An apparatus and a process for filling a plural chamber container, such as a container, with plural flowable materials. The container might be a two-compartment dentifrice container or a two-compartment adhesive container, for example. The container has internal partitioning dividing it into plural chambers, and the partitioning must be properly positioned to permit supply nozzles to enter the respective chambers. In one embodiment, the partitioning is positioned by probes which are inserted into the chamber, following which relative rotation between the container and the probes causes the probes to position the partitioning. In a second embodiment, air nozzles emit air jets to position the partition. In another embodiment, an electrostatic charge is induced on the container sidewall and on the partition, and the like charges cause the sidewall and the partition to repel each other, positioning the partition. In a further embodiment, an air/vacuum nozzle is inserted into one of the container chambers, and air jets and suction are alternated to position the partition so that a supply nozzle can be inserted into each chamber of the container.

[ What is claimed is:] [8.] A process for filling two flowable materials into a container having a sidewall, a closed end, an open end and an internal flexible partition extending from the closed end to the open end to provide two chambers to maintain the two materials separated within the container

[ What is claimed is:] [8.] A process for filling two flowable materials into a container having a sidewall, a closed end, an open end and an internal flexible partition extending from the closed end to the open end to provide two chambers to maintain the two materials separated within the container, said flexible partitioning having a first and a second side edge, each side edge attached to said sidewall, said internal flexible partitioning having a transverse dimension greater than the linear distance of the first side edge attachment to said sidewall and said second side edge attachment to said sidewall, said process comprising the steps of:(a) positioning the container with a known orientation;(b) positioning the internal partition at a desired location within the container;(c) inserting a first supply nozzle into a first one of the two chambers and discharging a known quantity of the first material into said first one of the two chambers; and(d) inserting a second supply nozzle into the other one of the two chambers and discharging a known quantity of the second material into said other one of the two chambers.
