ABSTRACT:
Testing open-ended cartons to determine the centrifugal force at which the contents will move out an open end. A filled carton is positioned on a support and the carton is gripped at the end portions of the carton side panels and rotated. Upon reaching a rotational speed at which the carton can no longer hold the contents in place, the contents strike an end wall of the support, indicating that the carton has failed.
