ABSTRACT:
A container of the chemical to be dispensed is supported in inverted position in the toilet flush tank with the mouth of the container opening downwardly. The dispensing closure is sealingly associated with and axially adjustable on the container around its mouth. The closure has an open lower end normally immersed in the water within the tank and separated by a partition from the metering chamber within the upper end of the closure communicating with the container mouth. The liquid is delivered by gravity into the metering chamber, to a depth to cover said mouth. Pressurized air delivered from the pump chamber into the upper portion of the metering chamber above the mouth exerts a pressure on the liquid within the metering chamber to force the same out through a discharge port and tube leading to the tank overflow pipe.
