Abstract:
A modular nozzle assembly for use with standard trigger sprayers 1, 300 has components which replace the standard nozzle cap 24, 320. A user selectable and user changeable fluidic plate or fluidic circuit member 152, 372 is configured to allow the user to configure a particular combination of components to create precise 2-D or 3-D spray pattern when spraying or dispensing a liquid product from a trigger sprayer or aerosol sprayer. A spray kit with a user configurable modular nozzle assembly and a method for configuring a trigger or aerosol sprayer for a selected spray pattern includes a reconfigurable nozzle assembly with a replacement nozzle cap 150, 346 having modular fluidic circuit insert element retaining features 170, 172 or 376 and at least one detachable modular fluidic circuit insert element 152, 372 which a user may attach to the fluidic modular element retaining nozzle cap150, 346.
Abstract:
For those spray applications that use a fluidic oscillator (4) of the type that generates a spray by having a pressurized liquid flow through the oscillator and exhaust into a surrounding environment, and where such an oscillator has a boundary surface (4b) which has fabricated into it a channel (4c) in the form of what is referred to herein as fluidic circuit, an improved enclosure (2) for this oscillator includes: a body (10) having an interior (13) and an exterior (12) surface, wherein a portion of this interior surface (13) is configured to attach to the oscillator boundary surface (4b) so as to form with the oscillator's channel (4c) an enclosed pathway through which the to-be-sprayed liquid may flow, and wherein a segment (23) of this interior surface is configured so as to yield specified properties of the resulting spray.
