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

an outlet assembly, where the outlet assembly comprises an actuator member,

a plurality of outlet members supported by the actuator member, where the plurality of outlet members are spaced around and define an outlet opening, and

an adjustment member supported by the actuator member such that movement of the adjustment member relative to the actuator member causes the adjustment member to act on the plurality of outlet members to alter an amount of overlap between the outlet members and thereby alter a cross-sectional area of the outlet opening; 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 allows 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:

the actuator member defines a first threaded portion; and

the adjustment member defines a second threaded portion; whereby

the first threaded portion engages the second threaded portion such that rotation of the adjustment member relative to the actuator member causes the adjustment member to act on the plurality of outlet members to alter the cross-sectional area of the outlet opening.

7. 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 the steps of:

storing texture material and propellant material in a container;

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

providing an outlet assembly comprising

an actuator member,

a plurality of outlet members supported by the actuator member, where each of the plurality of outlet members overlaps an adjacent outlet member to define an outlet opening, and

an adjustment member supported by the actuator member such that movement of the adjustment member relative to the actuator member causes the adjustment member to act on the plurality of outlet members;

moving the adjustment member relative to the actuator member such that the adjustment member acts on the plurality of outlet members to alter an amount of overlap between the outlet members and thereby alter the cross-sectional area of the outlet opening 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 is deposited on the target surface in the desired pattern.

8. A method as recited in claim 7 , in which:

the actuator member defines a first threaded portion; and

the adjustment member defines a second threaded portion; whereby

the first threaded portion engages the second threaded portion such that rotation of the adjustment member relative to the actuator member causes the adjustment member to act on the plurality of outlet members to alter the cross-sectional area of the outlet opening.

9. A method as recited in claim 7 , further comprising the steps of:

forming a first threaded portion on the actuator member;

forming a second threaded portion on the adjustment member;

engaging the first threaded portion with the second threaded portion; and

rotating the adjustment member relative to the actuator member to cause the adjustment member to act on the outlet member to alter the cross sectional area of the outlet opening.

10. A method as recited in claim 7 , further comprising the step of forming an engaging portion on the adjustment member, where the engaging portion is sized and dimensioned to deform the at least one outlet member when the adjustment member moves relative to the actuator member.

11. 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 aerosol valve assembly arranged to allow control of fluid flowing out of the container; and

an outlet assembly, where the outlet assembly comprises

an actuator member,

an outlet member supported by the actuator member, where the outlet member is rolled such that edges of the outlet member overlap to define an outlet opening

an adjustment member supported by the actuator member such that movement of the adjustment member relative to the actuator member causes the adjustment member to act on the at least one outlet member to alter an amount of overlap between the edges of the outlet member and thereby alter a cross-sectional area of the outlet opening; 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 allows 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.

12. A dispensing system as recited in claim 11 , in which:

the actuator member defines a first threaded portion; and

the adjustment member defines a second threaded portion; whereby

the first threaded portion engages the second threaded portion such that rotation of the adjustment member relative to the actuator member causes the adjustment member to act on the outlet member to alter the cross-sectional area of the outlet opening.

13. A dispensing system as recited in claim 11 , in which the propellant material is a pressurized fluid.

14. A dispensing system as recited in claim 11 , in which the propellant material is at least one pressurized fluid selected from the group consisting of air and nitrogen.

15. A dispensing system as recited in claim 11 , in which the propellant material is inert.

16. A dispensing system as recited in claim 11 , in which the propellant material is hydrocarbon material that exists within the container in a liquid state and in a gas state.

17. A dispensing system as recited in claim 11 , in which:

the actuator member defines a first threaded portion; and

the adjustment member defines a second threaded portion; whereby

the first threaded portion engages the second threaded portion such that rotation of the adjustment member relative to the actuator member causes the adjustment member to act on the outlet member to alter the cross-sectional area of the outlet opening.
