Spray gun system
First Claim

1. A self-contained, portable, pressurized spray gun system for texturing a surface comprising:
- a spray gun body having a handle and a main barrel with an upper surface, the main barrel defining a passageway connecting an inlet port to a spray outlet defining an expanding spray profile;
a cartridge seat projecting from the upper surface of the main barrel and having a bore in communication with the passageway of the main barrel;
a single spray valve projecting at least partially through the main barrel of the spray gun body and constructed to travel between a first position projecting into and sealing off the spray outlet while leaving the remainder of the passageway open and a second position withdrawn from and at least partially opening the spray outlet;
a single cartridge including a release valve sealing off a single cartridge opening, the cartridge being pre-filled and pre-pressurized with a volume of sprayable texture material and a propellant prior to releasably coupling the cartridge to the cartridge seat with the release valve being constructed to open and allow at least a portion of the sprayable texture material to enter the passageway through the bore of the cartridge seat under a combined pressure and gravity feed to load a volume of sprayable texture material proximate an outer end of the spray outlet with the cartridge releasably coupled to the cartridge seat in an inverted orientation; and
a trigger coupled to the spray valve and constructed to transition the spray valve between the first position and the second position allowing at least a portion of the sprayable texture material proximate the spray outlet to spray out through the spray outlet and expand outwardly through the expanding spray profile to produce an orange peel or knockdown texture pattern on the surface.

Abstract
A portable, self-contained, hand-held, spray gun system having spray gun with a handle, barrel, trigger, and an interchangeable cartridge containing a sprayable substance which may flow from the cartridge under pressure through a portion of the barrel past a selectively positionable needle valve and out an exit orifice of a nozzle when the trigger is squeezed allowing a user to spray the pressurized contents of the vessel over a selected surface and stop such spraying activity by releasing the trigger all without the need for a separate power source or motorized compressor.

24. A portable, hand-held, motorless, spray gun for use with a single cartridge pre-filled and pre-pressurized with a volume of sprayable texture material and a propellant and having a release valve sealing a single cartridge opening and further having a mounting collar, the spray gun comprising:
-
a spray gun body having a handle extending from a main barrel with an upper surface and defining a passageway connecting an inlet port to a spray port defining an expanding spray profile constructed to produce an orange peel or knockdown texture spray pattern on a desired surface toward which the spray port is pointing when at least a portion of the volume of sprayable texture exits through the spray port; a single cartridge seat projecting from the upper surface of the main barrel in a direction tilted toward the spray port of the main barrel and including a connector for coupling the cartridge seat to the mounting collar of the cartridge and opening the release valve to unseal the single cartridge opening of the cartridge upon engagement with the cartridge seat to allow the contents of the cartridge to enter the inlet port of the passageway through a bore passing through the cartridge seat; a spray valve projecting at least partially through the gun body and operable to transition from a first position extending into and seal off an outer end of the spray port to a second position withdrawn from and at least partially opening the spray port; a trigger coupled to the spray valve and constructed to open and close the spray port by actuating the spray valve; and wherein the mounting collar of the cartridge may be releasably engaged with the cartridge seat in an inverted orientation to open the release valve to allow at least a portion of the volume of sprayable texture material of the cartridge to flow under a combined pressure and gravity feed through the bore of the cartridge seat and into inlet port and load a quantity of the volume of sprayable texture material proximate the spray port until a user squeezes the trigger to actuate the spray valve to allow at least a portion of the volume of sprayable texture material to exit through the spray port and expand through the expanding spray profile to produce an orange peel or knockdown texture spray pattern on a desired surface. - View Dependent Claims (25)
