ABSTRACT:
The present invention is directed toward an ink cartridge refilling structure having a housing structure with a base structure and a housing lid structure. The housing lid structure has first and second outwardly opening chambers formed therein with a spring biased ink injection device received in the first chamber and an air plunger member with an associated air bellow member received in the second chamber. The base structure has positioned within its interior a moveable carrier member that is secured to a lever that extends outwardly through a slot extending horizontally and longitudinally along the side wall of the base structure. An empty ink cartridge is placed in the carrier member within interior of the base structure and refilled with ink. The carrier member and ink cartridge are then shifted over to the air injection position where air is injected into the air bags of the ink cartridge.
