Multi composition stick product and a process and system for manufacturing the same

A system for simultaneously manufacturing a plurality of multi-composition stick products, for topical application, in a plurality of containers, each stick product including a stick composition comprising a first composition and a second composition, the first and second compositions differing by at least one component and being arranged in a predetermined non-random pattern that is reproducible, comprising:

• a support tray having a plurality of holes defined therein for receiving the plural containers;
• a holding member;
• and
• a plurality of interchangeable filling nozzles, each filling nozzle being secured to the holding member by an associated releaseable locking member, and each filling nozzle comprising:
• a heated mold shaft insertable into an associated container;
• an outer barrier disposed around at least a portion of the mold shaft, a passageway is formed by the inner surface of the outer barrier and the outer surface of the mold shaft for receiving the first composition into the container around the mold shaft.

A system for manufacturing a multi-composition stick product in a container having an inner contour and an outer contour, the stick product including a stick composition comprising a first composition and a second composition, the first and second compositions differing by at least one component and being arranged in a predetermined non-random pattern that is reproducible, comprising:

• a screw disposed inside the container;
• a filling nozzle comprising:
• a mold shaft insertable into the container and received the screw;
• an outer barrier disposed around at least a portion of the mold shaft, a passageway is formed by the inner surface of the outer barrier and the outer surface of the mold shaft for receiving the first composition into the container around the mold shaft.
