Abstract

A water treatment system and related components for reducing contaminants in normal drinking water are provided. 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, halogenated resins, ion exchange resins, 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, a lower portion of the cap sealing the open first end of the tube to prevent water from flowing through it, and 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 when an upper portion of said cap is moved axially relative to the lower portion from a closed to an open position. A replaceable filter cartridge is also provided for attachment to the lower end of the tube, the cartridge containing any one or more of filter media, flavoring concentrates and/or minerals or vitamin supplements. An adaptor is also provided for converting a snap-on cap bottle neck to a screw-on cap bottle neck so that a screw-on type cap may be utilized with either type bottle neck.
