Abstract

The present invention provides a liquid container, which can eliminate air bladder even though the air bladder generating in the cavity of the liquid residual capacity sensor, so as to prevent the liquid residual capacity sensor from measuring by accident due to the air bladder. The container body (10) comprises: liquid containing chambers (370, 390, 430), for holding liquid; and liquid residual capacity sensor (31), for detecting the presence or absence of liquid based on residual vibration by piezoelectricity elements. A no-liquid-filled chamber (501) which is in communication with the outside of the container body (10), when casing the liquid container (1) through decompression and encapsulation, the no-liquid-filled chamber (501) becomes a deaeration chamber which contains negative pressure for deaeration, to eliminate the air bladder in the sensor by means of the decompression of the deaeration chamber.

Description

technical field [0001] The present invention relates to a liquid container for supplying liquid stored in a container body to a liquid consuming device. Background technique [0002] Examples of the liquid container and the liquid consuming device include, for example, an ink cartridge storing ink liquid, and an inkjet recording device in which the ink cartridge is replaceably attached. [0003] The above-mentioned ink cartridge generally has a structure in which, in a container body detachably installed in an ink cartridge mounting portion of an inkjet recording device, an ink containing chamber filled with ink is provided; The liquid in the ink storage chamber is supplied to the inkjet recording device; and the ink flow path communicates with the ink storage chamber and the ink supply hole. When the above-mentioned ink cartridge is installed in the ink cartridge installation part of the recording device, the ink supply needle provided in the ink cartridge installation par...
