A container for storably receiving an ink jet cartridge for an ink jet recording apparatus includes a recording head section for discharging ink from a plurality of ink discharging orifices and an ink storing section. The container includes a holding member for firmly holding the ink jet cartridge at a predetermined position in the container, a capping member for sealably covering the ink discharging orifices therewith while the ink jet cartridge is firmly held in the container, a pump for sucking ink from the ink discharging orifices for activating the ink jet cartridge, and a waste ink chamber having an ink absorber received therein for retaining the sucked ink. In addition, the container includes a squeezing member adapted to be actuated from the outside for deforming the ink absorber and an ink drain port. Additionally, the container includes a connecting member for operatively connecting a case cover to a piston rod of the pump and a mechanism for releasing the connecting member from the connected state when a very large magnitude force is applied to the connecting member.
