Abstract
A separation means is disclosed which effectively isolates the resultant salts of a carbonation reaction while permitting the transfer of gaseous carbon dioxide in a substantially pure, non-contaminated form to a liquid to be carbonated. The separation means comprises a passageway with a plurality of restricted gas communicating apertures and a one-way valve attached to the end of the passageway which is proximate to the liquid to be carbonated. The gas communicating apertures and one-way valve function to retain the chemical by-products of the reaction from the carbonated beverage.
