<P>PROBLEM TO BE SOLVED: To provide a coating implement which can prevent a coating liquid from leaking or drying by a small urging force. <P>SOLUTION: A tip 12 for a coating implement 1 used for the coating implement 1 is equipped with a cylindrical member 15 and a valvular member 17, and the valvular member 17 seals an opening part 30, on the apex side, of the cylindrical member 15 by urging the valvular member 17 to the apex side with the help of an urging member 16. Further, a first tapered surface 31 and a second tapered surface 32 located nearer to the rear end side than the first tapered surface 31, are formed in the opening part 30 of the apex side. The opening part 30 of the apex side is sealed by bringing a tapered region 52 of the valvular part 17 and a ring member 17b into contact with these tapered surfaces 31 and 32, respectively. <P>COPYRIGHT: (C)2007,JPO&INPIT |
