Understanding Patent US9714133B2
US9714133B2 describes a liquid dispensing device that mimics the spray quality of aerosol cans, without using harmful propellants. Commonly known as “Flairosol II,” this device relies on internal mechanical pressure to deliver a continuous, fine mist. It incorporates a pressure chamber, piston system, and dome valve to regulate flow and prevent leakage. Designed for use in consumer products such as cosmetics, cleaning supplies, and personal care, this technology aims to provide a cleaner and more controlled spraying alternative to traditional aerosol packaging.

Its four key features are
#1. Pressure chamber with spring mechanism: Stores liquid under pressure using a piston and spring to simulate the behavior of an aerosol.
#2. Dual-valve piston chamber: Controls intake and output of liquid, ensuring directional flow and preventing backflow.
#3. Dome valve at the outlet: Opens only when the internal pressure exceeds a preset level, allowing a spray and preventing drips.
#4. Continuous or activated spray options: Can operate via repeated trigger strokes or through a user-activated button to release a stored spray.
The device’s efficiency lies in its ability to deliver consistent spray patterns through internal pressurization without relying on external propellants. Its dome valve and precompression system ensure precise control over fluid release, making it both environmentally and functionally advanced.
