  • Package tester for testing package integrity
    Patent number: 6041646
    Abstract: A package tester is provided which uses a rotating platen (10) to convey packages under test between first and second test positions. A compressive load (22) is applied to a package (50) before it reaches the first test position and travels with and remains in contact with the package as it moves towards the second test position. Thus, the package is kept under load for longer than is possible with known package testers working at an equivalent test rate.
