Aerosol spray texturing systems and methods
View Patent ↗A system for forming a coating having a desired texture pattern that substantially matches a pre-existing texture pattern. The system comprises an aerosol assembly, texture material, propellant, and an outlet structure. The aerosol assembly comprises a container assembly defining a product chamber, a valve assembly, and an actuator member defining a nozzle opening. The texture material is arranged within the product chamber. The propellant is arranged within the product chamber to pressurize the texture material. The outlet structure defines an outlet orifice. The outlet structure is fixed relative to the actuator member such that fluid flowing along a fluid path flows through the outlet orifice and onto a surface in the desired texture pattern.
1. A system for forming a coating having a desired texture pattern that substantially matches a pre-existing texture pattern, comprising:
an aerosol assembly comprising
a container assembly defining a product chamber,
a valve assembly secured to the container assembly, and
an actuator member defining a nozzle opening, where a first portion of a fluid path extends between the container assembly and the nozzle opening when the valve assembly is in an open configuration;
texture material arranged within the product chamber;
propellant arranged within the product chamber for causing the texture material to flow along the first portion of the fluid path when the valve assembly is in the open configuration; and
outlet structure for defining an outlet orifice and a second portion of the fluid path, where the outlet structure is arranged adjacent to the actuator member such that fluid flowing along the first portion of the fluid path flows through the second portion of the fluid path and the outlet orifice; whereby
the cross-sectional area of the outlet orifice is determined based on the pre-existing texture pattern; and
the valve assembly is operated to cause the propellant to force the texture material out of the product chamber and through the outlet orifice such that the desired texture pattern substantially matches the pre-existing texture pattern.
2. A system as recited in claim 1 , in which:
the outlet means comprises a plurality of straws each defining a straw bore having a different cross-sectional area; and
one of the straws is attached to the actuator member to determine the cross-sectional area of the outlet orifice.
3. A system as recited in claim 1 , in which the outlet means comprises an outlet member defining a plurality of outlet openings each having a different cross-sectional area, where the outlet member is movably attached to the actuator member such that one of the plurality of outlet openings determines the cross-sectional area of the outlet orifice.
4. A system as recited in claim 1 , in which the outlet means comprises:
a deformable first member defining an outlet opening; and
a second member movably mounted adjacent to the first member; whereby
the first member is secured relative to the actuator member such that the outlet opening forms the outlet orifice; and
the second member is moved relative to the first member to deform the first member to determine the cross-sectional area of the outlet opening.
5. A method of forming a coating on a surface such that the coating has a desired texture pattern that substantially matches a pre-existing texture pattern, comprising:
arranging texture material within a product chamber;
arranging a propellant within the product chamber, where the propellant pressurizes the texture material within the product chamber;
defining a fluid path between the product chamber and an outlet orifice;
determining a cross-sectional area of the outlet orifice based on the pre-existing texture pattern; and
operating a valve assembly to allow the propellant to force the texture material out of the product chamber, along the fluid path, through the outlet orifice, and onto the surface in the desired texture pattern.
6. A method as recited in claim 5 , in which the step of determining the cross-sectional area of the outlet orifice comprises the steps of:
providing a plurality of straws each defining a straw bore having a different cross-sectional area; and
attaching one of the straws to the actuator member to determine the cross-sectional area of the outlet orifice.
7. A method as recited in claim 5 , in which the step of determining the cross-sectional area of the outlet orifice comprises the steps of:
providing an outlet member defining a plurality of outlet openings each having a different cross-sectional area; and
arranging the outlet member adjacent to the actuator member such that one of the plurality of outlet openings determines the cross-sectional area of the outlet orifice.
8. A method as recited in claim 5 , in which the step of determining the cross-sectional area of the outlet orifice comprises the steps of:
securing a deformable member defining an outlet opening relative to the actuator member such that the outlet opening forms the outlet orifice; and
deforming the deformable member to determine the cross-sectional area of the outlet opening.
