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.

A cap for use with water treatment apparatus wherein the cap is adapted to cooperate with an open neck of a bottle having an exterior projection formed on the neck thereof, and a tubular member inserted within the open neck, said cap comprising: 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 surface means for cooperatively engaging the tubular member mounted in the open neck of the bottle to seal the tubular member; and a top portion of said lower component having a central part, and a peripheral part which has a plurality of circumferentially spaced through-extending openings therein, said openings disposed substantially 360 degrees around the circumference of said peripheral part of said top portion; and an upper component having a depending stem which is constrained to axially slidable movement in a bore formed in said central part between a closed position wherein said upper component covers said openings, and an open position wherein said upper component is axially spaced from said lower component around the periphery thereof so that liquid may freely flow through the openings in said lower component top portion when said surface means is not in engagement with said tubular member, and then between the upper component and the lower component under the force of gravity.
