PROBLEM TO BE SOLVED: To provide an immediately effective chemical volatilizer capable of swiftly sucking up a chemical and naturally volatilizing the same.SOLUTION: Provided is a chemical volatilizer comprising a container and a volatilization body. The container has an opening at the upper part and stores a chemical at the inside. In the volatilization body, the lower end part is arranged at the inside of the container, the upper end part is inserted into the container via the opening so as to be exposed to the outside of the container, and the chemical is sucked up from the inside of the container. The volatilization body has: an outer surface and many stripe-shaped projections protruding from the outer surface and elongating to the sucking-up direction of the chemical. Many stripe-shaped fine grooves elongating to the sucking-up direction are formed among the many projections. The chemical volatilizer is composed in such a manner that the chemical sucked up by a capillary phenomenon along the many fine grooves is naturally volatilized to the outer space.SELECTED DRAWING: Figure 2COPYRIGHT: (C)2018,JPO&INPIT【課題】薬液を迅速に吸い上げて自然蒸散させることのできる即効性のある薬液揮散器を提供する。【解決手段】薬液揮散器が提供される。前記薬液揮散器は、容器と、揮散体とを備える。前記容器は、上部に開口を有し、内部に薬液を収容する。前記揮散体は、下端部が前記容器内に配置され、上端部が前記容器外へ露出するように前記開口を介して前記容器内に挿入され、前記薬液を前記容器内から吸い上げる。前記揮散体は、外側表面と、前記外側表面から突出し、前記薬液の吸い上げ方向に延びる多数の筋状の突起とを有する。前記多数の突起間には、前記吸い上げ方向に延びる多数の筋状の微細溝が形成される。前記薬液揮散器は、前記多数の微細溝に沿って毛細管現象により吸い上げられた薬液が、前記外部空間へと自然蒸散するように構成されている。【選択図】図2
