Abstract:
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.
