ABSTRACT:
An automatic bottom-of-the-tank toilet bowl cleaner device which dispenses a metered amount of cleaning solution into a toilet bowl after each flush. The device has a reservoir which contains concentrated cleaning solution. The reservoir has a vent which is ordinarily closed off by a flotation unit, thus preventing the cleaning solution from being released into the tank. When the toilet is flushed, the water level in the tank drops, thereby lowering the flotation unit, allowing air to enter the reservoir through the vent, and releasing a measured quantity of cleaning solution into the toilet tank.
