Nozzle spray assembly

A nozzle and orifice assembly for cleaning an internal surface of a returnable bottle upon its return, prior to refilling, said internal surface having residual soiled locations, said bottle being rotatable about a vertical axis while simultaneously moving along a predetermined path in an inverted position, said nozzle system comprising:

• a nozzle body having a plurality of discharge orifices located in a predetermined spaced apart pattern on a surface thereof and a centralized bore for receiving pressurized fluid;
• a plurality of elongated microbores for connecting each respective orifice to said centralized bore for discharge of pressurized fluid therethrough;
• means for positioning said nozzle body within said inverted bottle and registering said nozzle body within said inverted bottle as said bottle moves along said predetermined path;
• wherein cleaning fluid under pressure is discharged in sharp, well focused jets determined by said spaced apart pattern of discharge orifices toward said internal surface and impinging at points upon said internal bottom surface in said spaced apart pattern such that when said bottle is rotated about its vertical axis, a mechanical peeling of residue at said residual soiled locations of said returnable bottle is accomplished by the combined action of said jets and said rotation.
