Abstract
Ink cartridge (10) for inkjet printers having a vent hole (17) between ink reservoir (20) and the environment (21), and having a valve (22) associated with an ink outlet (11), which valve is arranged to be brought against the action of a resilient element (6) from a closed position into an open position when the ink cartridge is inserted into the printer, and vice versa. The valve (22) associated with the ink outlet (11) is coupled in such a manner to a valve (23) associated with the vent hole (17) that, when the ink cartridge is inserted into the printer, ink outlet (11) and vent hole (17) are opened in succession, and vice versa when the ink cartridge (10) is removed from the printer.
