PROBLEM TO BE SOLVED: To provide an anti-liquid-leakage structure in a spray device, for enabling smooth supply of liquid to a spray mechanism, and preventing the liquid from leaking when the spray device is inclined or falls.SOLUTION: A spray device includes: a nozzle for discharging carbon dioxide gas supplied from a gas cylinder 22; an on-off valve which opens and closes a flow path of the carbon dioxide gas supplied to the nozzle; a supply port opened close to a tip of the nozzle; and a liquid container 31 connected to the supply port. An air hole 33 is provided at an upper portion of the liquid container 31, and a check valve 34 is also provided to close the air hole 33. The check valve 34 is formed of a rubber-like elastic body and configured to always prevent leakage of a cosmetic liquid in the liquid container 31, and to suck air through the air hole 33 according to the negative pressure in the liquid container 31 when the spray device is in use. |
