Abstract

A multiple hole, preferably a two hole spray dispensing system and sprayer in which colliding streams of viscous fluid are dispensed to the atmosphere are provided. The spray dispenser includes a reservoir for storing a fluid product. An aerosol or manually pressurized dispensing system preferably a hand held dispensing system may be used. Liquid is delivered from the reservoir under pressure to a delivery passageway. A nozzle having two or more outlets to the atmosphere is mounted to the delivery passageway to provide colliding streams of liquid. Baffles are provided to disrupt the flow of liquid in the stream prior to the collision of the streams to provide an improved spray pattern.

Claims

1. A spray dispenser for dispensing and atomizing liquid comprising:

a) a reservoir for storing a viscous fluid;

b) means to deliver viscous fluid from said reservoir to a delivery passageway;

c) a nozzle in fluid communication with said delivery passageway having a first and second nozzle outlet providing a first and second intersecting stream of viscous fluid exiting from said first and second nozzle outlets;

d) a first and second baffle centrally located within the nozzle between the first and second nozzle outlets;

said first baffle extending across a portion of said first viscous fluid stream;

said second baffle extending across a portion of said second fluid stream;

e) said viscous fluid streams intersecting with one another after contacting said baffles;

so that a portion of the flow of the viscous fluid in said first and second viscous fluid streams is disrupted prior to the intersection of the viscous fluid streams.

2. The spray dispenser according to claim 1 wherein the baffles are attached to said nozzle.

3. The spray dispenser according to claim 1 wherein said baffles are integral with said nozzle.

4. The spray dispenser according to claim 1 further comprising:

a third baffle spaced apart from said first and second baffles for contacting said first intersecting stream.

5. The spray dispenser according to claim 4 further comprising:

fourth baffle spaced apart from said first, second and third baffle for contacting said second intersecting stream.

6. The spray dispenser according to claim 5 wherein

said first and second intersecting streams having an interior side and an exterior side opposed to said interior side;

said first and second baffles contacting said first and second intersecting streams on the interior sides of said first and second intersecting streams.

7. The spray dispenser according to claim 6 wherein said third and fourth baffles contacting said third and fourth intersecting streams on the exterior sides of said first and second intersecting streams.

8. The spray dispenser according to claim 1 wherein said first and second baffles are provided by opposed surfaces of a post.

9. The spray dispenser according to claim 8 wherein said post has a circular front surface.

10. The spray dispenser according to any one of claims 1-3 and 5-9 wherein the spray dispenser is an aerosol dispenser.

11. The spray dispenser according to any one of claims 1-3 and 5-10 wherein the spray dispenser is a hand pump sprayer.

12. The spray dispenser according to any one claim 1-3 and 5-10 wherein the spray dispenser is an aerosol sprayer having a compressed gas propellent selected from the group consisting of carbon dioxide, nitrogen and nitrous oxide.

13. A spray dispensing system for viscous fluids comprising:

(a) a reservoir;

(b) a viscous fluid composed of vegetable oil or hair spray having a viscosity greater than about 60 cps stored in said reservoir;

(c) means to deliver said viscous fluid from said reservoir to a delivery passageway;

(d) a nozzle having a first and second nozzle outlet providing a first and second intersecting stream of viscous fluid exiting from said first and second nozzle outlets;

(e) a first and second viscous fluid baffle extending across a part of each viscous fluid stream to disrupt a portion of the flow of the viscous fluid in each stream;

(f) said viscous fluid streams intersecting with one another after contacting said baffles;

said first and second viscous fluid baffles centrally located within the nozzle between the first and second nozzle outlet;

said first baffle contacting a portion of said first viscous fluid stream and said second baffle contacting a portion of said second viscous fluid stream;

so that the flow of the viscous liquid in said first and second fluid streams is disrupted prior to the intersection of the viscous fluid streams.

14. The spray dispensing system according to claim 13 wherein the baffle is attached to said nozzle.

15. The spray dispensing system according to claim 13 wherein said baffle is integral with said nozzle.

16. The spray dispensing system according to claim 13 further comprising:

a baffle platform centrally located within the nozzle between the first and second nozzle outlet;

said baffle platform providing a first baffle located on a first exterior surface of said baffle platform and a second baffle located on a second exterior surface of said baffle platform;

said first baffle contacting said first viscous fluid stream and said second baffle contacting said second viscous liquid stream;

whereby the flow of the viscous liquid in said first and second liquid streams are disrupted prior to the intersection of the viscous fluid streams.

17. The spray dispensing system according to claim 13 further comprising;

a third baffle spaced apart from said first and second baffles for contacting said first intersecting stream.

18. The spray dispensing system according to claim 17 further comprising;

a fourth baffle spaced apart from said first, second and third baffles for contacting said second intersecting stream.

19. The spray dispensing system according to claim 18 wherein:

said first and second intersecting streams having an interior side and an exterior side opposed to said interior side;

said first and second baffles contacting said first and second intersecting stream on the interior sides of said first and second intersecting stream.

20. The spray dispensing system according to claim 19 wherein said third and fourth baffles contacting said third and fourth intersecting streams on the exterior sides of said third and fourth intersecting streams.

21. The spray dispensing system according to claim 13 wherein said first and second baffles are providing by a post.

22. The spray dispensing system on claim 21 wherein said baffle platform has a circular front surface.

23. The spray dispensing system according to claim 13 wherein said viscous fluid is a vegetable oil based cooking spray.
