摘要： A method of testing leakage and/or strength of paperboard-based containers is disclosed. The method comprises the steps of producing a sealed paperboard-based container (10); producing a through-opening (26) in a panel (18) of the container; and attaching a nozzle (30) to the through-opening. The method also comprises performing at least one of a first series of steps and a second series of steps. The first series of steps comprises: increasing pressure in the container by injecting a gaseous fluid into the container via the nozzle until a predetermined, first pressure value is obtained in the container; closing the nozzle preventing gaseous fluid from entering or exiting the container via the nozzle; after closure of the nozzle, measuring a second pressure value in the container; and using a difference in pressure between the first pressure value and the second pressure value as a measure of leakage of the container. The second series of steps comprises: increasing pressure in the container by injecting a gaseous fluid into the container via the nozzle until the container fails; measuring the maximum pressure value obtained in the container prior to the container failing; and using the maximum pressure value as a measure of the strength of the container. An associated apparatus and system is also disclosed.

摘要： A filling machine (100) is disclosed having a processing unit (600) including a processing station (612, 614, 616) and a conveyor system (601) configured for conveying container precursors through processing station. The conveyor system has comprising a plurality of shuttles or carriers (602) configured for carrying the container precursors along a track (604) through the processing station and a shuttle propulsion system allowing each shuttle to be individually propelled along the track. A corresponding method is also disclosed.
