ABSTRACT:
The integrity of the dividing partitions walls of a multichamber container can be tested for voids after the filling of the containers. This is particularly useful for multichamber tube containers. These containers can have relatively thin tube divider partitioning walls which can have voids in the partitioning, in the attachment of the partitioning to the container walls, or in the case of a tube container the attachment of the dividing partition wall to the shoulder. The container chambers are filled with the substances which also are electrolytes and at the time of filling or just subsequent to filling, a potential difference is applied to each of chambers. Since the substance in each chamber is an electrolyte the potential difference extends throughout each side of the barrier. If there are one or more voids in dividing partition, there will be decrease in the potential difference. This can be detected on a meter or the potential difference can operate a switch that directs containers that have been found to have voids to a reject chute.
