Abstract: Disclosed is a method for treating containers, wherein the containers are transported along a predetermined transport path by a transport device and are treated in a predetermined manner by a first treatment device, wherein predetermined working parameters are used for the treatment of the container, wherein individual containers being inspected after their treatment and at least one variable characteristic of a quality of this container being determined, wherein that at least one identification information is generated by an inspected container and/or an inspection operation can be uniquely identified.

Abstract: A container handling system includes first and second rotary machines each comprising transport elements for transporting containers along first and second conveying paths, where the second conveying path is downstream of the first conveying path, a memory device, and a control device configured to determine during transport of a container that first and second transport elements transport containers in the first and second rotary machines and to store identifiers assigned to the first and second transport elements in the memory device, to ascertain whether an error is occurring during transport of the container through the container handling system, and to retrieve a stored identifier from the memory device if it is ascertained that the error has occurred.
