The present invention relates to a drinking device which, after suitable refrigeration, acts as a heat exchanger to draw heat from a hot liquid, thereby delivering cooled beverage to the user\s mouth. The device includes flexible, concentric inner and outer tubes, the inner tube comprising a length of flexible, beverage grade tubing having an outer diameter at least 1/16 of an inch less than the inner diameter of the outer tube and a length at least thirty percent greater than that of the outer tube. An air space between the tubes is filled with a thermally conductive, non-toxic solid, forming the heat exchanger portion of the device. The outer tube is attached to the inner tube in a first position, such that an exposed small section of the inner tube forms a mouthpiece, and at a second position, such that the air space is formed, and at least two inches in length of the inner tube which is exposed beneath the second position forms an intake end, whereby the heat exchanger portion remains essentially unsubmerged in the beverage, thereby cooling only liquid drawn up by the user.

A drinking device for modulating the temperature of fluids drawn therethrough by a user\s mouth, said device acting as a heat exchanger to draw heat from about liquid and thereby deliver cooled beverage to the user\s mouth, said device comprising a flexible outer tube having a first cross-sectional
A drinking device for modulating the temperature of fluids drawn therethrough by a user\s mouth, said device acting as a heat exchanger to draw heat from about liquid and thereby deliver cooled beverage to the user\s mouth, said device comprising a flexible outer tube having a first cross-sectional area, said outer tube comprising a length of flexible tube and having a first inner diameter and a first outer diameter, said outer tube having placed concentrically therewithin an inner, cylindrical tube, said inner tube comprising a length of flexible, beverage grade tubing having a second inner diameter and a second outer diameter at least 1/16 of an inch less than the inner diameter of said outer tube, said inner tube further having a length at least thirty percent greater than that of said outer tube, said inner tube and said outer tube having a heat exchanger between their opposite surfaces, said heat exchanger comprising an air space filled with a thermally conductive, non-toxic solid, the upper end of said outer tube being attached proximate to the upper end of said inner tube in a first position such that a small section of inner tube comprising a mouthpiece is exposed above said first position, and the lower end of said outer tube being attached to said inner tube at a second position such that a section of at least 2 inches in length of said inner tube comprising an intake end is exposed below said second position, said thermally conductive, non-toxic solid being sealed between the opposite surfaces of said inner tube and said outer tube between said first position and said second position, whereby said heat exchanger portion of said device, after suitable refrigeration, remains essentially unsubmerged in said beverage thereby allowing the bulk of the beverage to retain its hot temperature while said heat exchanger portion cools only that liquid drawn therethrough by the user\s mouth.
