US 4,695,379 A · Water treatment apparatus

Abstract

Contaminants in normal drinking water may be easily and effectively reduced. An elongated tube has first and second ends and is connected with an interference fit at its first end to the interior surface of a neck of a conventional bottle. Water treatment media is disposed within the tube adjacent its second end, such as activated charcoal, silver impregnated media, ion exchange resins, or calcium and/or magnesium leaching material. The tube includes a flange adjacent its first end which minimizes the possibility that water will enter the bottle except by flowing through the open first end of the tube. A cap is provided for disposition over the tube, the cap sealing the open first end of the tube to prevent water from flowing through it, and the cap apertured substantially 360 degrees around its circumference to allow free flow of water from the bottle which has already been treated by the treatment media.
