Abstract

Self-contained valve plug, for atomized liquid propulsion essentially characterized by comprising a lower tubular conduit in which a sphere is housed as well as the conduit for driving the liquid which is sealed by said sphere; next to the mouth of this duct there is an annular plate on which sits the lower plane of a closure cap of the mouth of the container, interspersed between it and the annular plate a suitable gasket, on the cap a guide bushing is conveniently arranged, integral, which covers the embouchure of the lower tubular conduit; through this guide bushing passes an upper conduit of suitable length, carrying at its upper end a spray nozzle head and at its lower end a piston, which is housed inside the inner conduit, which likewise it houses a tension spring that supports a lower staggering of said conduit and inside the piston, keeping it in a maximum position, limited by an external staggering of the upper conduit, which abuts the inner part of the guide bushing; the lower conduit is provided with holes that communicate its embouchure with the interior of the container, so that upon exerting a pressure on the atomizing head, the resistance of the spring is overcome, the piston decreasing, thereby establishing an overpressure inside the container. Container that determines an escape of air through the aforementioned orifices towards the atomizing head, simultaneously this escape with the ascent of the liquid which determines the expulsion by the capillary conduit that the nozzle of the atomizing head is provided.
