Abstract
Abstract Free carbon dioxide gas is injected as small bubbles into a number, less than all, of portions of carbonated beverage which are successively intermittently transferred to an area of reduced temperature for cooling such portions to serving temperature and to mix with and to replenish previously transferred portions. One specific type of apparatus for carrying out this method includes an aperture in an outlet tube that extends into a carbonator and is located so that it becomes alternately submersed in carbonated beverage stored in a carbonator and exposed to pressurized carbon dioxide gas above such liquid in the carbonator.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
42 words
Apparatus for producing and dispensing a carbonated beverage according to claim 1, wherein said aperture is located nearer the level of said predetermined minimum amount of carbonated beverage than it is to the level of said predetermined maximum amount of carbonated beverage.
Claim 2
Dependent Claim
24 words
Apparatus for producing and dispensing a carbonated beverage according to claim 2, wherein said aperture is located about one-sixth the distance between said levels.
Claim 3
Dependent Claim
34 words
Apparatus for producing and dispensing a carbonated beverage according to claim 1, wherein said refrigeration means has the refrigerating capacity to freeze a portion of said carbonated beverage while in said heat transfer member.
Claim 4
Independent Claim
106 words
A method for producing and dispensing a foamy carbonated beverage, comprising: a. combining water, syrup and pressurized carbon dioxide gas in a chamber to provide a stored quantity of several servings of the carbonated beverage; b. intermittently transferring portions of said quantity of carbonated beverage, each proportional to a serving dispensed, to an area of reduced temperature to cool such portions to serving temperature, and to mix with and to replenish previously transferred portions; c. injecting free carbon dioxide gas as small bubbles directly into a number, less than all, of such transferred portions during their transfer; and d. withdrawing servings of the refrigerated carbonated beverage.
Claim 5
Dependent Claim
32 words
A method for producing and dispensing a foamy carbonated beverage according to claim 5, wherein the number of transferred portions into which free carbon dioxide gas is injected is less than one-half.
Claim 6
Dependent Claim
20 words
A method for producing and dispensing a foamy carbonated beverage according to claim 6 wherein said number is about one-sixth.
Claim 7
Dependent Claim
36 words
A method for producing and dispensing a foamy carbonated beverage according to claim 5, wherein the free carbon dioxide gas that is injected is injected at the pressure of the carbon dioxiDe gas in said chamber.
Claim 8
Dependent Claim
22 words
A method for producing and dispensing a foamy carbonated beverage according to claim 5, wherein the serving temperature is below 28* F.
Claim 9
Dependent Claim
24 words
Apparatus for producing and dispensing a foamy carbonated beverage according to claim 1, wherein said aperture has a diameter of about one thirty-second inch.
