Abstract
An ink cartridge includes a bag filled with ink and sealed. The bag is housed in a cartridge case. The bag is formed out of a laminate including a ductile film and a rigid film which are laminated together. The case has a hole, through which a hollow needle can protrude from the outside into the case and pierce the bag to take out ink from the bag. The laminate has such a sealing effect that, when it is pierced by the needle, the pierced hole is blocked. The cartridge is suitable for an ink jet printer.
