How To Buy Bottled Water Equipments?
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 water 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 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.
U.S. public drinking water is regulated by the Environmental Protection Agency (EPA).
Bottled water line falls under the Federal Food and Drug Administration (FDA) as a food product. Consumer beliefs that bottled water is safer than tap water continue to fuel the billion-dollar-a-year bottled water industry. With several recalls between 2000 and 2009, and isolated instances of illness possibly from vending machine bottled water, the public is beginning to question current industry standards.
# The Natural Resources Defense Council (NRDC) conducted an extensive review of bottled water, tap water and a safety standards comparison. The study concluded that bottled water is not necessarily safer or cleaner. In fact, some bottled water, the NRDC stated, was simply tap water put into a bottle. The majority of bottled water ended up being safe, but quality was low in some brands, posing health risks to those with weakened immune systems.
A second problem is the plastic bottle itself. Research is being done on phthalates, a chemical known to upset hormone levels.
Bottled water equipment manufacturer stored for as little as 10 weeks, one study found, showed that phthalates had leached from the plastic into the water. For low-turnover vending machines, bottled water could stay unsold over a long period of time.
In accordance with the present invention, a water dispenser is provided which is effectively sealed from ambient pollutants and contaminants. The dispenser does not use a reservoir to seal the inverted water supply bottle. Air is allowed to directly enter the water bottle through an air filter. The water exits the water supply bottle directly into a closed water conduit equipped with a dispensing valve from which the water is dispensed. A check valve is provided to prevent air from entering the water supply bottle through the dispensing valve. Also, a check valve can be used to stop water from reaching the air filter and to stop the flow of water through the air filter if the bottle is cracked or has a pin hole leak that will allow air to enter the inverted water supply bottle.
Simply looking at bottled water cannot expose low quality or contamination. Only a few states in the United States enforce strict standards on
filling machines . According to the NRDC, a label saying, "from a community water system" or "from a municipal source" is mostly likely tap water. Until bottled water companies are further mandated to disclose information, there is no way of recognizing storage length or quality levels.
According to Joshua Sharfstein, Principal Deputy Commissioner of Food and Drugs at the FDA, which is part of the Department of Health and Human Services (HHS), the FDA regulates bottled water following specific codes. However, they have not adopted all EPA regulations that apply to public drinking water. Sharfstein states that an increased number of consumer calls to the FDA with questions about bottled water safety have led to a review of the FDA's mandates.
