The body (4) includes a system actuable to effect discharge of the substance from the nozzle assembly (2) and actuating means operably by a user to effect discharge. Preferably the discharge system comprises a spring-loaded air piston (68) actuable to inject air into the container (24) to cause discharge of the substance. In one embodiment a driving spring for the air piston is loaded with spring energy by the action of installing the nozzle assembly on the body, the driving spring thereafter being held in a cocked state until operating of the actuating means by the user to effect release of the spring energy to cause discharge. |
