An aerosol spray cap 1 is discussed, which comprises two separate pieces, those of a base member 10 and a rotatable twist ring 20. The base member 10 is formed as a single cast piece for removably attaching to the top of an aerosol canister, and provides an actuator button which is integrated with the fluid passageway. This integrated fluid passageway and actuator button 11 interacts with the fluid out pipe of the aerosol canister, and so allows actuation of the aerosol. The rotatable twist ring, provides a means whereby the movement of the integrated fluid passageway and actuator button 11 is prohibited, thereby locking the operation of the aerosol.
