Patent ID: 8177342

Claim:
A method for remanufacturing 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 remanufacturing method comprising: providing a liquid container structured to include: a first liquid chamber arranged to store the liquid therein and positioned to define a downstream direction from the liquid container to a liquid consuming device; a second liquid chamber located downstream of the first liquid chamber and arranged to be in liquid communication with the first liquid chamber and to store the liquid therein; a sensor unit located downstream of the second liquid chamber and arranged to receive therein a sensor for detecting a consumption level or a remaining level of the liquid; a liquid feeder located downstream of the sensor unit and arranged to supply the liquid stored in the first liquid chamber and in the second liquid chamber to the liquid consuming device; an air open structure, in fluid communication with the air outside the liquid container arranged to place the first liquid chamber in fluid communication with the outside air via an air communication path; a bubble trap flow path located upstream of the sensor unit and downstream of the second liquid chamber and designed to trap bubbles; and a bubble trap chamber located downstream of the bubble trap flow path and upstream of the sensor unit and designed to trap bubbles; forming an inlet in the second liquid chamber; injecting a liquid through the inlet; and sealing the inlet after the injection of the liquid.
