PROBLEM TO BE SOLVED: To solve the problem that it is difficult to performing adjustment over the whole range of large aperture change, fine precision change or long-term continuous emission, or the like, in a communication passage for communicating ambient air with content such as fragrance, deodorant, or repellent which are conventional objects stored in a container.SOLUTION: A ventilation amount changing device for a gas passage performs gas divergence of a component of stored content around a container according to adjustment in a range from subtle divergence to intense divergence, regardless of magnitude change of the storage container, using the same main member, and over a short term or over the long term.COPYRIGHT: (C)2016,JPO&INPIT【課題】 従来の容器内収納物である芳香剤・消臭剤・忌避剤等の内容物と外気とを連通する連通路は、大開度変更や微細精密変更や長期間連続放出等の、全範囲に亘る調整が難かしかった。【解決手段】 この発明は、ほのかな発散から強烈な発散まで、収納容器の大小変更に係わらず、主要同部材でもって、容器廻りに短期または長期にと調整に応じて収納内容物の成分を気体発散する、気体通路の通気量変更具である。【選択図】 図1
