LIQUID SUPPLY METHOD, LIQUID SUPPLY CONTAINER, NEGATIVE PRESSURE GENERATING MEMBER CONTAINER, AND LIQUID CONTAINER.

摘要

There is disclosed a liquid supply method in which a bubble is prevented from being retained or accumulated in a communication part. An upper wall surface (122) of a joint pipe (180) for connecting a negative pressure control chamber container (110) to an ink container (201) is inclined upward to the ink container (201) from the negative pressure control chamber container (110). Since the upper wall surface (122) of the joint pipe (180) is inclined, the bubble flows into the ink container (201) without being retained or accumulated on the upper wall surface (122) of the joint pipe (180) during gas-liquid exchange. The flow resistance of the joint pipe is thus reduced toward the ink container. Also other means for reducing the flow resistance are disclosed.
