    Abstract: The sprayer of this invention is a crossbreed that combines the benefits of a pressurized air sprayer with the convenience a common bottle-top trigger sprayer. However, activating the trigger now has a reverse action causing the related pump to ingest air and the pump's traditional flow direction is now reversed. Air is passed into a reinforced reservoir bottle, near the top, similar to a pressurized air sprayer. Multiple hand-trigger-pulls are used to pre-pressurize air into the reservoir's chamber. A second conduit starting within and near the bottom of the reservoir utilizes air pressure to transfer product within the reservoir to a dispensing-valve. A means is provided to operate the dispensing-valve, which is able to dispense product continuously in-between compression strokes.
