Ink cartridges having an air intake valve which is opened in response to the removal of a protection member from a case of the ink cartridge
Abstract:

A protective member is provided with a projection, which causes the manipulating rod to move so as to open the air intake valve, in response to a motion for detaching the protective member from an ink cartridge.
