A vacuum insulated carafe having high flow characteristics is taught, which includes a double wall metallic body (22) with the air evacuated from the space between the walls forming an insulating layer. The body has a top (26) and a bottom (28) with a base (30) attached to the bottom for resting the carafe on a flat surface. A mounting ring (34) is connected to the top of the body and includes a outside surface (36) and a central opening (38), with the outside surface having a pouring spout (40) and a handle (50). An interfacing gasket (54) seals the mounting ring to the body and a stopper (58), having a cap (70), an inner cup (60) and an outer ring (62) containing external male threads, and a plurality of integral ribs (68) connect the cup to the ring while forming a void (68) between the ribs. A liquid sealing gasket (72) is disposed between the stopper and the mounting ring. In operation, the stopper is screwed in until it contiguously engages the ring for sealing and when the stopper is unscrewed, a horizontal gap is formed between the sealing gasket and the ring, providing a passageway through the gap and the void that is formed between the ribs, permitting a high flow of liquid to pour from the carafe.

The vacuum insulated carafe as recited in claim 1 wherein said handle is of a resilient material and said handle further comprises a separate bottom cover.9. The vacuum insulated carafe as recited in claim 1 wherein said handle further comprises a top thumb portion of resilient material.10. The vacuum insulated carafe as recited in claim 1 wherein said handle is joined to said mounting ring with a threaded fastener.11. The vacuum insulated carafe as recited in claim 1 wherein said interfacing gasket is selected from the group consisting of silicone, natural rubber, synthetic rubber, thermoplastic, neoprene, and viton.12. The vacuum insulated carafe as recited in claim 1 wherein said stopper is formed of a thermoplastic selected from the group consisting of cellulose, phenolic, phenylene oxide, polycarbonate, polyester, polyethylene, polypropylene, polystyrene, acetyl, polyester, phenylene oxide, polymide and poly vinyl cloloride.13. The vacuum insulated carafe as recited in claim 1 wherein said ribs extend exclusively between the cup and the ring and are angularly formed on a lower end to offset parallel misalignment of the cup to the ring.14. The vacuum insulated carafe as recited in claim 1 further comprising said rib having a width of not more than 0.036 times its diameter.15. A vacuum insulated carafe with a stopper having high flow characteristics comprising, an insulated body, having a top and a bottom, a base attached to the bottom of the body, for resting the carafe on a flat surface, a mounting ring connected to the top of the body, having a pouring spout, handle attachment means and internal threads within a central opening, a handle, adjoined onto the mounting ring with attaching means, a stopper, having an inner cup, an outer ring and a cap, said outer ring containing external male threads, and a plurality of integral ribs connecting the cup to the ring forming a void between the ribs, a liquid sealing gasket creating a sealing surface between the stopper and the mounting ring, for sealing the stopper to the mounting ring when the stopper contiguously engages the ring, further, when the stopper is unscrewed a horizontal gap is formed between the gasket and the mounting ring and, along with the void between the ribs, provides a high flow liquid passageway from the carafe. 16. A vacuum insulated carafe with a stopper having high flow characteristics comprising, a body, having a top and a bottom, a base attached to the bottom, for resting on a flat surface, a mounting ring connected to the top having a pouring spout and a handle also internal threads within a central opening, a stopper, having at least, an inner cup and an outer ring, said outer ring containing male threads and a plurality of integral ribs, connecting the cup to the ring forming a void between the ribs, a liquid sealing gasket creating a sealing surface between the stopper and the mounting ring, when the stopper is unscrewed with the threads a horizontal gap is formed between the gasket and the mounting ring and, along with the void between the ribs, providing a passageway for liquid to flow from the carafe.
