  • Ink cartridge and air management system for an ink cartridge
    Patent number: 6966639
    Abstract: In one representative embodiment of the invention an ink cartridge includes a housing defining a first fluid reservoir, and an air management system having a fitment supported by the housing. The air management system also includes an expansible bladder which defines a second fluid reservoir and which is supported by the fitment within the first fluid reservoir. The expansible bladder is configured to expand to thereby increase the second fluid reservoir from a first volume to a second volume. The expansible bladder is fabricated from a material having a shape-memory to thereby bias the expansible bladder towards the first volume.
