When the inner surface of containers conveyed in an inverted posture is sterilized, the sterilization efficiency can be increased, the amount of sterilizing fluid used can be reduced, the sterilization time and washing time can be shortened, the number of drive components of the apparatus can be reduced and the apparatus can be simplified and reduced in cost. A non-inserted nozzle 20 is disposed at a distance of 1-50mm below the lower end surface 52 of a mouth of a container conveyed in an inverted posture, the sterilizing fluid is mixed with air and the sterilizing fluid is atomized and sprayed intermittently from the non-inserted nozzle toward the inside of the container.本發明的容器殺菌和洗淨方法及其裝置,係對在倒立狀態下搬送的容器內面施行殺菌,提高殺菌效率而減少殺菌流體使用量,同時可縮短殺菌時間及洗淨時間,並減少裝置之驅動部以簡單裝置、降低成本。在以倒立姿勢搬送的容器口部下端面52之下方,離開1~50mm的狀態配置有非插入噴嘴20,從非插入噴嘴朝容器內面使殺菌流體與空氣混合而呈微細粒子化,並間歇地朝容器內部噴射。20...殺菌步驟所使用的非插入噴嘴21...噴嘴桿22...噴嘴套管23...蓋體24...噴嘴口部25...殺菌流體流路27...空氣供應路28...殺菌流體噴射孔30...空氣噴射孔31...混合室32...銳孔50...瓶子51...容器(瓶子)口部52...口部下端面
