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.
Claims6
A liquid product dispenser for use in a conventional flush tank and automatically operable by rise and fall of water within said tank between predetermined minimum and maximum levels, comprising in combination:
- a liquid container having a generally cylindrical neck terminating in a discharge spout defining the mouth of said container;
- means for supporting the container in inverted position in a flush tank;
- a dispensing closure for said container comprising an open ended sleeve having an upper end sealingly associated with and axially adjustable on said container neck and a lower end adapted to extend into said water in the tank;
- a partition within said sleeve between its ends dividing same into an enclosed metering chamber between said partition and said container and a downwardly opening pump chamber for communication through its lower end with the water in said tank;
- a flow control cup carried by said sleeve within the metering chamber for axial movement with said sleeve into and from sealing engagement with said spout;
- said metering chamber communicating with said pump chamber through a pressure equalizing passage which communicates with the metering chamber at a first level above said cup;
- there being a discharge conduit communicating with said metering chamber at a second level below said first level and at a location outside of said cup.
