Abstract
A pen for applying a color liquid whose sleeve part (1) includes an outlet port (3) for the color liquid, closable by a valve. The valve comprises a spring means incorporating at least one leaf spring (6, 6') or a disk spring, and a guiding element (4) pressed by the spring means against a sphere (5) which thereby is biased towards the outflow port (3). When the pen tip is pressed against an underlying substrate, the sphere (5) assumes an open position. The leaf or disk springs (6; 6') can be made of plastics and can be produced in one piece with the guiding element (4).
