Abstract: A vertical hollow container has a top opening. First and second vertically spaced horizontal plates are disposed in sealing engagement in the container opening. The plates have aligned central holes. A vertical hollow pouring shaft is secured at its bottom open end to the aligned holes and extends upwards from the upper plate. First and second overlapping horizontal rotatable discs are disposed between the plates. Each disc is separately and individually rotatable about a corresponding axis. The discs each have off center holes which can be individually aligned with each other and with the aligned holes in the plates.
