Embodiment Construction

[0043] The beverage product of the present invention includes a dispenser and a pressurized beverage.

[0044] The dispenser has a container adapted to hold a beverage under pressure and a valve that can be opened to allow the beverage to be expelled from the dispenser as a frothed fluid.

[0045] The beverage contains poorly soluble foam inducing gas dissolved therein. The gas may be oxygen, nitrogen, nitrous oxide, hydrogen, noble gases, gaseous hydrocarbons or their compounds. Oxygen is particularly preferred because it is non-toxic, not asphyxiating, and safe at elevated temperatures. If desired, it is also possible to dissolve in the beverage other gases listed above which are more easily soluble in water, such as carbon dioxide, the partial pressure of which in the headspace does not exceed one atmosphere absolute at 18°C.

[0046] The poorly soluble froth-inducing gas should dissolve in the beverage under the action of the gas pressure in the headspace, which should b...

Abstract

A beverage product that comprises a dispenser and a pressurised beverage. The dispenser has a container for holding the beverage and a valve. The beverage has a sparingly soluble effervescence inducing gas dissolved therein and is held under a gaseous pressure in the head space of the container that is sufficient to cause the beverage to be discharged from the dispenser as an effervescent fluid when the valve is open.

Description

technical field [0001] The present invention relates to a beverage product comprising a dispenser and a pressurized beverage comprising a poorly soluble foam-inducing gas dissolved therein. The dispenser has a valve that can be opened so that the beverage can be dispensed as a fizzy fluid. Background technique [0002] Carbonated beverages such as mineral water, soft drinks and iced tea are very common consumer products. Carbon dioxide is easily soluble in water, the solubility in water is 1.69g / kg at 20°C and atmospheric pressure, and it is cheap, widely used and harmless. When carbon dioxide is mixed with drinking liquid in a container under pressurized conditions, most of the gas remains dissolved in the drinking fluid when the container is opened to the atmosphere. In this way, if desired, the container can be kept open for a short period of time, during which time the taste of the gas-containing liquid will change minimally. The carbonated drink is usually served in ...
