ABSTRACT:
A container inspection apparatus inspects sealing performance of a closure of a container such as a bottle filled with effervescent beverage. The apparatus include a plurality of support members for placing a container thereon and movable along a certain path, a plurality of ultrasonic transducers fixed to one of the support members for generating ultrasonic vibration, and a supply device for supplying liquid to an upper surface of the support member. The ultrasonic vibration of the support member caused by the ultrasonic transducer is transmitted to a bottom of the container through liquid interposed between the bottom of the container and the upper surface of the support member. After vibrating the bottom of the container, beverage in the container is imaged by an imaging unit to detect a defective container which is not sealed properly.
