Abstract
A device for coating surfaces, particularly colored or painted surfaces, using a spray gun which is supplied by a supply device with the material to be sprayed. The supply device includes a material container which can be pressurized, and a pressure element is provided on or in the material container itself.
Claims29
A spray material containing device for coating surfaces with a sprayed material using a spray gun, the device comprising:
- a material container connectable to the spray gun, the container dimensioned to retain a supply of sprayed material;
- and
- a pressure generating element
- positioned on or only partially in the material container itself, and
- configured to one of
- (a) generate a displacement medium, and
- (b) release a displacement medium that is contained within the pressure generating element,
- into an interior of the material container so as to cause an increase in a pressure exerted upon the sprayed material within the container so as to force the sprayed material out of the container, the pressure generating element not connected to a remote source of pressurized medium,
- wherein the pressure generating element has a gas cartridge or is a gas cartridge or a spray can, the gas cartridge or spray can being able to be mounted and demounted at any time.
A spray material containing device for coating surfaces with a sprayed material using a spray gun, the device comprising:
- a material container connectable to the spray gun, the container dimensioned to retain a supply of sprayed material;
- and
- a pressure generating element
- positioned on or in the material container itself, and
- configured to one of
- (a) generate a displacement medium, and
- (b) release a displacement medium that is contained within the pressure generating element,
- into an interior of the material container to thereby cause an increase in a pressure exerted upon the sprayed material within the container to thereby force the sprayed material out of the container, the pressure generating element not connected to a remote source of pressurized medium,
- wherein the pressure generating element is a pump.
A spray material containing device for coating surfaces with a sprayed material using a spray gun, the device comprising:
- a material container connectable to the spray gun, the container dimensioned to retain a supply of sprayed material;
- and
- a pressure generating element positioned on or only partially in the material container itself, and configured to generate a displacement medium by releasing at least one reactive chemical into an interior of the material container to produce at least one of a foam, a gas, or an effervescence within the material container so as to cause an increase in a pressure exerted upon the sprayed material within the container so as to force the sprayed material out of the container, the pressure generating element not connected to a remote source of reactive chemical,
- wherein a ventilation mechanism including a ventilation opening is provided in a base of the material container, and the pressure generating element is connected to the material container via the ventilation opening.
A spray material containing device for coating surfaces with a sprayed material using a spray gun, the device comprising:
- a material container connectable to the spray gun, the container dimensioned to retain a supply of sprayed material;
- and
- a pressure generating element positioned on or only partially in the material container itself, and configured to generate a displacement medium by releasing compressed gas contained within the pressure generating element to release gas into an interior of the material container so as to cause an increase in a pressure exerted upon the sprayed material within the container so as to force the sprayed material out of the container, the pressure generating element not connected to a remote source of pressurized gas,
- wherein a ventilation mechanism including a ventilation opening is provided in a base of the material container, and the pressure generating element is connected to the material container via the ventilation opening.
