Abstract
An arrangement for carbonating a solution by pressurization of a defined spatial area in a container in which a carbonating mixture is combined with a solution. The container is typically filled with a solution to a demarcation defining a spatial area. Reactants, an acid and a base, evolve CO.sub.2 when reacted in a solution. The quantity of reactants added is designated so as to generate a quantity of CO.sub.2 which will increase the pressure in a defined spatial area and cause a quantity of CO.sub.2 to redissolve. The result of this arrangement is a solution supersaturated with CO.sub.2. The reaction chamber may also be divided into separate compartments with each compartment containing individual servings. Each compartment has an evacuation device allowing the contents of the compartment to be delivered for consumption without effecting the level of carbonation of the solution remaining in the other compartments of the container. The separate compartments of the container also allow the solution of each compartment to be individually flavored, if desired.
