    摘要: Method and apparatus for leak testing a closed container with at least one flexible wall area, whether or not the container undergoing leakage testing is is filled with a product or not. A biasing member is moved towards and onto the flexible wall area in order to apply a predetermined force and the accompanying reaction forces are monitored over time. The instant invention of this leakage or integrity testing system constitutes an improvement over conventional prior art pressure monitoring sytems by instead monitoring a biasing force applied by such biasing member to such flexible wall area at different times over a testing cycle, whereby storage of two biasing force values at different times allows the later processing of a difference signal that is generated by using two measured force signals over time to thus result in both a leak indicative signal and an updated compensating zero offset signal. Furthermore, the moving of the biasing member may be done at a constant rate or predetermined rate, or the moving accomplished by establishing a pressure difference between the inside of the container and its ambient surroundings, such as may be done by evacuating such surroundings by application of vacuum.

    摘要: A method and device for testing containers, the method calling for a difference in pressure to be generated between the pressure inside the container and the pressure immediately surrounding the container, the behavior of one of these pressures permitting the gas tightness of the container to be assessed. A pressure value is stored and subsequently compared with one of the pressures, the stored pressure value being stored electronically and compared with at least one value of the output signal from a pressure sensor. The container is housed in an enclosure which is connected to a pressure or suction line, and a pressure-value storage unit, a comparator unit and a pressure sensor are associated with the pressure or suction line.

    摘要: To test a closed container having at least one flexible wall area in order to determine a leakage by an increasing of the inner volume of the container and a measuring of a correspondingly caused changed measured value, at least one outer wall area of the container is exposed to a medium having a pressure which is greater than a pressure produced by the increase of the volume of the container if such has no leakage. The increase of the volume can be made by a pneumatic or mechanical application of a force at a flexible wall area. The arrangement is specifically suitable when the wall of the container or its contents strive to self-seal a leakage spot in a wall area.
