PROBLEM TO BE SOLVED: To provide a nozzle which can be easily used only by being attached to a mouth part of a container in which material is stored and can put out the material in linear shape or in misty shape, to provide a coating device provided with the nozzle and to provide a method of using the nozzle.SOLUTION: A nozzle 10 is the nozzle 10 to be attached attachably and detachably to a mouth part B1 of a container B having a main body part which can be deformed by grasping power, the nozzle 10 includes a material outflow nozzle part 20 which has an outflow part 21 provided with an outflow opening 21a for causing material in the container B to flow out therethrough and a gas cap part 30 which has an opening part 31 forming a slit opening 31a on the circumference of the outflow part 21 and ejects gas from the slit opening 31a. Therein, in such a state that gas is supplied to the gas cap part 30, the material is caused to flow out from the outflow part 21, thereby, the material can be atomized, on the other hand, in such a state that gas is not supplied to the gas cap part 30, the material is caused to flow out from the outflow part 21 and, thereby, the material can be ejected in such a state that the material is not atomized.SELECTED DRAWING: Figure 3COPYRIGHT: (C)2018,JPO&INPIT【課題】材料が収容されている容器の口部に取付けるだけで手軽に使用でき、その容器内の材料を線状に出したり霧状に出したりすることができるノズル、そのノズルを備える塗布装置及びそのノズルの使用方法を提供すること。【解決手段】本発明のノズル10は、握力で変形可能な本体部を有する容器Bの口部B1に着脱可能に取付けられるノズル10であって、ノズル10は、容器B内の材料を流出する流出開口21aの設けられた流出部21を有する材料流出ノズル部20と、流出部21の周囲にスリット開口31aを形成する開口部31を有し、スリット開口31aから気体を噴出する気体キャップ部30と、を備え、気体キャップ部30に気体を供給した状態で流出部21から材料を流出させることで材料を噴霧することができる一方、気体キャップ部30に気体を供給しない状態で流出部21から材料を流出させることで材料を霧化しない状態で吐出させることができる。【選択図】図3
