Abstract
A spray cap, also known as an actuator overcap for an aerosol container, has an acoustic seal between the actuator button and the overcap. This acoustic seal is formed by a set of matching sealing lips on the actuator button and also on the overcap, such that they are both oriented horizontally. At rest, the sealing lip of the actuator button rests above the sealing lip of the overcap, but during actuation, the sealing lip of the actuator button deforms the sealing lip of the overcap, which both forms an acoustic seal during actuation and creates the force to return the sealing lip of the actuator button back to its original position after actuation is complete.
