Abstract
Abstract Novel apparatus is disclosed for deodorizing and cleansing a toilet bowl in which a fragranced detergent cake is floated on the surface of the water in the hold tank with a small volume of water on the detergent. The container holding the detergent is adapted to drop with the water as the water is exhausted during flushing and to spill the perfumed detergent containing water into the final increment of flush water leaving the tank. This water then remains in the toilet bowl after flushing.
