A device 10 for atomising a liquid comprising a liquid reservoir 16 connected to an outlet nozzle 18. The device also has a moveable barrier 20, a space 13 containing a cylinder of pressurised gas 14, and a bleed channel 30 connecting the pressurised gas with the nozzle. In use, the device allows the pressurised gas to escape from the cylinder 14 into the space 13 so that the gas acts on the moveable barrier 20 which acts as a piston to force liquid 16 in the reservoir to pass through the nozzle inlet 32; the pressurised gas also enters the nozzle 18 via the bleed channel 30 to impart a swirling motion on the liquid as it passes through the nozzle 18, generating an aerosol spray 28 which is then emitted from the nozzle outlet 34. |
