ABSTRACT:
A writing implement comprises a tubular barrel containing an ink, a writing ball fitted in a socket formed in the tip of the barrel, and an ink stirring member sealed in the barrel so as to be movable to stir the ink so that the precipitated components of the ink are dispersed when the barrel is shaken. A helical spring is disposed within the barrel at a position near the writing tip of the barrel so that the front end thereof is in contact with the writing ball to press the ball resiliently forward and the back end thereof can be struck by the stirring member. When the barrel is shaken so that the stirring member may apply shocks to the back end of the helical spring, the helical spring vibrates slightly and the slight vibrations of the helical spring disperse the precipitated components of the ink and secure smooth ink flow.
