AI Technical Summary
Technical Problem
In image recording apparatuses, the purge process using negative pressure leads to air mixing with waste ink, reducing the amount of waste ink that can be stored and inefficient use of the liquid container.
Method used
A liquid container design with a pouch and storage chamber, where the pouch is filled with liquid and separated from the storage chamber, featuring a spout, atmospheric communication hole, and an indicator to monitor liquid levels, ensuring efficient storage and separation of liquids.
Benefits of technology
The design allows for efficient storage of liquid in both the pouch and storage chamber, minimizing air mixing and enabling effective waste ink management.
