Abstract
An apparatus and method is provided for the detection of a leak between a container and a flexible cover secured about an opening in the container. The apparatus comprises a vacuum chamber for receiving the container, a pressure indicating sensor coupled to a controller; and a sensor support. The sensor is positioned on the sensor support wherein, in operation, the sensor is located in close proximity to the container cover such that when the container is within the vacuum chamber and subjected to a vacuum condition, gases within the container cause the cover to expand at the location of a leak between the cover and the container. Upon contact with the cover the sensor generates a signal received by the controller to indicate both the detection and the location of the leak about the opening in the container.
