摘要

The apparatus (1) has an elongate ink containment chamber (2) that is provided with constant cross section over length. A reciprocating piston (5) is accommodated within the ink containment chamber. An ink discharge channel (8) is extended from ink containment chamber to working end (6) of the apparatus. Color ink within the ink containment chamber is ejected out via the ink discharge channel, while applying force over the reciprocating piston.
