PROBLEM TO BE SOLVED: To simplify the design of an ink cartridge. SOLUTION: In a structure for assembling an atmosphere open valve 601 in an atmosphere open chamber 501 comprising a container body 2 having a through hole 60 communicating between an ink containing chamber and the atmosphere open chamber 501, and the atmosphere open valve 601 having a valve element 65 capable of opening/closing the through hole 60 of the container body 2 and a resilient member 62 capable of pressing the valve element 65 in the closing direction, the valve element 65 is located at a position for closing the opening of the through hole 60, the resilient member 62 is positioned in the atmosphere open chamber 501 by developing a bend piece wherein the resilient member 62 is arranged such that one end part thereof presses the valve element 65 in the closing direction under positioned state and the other end part is secured into the atmosphere open chamber 501. |
