  • Patent number: 8142654
    Abstract: A disposable and recyclable water bottle formed of a non-toxic plastic composition includes a flexible sidewall, a neck with an open top and cap, and an open bottom end. A filter cartridge is received within the open bottom and contains activated carbon sandwiched between 0.7 to 50 microns filtration membranes, all contained between upper and lower perforated plates. A lower portion of the filtration cartridge provides a filling chamber for receiving a flow of unfiltered water on to the lower perforated plates for passage through the filter. An arrangement of slots in the walls of the filling chamber allows a portion of the flowing water to bypass the filter in order to prevent overflow when filling the bottle. A cap containing internal screw threads attaches to the external screw threads of the open bottom end, sealing the interior of the bottle. Once sealed, the contained water is allowed to move around in a fluid motion between the interior of the bottle and the filling chamber.
