    摘要： A print cartridge is described which has an ink recharge port and valve structure to enable the print cartridge reservoir to be recharged with ink. A slideable, generally cylindrical ink valve extends through the print cartridge body and into the ink bag. The valve has a male connector portion at its end external to the print cartridge body. The valve is open when pushed into the print cartridge body and closed when pulled away from the print cartridge body. An ink refill system containing a supply of ink has a slideable valve with a female connector portion which is engageable with the male connector portion of the print cartridge valve. To recharge the print cartridge ink reservoir, the end of the print cartridge valve is inserted into the end of the ink refill system valve to create both a mechanical coupling and a fluid tight coupling between the two valves. A further force pushing the print cartridge against the ink refill system causes both valves to be pushed inside their respective ink reservoirs. This further insertion causes both valves to become open, thus creating an airtight fluid path between the ink refill system reservoir and the depleted print cartridge reservoir. When the valves are mechanically decoupled, the valves are automatically closed.

    摘要： An ink refill system is described for engaging a print cartridge's refill valve and transferring ink to the ink reservoir. The ink refill system has a slideable valve with a female connector portion which is engageable with a male connector portion of a print cartridge valve. To recharge the print cartridge ink reservoir, the end of the print cartridge valve is inserted into the end of the ink refill system valve to create both a mechanical coupling and a fluid tight coupling between the two valves. A further force pushing the print cartridge against the ink refill system causes both valves to be pushed inside their respective ink reservoirs. This further insertion causes both valves to become open, thus creating an airtight fluid path between the ink refill system reservoir and the depleted print cartridge reservoir. The negative pressure within the print cartridge ink bag draws the ink from the ink refill system reservoir into the ink bag until the ink bag is substantially full. The print cartridge is then removed from the ink refill system, automatically closing both valves.

    摘要： An inkjet print cartridge is described which allows recharging of the ink supply in the print cartridge without removing the print cartridge from the printer. In a preferred embodiment, the ink reservoir in the print cartridge consists of a spring-loaded collapsible ink bag, where the spring urges the sides of the ink bag apart and thus maintains a negative pressure within the ink bag relative to ambient pressure. The ink bag is initially filled through a first fill port in the print cartridge. The first fill port is then sealed with a stopper. The print cartridge is installed in a slideable carriage in an inkjet printer. As the ink is depleted during use of the print cartridge, the ink bag progressively collapses and overcomes the spring force. A slideable, generally cylindrical ink valve extends through the print cartridge body and into the ink bag. The valve is open when pushed into the print cartridge body and closed when pulled away from the print cartridge body. An ink refill system containing a supply of ink is connected to the valve on the print cartridge by a flexible tube. The negative pressure within the print cartridge ink bag draws the ink from the ink refill system reservoir into the ink bag continuously or at intermittent times.
