A liquid carbonating and dispensing device comprising a container: a vessel within said container; insulation between said container and said vessel; at least one pocket between said insulation and said vessel to insert cartridge means filled with a freezeable substance; an opening at the upper end of said vessel; a hollow cylinder freely fitted within said opening to project concentrically downwardly within said vessel to form an air pocket between the outer surface of said cylinder and the inner surface of said vessel; a cap removably securable to the upper end of said vessel; a carbon dioxide capsule chamber formed in said cap; a check valve chamber formed in said cap adjacent said capsule chamber; a partition between said chambers having an opening therethrough; needle and check valve means in said check valve chamber with said needle projecting through said partition opening and into said capsule chamber; means to urge said capsule against said needle to pierce said capsule; a first port in said check valve chamber; a combination charging and dispensing tube secured at one end to said first port and extending into said vessel with its opposite end adjacent the lower end of said vessel; a dispensing valve chamber formed in said cap; a dispensing valve in said dispensing valve chamber; a second port in said check valve chamber connecting said check valve chamber and said first port with said dispensing valve chamber; a port in said dispensing valve chamber selectively connectable by said dispensing valve to said check valve chamber second port; and a dispensing nozzle in communication with said dispensing valve chamber port; whereby, with said dispensing valve blocking communication between said check valve chamber second port and said dispensing valve chamber port, when said carbon dioxide capsule is pierced, carbon dioxide gas forces said check valve open and passes down said charging and dispensing tube into said vessel and whereby, with said dispensing valve unblocking communication between said check valve chamber second port and said dispensing valve chamber port, carbon dioxide gas returns up said charging and dispensing tube, through said first and second check valve chamber ports, said dispensing valve chamber port and out of said dispensing nozzle. In a carbonated beverage making and dispensing mechanism having a beverage containing body with a necked-in top opening and a dispensing cap removably secureable to said necked-in opening and having a dispensing nozzle projecting therefrom, the improvement comprising: a vertical passageway in said cap open at the top; a manual actuating plunger received within said passageway and having an upper end substantially flush with the top surface of said cap, said passageway and said plunger being positioned immediately adjacent said dispensing nozzle; a lever having one end inward from said plunger and pivotally fixed to said cap and a free end remote from said cap, whereby said lever may be pivoted forwardly to overlap said plunger and to project over and in alignment with said dispensing nozzle and whereby downward pressure on the free end of said lever in said forward position will actuate said plunger, wherein said cap includes a U-shaped handle having front and back legs and a horizontal bridge therebetween, said handle being in longitudinal alignment with said dispensing nozzle; said vertical passageway extending upwardly in said front leg and said lever being recessed in a U-shaped trough in said horizontal bridge, and wherein said lever fills said U-shaped trough so that the top surface of said lever is in the same horizontal plane as the top edges of said U-shaped trough.
