摘要：
An ink jet cartridge including a case, in which the bottom portion where an ink jet recording head is disposed projects, and a lid for covering the top surface thereof. In an ink containing chamber defined by the these case and the lid, there is provided an absorber. The lid is configured so that ribs provided directly over the projecting bottom are higher than the other ribs, and so that the lid can be used for different types of cartridge. In a black cartridge, the pertinent ribs perform the function of effectively bringing the absorber into pressure contact with an ink introducing section. In a color cartridge, the pertinent ribs perform the function of restraining the height of the top surface of the absorber disposed on the projecting bottom portion to a position lower than that of the top surface of each of the other absorbers.
