ABSTRACT:
A manually operated continuous aerosol sprayer which eliminates the need for the use of potentially environmentally dangerous substances. A container is provided to hold a liquid and an inflatable bladder is located inside the liquid container. A pump is provided for filling the bladder with air from the outside atmosphere. The open end of the inflatable bladder is attached to the pump so that it may be readily filled by the pump with the remainder of the inflatable bladder extending into the liquid container. When the bladder is inflated it expands causing the liquid in the container to become pressurized. The pressure from the inflation of the bladder causes the air and the liquid to be forced into a spray chamber where they mix and are forced out a spray nozle as an aerosol spray.
