Abstract
An aerosol spray texture apparatus to dispense a spray texture material having particulate matter therein against a ceiling or other surface. There is a container having a spray texture material in the lower portion thereof, and inert compressed gas in the upper part of the container. A dispensing valve at the top of the container is depressed to cause the spray texture material to travel upwardly through a dispensing tube and from the valve onto the ceiling surface.
Claims20
An aerosol dispensing apparatus to dispense against a surface a spray texture coating material comprising a carrier fluid and particulate material contained in the carrier fluid, said apparatus comprising:
- a. an aerosol container defining a containing chamber having:
- i. a texture material chamber portion in which said texture material is contained;
- ii. a propellant chamber portion containing a propellant;
- iii. said container and said chamber portions being arranged so that there is a pressure interface between said propellant and said texture material;
- b. a discharge assembly having a discharge opening, an inlet opening, and valve means to control flow from said inlet opening to said discharge opening, said inlet opening being positioned to be in communication with said texture material in said texture material chamber portion, but substantially isolated from said propellant chamber portion;
- c. an entry chamber housing defining an entry chamber which is positioned to receive texture material from said inlet opening, said entry chamber communicating with said valve means to transmit said texture material through said valve means when said valve means is open;
- d. said apparatus having a closure sealing means comprising a perimeter edge portion of a collar means for said valve means, an inner circumferential edge portion of a top wall of the container, and an upper edge portion of said entry housing, the upper edge portion of the entry chamber housing being positioned between said perimeter edge portion of the collar means and the edge portion of the top wall of the container,
- whereby an effective seal is formed for said entry chamber, and also for said containing chamber.

An aerosol dispensing apparatus to dispense against a surface a spray texture coating material, said apparatus comprising
- a. an aerosol container defining a containing chamber and having an upper dispensing end and a lower end;
- b. said spray texture material being located in said chamber and comprising a carrier fluid with particulate material distributed throughout said carrier fluid;
- c. a pressurized gaseous propellant which is inert, relative to the particulate material, being located in said chamber;
- d. said container and said chamber being arranged so that with the container upright, the spray texture material is in the lower part of said chamber, said gaseous propellant is in an upper part of said chamber, and there is a pressure interface between said propellant and said texture material;
- e. a discharge assembly comprising an infeed section having tube means with an inlet opening positioned at a lower end of said chamber to receive the texture material flowing into said tube means, and a manually operable valve section having a discharge nozzle, said valve section being operatively connected to said infeed section to control flow of the texture material from said inlet opening to said discharge nozzle;
- whereby with said container upright, said spray texture material can be expelled from said container through said nozzle discharge by expansion of side pressurized gas acting against said spray texture material in said container.
3 more elements
A method of providing and dispensing a spray texture coating material against a surface, said method comprising
- a. providing an aerosol container defining a containing chamber and having an upper dispensing end and a lower end, and containing a spray texture material comprising a carrier fluid with particulate material distributed throughout said carrier fluid;
- b. providing in said chamber a pressurized gaseous propellant which is inert, relative to the particulate material being located in said chamber, in a manner that with the container upright, the spray texture material is in the lower part of said chamber, said gaseous propellant is in an upper part of said chamber, and there is a pressure interface between said propellant and said texture material;
- c. providing a discharge assembly comprising an infeed section having tube means with an inlet opening positioned at a lower end of said chamber to receive the texture material flowing into said tube means, and a manually operable valve section having a discharge nozzle and a valve, said valve section being operatively connected to said infeed section, and operating said valve to cause flow of the texture material from said inlet opening and through said discharge nozzle by expansion of side pressurized gas acting against said spray texture material in said container.
