摘要： A method and apparatus for leak testing a container wherein the container such as a flexible or semi-flexible package is received in a closeable test cavity. A pressure differential is installed between the inside of the container and an enclosed space within the test cavity outside of the container. A change in the pressure in the enclosed space is detected. The closeable test cavity comprises a flexible wall whose shape adapts to the shape of the container at least when the pressure differential is installed. The flexible wall advantageously compensates for variations in head space and shape of the packages, as where the contents are not uniformally distributed within the package. The flexible wall can sealingly contact a portion of the container spaced from a container seal to permit detection of seal leaks. A gas permeable, flexible screen can be employed between the container and the flexible wall to permit leak detection of leaks in the container beneath the flexible wall.
