PROBLEM TO BE SOLVED: To eliminate use of a driver or the like and to simplify user's sorting by inserting a protrusion formed at a cap into a recess formed at a body or a tail plug, and separately disassembling the plug and the body by an easy means such as twisting, pulling or the like of the both. SOLUTION: A thickness of a protrusion 7 is set to a smaller size than a width of a recess 8, and to remove a tail plug 9 from a body 5, the protrusion 7 of the cap 6 is inserted into the recess 9, and the both are twisted. As a result, a part of the protrusion 7 is operated as a fulcrum, and the other portion lifts the plug 9, and hence, the plug 9 can be easily released from the body 5. Even if the protrusion 7 of the cap 6 is inserted into the recess 8 and the both are pulled, the plug 9 can be released from the body 5. Thereafter, a contained ink absorber contained in the body 5 can be taken out of the body 5, and the body can be easily sorted. The protrusion 7 is formed at the cap, and hence the user can simply sort them even without using a screwdriver or the like. |
