ABSTRACT:
The present invention relates to valves for pressurized containers used for atomizing products such as alcoholic or aqueous lotions, such as, pharmaceutical products.
According to the invention, a caliber reducer (7) is disposed at the outer end of the discharge tube (3).
By limiting the dischage rate it is possible to prevent the formation of an undivided jet or solid discharge stream and to control the atomization process when pressure is removed from the button.
