  • Container leak detection
    Patent number: 10690564
    Abstract: There is provided a leak detection system for detecting breaches in sealed food containers. The leak detection system comprises air-sample testing equipment configured to test the composition of an air sample provided to the air-sample testing equipment. At least one pressing member is provided configured to, in use, apply pressure to the sealed food container located in an air-sampling region. At least one air-sampling port is located in the air-sampling region. An air sample conduit is provided extending between the at least one air-sampling port and the air-sample testing equipment. In use, the at least one air-sampling port takes an air sample from the air-sampling region at least during or after the at least one pressing member applies pressure to the sealed food container in the air-sampling region and communicates said air sample through the air sample conduit to the air-sample testing equipment.
