Patent abstract
An ink cartridge for an ink-jet recording device that includes first and second ink bags adapted to hold ink therein, and an ink channel formed between the first and second ink bags for supplying the first ink bag with the ink from the second ink bag. The ink channel is capable of being opened and closed by a closing mechanism provided to the ink-jet recording device. For example, the ink channel is made of flexible material so that the closing mechanism can close the ink channel by pressing it with a pressing member provided to the closing mechanism. The ink cartridge further includes an ink flow enhancing mechanism that allows the ink to flow smoothly through the ink channel when the ink channel is not closed by the closing mechanism.
