ABSTRACT:
A first vertical hollow cylinder is secured at an open lower end to the open end of the container. The first cylinder having a closed upper end with a small centrally disposed first opening therein and has a raised peripheral first lip. A curved vertical wall is secured to and extends upwardly from this upper end of the first cylinder. The wall engaging the first lip at two spaced apart positions and curves around one side of the first opening. A second vertical hollow cylinder open at both ends and secured to the upper end of the first cylinder so that its axial bore is vertically aligned with the first opening. A horizontally elongated member defines a figure 8 with left hand and right hand like half sections, each half section having a hole therein. One hole is sealed, the other hole being open. The member rests slidably on top of the second cylinder, with one member side slidably engaging the wall. A third vertical hollow cylinder has a second central opening aligned with the bore of the second cylinder and rotatably engages the first lip. First and second spaced vertical prongs extend downwardly from the third cylinder surface. Rotation of the third cylinder in one direction with respect to the first cylinder causing the first prong to engage the member, the member moving into a first position at which the sealed hole seals off the top end of the second cylinder. The third cylinder when rotated in the opposite direction causes the second prong to engage the member, the member moving into a second position at which the open hole is aligned with the open bore.
