Problems solved by technology

[0006] However, with the above-mentioned ink cartridge, the dark ink settled in the lower ink storage part is first supplied to the upper ink storage part through the communication flow path, and then the light ink is supplied after the dark ink is used, so there is a possibility of supplying to the inkjet system. The problem of uneven density of ink in the recording device
[0007] In addition, although the above-mentioned patent document 1 describes the structure in which the flow path is provided on the vertical portion and the horizontal portion of the L-shaped partition wall surrounding the communication flow path of the ink cartridge, in the above structure, due to the flow in the horizontal portion The communication flow path is provided directly below the flow path, so although the ink near the horizontal part will merge in the communication flow path, there will be no vertical liquid flow in the lower ink storage chamber that stirs the dark ink and light ink.

Abstract

An ink cartridge (500) mounted on a carriage reciprocating together with a coating head and supplying an ink in an atmosphere side storage part (270) and a supply side storage part (290) to the coating head. The atmosphere side storage part (270) and the first and second ink storage parts (292) and (294) are formed of the liquid storage recessed part (122) of a cartridge body (120) opened on one surface side opposed to the coating head in the reciprocating direction and a film (140) sealing the opened face of the liquid storage recessed part (122). Agitating mobile bodies (711) are stored in the atmosphere side storage part (270) and the second ink storage part (294) in a movable state.

Description

technical field [0001] The present invention relates to a liquid container for supplying liquid stored inside to the outside, for example, to a liquid container such as an ink cartridge suitable for being mounted on a carriage of an inkjet recording device and supplying ink stored inside to a print head. Background technique [0002] An inkjet recording device as an example of a liquid ejecting device mounts an ink cartridge storing ink, receives a supply of ink from the ink cartridge, and ejects the ink onto an object to be recorded for recording. [0003] The types of inks used in inkjet recording devices include dye-based inks and pigment-based inks. Pigment-based inks are obtained by uniformly dispersing dispersed particles such as pigments in a solvent and mixing them. This pigment-based ink has the following characteristics: if it is not printed for a long time and placed in the ink storage chamber without ink circulation, the dispersed particles will settle due to the...
