摘要： A device for preventing re-use of a container for supplying ink to an ink printing head has high functional security, only allows the use of new fresh ink containers prescribed by the printer manufacturer and suppresses the use of fresh ink containers that have already been in operation and were then refilled. An ink connecting line from the ink printing head to the fresh ink container is docked in a known manner through the use of a hollow needle that is passed through a rubber-elastic closure. Two electrodes in the bottom of the fresh ink container are also part of an ink exhaustion detector in a known manner. A cover device for at least one electrode can be tripped irreversibly through the use of the hollow needle the first time it is inserted.
