PURPOSE:To facilitate the visual determination of the quantity of remaining ink, by providing a member having a specified shape in an ink container. CONSTITUTION:Before an ink container 1 is formed in the shape of a bag, a member 9 shaped in a character or a mark for facilitating the supply of ink is provided inside the ink container 1 by thermal welding. Owing to the above- described construction, the shape of the memer 9 appears clearly as rise and fall in the surface of the ink container due to the flexibility of the container with the consumption of the ink inside the container. Consequently, the quantity of the remaining ink can be determined visually with ease. |
