Description
Title of the invention: STICK PRODUCT REFILL SYSTEM
[0001] BACKGROUND OF THE INVENTION
[0002] The present invention relates to the general field of stick products and their dispensers, and more particularly to stick product refills.
[0003] Stick products, such as lipsticks and deodorants, are generally used in dispensers with a push-pull mechanism, in which a threaded spindle is rotated to advance and retract longitudinally a receptacle containing the stick product. In existing dispenser systems, when the stick product is depleted, at most the outer casing of the dispenser can be reused, but the push-pull mechanism is discarded. The present invention provides a system by which the stick product can be refilled without discarding the dispenser's push-pull mechanism, thereby advancing recycling and resource conservation goals, while also enabling savings for consumers.
