Description
SPECIFICATION
Beverage carbonation device
This invention relates to a device for providiny carbonated beverages and more particularly to such devices in which the beverage may be carbonated immediately prior to consumption.
Commercial production of carbonated beverages usually involves carbon dioxide-liquid contact under pressure with intensive mixing in a cooled container. Such commercial methods, however, require elaborate and sophisticated equipment not usually or conveniently available in the home or at the point of beverage consumption.
As a result, several beverage carbonation techniques which are suitable for home use have been developed in the art. One such technique utilizes carbon dioxide-containing molecular sieves which release the carbon dioxide upon contact with aqueous solutions to thereby provide a carbonated beverage. This technique is described in U.S. Patent Specifications Nos. 4,147,808; 4,110,225; 4,025,655 and 3,888,998.
Another known technique utilizes a chemical "couple" to generate carbon dioxide in situ within.
the beverage to be carbonated. Such a couple usually consists of a combination of an inorganic carbonate and an edible food acid. Contact between compounds of this type in aqueous solution results in the formation of gaseous carbon dioxide and a salt of the food acid. The chemical couple is usually added to the liquid to be carbonated in the form of a dry powder or a tablet. Such a technique is described in U.S. Patent Specification Nos. 2,851,360; 3,480,403; and 3,476,520. This technique however, is undesirable in that the salt of the food acid often imparts a brackish taste to the beverage.
Insoluble components of the reactants and products often produce particulate matter which results in a beverage with a cloudy appearance. Furthermore, when the beverage is consumed, the particulate matter is ingested along with the beverage.
We have now developed an improved beverage carbonation device which enables a clear carbonated beverage to be provided without a brackish taste and without any substantial quantity of insoluble material.
According to tiie present invention there is provided a beverage carbonation device for use in combination with a beverage vessel, the said beverage carbonation device comprising a container capable in use of being disposed in the beverage vessel and in communication with liquid therein, the said container being capable of containing a solid edible food acid and a solid inorganic carbonate which react together in the presence of water to form carbon dioxide and a substantially water-insoluble salt of the food acid, the said container being permeable to water and carbon dioxide but substantially nonpermeable to the solid inorganic carbonate and the solid edible food acid. Preferably the carbonation device is adapted for use in combination with a cup, but other beverage vessels such as glasses, jugs or vats may be used if appropriate or desired.
According to a further feature of the invention there is provided the above defined beverage carbonation device further including a cup.
The invention will now be further illustrated by reference to the drawings wherein:
Fig. 1 is a perspective view of a beverage carbonation device according to the present invention with a portion of the wall of the cup cut away to reveal the interior thereof.
Fig. 2 is a plan view of the bottom of the cup shown in Fig. 1.
Fig. 3 is a cross-sectional view taken along the line 3-3 of the cup bottom shown in Fig. 2.
Fig. 4 is a cross-sectional view of two of the cups shown in Fig. 1, one cup being stacked in the other.
Referring now to the drawing in which like numbers indicate like elements throughout the several views, it will be seen that there is a drinking cup 10 for holding a quantity of liquid beverage. The cup 10 includes a generally cone shaped side wall 12 and a flat base 14. Drinking cups or glasses are well known in the art as are other beverage vessels and the particular size and shape is not critical to the present invention. According to one preferred embodiment the cup 10 is made of disposable material such that it may be discarded after use. Such cups are preferably made from treated paper, plastic or other similar materials known for such purposes. It will be appreciated that the wall 12 and the base 14 should be impermeable to the beverage which is to be contained in the cup.
Disposed in the bottom of the cup 10 is an envelope 1 6 for containing a quantity of carbonating material. The envelope 1 6 includes the flat base 14 of the cup 10 and a selectively permeable membrane 1 8 sealed to the flat base around its peripheral edge 20. The carbonating material is contained in a chamber 22 defined between the flat base 14 of the cup 10 and the selectively permeable membrane 1 8. The envelope therefore includes a hemispherical portion and a flat annular portion, the hemispherical portion containing the carbonating material and the annular portion providing rigidity to the envelope as well as a means for securing the envelope to the bottom of the cup.Although the envelope is shown in the drawings as including the flat base of the cup, it is specifically contemplated that the envelope can be formed separately, e.g. from two pieces of material and subsequently attached to the bottom of the cup, for example by mechanical means or with a suitable adhesive. In this manner the base of the cup need not be relied upon for containing the carbonating material.
The carbonating material contained in the envelope includes a chemical "couple" which reacts in the presence of water in an acid neutralization reaction to produce carbon dioxide. In order to initiate the chemical reaction, water contained in the cup 10 must be allowed to pass into the chamber 22. The membrane 1 8 is therefore permeable to water. Similarly, the carbon dioxide produced by the chemical reaction in the chamber 22 must be able to pass into the beverage to be carbonated in the cup 10. The membrane is therefore permeable to carbon dioxide.
