  • Method and apparatus for statistically testing frangible containers
    Patent number: 4109511
    Abstract: Method and apparatus for statistically testing frangible containers produced by plural mold sources by selectively diverting containers to a test station at regular intervals of time. A diverted container is automatically tracked to the test station wherein it is tested. A signal indicative of the result of the test is generated for use in selectively diverting additional containers produced by the same mold source that produced the tested container. The totality of containers produced by the plural mold sources is upgraded by automatically ejecting all containers produced by one or more mold sources for fixed periods of time as a function of the test results.
