  • Patent number: 10697850
    Abstract: A method for testing a container (11) having an interior volume (12) for tightness, comprising the following steps: providing the container (11) in a pressure chamber (10) and reducing pressure within the pressure chamber (10) or increasing pressure within the container (11) as far as a predefined test pressure, ascertaining a pressure profile (100) within the pressure chamber (10) over time, comparing the pressure profile (100) to a reference profile (200) in order to determine whether a leak is present within the container (11), wherein ambient conditions of the container (11) and/or the pressure chamber (10) are monitored and the reference profile (200) is adapted to changing ambient conditions.

  • Patent number: 10641678
    Abstract: The invention relates to a testing device for testing the tightness of containers (2), comprising a supply unit (3) for supplying the containers (2), a testing unit (4) for testing the tightness of the containers (2), a diverting unit (5) for diverting tested tight containers (2), and a discharge unit (6) for discharging containers (2?) tested to be untight in the testing unit (2). The testing unit (4) has at least one individual testing chamber (42) for testing individual containers and at least one multiple testing chamber (41) for receiving a plurality of containers in order to simultaneously test multiple containers (2). The testing device also comprises a control unit (10) which is designed to supply possibly untight containers (2?) which have been discharged by means of the discharge unit (6) from a multiple testing chamber (41) individually back into an individual testing chamber (42) in order to carry out an individual test of said containers.

  • Patent number: 10545068
    Abstract: The present invention relates to an arrangement for testing the tightness of a container (2), comprising a testing chamber (3), in which the container (2) which is to be tested can be arranged, also comprising a pressure-altering device (5), in order to alter a pressure in the testing chamber (3) relative to a pressure in the container (2), further comprising a differential-pressure sensor (4) for determining a pressure difference between a reference pressure in a reference chamber (6) and a pressure in the testing chamber (3), and additionally comprising a valve (7) having a closing element (70), a first sealing seat (71) and a second sealing seat (72), wherein the first sealing seat (71) comprises a first sealing element (11, 21) for sealing the reference chamber (6) in relation to an antechamber, and wherein the second sealing seat (72) comprises a second sealing element (12, 22) for sealing the testing chamber (3) in relation to the antechamber (8).
