Abstract

An aerosol dispenser has a container with a deformable side wall and an internal chamber storing a propellant and a component to be sprayed through a discharge nozzle. A control valve mounted on the top of the container regulates the flow of fluid through the nozzle. A frangible ampule storing a second component is retained in the chamber adjacent a portion of the side wall. The ampule can be broken with a lever mounted on the outside of the container in alignment with the ampule. The lever is manually moved to deform the side wall and break the ampule so that the component in the ampule is mixed with the fluid in the chamber.
