The present invention relates to the field of ink jet printing technology. The cartridges, whose ink reservoir is in communication with the external environment through a venting hole, are subject to ink leakage when the external pressure changes significantly with respect to the external pressure after ink filling, in particular due to possible air bubbles trapped in the in the ink reservoir. The present invention provides a cartridge lid () with an expansion space () formed between an outer lid member () and an inner lid member (). The expansion space () is in communication with external environment through the venting hole () and has an inlet () through which ink is able to flow into the expansion space (). The present invention also provides a cartridge, an ink jet print head and an ink jet printer.
