Abstract
An elevator/threaded shaft dispensing package for a solid stick-form product. The package has a refill cartridge designed to telescope into a reusable base. The base is tubular and has a threaded shaft axially oriented within it through a central aperture at its bottom where the shaft is connected to a hand wheel. The cartridge holds the product in a tubular body which preferably has a non-circular cross-section. A push plate is disposed in the bottom of the cartridge and the top of the cartridge preferably has a downwardly extending annular collar on its exterior. The package has a telescoping elevator system disposed within it which includes a platform which abuts against the push plate and an internally threaded neck below the platform. The internally threaded neck receives the threaded shaft in threaded telescoping relation. When the hand wheel is turned in a predetermined direction the elevator system advances towards the top, pushing the product in the cartridge up and out of the package so the consumer can have access. The package is able to reset the elevator to its lowermost position when it is in its uppermost position without manually rotating the hand wheels.
