Actuator systems and methods for aerosol wall texturing

1. A system for dispensing texture material onto a target surface in a desired pattern that substantially matches an existing pattern on the target surface, comprising:

a container that stores texture material and propellant material;

an outlet assembly supported by the container, where the outlet assembly comprises

an actuator member having a stem portion and a plurality of fingers,

an outlet member arranged within the plurality of fingers, where the outlet member is deformable and defines an outlet opening, and

a roller member supported by the actuator member for movement relative to the actuator member such that movement of the roller member relative to the actuator member causes the roller member to act on the outlet member to alter a cross-sectional area of the outlet opening; and

an aerosol valve assembly arranged to allow control of fluid flowing out of the container; whereby

the outlet assembly is configured such that the cross-sectional area of the outlet opening corresponds to the desired pattern;

the aerosol valve assembly is operated to allow the propellant material to force the texture material out of the container through the outlet opening defined by the outlet assembly; and

the texture material forced out of the container is deposited on the target surface in the desired pattern.

2. A dispensing system as recited in claim 1 , in which the propellant material is a pressurized fluid.

3. A dispensing system as recited in claim 1 , in which the propellant material is at least one pressurized fluid selected from the group consisting of air and nitrogen.

4. A dispensing system as recited in claim 1 , in which the propellant material is inert.

5. A dispensing system as recited in claim 1 , in which the propellant material is hydrocarbon material that exists within the container in a liquid state and in a gas state.

6. A dispensing system as recited in claim 1 , in which, as the roller member moves relative to the actuator member, the roller member moves towards and away from at least one of the finger members such that the outlet member is deformed between the roller member and the at least one of the finger members.

7. A dispensing system as recited in claim 1 , in which, as the roller member moves relative to the actuator member, the roller member moves towards and away from the finger members such that the outlet member is deformed between the roller member and the finger members.

8. A dispensing system as recited in claim 1 , in which:

the actuator member defines at least one roller slot, where the at least one roller slot is angled with respect to a longitudinal axis of the outlet member; and

the roller member engages the at least one roller slot such that movement of the roller member along the at least one roller slot cause movement of the roller member towards and away from the outlet member.

9. A dispensing system as recited in claim 8 , in which the at least one roller slot defines a plurality of stop notches, where the roller member engages stop notches to secure the roller member in a desired position relative to the outlet member.

10. A dispensing system as recited in claim 1 , in which:

the actuator member defines first and second roller slot, where the at least one roller slot is angled with respect to a longitudinal axis of the outlet member; and

the roller member engages the at least one roller slot such that movement of the roller member along the at least one roller slot cause movement of the roller member towards and away from the outlet member.

11. A dispensing system as recited in claim 10 , in which the first and second roller slots each defines a plurality of stop notches, where the roller member engages stop notches to secure the roller member in a desired position relative to the outlet member.

12. A method for dispensing texture material onto a target surface in a desired pattern that substantially matches an existing pattern on the target surface, comprising:

storing texture material and propellant material in a container;

providing an actuator member having a stem portion and a plurality of fingers,

forming an outlet assembly by

arranging an outlet member arranged within the plurality of fingers, where the outlet member is deformable and defines an outlet opening, and

supporting a roller member relative to the actuator member for movement relative to the actuator member such that movement of the roller member relative to the actuator member causes the roller member to act on the outlet member to alter a cross-sectional area of the outlet opening; and

supporting the outlet assembly relative to the container;

arranging an aerosol valve assembly to allow control of fluid flowing out of the container;

configuring the outlet assembly such that the cross-sectional area of the outlet opening corresponds to the desired pattern;

operating the aerosol valve assembly to allow the propellant material to force the texture material out of the container through the outlet opening defined by the outlet assembly such that the texture material forced out of the container is deposited on the target surface in the desired pattern.

13. A method as recited in claim 12 , in which, as the roller member moves relative to the actuator member, the roller member moves towards and away from at least one of the finger members such that the outlet member is deformed between the roller member and the at least one of the finger members.

14. A method as recited in claim 12 , in which, as the roller member moves relative to the actuator member, the roller member moves towards and away from the finger members such that the outlet member is deformed between the roller member and the finger members.

15. A method as recited in claim 12 , in which:

the actuator member defines at least one roller slot, where the at least one roller slot is angled with respect to a longitudinal axis of the outlet member; and

the roller member engages the at least one roller slot such that movement of the roller member along the at least one roller slot cause movement of the roller member towards and away from the outlet member.

16. A method as recited in claim 15 , in which the at least one roller slot defines a plurality of stop notches, where the roller member engages stop notches to secure the roller member in a desired position relative to the outlet member.

17. A method as recited in claim 12 , in which:

the actuator member defines first and second roller slot, where the at least one roller slot is angled with respect to a longitudinal axis of the outlet member; and

the roller member engages the at least one roller slot such that movement of the roller member along the at least one roller slot cause movement of the roller member towards and away from the outlet member.

18. A method as recited in claim 17 , in which the first and second roller slots each defines a plurality of stop notches, where the roller member engages stop notches to secure the roller member in a desired position relative to the outlet member.
