Systems and methods for applying texture material to ceiling surfaces

A method of dispensing sprayable material in a desired spray pattern, comprising the steps of:

• providing an aerosol container defining an aerosol chamber adapted to contain sprayable material, where the aerosol container defines a container axis;
• mounting a valve assembly on the aerosol container to form an aerosol assembly, where
• the valve assembly is normally in a closed configuration in which the sprayable material is substantially prevented from flowing out of the aerosol assembly through the valve assembly, and
• when the valve assembly is arranged in an open configuration, the sprayable material is allowed to flow out of the aerosol assembly through the valve assembly;
• arranging the sprayable material and propellant material within the aerosol assembly;
• providing an actuator member defining an actuator passageway having an upper portion;
• supporting the actuator member on the valve assembly such that displacement of the actuator member towards the valve assembly along the container axis displaces the valve assembly from the closed configuration to the open configuration;
• providing a movable member;
• supporting the movable member on the actuator member;
• providing an outlet member defining an outlet passageway and a dispensing axis;
• supporting the outlet member at least partly within the upper portion of the actuator passageway such that the dispensing axis of the outlet member is substantially aligned with the container axis;
• arranging the movable member such that movement of the movable member relative to the actuator member deforms the outlet member to alter a cross-sectional area of the outlet passageway of the outlet member;
• and
• displacing the actuator member along the container axis towards the valve assembly to place the valve assembly in the open configuration to allow the propellant to force the sprayable material out of the container assembly along the dispensing axis.

An aerosol dispensing system for dispensing sprayable material in a desired spray pattern, comprising:

• an aerosol assembly comprising
• an aerosol container defining an aerosol chamber adapted to contain the sprayable material and a propellant material, where the aerosol container defines a container axis;
• a valve assembly mounted on the aerosol container, where
• the valve assembly is normally in a closed configuration in which the sprayable material is substantially prevented from flowing out of the aerosol assembly through the valve assembly,
• when the valve assembly is arranged in an open configuration, the sprayable material is allowed to flow out of the aerosol assembly through the valve assembly, and
• an actuator member defining an actuator passageway having an upper portion, and
• a plurality of outlet members each defining an outlet passageway and a dispensing axis;
• whereby
• the actuator member is supported on the valve assembly such that displacement of the actuator member towards the valve assembly along the container axis displaces the valve assembly from the closed configuration to the open configuration;
• a selected one of the plurality of outlet members is supported at least partly within the upper portion of the actuator passageway such that the dispensing axis of the selected outlet member is substantially aligned with the container axis;
• and
• displacement of the actuator member along the container axis towards the valve assembly places the valve assembly in the open configuration to allow the propellant to force the sprayable material out of the container assembly through the dispensing passageway of the selected outlet member.
