Abstract: The present invention relates to a new structure of a fuel cartridge with light weight. The fuel cartridge of the present invention comprises a flexible container having an inner space to store liquid fuel, a connector connected to the flexible container and having an opening to discharge the liquid fuel; and a channel-forming structure or means provided in a inner space of the flexible container and connected to the connector, wherein the channel-forming structure or means is provided as a flow field interconnecting the inner space with an opening of the connector in order to discharge the liquid fuel when the channel-forming structure or means contacts with the flexible container near the connector. According to the present invention, coefficient of utilization of the fuel cartridge can be improved by preventing interference of a liquid fuel outflow due to close adhesion of the flexible container near the connector when the stored liquid fuel is discharged.
