ABSTRACT:
In an automatic bottle washing machine, a nozzle spray system for spraying an internal bottom surface of a bottle or container that is rotatable about its central vertical axis. The nozzle spray system includes a nozzle body having a centralized bore for receiving pressurized fluid, a plurality of discharge orifices located in a staggered, spaced apart pattern on the surface of the nozzle body, and a plurality of elongated microbores to connect a respective one of the plurality of discharge orifices to the centralized bore. When the nozzle body is positioned within an invertedly positioned bottle, cleaning fluid is discharged from the plurality of discharge orifices in well focused jets toward adjacent regions of the internal bottom surface of the bottle. Simultaneously, the bottle is caused to rotate about its vertical axis so that the combination of the rotation of the bottle and the impingement of the well focused fluid jets enable the mechanical peeling off of the residual layers of grime located at the bottom surface of the bottle.
