge to ensure correct insertion thereof. At the other end the cartridge is closed by a cover (87) having an aperture which is disposed above the free level (PL) of the ink and which is initially closed by a second diaphragm.
