Abstract
Abstract A process for the preparation of carbonated beverages by the consumer is disclosed. Water is contacted with carbonated ice and, optionally, flavored syrup in a closed pressure vessel whereby superatmospheric pressure is created and a carbonated liquid is produced. Soft drinks prepared by this method have a degree of carbonation substantially the same as the bottled or canned product available commercially.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
65 words
A method of carbonating water which comprises contacting water with carbonated ice initially at substantially normal atmospheric pressure in a closed pressure vessel, the carbonated ice containing at least 25 ml of carbon dioxide per gram of ice, the amount of carbonated ice being sufficient to create a superatmospheric pressure in said vessel and provide carbonated water containing at least three volumes of carbon dioxide.
Claim 2
Independent Claim
65 words
A method of carbonating water which comprises contacting water with carbonated ice initially at substantially normal atmospheric pressure in a closed pressure vessel, the carbonated ice containing at least 25 ml of carbon dioxide per gram of ice, the amount of carbonated ice being sufficient to create a superatmospheric pressure in said vessel and provide carbonated water containing at least three volumes of carbon dioxide.
Claim 3
Dependent Claim
21 words
A method according to claim 1 wherein the water contains sweetener and flavor and the carbonated water is a carbonated beverage.
Claim 4
Dependent Claim
66 words
A method according to claim 1 wherein said contacting is accomplished by the steps of: (a) adding water to said vessel while retaining a head space; (b) inserting said carbonated ice into said head space out of contact with the water; (c) closing said vessel to the atmosphere; and (d) altering the position of the closed pressure vessel so that the water contacts the carbonated ice.
Claim 5
Dependent Claim
57 words
A method according to claim 3 wherein the head space comprises up to about 50 volume percent of the total internal volume, and the amount of carbonated ice produces, at the completion of the carbonation process, a pressure of about 10-120 psig in said head space and a carbonated liquid having a carbonation volume greater than 3.
Claim 6
Dependent Claim
20 words
A method according to claim 1 wherein the carbonated ice contains 25-118 ml. of carbon dioxide per gram of ice.
Claim 7
Dependent Claim
24 words
A method according to claim 5 wherein the carbonated ice contains about 35 to about 90 ml. of carbon dioxide per gram of ice.
Claim 8
Dependent Claim
76 words
A method according to claim 1 wherein said contacting is accomplished by the steps of: (a) adding water to said vessel while retaining a head space; (b) inserting said carbonated ice into said vessel so that said carbonated ice is in contact with the water; (c) closing said vessel to the atmosphere; and (d) altering the position of the closed pressure vessel so that the carbonated ice is entirely retained beneath the surface of the water.
Claim 9
Dependent Claim
77 words
A method according to claim 1 wherein said contacting is accomplished by the steps of: (a) adding water to said vessel while retaining a head space; (b) inserting said carbonated ice into said vessel so that said carbonated ice is out of contact with the water; (c) closing said vessel to the atmosphere; and (d) altering the position of the closed pressure vessel so that the carbonated ice is entirely retained beneath the surface of the water.
