Abstract:
1. A dispenser for containing and dispensing a measured quantity of a freely flowing material, said dispenser comprising: a first segment having a disc with an upper surface and a lower surface, a shaft having a first end which is fixedly attached at the center of the lower surface of the disc and a second end, and two apertures opposingly disposed in the disc; a second segment substantially in the form of a barrel and having an upper surface, a lower surface, a central bore and two axial chambers situated on either side of the bore and extending through the barrel; a third segment having a cylindrical wall with an inner surface and an outer surface, a cover member integral with the upper edge of the wall and having an upper surface and a lower surface and two apertures opposingly disposed in the cover member; and means to permanently affix the second end of the shaft to the center of the upper surface of the cover member; whereby when the second end of the shaft is passed through the central bore and the disc is rotated until an imaginary line through the apertures in the disc is at 90° to an imaginary line through the apertures in the cover member and the second end of the shaft is permanently affixed to the upper surface of the cover member, the lower surface of the disc is substantially contiguous with the upper surface of the barrel and the lower surface of the barrel is substantially contiguous with the upper surface of the cover member, the first segment and the third segment can function as a single unit, and when the barrel is rotated with respect to the unit so that the apertures in the cover member communicate with the bottoms of the chambers and the disc closes the tops of the chambers the dispenser can be filled with the freely flowing material and when the barrel is rotated with respect to the unit so that the apertures in the disc communicate with the tops of the chambers and the cover member closes the bottoms of the chambers the dispenser can dispense the freely flowing material.
