Abstract
A gas-propelled dispensing device for a liquid container has a high pressure vessel and a pressure gas vessel. A pressure reducing valve is provided between the two vessels so that as consumed, replacement gas is supplied to the low pressure chamber at a controlled moderate pressure. A relatively long tube delivers liquid from the bottom of the container, and a gas duct in the discharge head is connected to the low pressure vessel. Both ducts are opened by pressing the discharge head so that gas flows through a venturi passageway to draw liquid from the container which is propelled outward by the gas in a spray. Liquid carbon dioxide is a preferred nontoxic, nonflammable source of the gas propellant.
