Fluid spraying system

An apparatus for spraying a multiple component fluid system, comprising:

• at least a first and a second container for receipt of a first and a second fluid, respectively, the first and second containers including a rib and trough closure system constructed to open in response to pressure within the first and second containers in excess of a predetermined amount;
• a spray applicator for controlling the flow of pressurized air to a nozzle assembly, the nozzle assembly comprising;
• a first atomizing portion defining a passageway in fluid communication at a first end with the pressurized air of the spray applicator, the passageway having a first cross-sectional area proximate the first end, a second cross-sectional area less than the first cross-sectional area proximate a middle portion, and a first fluid inlet port between the middle portion and a second end so that a reduced pressure condition is created in the passageway proximate the first fluid inlet port when pressurized air is supplied to the nozzle assembly;
• a second adjacent atomizing portion defining a passageway in fluid communication at a first end with the pressurized air of the spray applicator, the passageway having a third cross-sectional area proximate the first end, a fourth cross-sectional area less than the third cross-sectional area proximate a middle portion, and a second fluid inlet port between the middle portion and a second end so that a reduced pressure condition is created in the passageway proximate the second fluid inlet port when pressurized air is supplied to the nozzle assembly;
• and
• at least a first tube fluidly connecting the first fluid in the first container with the first fluid inlet port of the first atomizing portion and a second tube fluidly connecting the second fluid in the second container with the second fluid inlet port of the second atomizing portion so that the first and second fluids are capable of being drawn through the first and second fluid inlet ports and expelled in first and second atomized streams from the second ends of the first and second atomizing portions, respectively, when pressurized air is supplied to the nozzle assembly, the first and second atomizing streams being capable of overlapping to intermix the first and second fluids.

A spray applicator system comprising:

• a first atomizing portion defining a passageway in fluid communication at a first end with a source of pressurized air, the passageway having a first cross-sectional area proximate the first end, a second cross-sectional area less than the first cross-sectional area proximate a middle portion, and a first fluid inlet port between the middle portion and a second end so that a reduced pressure condition is created in the passageway proximate the first fluid inlet port when pressurized air is supplied to the nozzle assembly, a portion of the passageway of the first atomizing portion between the middle portion and the second end having a generally frusto-conical shape with a base of the frusto-conical shape proximate the second end, whereby the reduced pressure condition is sufficient to draw a fluid through the first fluid inlet port and to expel an atomized stream from the second end of the first atomizing portion;
• a second atomizing portion comprising a passageway having a third cross-sectional area proximate a first end, a fourth cross-sectional area less than the third cross-sectional area proximate a middle portion, and a second fluid inlet port between the middle portion and a second end so that a reduced pressure condition is created in the passageway proximate the second fluid inlet port when pressurized air is supplied to the second atomizing portion, a portion of the passageway of the second atomizing portion between the middle portion and the second end having a generally frusto-conical shape with a base of the frusto-conical shape proximate the second end, the first end of the second atomizing portion fluidly connected proximate to the first end of the first atomizing portion by an angled connector, the angled connector retaining the passageway of the first atomizing portion in a fixed relationship with respect to the passageway of the second atomizing portion whereby the first and second atomizing portions are capable of generating overlapping first and second atomizing streams;
• and
• first and second containers in fluid communication with the first and second fluid inlet ports, respectively, the first and second containers including a rib and trough closure system constructed to open in response to pressure within the first and second containers in excess of a predetermined amount.

A method of applying a multiple component fluid system, comprising the steps of:

• providing pressurized air to a nozzle assembly, the nozzle assembly having a first atomizing portion defining a passageway in fluid communication at a first end with the pressurized air, the passageway having a first cross-sectional area proximate the first end, a second cross-sectional area less than the first cross-sectional area proximate a middle portion, and a first fluid inlet port between the middle portion and a second end;
• creating a reduced pressure condition in the passageway proximate the first fluid inlet port when pressurized air is supplied to the nozzle assembly;
• providing pressurized air to a second adjacent atomizing portion, the second atomizing portion defining a passageway in fluid communication at a first end with the pressurized air, the passageway having a third cross-sectional area proximate the first end, a fourth cross-sectional area less than the third cross-sectional area proximate a middle portion, and a second fluid inlet port between the middle portion and a second;
• creating a reduced pressure condition in the passageway proximate the second fluid inlet port when pressurized air is supplied to the nozzle assembly;
• drawing first and second fluids into the first and second fluid inlet ports from first and second containers containing first and second fluids, respectively, the first and second containers including a rib and trough closure system constructed to open in response to pressure within the first and second containers in excess of a predetermined amount;
• and
• expelling first and second atomized streams from the second ends of the first and second atomizing portions, respectively, when pressurized air is supplied to the nozzle assembly whereby the first and second atomized streams are capable of overlapping to intermix the first and second fluids.
