ABSTRACT:
A bypass flowing passage communicating with the inside of a bag part not through a second valve mechanism is provided for an outlet part12, and ink can be filled from the outlet part into the bag part11despite the second valve mechanism V2. After an ink pack is housed in an inner case ink is filled into the ink pack. When a first seal film is welded to the inner case, the ends of the bag part are caught in a cartridge case because the bag part is not bulky. Therefore, the maximum amount of ink for the inner volume of the cartridge case can be filled. Further, since a bypass flowing passage is blocked after ink has filled the ink pack, contaminating of air bubbles into the bag part through the bypass flowing passage is prevented.
