There is provided an ink cartridge device which permits a delivery port-sealing film thereof to be positively peeled off and prevents ink from scattering out of the device during an operation for peeling off the delivery port-sealing film. An ink cartridge has an ink delivery port for supplying ink to the printer therefrom, and a rim of the ink delivery port. A container box contains the ink cartridge and has a box body and a lid for closing the box body. The box body is formed with a slit. A delivery port-sealing film has a sealing portion removably welded to the rim of the ink delivery port, for sealing the ink delivery port, and an unsealing operation portion continuous with the sealing portion and extending in a direction of making a U-turn with respect to the sealing portion to extend out of the container box through the slit of the box body.
