ABSTRACT:
An apparatus and method for testing a container as to leakage and defects. The apparatus is especially useful for testing plastic bottles because it does not contact one or more of the bottle sides during testing. A frame with the test components may be adjusted so that the apparatus will fit many different conveyor configurations and container sizes. A container is moved along by a conveyor, where it is sensed by a photo-eye to initiate testing. The test probe makes contact with the container opening, and travels with the container during testing. The test probe introduces air into the container and detects the maximum pressure and pressure decay. If the pressures are not within an acceptable range, the container is ejected from the conveyor.
