AEROSOL CYLINDER Russian patent published in 1994 - IPC

FIELD: aerosol packages. SUBSTANCE: as one presses spraying cap 2, outlet valve 4 opens and working medium through pipe 6 enters outlet canal 5 and through jet is sprayed in atmosphere. Two step expansion of working medium provides high quality of its spraying without formation of conglomerates of solid particles. Volume, that becomes free inside cylinder capacity 7 is being filled by evaporating liquid gas and so cylinder inside pressure equaled to pressure of saturated vapour is maintained constant. In case of break of sealing of capacity 7 discharge of working medium is exercised in atmosphere in following way: during pressure in capacity 7 increases over critical one break of one of weakened areas, that have concave. Working medium expanding fills free volume of cavity 13 and having broken easily destructible film 16 pours into atmosphere. EFFECT: aerosol cylinder is used for spraying of different stuff. 10 cl, 10 dwg
