ABSTRACT:
A water bottle sanitation shield covers the neck and shoulder regions of the bottle and effectively insulates the interior of the cooler tank from contaminants that may have accumulated on the bottle during transport and handling. The shield comprises film of non porous material that is secured around the mouth of the bottle by an annular retention cap. The film has a perforated region for placement over the mouth of the bottle and a pull cord attached to the perforated region. The film is sized so that, when the bottle is inverted and lowered onto the tank opening, the film extends beyond its edge, thereby effectively closing off the tank opening. To remove the perforated region, the bottle is tilted at its shoulder region, to provide free movement for the pull cord. Pulling the cord causes the perforated region of the film to tear away, thereby allowing the water within the bottle to pass through the mouth of the bottle and into the water cooler tank. Since the shield is now in place between the bottle and the interior of the tank, being firmly captured by the retention cap and by the pressure of the shoulder region of the bottle against the perimeter of the tank opening, the interior of the tank is completely shielded from the intrusion of contamination that may be present on the external surface of the bottle.
