Abstract
A packaged gas-solubilized product is described. The gas-solubilized product contains a first gas with a first pressure. The product is placed into a flexible inner container made of a gas-impermeable material. The inner container is hermetically disposed inside an outer container. A space formed between the inner and the outer containers is charged with a second gas with an initial charging pressure. The initial charging pressure is higher than the pressure of the first gas contained in the product. Additionally, a product dispenser in a fluid connection with the product contained in the internal container is included. The present invention also provides a method of packaging a gas-solubilized product to prevent a change in the concentration of the gas dissolved in the product during its storage and dispensing.
