ABSTRACT:
Toilet disinfectant liquid is dispensed from an inverted container suspended within a toilet tank. As the toilet tank is refilled at the conclusion of a flush cycle, an inverted cup entraps air which then enters the container through a narrow elongated passage which prevents tank water from entering the container. When the water level in the tank falls during the succeeding flush cycle, disinfectant liquid passes through the narrow elongated passage and into the toilet tank. Bubbles formed in the elongated passage prevent continued dispensation of the disinfectant.
