PURPOSE:To provide a liquid agent coater equipped with a valve mechanism opening a valve by pressing a coating tip to a surface to be coated at the time of coating, excellent in valve operation stability, good in user's convenience, not generating the irregularity of coating capacity at every product, easy to assemble and produce and suitable for automatic assembling and compactification. CONSTITUTION:A coating tip cylinder 2 is fitted to the mouth part 1a of a liquid agent container and an annular valve seat 6 is formed to the inner periphery of the liquid agent outflow port 4c of the coating tip cylinder 2 and the valve disc 7 corresponding to the valve seat 6 is arranged so as to partially protrude from the outflow port 4c outwardly. A valve operation shaft 8 opening and closing the valve disc 7 by axial movement and a coned disc spring 10 elastically energizing the valve operation shaft 8 to the closing side of the valve disc 7 are provided in the coating tip cylinder 2 and the valve disc 7 is opened by pressing the outwardly protruding part thereof to a surface to be coated to lead out a liquid agent from the outflow port 4c. |
