PROBLEM TO BE SOLVED: To provide a gas diffusing body capable of continuously maintaining such effects as odor elimination, sterilization, and disinfection by diffusing a minute amount of gas over a long period of time while controlling a gas-permeable amount.SOLUTION: The package for storing chemical substances for producing a gas by reaction is formed of a resin sheet air permeable and liquid impermeable under a pressurized state. A gas-permeable member such as a nonwoven cloth having gas permeability and liquid absorption proerpty is disposed on the gas-permeable surface of the package to adsorb water content produced due to vaporization. Consequently, such effects as odor elimination, sterilization, and disinfection can be continuously provided comfortably over a long period of time.COPYRIGHT: (C)2012,JPO&INPIT【課題】 気体透過量を制御して、長時間に亘り微量のガスを放出することにより、消臭、殺菌、除菌等の効果を継続して維持し得る気体発散体を提供する。【解決手段】 反応してガスを発生する化学物質を収容する包装体を、加圧状態にあって通気性を有すると共に液体を通さない性質を備えた樹脂シートで形成し、更に気体透過面に通気性と吸液性を備えた不織布等の気体透過材を配して、気化に伴い発生する水分を吸着させることにより、快適な長時間に亘る、消臭、殺菌、除菌等の効果が継続して提供される。【選択図】 図1
