Abstract
An aspirator tray for connection to a liquid chemical spray device is disclosed. The tray includes a floor surrounded by a peripheral flange to define a dripped liquid chemical receiving and storage area. The tray connects to the spray device below the spray nozzles and is configured of sufficient size to catch any liquid chemical that may drip or dribble from the spray nozzles. A bottom drain opening is provided through the tray floor and vacuum tubing interconnects the drain opening with the top of the liquid chemical storage tank. A venturi is positioned with the main chemical supply outlet at the tank in a manner to provide suction forces through the vacuum tubing at all times when the spray device is in operation. In this manner, all liquid chemical materials caught by the tray will be automatically and continuously returned to the storage tank.
