Abstract
An apparatus and method of carbonating beverages is disclosed, including a container for the beverage to be carbonated and a source of carbon dioxide to be introduced into the beverage. The container is sealed, and a bleedline is provided for the headspace of the container, to maintain the pressure of the headspace at a sufficiently high value for carbonation to take place, while at the same time allowing the carbon dioxide to flow through the liquid. A source of carbon dioxide is disclosed which includes a reaction vessel and a chemical package containing a mixture of chemicals that can react in water to give carbon dioxide. The chemical package disclosed provides a time delay of at least ten seconds from the time it is immersed in water to the time the chemical reaction begins.
Claims4
A chemical package for a carbonation device including a reaction vessel filled with water, said chemical package comprising:
- a mixture of chemicals that react in the presence of water to generate carbon dioxide in an amount sufficient to carbonate a predetermined volume of liquid;
- a water impermeable covering having at least a first edge and a second edge and wherein said first edge is folded over said second edge to enclose said mixture of chemicals;
- and
- a water soluble means for adhering together at least said first and said second edges of said water impermeable covering to seal said mixture of chemicals within said water impermeable covering, said water soluble means dissolvable in water at a rate that maintains the package sealed and impermeable to water for at least about ten seconds thereby delaying the reaction of said mixture of chemicals with the water.
