AI Technical Summary
Technical Problem
Ink containers and tanks with openings for gas and liquid flow paths close to each other risk ink or gas mixing, leading to reduced flow speed and prolonged ink replenishment times.
Method used
A liquid container design with separate and aligned flow paths for ink and air, featuring a valve and resilient member to control flow, ensuring smooth gas-liquid exchange and preventing leakage, with nozzle and communication portion designs that prevent mixing.
Benefits of technology
Ensures efficient and reliable ink transfer with minimal leakage, facilitating rapid replenishment and precise orientation alignment for smooth gas-liquid exchange.

Abstract
Provided are a liquid container and a system in which gas-liquid substitution occurs smoothly. An ink bottle 80 comprises: an ink chamber 89 for storing ink; a first flow path 107 extending from the ink chamber 89 to the outside; and an opening 95 for communicating the ink chamber 89 with the outside. A lower end 107L of the first flow path 107 is opened to the ink chamber 89. An upper end 107U of the first flow path 107 is opened to the outside. A lower end 95L of the opening 95 is opened to the ink chamber 89. An upper end 95U of the opening 95 is opened to the outside. In a first outflow direction in which the ink flows in the first flow path 107 from the lower end 107L toward the upper end 107U, the upper end 107U is located downstream of the upper end 95U of the opening 95.
