Abstract:
1. A liquid filling method of filling a liquid into a liquid container designed to be attachable to and detachable from a liquid consuming device and to store a liquid, which is to be supplied to the liquid consuming device, the liquid container being structured to include: a first chamber arranged to store the liquid therein; a second chamber located in the downstream of the first chamber or at a closer side to the liquid consuming device in a pathway of the liquid and arranged to communicate with the first chamber and store the liquid therein; a sensor unit located in the downstream of the second chamber and arranged to receive therein a sensor used for detecting a consumption level or a remaining level of the liquid; a liquid feeder located in the downstream of the sensor unit and arranged to supply the liquid stored in the first chamber and in the second chamber to the liquid consuming device; an air open structure arranged to connect the first chamber with the outside air via an air communication path; a bubble trap flow path located in the upstream of the sensor unit and in the downstream of the second chamber, formed to have cylindrical flow paths turned down upward in a certain attitude of the liquid container attached to the liquid consuming device, and designed to trap bubbles; and a bubble trap chamber located in the downstream of the bubble trap flow path and in the upstream of the sensor unit and designed to trap bubbles; the liquid filling method comprising: forming an inlet in an area other than a specific section adjoining to and directly communicating with the bubble trap flow path in the pathway of the liquid; injecting the liquid through the inlet; and sealing the inlet after the injection of the liquid.
