ABSTRACT:
Apparatus and an associated method for inspecting a container neck for the desired shape includes an upper body portion having an elongated bore therethrough, and a downwardly projecting lower body portion having a passageway generally aligned with the bore. The lower body portion has an outer surface corresponding to the desired shape of the inner portion of the container neck but of a size corresponding to the minimum permissible inside diameter of the container neck. In one embodiment the lower body portion has at least one vent opening to facilitate improved container neck inspection. Sealing material is provided such that when the container neck is of the desired shape the lower body portion will be received within the neck in such a manner that the passageway will be in sealed communication with the container interior.
