<p><P>PROBLEM TO BE SOLVED: To provide a manufacturing method for an ink container which can improve the use efficiency of ink. <P>SOLUTION: An opening is formed at a right side face 46 of a frame 50. An ink chamber 100 is formed when the opening is shut by a film 65 in the first process. A first cover is arranged outside the film 65 in the second process, whereby the film 65 and an inner wall face of the first cover are opposed to each other. The film 65 adheres to the inner wall face when an atmospheric pressure outside the ink chamber 100 is lowered relatively to an atmospheric pressure inside the ink chamber 100 in the third process. A protrusion extended in the horizontal direction is thus formed to the film 65 while an ink cartridge is attached to an image recorder. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
