PROBLEM TO BE SOLVED: To provide a head having directionality with a positioning function portion so that the body and the head are positioned based on the head regarded as a reference position. SOLUTION: A mouth cylinder piece 7 is raised on the upper end of a threaded cylinder wall 5 on/from which a cap 13 covering a head 3 is fitted/removed. A coating function portion is formed on the outer surface of a sloped top wall 8 closing the upper end of the mouth cylinder piece 7 and sloped in a given direction. A positioning projecting piece 12 is formed on the upper part of the threaded cylinder wall 5, where the projecting piece 12 does not hamper fitting/removal of the cap 13. With this positioning projecting piece, the position of printing relative to a body 2 is determined. COPYRIGHT: (C)2011,JPO&INPIT |
