PROBLEM TO BE SOLVED: To easily maintain the pressure of carbon dioxide gas in a gas cylinder by improving sealability between a gas outlet portion on the side of the gas cylinder and a gas inlet portion on the side of an opening and closing mechanism.SOLUTION: A cosmetic liquid sucked from a liquid container 10 is mixed with carbon dioxide gas supplied from a gas cylinder 8 through an opening and closing mechanism 5 and discharged from an ejection hole of a nozzle. The cosmetic liquid is sprayed from a spray port portion 6 by a negative pressure generated by the carbon dioxide gas. A holding case 16 can be moved and adjusted in a connecting direction X of the gas cylinder 8 relative to a support cylinder portion 15 by a female thread portion and a male thread portion, while the gas cylinder 8 remains supported by the holding case 16. A seal member between a gas outlet portion 24 on the side of the gas cylinder 8 and a gas inlet portion 13 on the side of the opening and closing mechanism 5 can be easily pressed with a proper force. Pressure contact of the seal member is regulated by a positioning function between the male thread portion of the support cylinder portion 15 and the female thread portion of the holding case 16, to prevent damages to the seal member.COPYRIGHT: (C)2014,JPO&INPIT【課題】ガスボンベ側のガス流出口部と開閉機構側のガス流入口部との間の密封性を高めてガスボンベ内の炭酸ガスの圧力を維持し易くする。【解決手段】ガスボンベ8から開閉機構5を通ってノズルの噴出孔から噴出する炭酸ガスで生じる負圧により液体容器10から吸引された化粧水が炭酸ガスと合流して噴霧口部6から噴霧される。ガスボンベ8を保持ケース16に支えたまま保持ケース16を支持筒部15に対しガスボンベ8の接続方向Xへ雌ねじ部及び雄ねじ部により移動調節することができる。そのため、ガスボンベ8側のガス流出口部24と開閉機構5側のガス流入口部13との間のシール部材を適切な力で圧接し易いとともに、支持筒部15の雄ねじ部と保持ケース16の雌ねじ部との間の位置決め機能によりシール部材の圧接を規制し、シール部材の損傷を防止する。【選択図】図1
