Abstract
To detect an unpressurized moving container, a fluid such as air is directed at the moving container. Thereafter, a level of deflection of the moving container resulting from the directed fluid is detected. An unpressurized container is indicated when the detected level of deflection exceeds a threshold level. Deflection may be detected by directing a pulse of air or a continuous stream of air against the container. The system is particularly useful in detecting unpressurized, thin-walled aluminum cans.
