Abstract
Perfections in valvular devices for aerosols, characterized by comprising a closure lining provided with an opening; a sealing cup; a spring that normally holds the cup in closing fit with the lower face of the lining; and a dispensing nozzle provided with a tubular stem that extends through the aforementioned opening, into the interior of the sealing cup; the dispensing nozzle can be operated to move the sealing cup of the closure fit with the garniture, to allow discharge of the contents of the container, and, further, because the tubular stem of the dispensing nozzle forms a perfect fit with the sealing cup and it has a longitudinal gauge slot preferably of uniform cross section, on its outer surface to allow the material released by the rupture of the closure between the sealing cup and the lining to circulate inside and through the stem.
