Abstract

See full text

An ink refill cartridge is provided for refilling an ink ejection printhead cartridge. The refill cartridge includes a receptacle configured to receive a collapsible ink container storing ink. The receptacle is further configured to engage with an ink refill port of the printhead cartridge. A handle assembly can be slidably mounted relative to the receptacle so that, when the handle assembly and receptacle are compressed between the printhead cartridge and a hand, the handle assembly can slide along the receptacle and collapse the ink container to cause the stored ink to be supplied through the ink refill port. In one embodiment, the receptacle defines one or more protrusions configured to engage with complementary recesses of the handle assembly so that the handle assembly will not slide along the receptacle until a threshold compression force has been applied by the hand.
