It would be safer and much more environment-friendly if normal air, nitrogen or carbondioxyde could be used in aerosol packaging systems (such as spray cans) instead of adverse propellants, such as propane and butane. However, until now the application of compressed gases is limited. because their pressure drops dramatically during the outflow , resulting in a poor and inconsistent spray-pattern of the product. This project is set up to research, develop and manufacture a prototype of an innovative Pressure Control Device (PCD) for spray can applications, which fits into the spray valve and uniquely ensures a consistent pressure during use. This opens the way to apply any gas as a propellant (e.g. normal air) in aerosol packaging systems.
The PCD would solve the problems of:
i) the greenhouse effect of traditional propellants and;
ii) the flammable and explosive nature of traditional propellants;
iii) loss of spray quality due to pressure drop if instead of traditional propellants compressed gases are used. Furthermore, the proposal addresses research to and development of a high-speed automated assembly method.
