Fluted funnel made of thick, clear molded glass with short stem cut at a diagonal. Includes manufacturer markings: "Mooney Air Vent." Jerome Henry Mooney applied for a patent for a funnel design on May 18, 1926, which is "a simple and practical construction wherein the funnel is supported in position upon the neck of a bottle in such manner that the air in the bottle will be effectively vented as liquid is poured into said bottle." The "double vent" fluting inside the stem of the funnel allowed for air to escape as a bottle or beaker is filled with liquid
