NON-INSERTION NOZZLE FOR STERILIZING AND CLEANING BOTTLE CONTAINER AND METHOD OF STERILIZING AND CLEANING INNER SURFACE OF BOTTLE CONTAINER

摘要

A non-insertion nozzle (8) for container cleaning, having cleaning efficiency particularly high in sterilizing and cleaning a bottle container. Using the non-insertion nozzle (8) reduces the amount of use of cleaning fluid and cleaning time. The upper face of the non-insertion nozzle (8) functions as a liquid receiving surface (10), a stagnation wall (11) having a predetermined height is formed on the outer periphery of the liquid receiving surface (10), forming a stagnation recess (12), and nozzle holes (13) communicating with a fluid flow path of a nozzle stem (14) are formed at substantially the center of the liquid receiving surface (10) so as to incline in an outwardly spreading manner. The non-insertion nozzle (8) is placed under the opening of an inverted container (28) with a gap (H) in between and ejects sterilization fluid or cleaning fluid into the container from under the container opening (30).
