Abstract
The cartridge case of an ink cartridge has cover panels removably attached to both sides of a case core. A locking mechanism that can be disengaged and holds the cover panels to the case core forcibly elastically deforms the first latch plates of the cover panel, and engages or disengages the first protruding catch of the case core. Elastic deformation of the first latch plates is limited by the locking tab of the other cover panel, and as long as the other cover panel is not removed from the case core, the locking mechanism will not disengage and the one cover panel will not separate from the case core.
