Abstract: An aerosol system for dispensing liquid material, comprising a container assembly and an actuator assembly comprising an outlet member defining an outlet opening, a collar member, an actuator member, and a selector member. The actuator member supports the collar member and the outlet member such that movement of the collar member relative to the actuator member causes the collar member to deform the outlet member. Movement of the selector member relative to the collar member moves the collar member relative to the actuator member. Deformation of the outlet member alters a cross-sectional area of the outlet opening. When the actuator assembly is in a first position, the liquid material is prevented from flowing out of the container. When the actuator assembly is in a second position, the liquid material is allowed to flow out of the container assembly through the outlet opening.
