Such, devices utilize a combination of Flair® technology, pre-compression valves and aerosol like pressurization of the dispensed liquid. Such a dispensing device has a main body comprising a pressure chamber, the latter being provided with a pressure piston and a pressure spring.

The piston chamber has both an inlet valve and an outlet valve. In a dispensing head a valve is provided to regulate the strength of the flow and preclude leakage. Once the liquid is sufficiently pressurized, it can be dispensed by a user opening an activation valve, such as by pressing on an activation button, and spray can be abruptly stopped by a user ceasing to push on such button. Or, for example, in alternate embodiments without an activation button, once the liquid is sufficiently pressurized, continuous spray occurs until the pressure chamber is emptied. By repeatedly pumping the trigger before the pressure chamber is fully emptied, continuous spray can be achieved. By designing the input volume to be amply greater than the volume of the pressure chamber, continuous spray with fewer pumping strokes can be implemented.
