According to a study led by the Water Research Foundation
A sealed bottled water equipment 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.
According to a study led by the Water Research Foundation, many people perceive bottled water as healthier than tap water. The study showed that consumer dissatisfaction with tap water leads to increased consumption of alternatives such as filling machines . A strong marketing push by bottled water companies added to this limited consumer satisfaction equals increased bottled water sales. The ubiquitous plastic bottles are now sold alongside other beverages in vending machines worldwide.
Bottled water dispensers are frequently used in manufacturing plants and chemical factories to provide a supply of water convenient to the area where the employees are working. In many work areas, the air is contaminated with dust from the materials being worked upon. In chemical plants, the air is often contaminated by solvents and dust from solid materials being used in chemical processes and from finished product. The bottled water dispenser stands surrounded by this environment. When an employee takes a drink from the bottled filling machine , the water pours from a reservoir into the cup or container held in the hand of the employee. As we are all familiar, air must enter the water supply bottle to relieve the partial vacuum in order for the water to empty from the bottle. The air frequently bubbles in an erupting stream of large and small bubbles which carry with them all of the contaminants in the ambient air surrounding a water cooler. As successive employees draw water from the dispenser, the air continues to bubble into the supply bottle, further contaminating the water as well as the water in the reservoir in the water dispenser. In order to avoid this health hazard, it would be desirable if the water in the water supply bottle could be protected from contamination as it empties and is displaced by the necessary air. Also, it would be convenient if this could be done using conventional water bottles which are not modified in any way.
Also, conventional water dispensers include a reservoir of water filling machines for sealing the bottle and for limiting air flow into the bottle. When the water drops below the end of the neck of the inverted water bottle, air can enter the bottle to relieve the partial vacuum and allow water to exit the bottle, and rise again in the reservoir, to again close off the air passage. This reservoir can also trap ambient contaminants presenting a serious health hazard.
