Abstract
A container inspection apparatus for inspecting coating integrity includes an electrical control system that produces an output signal representative of the reflectivity of an inner surface of the container which is fed to a microprocessor and is compared with lower and upper limit references. If the output signal is outside the limit references, an ejector mechanism located in a path for moving containers is activated to remove the defective container from the path. The ejector mechanism includes flipper rods pivoted at one end and located in an inclined portion of the path so that the defective containers are removed by gravity feed.
