The contents are washed away without any leakage (air vent cleaning process). In this embodiment, the upper lid 6b and the air vent 7 are washed at the same time so that these washing times are the same. However, these washing times may be set individually.

  After the cleaning time of the upper lid 6b and the air vent 7 has elapsed, as shown in FIG. 6, the main nozzle 17 is in the lower limit position with the automatic valves B1 and B4 closed and the hot water injection from each nozzle temporarily stopped. And is disposed at a height approximately in the middle of the container body 2. Thereafter, as shown in FIG. 7, the automatic valve B1 is opened and hot water is supplied again to the main nozzle 17, and while the main nozzle 17 rotates, the hot water is sprayed to the entire inner surface of the container body 2, and the main nozzle 17 By appropriately moving up and down, the liquid content adhering to the inner surface of the container main body 2 is washed away without any leakage (container main body cleaning step). At this time, the hot water sprayed into the container main body 2 continuously flows through the extraction nozzle 8 so that the inside of the extraction nozzle 8 is also cleaned.

  After the cleaning time of the container body 2 elapses, the automatic valve B1 is closed, the hot water injection from the main nozzle 17 is stopped, and the vertical movement is stopped. After that, as shown in FIG. 8, the automatic valve B2 is opened and steam is supplied to the main nozzle 17, and the main nozzle 17 rotates and sprays steam to sterilize the inside of the container body 2 (steaming process). . The temperature rise state at this time is shown in the graph of FIG. In this embodiment, the inside of the container body 2 is sterilized by raising the temperature inside the container body 2 to about 90 ° C. in 2 minutes and further maintaining this state for 5 minutes. Note that steam injection may be performed while moving the main nozzle 17 up and down.

  After the steaming time has elapsed, as shown in FIG. 9, the automatic valve B2 is closed and the steam injection from the main nozzle 17 is stopped, and the automatic valve B3 is opened and the sterilized air passing through the sterilizing filter 28 is supplied to the air nozzle. 18 is introduced into the container body 2 to dry and cool the container body 2 (dry cooling process). The temperature drop situation at this time is shown in the graph of FIG. In this embodiment, the temperature inside the container body 2 is lowered to about 45 ° C. in 10 minutes.
