Abstract

Abstract Improved dispenser assembly for controlled release of bactericidal, detergent and aromatic agents upon flushing, which dispenser clips onto the upper edge of a toilet bowl. The assembly is specially adapted to bring a solid type deodorant/disinfectant cake into position along the side wall of the bowl but below the rim so that upon flushing, the flush water is directed to the cake in a turbulent action that releases limited amount of the cake. The dispenser disposes the cake above the bowl water line, and shields it from urine or splash so that it does not dissolve too rapidly.
