Abstract

A chemical dispenser ( 100 ) for use with a flush toilet includes a chemical storage chamber ( 101 ) for a chemical which is to be added to the flushing water of the toilet, a mounting apparatus that allows the chemical dispenser to be easily mounted on an existing opening in the water storage tank ( 120 ) of the toilet, and a dispensing mechanism ( 150 ) that dispenses a predetermined quantity of the chemical into the flushing water of the toilet each time the toilet is flushed.

1 . For use with a flush toilet, a chemical dispenser including: 
 a chemical storage chamber for a chemical which is desired to be added to the flushing water of the toilet;    mounting apparatus fabricated to allow said chemical dispenser to be readily mountable on an existing opening in the water storage tank of the toilet; and    a dispensing mechanism operative to dispense a predetermined quantity of the chemical into the flushing water of the toilet each time the toilet is flushed.    
   
   
       2 . A dispenser according to  claim 1 , wherein said dispensing mechanism includes a float located in the water storage tank of the toilet operative to drive said dispensing mechanism as it rises and falls with the water level in the water storage tank of the toilet.  
   
   
       3 . A dispenser according to  claim 1 , wherein said dispensing mechanism is driven by the pressure of water flowing into the water storage tank of the toilet.  
   
   
       4 . A dispenser according to  claim 1 , wherein said dispensing mechanism includes apparatus for producing an increase in pressure within said dispensing mechanism in response to the refilling of the water storage tank of the toilet after flushing, and for dispensing a predetermined quantity of the chemical into the flushing water of the toilet each time the toilet is flushed.
