摘要： PROBLEM TO BE SOLVED: To achieve the following requirements: various sizes of dots are required when a dotted drawing, a poster and other various kinds of decorative items are prepared and in this case, a plurality of conventional dotting pens are normally required so that the size of dots can be changed, and therefore, a single dotting pen capable of drawing in various sizes of dots is desired. SOLUTION: The rear part of a relay refill comes into contact with the internal ink part of a writing utensil body and the forward part of the relay refill is protruded from the writing utensil body. Further, the tip part of the relay refill is wrapped with a cylindrical soft elastic material with interconnected cells and the forward part of the soft elastic material is curved. In addition, a space is formed in the connection part between the cylindrical soft elastic material with interconnected cells and the relay refill.

摘要： PROBLEM TO BE SOLVED: To lessen the development of a trouble on the action of a valve element by a method wherein the sedimentation of an ink pigment in the periphery of the valve element controlling the supply of an ink to a pen core is reduced. SOLUTION: In a writing utensil 1, in which the ink in an ink chamber 2 is fed to the pen core 5 by the axial pressing of the ink core 5 and which is equipped with a valve seat 91 lying between the ink chamber 2 and the pen core 5, a valve element 6 exchanging a close position, at which the cutting-off of the pen core 5 from the ink chamber 2 is realized through the abutting of the valve element 6 against the valve seat 91, for an open position, at which the communication of the pen core 5 with the ink chamber 2 is realized through the separation of the valve element 6 from the valve seat 91, a press spring 8 energizing the valve element 6 towards the tip side of a penholder 3 and a holding member 7 for holding the valve element 6 and the press spring 8 so as to make the valve element 6 axially shiftable, the holding member 7 has a communicating passage 11 communicating its interior with the ink chamber 2 and the valve element 6 has flow passage controlling part 66, which controls the circulation of the ink in the communicating passage 11 much more under its close position than that under its open position.
