Embodiment Construction

[0050] Figures 1A, 1B, 1C and 1D illustrate typical features of aerosol spray actuators and swirl cup nozzles used in the prior art, and these figures are described here to provide added background and context. Referring specifically to FIG. 1A, a typical transportable disposable propellant pressurized aerosol package 20 has a container 22 enclosing a liquid product 24 and an actuator 30 that controls a valve 32 mounted in a valve seat 34, A valve seat 34 is secured within a neck 36 of the container and is supported by a flange 38 of the container. Actuator 30 is depressed to open the valve and allow pressurized liquid to pass through nozzle 40 fitted with a spin cup to generate aerosol spray 42 . FIG. 1B shows the inner workings of a spin cup 44 used with a typical nozzle 40, where the four lumens 46, 48, 50 and 52 are aimed to produce four tangential flows indicated by the arrows in the lumens, which The tangential flow enters the spin chamber 60, where the continuously spu...

Abstract

A conformal, cup-shaped fluidic oscillator spray nozzle member (100, 200, 300, 400, 500) is configured to generate one or more oscillating sprays from fluid flowing into a substantially open proximal end and distally into a substantially closed distal end wall with one or more centrally located orifices defined therein. A multi-input, multi-output cup-shaped fluidic oscillator ( 200, 300, 400) is configured to generate a selected fluid spray from a plurality of (e.g., 2-8) fluid product inlets which are configured in interacting pairs and feed into a common interaction region of the fluidic nozzle geometry. Optionally, an outlet "A" can be positioned in the interaction region and allow for air entrainment into the interaction region or external oscillating spray streams to generate a foamed spray of fluid product.
