Abstract

A simplified liquid dispenser comprises a hopper formed at the bottom into a base through which a base passage is drilled. The hopper contains the liquid to be dispensed. A rotary plug valve controls the flow of the liquid through the base. The plug valve is formed by a shaft journal which mates with a base bore which intersects the base passage at right angles. The shaft journal contains a shaft passage which, when aligned with the base passage, allows the liquid to flow out of the dispenser, and when not aligned with the base passage, prevents the exit of the liquid. A shaft handle contains a slot through which a restraining screw is attached to the base, allowing the rotation of the shaft through ninety degrees. The dispenser is fabricated from a hard, slippery plastic material, obviating the need for bearings.
