ABSTRACT:
An ink connecting line from an ink printing head is docked on a container with a hollow needle passing through a rubber-elastic closure. A device for preventing re-use of the container for supplying ink to the 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. A hermetically closing cover device is provided inside the container for an insertion region of the hollow needle and can be tripped irreversibly through the use of the hollow needle the first time it is inserted. Once the hollow needle has been pulled out, ink can no longer flow out even if the needle is reinserted.
