A dispensing valve cap mountable to a bottle is provided with a first valve part having a tubular portion having an air inlet and a fluid outlet spaced apart along a longitudinal axis of the tubular portion to form a constant head valve for dispensing fluid from the bottle. A second valve part of the valve rotatably mounted to the first valve part includes a tubular portion for simultaneously closing both the air inlet and the fluid outlet of the first valve part when fluid dispensing is not desired. The second valve part further includes an air inlet, and a fluid outlet alignable with the air inlet and the fluid outlet of the tubular portion when fluid dispensing is desired. The dispensing valve cap controls fluid flow from the bottle. The bottle with the valve cap is useable with a dispenser assembly for mixing a concentrated fluid from the bottle with a dilutant. A tamper resistant lock prevents undesired rotation of the second valve part relative to the first valve part. The tamper resistant lock is deactivated upon insertion of the valve cap into the dispenser assembly. An orifice insert member with a predetermined fluid control aperture is positioned in the fluid outlet path to control fluid flow rate through the valve cap.

1. A dispensing valve cap for use with a bottle having an outlet and containing fluid for dispensing the fluid in a gravity feed fluid dispensing system, the valve cap comprising:a first valve part having a first end and a second end, the first end adapted to be fixedly mounted to the outlet of the bottle, the first valve part including a tubular sidewall portion defining a longitudinal axis extending in a direction from the first end to the second end, the tubular sidewall portion including an air inlet aperture through the tubular sidewall portion, the tubular portion further including a fluid outlet aperture through the tubular sidewall portion, the air inlet aperture spaced apart from the fluid outlet aperture along the longitudinal axis, the air inlet aperture adjacent to the first end, the fluid outlet aperture adjacent to the second end; and a second valve part rotatably mounted to the first valve part about the longitudinal axis, the second valve part including a mating portion adapted to cooperate with the tubular sidewall portion of the first valve part to close the air inlet and the fluid outlet apertures of the first valve part when the second valve part is in a first position relative to the first valve part, and to open the air inlet and the fluid outlet apertures of the first valve part when the second valve part is in a second position relative to the first valve part, the second valve part defining a fluid passageway for fluid to exit the valve cap at an exit opening location at a bottom of the valve cap, the fluid passageway extending in a direction parallel to the longitudinal axis of the first valve part at the exit opening which is disposed such that the fluid exits the fluid passageway in a direction parallel to the longitudinal axis.
