Abstract
A water treatment system including a bottle with a neck, a tube for disposition within the bottle and having water treatment material (such as activated carbon for removing a significant portion of the chlorine in tap water) associated with it, and a cap. The bottle is filled by causing water to flow through the tube, through the water treatment material, into the bottle. When filled, the bottle neck is closed off by screwing the cap into contact with the neck, the cap closing off the tube so that water does not flow through the tube out of the bottle, but rather exteriorly of the tube through openings in a cap first element and between the tube and the neck. A second element of the cap releasably closes off the water flow openings. In order to prevent leakage of water from the bottle even when tilted or dropped, the cap second element may be twisted with respect to the first element to lock the elements together in the closed position, and this—combined with the substantially elastomeric material sealing ring between the cap first element and the bottle—substantially prevents water from flowing out of the neck of the bottle. The water treatment material may easily be changed by removing a canister from an end of the tube and inserting a new canister into contact with the tube.
