Abstract
An air-impermeable, nonporous seal member is disposed in the outlet passage of an ink cartridge. A housing in the cartridge has a chamber that stores ink therein and communicates with the outlet passage. The seal member is preferably formed of one of a rubber, polyvinyl chloride, thermoplastic rubber, or silicone rubber. The seal member frictionally engages an inner wall of the outlet passage and has a thin membrane that is selectively pierced by an associated needle of the printer.
