ABSTRACT:
A passive dosing dispenser for issuing, for example, a predetermined volume of a liquid toilet tank additive solution into a toilet tank as the water is draining therefrom while the toilet is flushing. A preferred dispenser comprises an internal reservoir having a product chamber for containing a quantity of a solid type product which can be dissolved in water to form a toilet tank additive product solution and a liquid solution reservoir for containing a quantity of said solution in fluid communication with said product chamber, and inlet/discharge conduit having its lowermost end in fluid communication with said liquid solution reservoir and its uppermost end in fluid communication with a syphon tube, and air trap disposed adjacent said inlet/discharge conduit for isolating said liquid product solution from the toilet tank water in said syphon tube during quiescent periods, and an air vent in fluid communication with said liquid solution reservoir and said product chamber. To accommodate solid type products which have a tendency to form a gel while dissolving, novel clog prevention, i.e., anti-clogging means are provided within the dispenser to limit the amount of non-gelled solid product exposed to liquid and to maximize the area of contact between the liquid contained within the dispenser and the gelled product. The novel anti-clogging means helps ensure that dispensing of a predetermined quantity of the liquid solution will occur with each flush cycle of the toilet.
