摘要： PROBLEM TO BE SOLVED: To provide a liquid injection method of a liquid container in which a liquid can be injected without various functions of the liquid container being damaged, and to provide the liquid container.
SOLUTION: The liquid container of an atmosphere open type is equipped in a container body 10 with an ink containing part, an ink supply part, an ink guiding path which guides an ink I stored in the ink containing part to the ink supply part, and an atmosphere communicating path. A liquid residual quantity sensor which detects that a liquid residual quantity in the ink containing part becomes zero by detecting inflow of a gas into the ink guiding path is set halfway of the ink guiding path. At the same time, a bubble trapping passage 713 which captures bubbles mixed in the ink I is prepared in an upstream side ink end sensor connecting passage 400 between a detection position by the liquid residual quantity sensor and the ink containing part. The ink cartridge is constituted by forming an injection port to communicate with the liquid containing part in the atmosphere communicating path for the liquid container, injecting a predetermined quantity of the ink from the injection port, and sealing the injection port after the ink is injected.

摘要： PROBLEM TO BE SOLVED: To provide a manufacturing method for a liquid container in which a liquid can be simply and efficiently injected into a liquid containing chamber when the liquid container with the liquid held in the liquid containing chamber is manufactured, and which can contribute to effective utilization of resources by enabling reuse of a liquid container that has a liquid residual quantity reduced to a level of causing a liquid supply failure. SOLUTION: A differential pressure regulating valve 37 is set in an ink cartridge 11, which becomes a valve open state when the negative pressure at an ink supply port 24 side becomes constant or larger. The ink injected from the outside of a container body 12 is held in an ink containing chamber. The manufacturing method for the ink cartridge 11 includes a forcible valve opening process for forcibly turning the differential pressure regulating valve 37 in the valve open state against an exciting force which excites the differential pressure regulating valve 37 to a valve close state, and a liquid injection process for injecting the ink into the ink containing chamber via an ink passage from the ink supply port 24 while the forced valve open state of the differential pressure regulating valve 37 is maintained.
