ABSTRACT:
A dispensing device adapted to be disposed within a toilet tank for sanitizing the tank and the bowl. The dispensing device includes a substantially closed receptacle containing therein a suitable dry chemical, such as calcium hypochloride, which mixes with water to form a saturated solution within the receptacle. A standpipe of selected diameter and length extends through the top wall of the receptacle to permit communication between the interior of the receptacle and the interior of the tank. During flushing of the tank, the turbulence of the flow within the tank causes a metered amount of saturated solution to be withdrawn from the dispensing device and mixed with the tank water. By using a standpipe having a preselected diameter and length, optimum and uniform diffusing of the chemical solution through the standpipe is achieved.
