<P>PROBLEM TO BE SOLVED: To make it possible to efflux and supply a coating liquid to a coating body by means of writing pressure at writing and, at the same time, to avoid a fear for blowing out the coating liquid due to the rise of the pressure in a main body vessel through the attachment and detachment of a cap. <P>SOLUTION: In a liquid coating applicator, which is equipped with a coating body movable to and fro, a normally closed valve mechanism part by the pressing force of a coiled spring provided at the back of the coating body and the main body vessel containing the coating liquid therein at the back of the valve mechanism part under the state that the cap is firmly mounted to the tip of the vessel in order to tightly fit to the coating body, an inner cap, which is energized by a resilient body and made movable axially rearward, is provided inside the cap;. When the cap is firmly mounted, the inner cap moves under the condition that the coating body is tightly fitted into the inner cap. At writing, when the coating body moves rearward against the pressing force of the coiled spring by means of a writing pressure, the valve mechanism part is open, resulting in allowing to make the coating liquid supply from the tip side of the main body vessel to its coating body and, at the same time, the retreat of the coating body is checked by the retreated state of the coating body by the predetermined dimension. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
