Method and apparatus for dispensing fluid compositions

A handheld fluid dispensing system comprising:

• a drive motor;
• a header;
• a plurality of fluid reservoirs;
• a plurality of pump assemblies commonly driven by said drive motor, wherein a first and a second of said pump assemblies are in communication with a first and a second of said fluid reservoirs, respectively;
• a plurality of valve assemblies each including an inlet channel in communication with a first portion of one of said pump assemblies, outlet channel in communication with said header, recirculation channel in communication with a second portion of said one of said pump assemblies, and including a magnetic moving member for directing fluid from said input channel to one of said output channel and said recirculation channel;
• a control system coupled to said drive motor and said first and second valve assemblies, wherein said control system activates said drive motor and said first and second valve assemblies in accordance with a formulation to generate a fluid composition;
• and
• a handheld enclosure, wherein said drive motor, said plurality of fluid reservoirs, said plurality of pump assemblies, said plurality of valve assemblies and said control system are supportably received within said handheld enclosure.

A method of providing a regimen of customized fluid, the regimen including a plurality of compositions to be dispensed over time, comprising the steps of:

• providing a handheld fluid dispenser including a control system, a plurality of fluid reservoirs containing constituent fluids, a drive motor, and a plurality of valve assemblies;
• providing a regimen defining a plurality of composition formulas to define the plurality of compositions to be dispensed over time, the plurality of composition formulas including varying proportions of one or more of the constituent fluids;
• and
• activating the drive motor and valve assemblies with the control system to dispense the plurality of compositions from the fluid reservoirs over time in accordance with the regimen.

A method of providing a customized fluid, comprising the steps of:

• providing a handheld fluid dispenser including a drive motor, a control system, a plurality of valve assemblies, a plurality of fluid reservoirs each containing a constituent, and a handheld enclosure;
• generating a flow of a first constituent from a first of the fluid reservoirs;
• generating a flow of a second constituent from a second of the fluid reservoirs;
• directing the flow of a first constituent to a first of the valve assemblies, the first of the valve assemblies configured to selectively discharge or recirculate the flow of a first constituent;
• and
• directing the flow of a second constituent to a second of the valve assemblies, the second of the valve assemblies configured to selectively discharge or recirculate the flow of a second constituent;
• wherein the first and second of the valve assemblies are responsive to the control system for dispensing a fluid containing desired proportions of the first and second constituents.
