Abstract
Abstract A lightweight, portable post-mix carbonated beverage dispenser unit for use in small offices or small-volume locations is described. Flavored syrup is supplied to the unit from disposable sealed syrup packages which are plugged into a dispenser valving system. CO 2 is supplied to the unit carbonator system in returnable containers which also may be quickly plugged into a CO 2 valving system.

Claim 3
Independent Claim
222 words
A method for loading syrup supply containers, and CO 2 supply containers into a post-mix beverage dispenser unit, said dispenser unit including first socket means in a CO 2 pressure regulator valve assembly for receiving and supporting the discharge end and the weight of a CO 2 cylinder and second socket means in a beverage dispenser valve assembly for receiving and supporting discharge ends and the weight of syrup containers, comprising the steps of: providing syrup containers with discharge openings therein which are normally at the top of the container during storage and transportation; providing a CO 2 container with an opening in a discharge end that is normally at the top of the container during storage and transportation; inverting said syrup containers and plugging the discharge opening into said second socket means provided in the beverage dispenser valve assembly; inverting said CO 2 container and plugging the discharge opening into said first socket means provided in the CO 2 regulator valve assembly; and opening a valve between the discharge opening of said CO 2 container and said regulator valve assembly to initiate the flow of CO 2 from said CO 2 cylinder to said regulator valve assembly in response to the plugging of the discharge opening of said CO 2 container into the first socket means in the regulator valve assembly.
Claim 4
Independent Claim
222 words
A method for loading syrup supply containers, and CO 2 supply containers into a post-mix beverage dispenser unit, said dispenser unit including first socket means in a CO 2 pressure regulator valve assembly for receiving and supporting the discharge end and the weight of a CO 2 cylinder and second socket means in a beverage dispenser valve assembly for receiving and supporting discharge ends and the weight of syrup containers, comprising the steps of: providing syrup containers with discharge openings therein which are normally at the top of the container during storage and transportation; providing a CO 2 container with an opening in a discharge end that is normally at the top of the container during storage and transportation; inverting said syrup containers and plugging the discharge opening into said second socket means provided in the beverage dispenser valve assembly; inverting said CO 2 container and plugging the discharge opening into said first socket means provided in the CO 2 regulator valve assembly; and opening a valve between the discharge opening of said CO 2 container and said regulator valve assembly to initiate the flow of CO 2 from said CO 2 cylinder to said regulator valve assembly in response to the plugging of the discharge opening of said CO 2 container into the first socket means in the regulator valve assembly.
