Three major parts: the can, the valve and the actuator or button. The can is most commonly lacquered tinplate or a steel with a layer of tin)
and may be made of two or three pieces of
metal crimped together. Aluminum cans are also common and are generally used
for more expensive products. The valve is crimped to the rig of the can, and
the design of this component is important in determining the spray rate. The
actuator is depressed by the user to open the valve; the shape and size of the
nozzle in the actuator controls the spread of the aerosol spray.
