Abstract
A dispensing head for emitting an atomized spray of liquid droplets includes an actuator and a nozzle insert. The actuator includes a gas duct and a liquid duct and may be attached to a container housing a propellant gas and a liquid product. The nozzle insert includes at least one modular structure that can be installed in an actuator socket on the actuator. The nozzle insert includes a pressure cap defining a pressure chamber having an exit orifice. A liquid conduit is disposed in the pressure chamber and defines a liquid supply channel having a liquid supply channel exit opening. The nozzle insert is configured to form a reflux cell in the liquid supply channel upstream of the liquid supply channel exit opening to achieve flow blurring interaction between the liquid product and the gas propellant.
