Abstract
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.
