Patent ID: 7073965

Claim:
A system for manufacturing a plurality of multi-composition stick products 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 plurality of support trays, each support tray having a plurality of holes defined therein for receiving the plural containers; a conveyor belt for receiving the support trays and moving the support trays from a first end of the conveyor belt to a second end of the conveyor belt past a plurality of stations; a first one of said stations comprising: a filling nozzle having a predetermined number of ejection heads for filling the containers with the first composition in a liquid state; a second one of said stations comprising: a mold shaft insertable into an associated container while said first composition is in the liquid state; a third one of said stations comprising: a device for removing the mold shaft from the associated container after the first composition has begun to solidify, thereby forming a cavity complementary in shape to that of the respective mold shaft in the first composition in each associated container; a fourth one of said stations comprising: a second filling nozzle having a predetermined number of ejection heads for filling the cavities with the second composition in a liquid state; and a first plate disposed adjacent to the second filling nozzle and above the conveyor belt to ensure that the second composition fills the cavities and reduces the amount of excess second composition.
