Dispensing apparatus for a toilet

The invention provides for a dispensing apparatus removably mounted to a toilet for dispensing a fluid into the toilet to control bathroom odor. The apparatus includes a housing having an open end and a bottom defining a cavity for receiving the fluid. The housing further defines an outlet for communicating the fluid to the toilet. A pump is mounted about the open end of the housing and defines a chamber above the cavity. The chamber is in fluid communication with the cavity and includes a plunger movable within the chamber between actuated and unactuated strokes. The plunger includes at least one aperture in fluid communication with the chamber. The aperture is blocked during the actuated stroke of the plunger for displacing the fluid. The aperture is open during the unactuated stroke of the plunger to equalize pressure within the chamber and the cavity with atmospheric pressure.
