AbstractThe ink bag is structured as follows: To the respective long side portions (1a, 1b, 2a, 2b) of a rectangular-shaped, thermally fusible first film forming the surface portions (1, 2) of the ink bag, there are attached, by thermal fusion, the long side portions of a rectangular-shaped, thermally fusible second film forming the side surface portions (3, 4) of the ink bag and having lower rigidity than the first film to thereby form a cylindrical body. The one-side short side portions (1c, 2c) of the surface portions of the ink bag are attached together by thermal fusion to form a bag body. An ink supply hole forming member (5) is attached by thermal fusion to the other-side short side portions of the surface portions of the ink bag. In the four corners of the ink bag, there are formed band-shaped connecting portions (6 to 9) each starting from one of the two mutually adjoining sides of the ink bag and reaching the other of the two sides.Other References
