The key to dispersing ink without it drying in the pen, is the ball itself. The ball acts as a continuous cap to prevent the ink from drying as well as a mechanism for getting the ink onto the paper. A socket holds the ball between the ink reservoir and the paper. As you write, the ball turns and gravity forces the ink from the reservior onto the ball, which transfers it to the paper. The rolling mechanism also seals the ink in the reservior from the air so it does not dry out.
