METERED AND ACTIVATED SPRAYER DEVICES WITH AEROSOL FUNCTIONALITY ("FLAIROSOL II") Russian patent published in 2019 - IPC B65D83/14 B05B11/00 

FIELD: manufacturing technology.

SUBSTANCE: in the exemplary embodiments of the present invention, “Flairosol” dispensing devices may be provided. These devices use a combination of Flair^® technology, pre-compression valves and aerosol like pressurization of the dispensed liquid. Such a dispensing device has, for example, a main body comprising a pressure chamber, wherein the pressure chamber is provided with a pressure piston and a pressure spring. Additionally, the device has a piston and a piston chamber which draws the liquid from a container, for example, from the inner container of a Flair^® bottle, and fills the pressure chamber with this liquid when a user actuates the trigger in various compression and release strokes. Said piston chamber has both an inlet valve and an outlet valve, which serve to prevent backflow. Liquid exiting the piston chamber under pressure (supplied as the trigger is being repeatedly pressed by a user) enters a central vertical channel, which is in fluid communication with both the pressure chamber (above the pressure piston) and a dome valve provided near the outlet channel at the top of the dispensing/spraying head. Said dome valve has a preset pressure, wherein this valve opens and creates the possibility of spraying when the pressure of the liquid exceeds this preset pressure. If the pressure of the liquid falls below this preset pressure, the dome valve closes the outlet channel, which serves to regulate the flow strength and prevent any leakage. Alternatively, for example, in an activated embodiment, as soon as the pressure of the liquid is increased to a sufficient value, it can be dispensed by a user, creating the possibility of opening the dome valve by pressing the activation button which removes the blockage of the dome valve.

EFFECT: metered and activated sprayer devices with aerosol functionality (“Flairosol II”) are proposed.
