Self-foaming ready to drink beverages

Abstract

A container stores a main liquid component that contains a dissolved gas, preferably nitrous oxide, separately from a foam initiator component that is at least one of a powder, a liquid or a concentrate. A dispensing part of the container, such as a dispensing lid, can contain the foam initi-ator component. The foam initiator component is dispersed and dissolved into the main liquid component to form a foaming ready to drink beverage. The foam initiator component comprises a portion of the ingredients of the ready to drink beverage. Combination of the foam initiator component with the main liquid component not only results in foam generation in the contain-er without any mechanical energy input additional to the opening of the container but also forms the ready to drink beverage.

The invention is claimed as follows: 
     
         1 . A ready to drink beverage comprising:
 a foaming initiator component comprising a medium selected from the group consisting of a powder and a liquid; and   a main liquid component comprising dissolved gas, the foaming initiator component stored separately from the main liquid component, the beverage formed by addition of the foaming initiator component to the main liquid component.   
     
     
         2 . The ready to drink beverage of  claim 1 , wherein the main liquid component comprises water in which selected from the group consisting of nitrous oxide (N20), carbon dioxide (CO 2 ) and a combination thereof is dissolved. 
     
     
         3 . The ready to drink beverage of  claim 1 , wherein the foaming initiator component comprises a coffee ingredient selected from the group consisting of a soluble coffee powder and a coffee concentrate. 
     
     
         4 . The ready to drink beverage of  claim 3 , wherein the main liquid component comprises coffee aroma. 
     
     
         5 . The ready to drink beverage of  claim 1 , wherein the foaming initiator component comprises a tea ingredient selected from the group consisting of a soluble tea powder and a tea concentrate. 
     
     
         6 . The ready to drink beverage of  claim 1 , wherein the foaming initiator component comprises a fruit ingredient selected from the group consisting of a fruit powder and a fruit concentrate. 
     
     
         7 . The ready to drink beverage of  claim 1 , wherein the foaming initiator component comprises a cocoa ingredient selected from the group consisting of a cocoa powder and a cocoa concentrate. 
     
     
         8 . A foaming ready to drink beverage formed by dispensation of a foaming initiator component from a dispensing part of a container into a main liquid component comprising dissolved gas and stored in the container separately from the foaming initiator component, the foaming initiator component comprising a medium selected from the group consisting of a powder and a liquid. 
     
     
         9 . A container comprising:
 a foaming initiator component comprising a medium selected from the group consisting of a powder and a liquid; and   a main liquid component comprising dissolved gas and stored in the container separately from the foaming initiator component, the container configured to dispense the foaming initiator component into the main liquid component upon opening of the container, and dispensation of the foaming initiator component into the main liquid component forms a foaming ready to drink beverage in the container.   
     
     
         10 . The container of  claim 9 , comprising a dispensing part that stores and dispenses the foaming initiator component.
