  • MULTISTAGE CONTAINER LEAK TESTING
    Publication number: 20150177093
    Abstract: A coarse-fine two-stage leak detection is carried out on sealed, filled containers loaded into container holders or “pucks”. Failure of the first, coarse leak detection stage, e.g. a pressure-course or impedance or laser-absorption based leak detection stage, causes containers to be rejected together with their corresponding container holders. These are then separated, and the container holder is cleaned and dried before being returned to the system. Any leaking product from inside a grossly leaking container is thus retained within the container holder, thus reducing contamination of subsequent containers and their container holders, preventing such contamination from reaching the fine leak detection stage, e.g. a mass-spectrometer-based leak detection stage.

  • X-RAY DETECTION OF FLAWS IN CONTAINERS AND/OR IN THEIR CONTENTS
    Publication number: 20150144538
    Abstract: Method and system for x-ray detection of flaws in containers or their contents wherein containers are conveyed on a circular path around a central axis upon which an x-ray source is situated below the plane of the base of the containers. The x-ray source emits x-ray radiation obliquely upwards through the containers to a plurality of imaging x-ray detectors. Analysis of the images provided by these x-ray detectors determines the presence of a flaw in a container or its contents and is used to command a rejection mechanism to reject the container in question.

  • High-speed loading/unloading of objects
    Patent number: 9038257
    Abstract: The present invention relates to methods and an apparatuses for loading and unloading objects into/from corresponding cavities in holders at a high count rate. For loading, a plurality of objects are present on an object path which mutually converges with a holder path. For unloading, the object path mutually diverges from the holder path. Integration of this method and apparatus respectively into a method of manufacturing unleaky containers and a corresponding apparatus for leak testing containers is also proposed.

  • METHOD FOR LEAK TESTING AND LEAK TESTING APPARATUS
    Publication number: 20150107340
    Abstract: For leak testing closed containers (9) which are filled with a filling product containing at least one liquid component the container is introduced in a test cavity (1) which is evacuated at least down to vapour pressure of that liquid component. The pressure in the surrounding of the container (9) and thus within test cavity (1) is monitored. Monitoring is performed by a vacuum pressure sensor (7), whereas lowering pressure surrounding the container (9) is performed by a vacuum pump (5). Leakage is detected by monitoring a pressure change in the surrounding of the container which is due to evaporation of liquid emerging from a leak and being evaporated in the low pressure surrounding.

  • Method for manufacturing or testing metered-dose-ejection devices and testing apparatus therefore
    Patent number: 8336397
    Abstract: For testing metered-dose-ejection devices, whether the ejected dose accords with a rated dose, the device (1) is sealingly applied (26) to a test compartment (24) and upon machine manipulation on the device (M, 5) a dose is ejected into the test compartment (24). Pressure difference established by such injection and with respect to a pre-established reference pressure (30) in the test compartment (24) is monitored by a pressure sensor (32). The output signal (o) of this sensor (32) is indicative of the extent of the addressed dose.
