PROBLEM TO BE SOLVED: To provide a liquid container which suppresses variations in a pressure occurring on an inflow of air bubbles to a liquid storage chamber, in the liquid container using a principle of Mariotte's bottle.SOLUTION: When liquid in the liquid storage chamber flows out of an outflow port to reduce a pressure in the liquid storage chamber, air supplied through an air passage which is communicated with the air is caused to flow into the liquid in the liquid storage chamber as air bubbles from an air introduction part to raise the pressure in the liquid storage chamber. Further, a plurality of air introduction holes are disposed on the air introduction part, wherein each air introduction hole is set to be smaller than a cross-section of a part where the air introduction part in the air passage is disposed. In such a manner, the air bubbles flowing into the liquid storage chamber are minimized and the variations in the pressure in the liquid storage chamber can be suppressed. Further, the air bubbles are caused to flow in through the plurality of air introduction holes and, thereby, an flowing amount of air into the liquid storage chamber can be secured. |
