Therefore, between the filling and the closing of the container, cleaning of the mouth area of the container has hitherto been carried out, in which, for example, a flushing liquid jet is directed onto the mouth area of the container and this is then optionally dried by a blowing device or this is cleaned using a brush or a cloth, to remove the contents stored there.
