International ClassB05B 007/08AbstractA system and method for spraying single or multiple component fluid systems onto a surface. The spray applicator utilizes a venturi effect to independently draw fluids from separate containers, atomize the fluids and spray the fluids in a desired pattern onto a surface. The atomized streams generally overlap so that the fluids mix prior to contacting the target surface. In one embodiment, the fluids are retained in flexible containers separately connected to a spray applicator by flexible tubes. The flexible containers include a fitting for receiving a fluid draw tube and a releasable closure for expelling excess pressure within the container.Other References
