  • Fluid spraying system
    Patent number: 5713519
    Abstract: A 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.

  • Dispensing tube for directing the dispensing of fluids
    Patent number: 5711484
    Abstract: A fluid dispensing tube with fluid deflection surface that attenuates accumulation of solidified sprayed fluid. The fluid deflection surfaces can be used for mechanically breaking-up a fluid to enhance sprayability and uniformity or to create a fan spray, or both. The inlet end of the fluid dispensing tube can be fluidly connected to a container of fluid.
