A filter assembly consists of four principal components. The principle components include a top housing containing the means to fasten in a leak proof manner to a valved top of a sport bottle; a base housing; an outer independent charged layered membrane filter; and an inner independent charged layered membrane filter. Each charged layered filter is in a cylindrical form with pleats.

Enhanced biological filters for sport bottles

A monolithic carbon composite filter for use in water filter bottles of the type having a bottle cap and a valved vented top. The filter is formed with exposed surfaces including side walls and a base. The filter employs both radial flow through the side walls of the filter and axial flow through the filter base. All available exposed surfaces thus maximize the available surface area for filtering water. As a result a larger diameter filter suited to the addition of a second media as well as an inner tube providing for separate axial flow may be utilized. A dual aspect or universal flow filter adapted to be attached to a filter housing top is capable of being cooperatively attached to the bottle cap and bottle with a valved vented top. The bottle is normally inverted for drinking.

Portable universal flow filter

A media in the form of a multilayered semi porous composite membrane containing a strong positive electrical charge with a highly porous surface consisting of 60 to 90 percent void volume and pore size of about 2 micron capable of retaining negatively charged protozoa, bacteria, and virus as well as di-pole particulate matter as a result of the attraction of the positive charge. A housing is a portable adaptive housing containing and supporting the composite membrane. A low pressure stream of water is within the housing and passes through the media. A composite membrane is positioned within the adaptive housing in the path of the low pressure stream of water. The composite membrane is adapted to treat the low pressure stream of water under from 0.3 to 10 psig pressure delivering 5 to 30 ml/sec.

Water treatment system

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.

Water treatment apparatus

A detent and numerical indicia are associated with a cap for a water treatment apparatus to keep track of how many times a bottle in which the treatment apparatus is disposed has been filled and emptied, to provide for periodic replacement of the filter media. The treatment apparatus is for attachment to a bottle with an opening at a neck portion, and includes an elongated tube, a cartridge containing water treatment media connected to one end of the tube, and a cap for capping the other end of the tube. The cap includes a body having through-extending passages therein, and a top which is movable with respect to the body to selectively cover or uncover the passageways. A detent is associated with the cap body and the top for providing detented rotation of the top with respect to the body. Indicia are associated with the cap top and the cap body for indicating each detented position. Thirty-one Arabic numbered positions and another blank position may be provided as the indicia, cooperating with an arrow that is stationary. Each time the bottle is filled the cap top is rotated one position with respect to the body, and once the last indicia is indicated on the top, the filter is replaced. An adaptor connects the tube to the filter cartridge, and the adaptor can also include water treatment media.

Bottled water cap with indicator and adaptor

A cap for use with water treatment apparatus specifically adapted to cooperate with an open neck of a bottle having an exterior projection formed on the neck thereof. The cap includes a lower component having a circumferentially continuous lower portion which has an interior projection adapted to cooperate with the exterior projection of the bottle, and surfaces for cooperatively engaging a tubular member mounted in the open neck of the bottle. The cap lower portion also includes a top portion having a central part and a peripheral part which has a plurality of circumferentially spaced through-extending openings, the openings disposed substantially 360 degrees around the circumference of the cap. The upper component of the cap is mounted for axially slidable movement relative to the lower component from a closed position wherein the upper component covers the openings, to an open position wherein the upper component is axially spaced from the lower component around the periphery thereof so that liquid may freely flow through the openings in the lower component top part, and then between the upper component and the lower component under the force of gravity.

Cap for use with water treatment apparatus

A water treatment system and related components for reducing contaminants in normal drinking water are provided. An enlongated 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, 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 wuen an upper portion of said cap is moved axially relative to the lower portion from a closed to an open position. 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.

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.
