Ink cartridge and printer

摘要

An ink cartridge (4) includes a bag (42) filled with ink and sealed. The bag is housed in a cartridge case (41). The bag is formed out of a laminate (30) including a ductile film (20) and a rigid film (22) which are laminated together. The case has a hole, through which a hollow needle (7a) 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. <IMAGE>
