Abstract
An ink cartridge (10) having an ink reservoir which delimits in a first chamber (17) a free-ink volume (16) and in a second chamber (18) a capillary volume (15), there being an ink outlet (21) associated with the latter, and wherein for use of the cartridge both chambers (17, 18) are connectible to the external environment by way of air-admission openings (23, 24) which prior to use are closed by a removable or peelable film or so-called remove film (25). The air-admission openings (23, 24) are arranged with respect to one another in such a way that when the remove film (25) is peeled off it is always the chamber (18) delimiting the capillary volume (15) to which air is admitted first.
