Abstract
An ink-cartridge package comprises a packaging bag. This packaging bag has a resin layer inside the bag, the resin layer being meltable and adherent to the ink cartridge. A portion of the packaging bag is stuck onto areas around the ink supply hole and the air hole on the ink cartridge surface by a heat sealing process in a peelable manner, whereby the ink supply hole and the air hole are sealed. The opening of the packaging bag is sealed, and a tear notch is formed in this heat-sealed edge at a position closer to the air hole than to the ink supply hole in order to allow the packaging bag to be opened from the air hole side. The packaging bag functions as both an enclosure of the ink cartridge and a sealing member for sealing the ink supply hole and the air hole of the ink cartridge, whereby the number of parts used in the package is reduced. In addition, this package can prevent the ink from scattering in an area surrounding the packaging bag when the ink cartridge is removed from the bag.
