Abstract
A cleaning dispenser assembly to be used in connection with a toilet tank is coupled to a fill valve and an overflow tube of the tank. The dispenser assembly includes a container with a removable lid. A refill tube is coupled to a fill valve of the tank and the container. Tall and short discharge tubes are coupled to the container at different heights to facilitate the withdrawal of fluid from the container while preventing a vacuum from developing within the closed container. U-traps are formed in the refill tube and the discharge tubes to retain a portion of liquid in a steady state so as to seal the passageways in order to prevent gases from escaping into the tank.
