Patent number: 7278590Abstract: An aerosol system for dispensing texture material on a horizontal surface comprising an aerosol assembly, an actuator member, and an outlet structure. The aerosol assembly, which is adapted to contain and dispense texture material, defines a container axis that is substantially vertical during normal use. The actuator member comprises a valve stem for engaging the aerosol assembly and defines a first portion of a dispensing path. The outlet structure defines a second portion of the dispensing path, an outlet orifice, and a dispensing axis. The outlet structure is arranged adjacent to the actuator member such that fluid flowing along the first portion of the dispensing path flows through the second portion of the dispensing path and the outlet orifice and generally along the dispensing axis. The dispensing axis is substantially aligned with the container axis. A cross-sectional area of the outlet orifice is adjustable.Type: GrantFiled: February 14, 2006Date of Patent: October 9, 2007Assignee: Homax Products, Inc.Inventors: Lester R. Greer, Jr., Donald J.

Patent number: 7240857Abstract: An actuator assembly for an aerosol system that dispenses texture material. The actuator assembly comprises an actuator member and an outlet structure. The actuator member comprises a valve stem that defines a first portion of a fluid path. The outlet structure defines a second portion of the fluid path and an adjustable outlet orifice. 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 outlet orifice. The spray pattern of the texture material flowing through the outlet orifice is determined by the cross-sectional area of the outlet orifice. The cross-sectional area of the outlet orifice is arranged such that the spray pattern of the texture material causes the texture material to be deposited on a target surface in a desired texture pattern that substantially matches a pre-existing texture pattern.Type: GrantFiled: April 9, 2005Date of Patent: July 10, 2007Assignee: Homax Products, Inc.Inventors: Donald J. Stern, James A. Tryon

Patent number: 7226001Abstract: An aerosol assembly for dispensing texture material. The aerosol assembly comprises a container, a valve assembly, an actuator member, and at least one outlet member. A stem portion of the actuator member engages a stem recess formed in a valve member to fix the actuator member relative to the container during normal use of the aerosol system. The valve assembly comprises a valve spring that biases the actuator member against a valve seat to place the valve assembly into a closed configuration. Applying a force to the actuator member compresses the valve spring to place the valve assembly into an open configuration. When the valve assembly is in the closed configuration, fluid is substantially prevented from flowing through an actuator passageway. When the valve assembly is in the open configuration, fluid may flow out of the container through the actuator passageway.Type: GrantFiled: June 14, 2005Date of Patent: June 5, 2007Assignee: Homax Products, Inc.Inventors: Donald J. Stern, James A. Tryon

Patent number: 7014073Abstract: An aerosol device for dispensing texture material for matching existing acoustical ceiling texture. The device comprises a container, a valve assembly, a dispensing nozzle, a hardenable material, and pressurized inert gas as a propelling mechanism. The hardenable material and pressurized inert gas are placed into the container. When the valve assembly is opened, the inert gas forces the hardenable material out of the container through the dispensing nozzle. The dispensing nozzle diverts at least a portion of the hardenable material exiting the container to develop a spray suitable for the application of the hardenable material onto the ceiling surface being textured. The hardenable material preferably comprises at least water, filler, binder, and polystyrene particles. The inert gas is preferably nitrogen.Type: GrantFiled: October 22, 2003Date of Patent: March 21, 2006Assignee: Homax Products, Inc.Inventors: Donald J. Stern, James A. Tryon, Eivind Clausen

Patent number: 5934518Abstract: An aerosol assembly for applying texture material to a surface in a plurality of pre-existing texture patterns. One or more actuator assemblies are employed, each one defining an outlet orifice having a different cross-sectional area. Each actuator assembly is associated with or can be reconfigured to be associated with a different pre-existing texture pattern. In one form, the actuator assemblies comprise a plurality of identical button members having an outlet chamber and a tube member inserted into the outlet chamber of each button member. The tube members define discharge passageways having different cross-sectional areas. The entire actuator assembly is removed and replaced to dispense a different texture pattern.
