  • Patent number: 5507329
    Abstract: In general, distilled water dispensers used in commercial establishments such as drug and convenience stores are unimaginative, coin operated and often messy devices. A relatively simple substitute for such dispensers includes a large housing similar in size and shape to a soft drink dispenser, a smaller housing in the large housing with essentially only the door of the inner housing extending out of the center of the larger housing. A one, three or five gallon bottle is placed in the inner housing and the door is closed. These two actions close two switches which cause a dispensing head to descend from a rest position into the open mouth of the bottle. Movement of the dispensing head to the dispensing position closes a third switch, which causes a solenoid valve to open permitting the flow of distilled water to the bottle.
