Description:
ANTIFOAM BEVERAGE STIRRER OR STRAW BACKGROUND OF THE INVENTION 1. FIELD OF THE INVENTION The present invention relates to beverage dispensing. More specifically, it relates to a coating for a straw or beverage stirrer. Even more specifically, it relates to the coating of a straw or beverage stirrer with a silicone antifoaming agent. More generally, the invention relates to any application wherein the foaming of a liquid that is being poured into a container is not desired or needs to be discouraged. For example, the invention could be used in a food processing container or a fermentation vat by apply- ing the agent to an agitator before the material to be used is introduced. Thus it can be seen that the potential fields of use for this invention are myriad and the particular preferred embodiment described herein is in no way meant to limit the use of the invention to the particular field chosen for exposition of the details of the invention. A comprehensive listing of all the possible fields to which this invention may be applied is limited only by the imagination is therefore not provided herein. Some of the more obvious applications are mentioned herein in the interest of providing a full and complete disclosure of the unique properties of this previously unknown general pur- pose article of manufacture. It is to be understood from the outset that the scope of this invention is not limited

to these fields or to the specific examples of potential uses presented hereinafter. 2. DESCRIPTION OF THE PRIOR ART In busy food service establishments, bars, and espe- cially in an airliner environment, the server is often forced to wait for the foaming of carbonated beverages to subside before either continuing to decant the beverage or passing the customer the drink. This results in a large amount of "down time" where the employee is merely standing there looking at a fizzing glass. This is irritating for both the customer and the server, let alone the owner when there are clients waiting to be served. Additionally, the foaming liquid can overflow the glass, soiling the custom- ers or servers clothing. Thus, it is clear that an appa- ratus for retarding the foaming of a carbonated beverage would be advantageous for both the owner of the restaurant, bar, or airline, but would also be a boon to the customer as well. The present invention addresses this problem by providing a straw or stirrer that has coated on a portion thereof a silicone antifoaming agent. This allows for the placement of the coated object in the glass that is to be filled, and as the beverage is poured, the antifoaming agent is dispersed in the liquid. A search was conducted in the United States Patent and Trademark Office and number of patents were uncovered that relate to the instant inven- tion .

Firstly, U.S. Patent No. 2,613,988 issued on Octo- ber 14, 1952 to Charles F. Jarbeau discloses a beverage dispensing device. In this device, a straw or sipper made up of two telescopically engaged sections is placed inside a bottle. The upper portion is made of a material such that its specific gravity is less than the beverage, and the lower portion has a specific gravity higher than the beverage so that when the cap is removed, the upper portion rises to allow the user to drink from the bottle. This is clearly dissimilar from the present invention in that there is no mention of an antifoaming agent. Next is U.S. Patent No. 3,947,568 issued on March 30, 1976 to Barstow Bates et al. This discloses a cosmetic composition that includes liquified gasses entrained within a liquid stream under pressure. Though the disclosure discusses the use of a silicone antifoaming material as part of the composition, this patent does not discuss the coating of an object to be placed within a beverage recep- tacle as is required by the present invention. Another patent of interest is U.S. Patent No. 4,037,361 issued on July 26, 1977 to William R. Murphy et al. This discloses a hollow, flexible plant watering stick with a funnel shaped opening at the top surmounted by a decorative cap. This is clearly dissimilar from the present invention in that no antifoaming agent is taught for coating the stick.

Lastly, U.S. Patent No. 4,726,518 issued on Febru- ary 23, 1988 to Emanuela Martina et al . discloses a straw with a plurality of channels passing about a flattened portion designed for advertising or the like. As in the above mentioned patent, there is no teaching of an anti- foaming agent for coating of the portion of the straw that is to be inserted into the beverage. It will be noted that none of the prior art devices teaches an antifoaming agent coating on a straw or stirring device to prevent the foaming of carbonated liquids. None of the above inventions and patents, taken either singly or in combination, is seen to describe the instant invention as claimed. SUMMARY OF THE INVENTION Briefly, the invention comprises a coating of an antifoaming agent deposited on a stirring or straw element that is to be placed in a carbonated beverage receptacle. The disposition of this material on the object speeds up the pouring process and is useful in high volume environ- ments, such as airliners, convenience stores, and college bars. The preferred material for the coating is DOW CORNING ® Antifoam FG-10, which is a ten percent active, food grade silicon emulsion. Accordingly, it is a principal object of the invention to provide a new and improve beverage stirrer or straw

device which overcomes the disadvantages of the prior art in a simple but effective manner. It is another object of the invention to prevent overflow spillage onto customers or servers clothing from the foaming liquid. It is a major object of this invention to provide a stirrer or straw that speeds up the pouring process of a carbonated beverage, by inhibiting the foaming of the beverage as it is being poured. Finally, it is a general goal of the invention to provide improved elements and arrangements thereof in an apparatus for the purposes described which is inexpensive, dependable and fully effective in accomplishing its intended purposes. These and other objects of the present invention will become readily apparent upon further review of the follow- ing specification and drawings. The present invention meets or exceeds all the above objects and goals. Upon further study of the specification and appended claims, further objects and advantages of this invention will become apparent to those skilled in the art. BRIEF DESCRIPTION OF THE DRAWINGS Various other objects, features and advantages of the present invention will become more fully appreciated as the same becomes better understood when considered in conJune- tion with the accompanying drawing, in which like reference

characters designate the same or similar parts throughout the view, and wherein: The Figure shown is an environmental perspective view of the present invention in use. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention is shown in the Figure at 10. The stirrer, straw, or "swizzle stick" is indicated at 14 placed in a glass 12. A portion of the stirrer 14 is coated with an antifoaming agent. The portion of the stir- rer or straw 14 that is coated with the agent is indicated by the stippled area 16. Thus, the user, whose hand H is seen in the Figure, places the stirrer, straw, or other like object treated according to the present invention, in the glass 12 and then fills glass 12 with the carbonated liquid and the coating 16 on the stirrer or straw is dis- sipated through the liquid to lessen the amount of foam generated during the pouring process. Thus, the person pouring the drink is not required to wait for the foam to subside before topping off the glass or handing the bever- age to the customer, airline passenger, or the like. It should be noted that the stirrer shown in the Figure is of a solid type, it would be within the scope of the present invention to coat the outside of a hollow member, i.e. a straw, with the same material. As was mentioned previously, the preferred antifoaming ingredient for the application of the invention is Antifoam

StSSmUTE SHEET Hfll 26

FG-10 manufactured by DOW CORNING ® based in Midland, MI. This is a food grade antifoam silicone emulsion that com- plies with FDA Regulation 21 CFR 173.340, is permitted as a component of paper that would be brought into contact with foodstuffs, and is authorized by the USDA for use in federally inspected meat and poultry plants. The agent also has been certified for use in processing of kosher foods. The inventor has found that this material, applied directly to a straw or a stirring stick, substantially eliminates a large portion of the foaming that is normally present when a carbonated beverage is poured into a glass, speeding up the serving process. As the preferred material is concentrated, only a small portion of the straw or stirrer needs be coated. It is to be understood that the provided illustrative examples are by no means exhaustive of the many possible uses for my invention. From the foregoing description, one skilled in the art can easily ascertain the essential characteristics of this invention and, without departing from the spirit and scope thereof, can make various changes and modifications of the invention to adapt it to various usages and conditions. For example, the artisan could easily adapt the invention to a usage where the stirring member was machine driven, as

opposed to the hand manipulable object depicted in the drawing. It is to be understood that the present invention is not limited to the sole embodiment described above, but encompasses any and all embodiments within the scope of the following claims :
