Abstract
A sealed bottled water dispenser for using an inverted water supply bottle which has a sealing cap which, when pierced, causes water to flow into a sealed water conduit. A source of filtered air is connected to said water conduit to supply cleaned air to said water supply bottle. A check valve is placed in the water conduit to prevent unfiltered air from entering the water supply bottle through the water conduit. A check valve can be used in the water conduit to prevent water from reaching the air filter after the water supply bottle is delivering water. The latter check valve also prevents water from exiting the water bottle through the air filter, if an air leak is present in the water supply bottle. A cover is provided for sealing the water dispenser when a water bottle is not in place. The insertion of an inverted water bottle into the dispenser causes said cover to open to allow water to flow directly from the water supply bottle into the water conduit without flowing into a reservoir. A valve controls the delivery of water from the dispenser and seals the water in the dispenser from contamination.
