ABSTRACT:
Writing means using volatile ink, aqueous ink or the like writing comprises: a cylindrical body; a writing unit disposed at the lower surface of the body; and a cylindrical closing member rotatably and vertically movably attached to the lower end of the body. The writing unit includes an ink tank and a pen tip attached to the ink tank. The closing member is provided at the lower surface thereof with a cap unit for hermetically covering the pen tip and with a through-hole in which the pen tip is vertically movable. The rotation and vertical movement of the closing member with respect to the body selectively provides two states, i.e., one state where the pen tip is hermetically covered with the cap unit, and the other state where the pen tip projects from the pen-tip hole. Thus, according to the writing means of the present invention, the manipulation is simple, and there is no possibility that the ink is erroneously evaporated or the cap is lost. Further, since the pen tip is hermetically covered with the cap unit, the body inside is not required to have a complicated sealing structure.