In order to prevent particulate matter from contaminating the beverage in the cup 10 and thereby produce a cloudy beverage, the membrane 1 8 is substantially non-permeable to the salt produced by the neutralization reaction and the crystalline forms of the chemical couple. The membrane 10 therefore provides a mechanical barrier to undesirable particulate matter which would otherwise contaminate the beverage and ultimately be ingested.
Many chemical "couples" are known which undergo acid neutralization reactions. Such "couples" include inorganic carbonates and edible food acids. However, not all such chemical "couples" are useful in the present invention. Only those inorganic carbonates and edible food acids which react to produce a substantially water-insoluble salt are useful in the present invention. The expression substantially waterinsoluble, as used herein, is intended to mean that the neutralization product, i.e., salt, is soluble to such an extent as to not adversely affect the taste of the beverage. Generally, solubility of less than one gram of salt per litre of water will not adversely affect the taste of the beverage and is considered substantially non-soluble. Such "couples" are used preferably in crystalline form.
A chemical "couple" which is particularly useful in the present invention is calcium carbonate and tartaric acid in solid and especially in crystalline form. It will be appreciated by those skilled in the art that calcium carbonate and tartaric acid react together in the presence of water to produce calcium tartrate which is substantially insoluble in water.
The selectively permeable membrane 1 8 should have a pore size suitable to provide the abovedescribed selective permeability. Additionally, the pore size of the membrane is ideally such that the carbon dioxide permeates the membrane on a molecular level; however, at such a size water would not usually pass through the membrane. If the pores of the membrane 18 are too big, the carbon dioxide will form large bubbles which then escape from the beverage; if the pores are too small, water will not pass through the membrane. Generally, it is found in accordance with the invention herein that conventional laboratory filter paper is a useful material for the selectively permeable membrane of the present invention.Preferred filter papers useful in the present invention include Filpaco #463TH, trademark of Filpaco Industries, Inc. and Schweitzer #855-45-2A and #855-46-2A, trademarks of
Kimberly Clark Corporation.

With particular reference to Fig. 4, it will be seen that there are two cups 1 0a, Ob in accordance with the present invention, the cup 1 Ob being received within the cup 1 Oa in a conventional stacked manner. When cups are stacked, as shown in Fig. 4, a space 24 is defined between the base 1 4b of cup 1 Ob and the base 1 4a of cup 1 Oa. It will therefore be appreciated by those skilled in the art that the position of the envelope in the bottom of the cup is particularly well suited for utilizing the space between the bases of stacked cups.
It is contemplated that flavour bases can be incorporated in the present invention to give colour and/or taste to the beverage. Flavour bases are well known in the art and are discussed in U.S. Patent
Specifications Nos. 4,041,185 and 3,966,994. The flavour base can be combined with the beverage liquid in one or more of the following ways: It can be separately added to the carbonated water in the cup 10; it can be included on the exterior surface of membrane 18; it can be included on the interior walls 12 of the cup; it can be included within the envelope 1 6 or other suitable means well known in this art. In this manner both a carbonated and a flavoured beverage can be provided.
It is specifically contemplated that the present invention can be used in instances where liquids containing other food acids, such as citric acid, are added to the beverage container. In such instances, substantially all of the calcium carbonate reacts with the tartaric acid in the envelope to form the substantially water-insoluble salt, calcium tartrate, rather than with the food acid in the liquid to form soluble salts which would undesirably affect the taste of the beverage. Therefore, conventional flavor bases which include other food acids can be used with the present invention.
The following example is provided to illustrate, but not limit, the present invention.
EXAMPLE 1
A paper cup capable of holding 100 ml of water and having a filter paper envelope in accordance with the present invention is prepared. The envelope contains 1.0 gram of calcium carbonate and 1.5 grams of tartaric acid. The calcium carbonate and tartaric acid are both in powdered crystalline form. To the cup is added 100 ml of water. The water penetrates the selectively permeable membrane of the envelope and contacts the carbonating material therein. The calcium carbonate and tartaric acid react together in the presence of the water to produce 0.44 grams of carbon dioxide, 0.18 grams of water and 1.88 grams of calcium tartrate. The filter paper prevents the calcium tartrate from escaping the envelope and contaminating the beverage. The calcium tartrate is substantially insoluble in water.
The beverage therefore has a clear appearance and is free from a brackish taste.
The 0.44 grams of carbon dioxide produced in the chemical reaction is equal to 224 ml of carbon dioxide as an ideal gas at standard temperature and pressure. The carbon dioxide permeates the membrane and is dissolved by the 100 ml of water in the cup. The beverage therefore has a relatively high level of carbonation.
