Abstract (en)
An ink cartridge includes a frame, and a film connected to the frame. The frame and the film define an ink chamber therein, and the ink chamber is configured to store ink therein. The ink cartridge also includes a movable member configured to selectively move within the ink chamber based on an amount of ink within the ink chamber, and a spring positioned within the ink chamber. The spring is configured to urge the film away from the movable member in a predetermined direction.
