ABSTRACT:
A sanitizer dosing dispenser for immersion in a body of water such as a toilet tank whose water line can be lowered from an upper level to a lower level by flushing, which includes a product chamber for containing a solid, water soluble material, first and second walls defining a first flow path therebetween for providing a predetermined volume of water from the body of water to the product chamber along the first flow path in response to the level of the body of water falling from the upper level to the lower level. The first wall is flexible and located so that hydrostatic pressure from the body of water presses the first wall against the second wall to close the first flow path against water flow therealong when the level of the body of water is above the first wall, and permits the predetermined volume of water to flow into the product chamber to dissolve a portion of the soluble material therein when the level of the body of water is below the first wall. The dispenser also includes structure for dispensing substantially the same predetermined volume of solution from the product chamber along a second flow path into the body of water when the body of water falls from the upper level to the lower level. The dispenser includes a water chamber in fluid communication with the exterior of the dispenser for holding the predetermined volume of water above the first flow path when the body of water is at the upper level. When the first flow path opens, the predetermined volume of water falls therealong by gravity into the product chamber.
