Nozzles and container cleaning system

Abstract

A nozzle and container cleaning system for rinsing and washing the interior of a flexible container. The system comprises a bulk bag dispenser having a concentric reducer and a pair of nozzles. The nozzles comprise an inner and outer cylinder, where the outer cylinder penetrates through the wall of the reducer, so that it communicates with the interior of the bag. The inner cylinder has a conduit and is slidably mounted within the outer cylinder and has an extended and retracted position. The conduit is connected to a fluid source which provides a pressurized fluid, either liquid or gas. The fluid is forced through a set of orifices in the inner cylinder and into the interior of the bag when the inner cylinder is between its two positions, thus expanding and rinsing the interior of the bag. The orifices have a notch positioned proximate to where the orifices exit the inner cylinder to better adjust the spray pattern of the fluid. As the inner cylinder moves between its two positions, a cap affixed to its top end lifts the bag so that more of the bag is exposed to the fluid. Furthermore, when the inner cylinder is in its retracted position, the combination of the cap and a plurality of seals prevents fluid from flowing into the reducer or into the interior of the bag.
