Abstract
PURPOSE: To enable use of volatile ink without cap by keeping the inside of a barrel airtight by inserting a closing plug into a writing tip hole of a pen when a writing unit is in a state stored in the barrel.
CONSTITUTION: For storing a writing part, whose writing tip is protruded from a writing tip hole 4, a cap 20 is turned for moving a 1st projection 18 on a connecting part 16 upward guided by a 1st operation hole 38 and a 2nd projection 26 on a closing member 6 downward guided by a 2nd operation hole 40. Then the writing part 1 is stored in a barrel 2, and the projection 18 of the connecting part 16 becomes on the top of the 1st hole 38. The closing plug 8 of the closing member 6 closes the hole 4 and maintain the inside of the barrel airtight to enable use of volatile inks for writing tools. When the writing part is stored in the barrel, the ink is not vaporized and does not stick to the other objects accidentally without troublesome operation of on and off of the cap.
