A process for the treatment or processing of containers is provided. The process includes automatically conveying the containers past a processing station for the treatment or processing by or through a conveying device and then inserting the containers into a transport or packaging container having a bottom, a circumferential side wall and an insertion opening opposite to the bottom. In some embodiments, a plurality of containers are placed on a flat supporting base so that the bottoms of the containers directly rest on the flat supporting base; the containers, while resting on the flat supporting base, are conveyed to a processing station by the conveying device to be treated or processed; and after the treatment or processing of the containers, the transport or packaging container is placed on the flat supporting base so that all the containers of the plurality of containers are accommodated in the transport or packaging container.
