초록 ▼

An ink cartridge supplies an inkjet printhead by forming a sealed engagement with an inlet on the printhead. The ink cartridge has an ink storage volume, an outlet opening in fluid communication with the ink storage volume, an outlet valve for connection to an inlet on the inkjet printhead, the outlet valve having a radially extending flange portion fixed within the outlet opening and, an annular skirt of resilient material extending from the outlet opening to the flange portion. The resilient material elastically biases part of the annular skirt into sealing engagement with the flange portion to close the outlet valve. Engagement with the inlet on the printhead during installation of the ink cartridge, compresses the annular skirt to open the outlet valve such that ink flows from the ink storage volume around the radially extending flange portion to the printhead.

1. An ink cartridge for an inkjet printhead, the ink cartridge comprising: an ink storage volume;an outlet opening in fluid communication with the ink storage volume;an outlet valve for connection to an inlet on the inkjet printhead, the outlet valve having a radially extending flange portion fixed within the outlet opening; and,an annular skirt of resilient material extending from a side of the outlet opening to the flange portion, the annular skirt being configured such that the resilient material elastically biases part of the annular skirt into sealing engagement with the flange portion to close the outlet valve; wherein,the annular skirt is configured such that engagement with the inlet on the printhead during installation of the ink cartridge, compresses the annular skirt to open the outlet valve such that ink flows from the ink storage volume between the annular skirt and central stem to flow around the radially extending flange portion to the printhead. 2. The ink cartridge according to claim 1 further comprising the ink storage volume and an air inlet in fluid communication with a variable volume structure within the ink storage volume. 3. The ink cartridge according to claim 2 wherein the variable volume structure is an air bag such that upon installation in the printer, the air inlet vents the air bag to atmosphere. 4. The ink cartridge according to claim 3 wherein the air inlet has a frangible seal that is ruptured upon installation in the printer. 5. The ink cartridge according to claim 4 wherein during use the variable volume structure in the ink storage volume expands to keep a constant head of ink above the outlet valve. 6. The ink cartridge according to claim 5 further comprising a rigid housing, the housing having a docking face for abutting a complementary face on the printer, wherein the outlet valve and the air inlet are both in the docking face. 7. The ink cartridge according to claim 6 wherein the outlet valve and the air inlet are recessed into the docking face. 8. The ink cartridge according to claim 7 wherein the outlet valve and the air inlet are configured to be opened simultaneously as the cartridge is installed. 9. The ink cartridge according to claim 8 wherein the docking face is substantially flat. 10. The ink cartridge according to claim 7 wherein the outlet valve and the air inlet are at spaced locations on the docking face. 11. The ink cartridge according to claim 5 wherein the cartridge further comprises a conduit in the ink storage volume, one end of the conduit being connected to the outlet valve and other end being open to ink within the ink storage volume and positioned such that it does not get obstructed by the air bag as it inflates. 12. The ink cartridge according to claim 11 wherein the ink storage volume is partially defined by a roof wall, the roof wall being substantially flat, parallel to, and directly opposite the docking wall such that the cartridges are vertically stackable on each other. 13. The ink cartridge according to claim 8 wherein the docking face defines part of the ink storage volume and the air bag is adjacent the docking face such that in use, the air bag expands upwardly in the storage volume. 14. The ink cartridge according to claim 13 wherein the air bag has flat top and bottom sheets separated by side walls folded in a concertina fashion when the air bag is deflated.
