Abstract
A reliable ink cartridge that reduce printing nonconformity even during high speed inkjet-recording with multiple nozzles by alleviating rapid external impact applied from the outside of the ink cartridge. Within a casing of an ink cartridge, a flexible bag forming an ink reservoir is accommodated. Between the surface of the flexible bag where a sheet member is bonded and a wall surface of the casing, a stress damping chamber is provided. The stress damping chamber communicates with the atmosphere outside the ink cartridge via an orifice formed on a wall surface of the casing.
Claims8
A liquid storage container comprising:
- a liquid reservoir adapted to store a liquid therein;
- a first spring member accommodated within the liquid reservoir and urging the liquid reservoir so as to maintain the interior of the liquid reservoir at a negative pressure;
- a casing having a wall and accommodating the liquid reservoir therein;
- a supply port formed on the wall of the casing and facilitating supplying the liquid in the liquid reservoir to the outside;
- and
- a stress damping unit provided between the liquid reservoir and the wall of the casing, the stress damping unit damping stress applied to the liquid reservoir.
