Abstract
A device for dispensing a viscous material and a method for controlling the dispensing pressure. The device has a manually actuated control valve, that, when depressed, releases high pressure gas from the source, such as a CO2 cartridge, into a gas enclosure. An indicator signals a pre-determined pressure in the gas enclosure sufficient to forcefully dispense a viscous material from a product cartridge.
