As the bottles go through the bottle washing machines the inside of each bottle is sprayed at various locations at each of which the bottle conveyor travels an arcuate path, the center of which is generally coincident with the center of the rotary spray pipe. The rotary spray pipe is provided with rows of aligned spray nozzles each of which lines up with the neck of a bottle in the conveyor as it passes over the spray area. A header surrounds the pipe at each nozzle location with a segment of the header removed to allow the nozzles to spray the adjacent bottles as the nozzles pass the cutout section. For the remainder of a revolution the nozzle is blanked off by the header. The bottles are always synchronized with the nozzles since the conveyor sprocket rotates with the spray pipe. A backflush pipe is fixed below and communicates with the header so water can be flushed through the nozzles in reverse direction for cleaning.
