Heat-exchanging devices for cooling or heating liquids in a bottle or can, which include in a first embodiment, an elongated cooling or heating tube having a tube bore filled with a refrigerant/heating fluid such as water and sealed at the top, with liquid flow openings provided in the tube, or in a tube connector attached to the tube above a tube seal. The tube or tube connector is fitted with a cap having internal threads for engaging the external threads of the bottle neck of the bottle into which the cooling tube is inserted. In second and third embodiments the insertable tube contains a pair of interconnected reservoirs containing liquids that will create an exothermic or endothermic reaction when mixed. A disc separating the liquids is ruptured by button action at the base of the tube to facilitate mixing of the liquids by gravity. Access to the cooled or heated liquid in the bottle is gained in each case by inverting the bottle in conventional manner to allow a flow of liquid from the bottle through the openings in the upper portion of the tube or the tube connector and into a spout provided in the cap, for drinking purposes. In a preferred embodiment a sports valve may be provided on the spout for sealing the spout against inadvertent leakage or spillage of the contents of the bottle.

The invention claimed is: 1. A device for cooling or heating a liquid contained in a bottle or can, said device comprising a tube having an open top and for insertion in the bottle or can; a first container provided in said tube and a first heat-exchanging fluid provided in said first container; a second container provided in said tube beneath said first container and a second heat-exchanging fluid provided in said second container; connecting means fixed to said first container and slidably engaging said second container for connecting said first container to said second container; at least one tube opening provided in said tube for flowing the liquid from the bottle or can, through said tube opening and from said open top when the bottle or can is inverted; a seal provided in said second container between said first heat-exchanging fluid and said second heat-exchanging fluid to prevent commingling of said first heat-exchanging fluid and said second heat-exchanging fluid through said connecting means; and a button slidably disposed in said tube and contacting said second container for displacing said second container in said tube, contacting said seal with said connecting means, rupturing said seal and mixing said first heat-exchanging fluid with said second heat-exchanging fluid in said second container, responsive to application of pressure on said button. 2. The device of claim 1 comprising a cap provided on said tube, said cap adapted for attachment to the bottle or can and a cap opening provided in said cap, said cap opening communicating with said open top of said tube and said at least one tube opening in said tube for flowing the liquid from the bottle or can, through said at least one tube opening and said open top in said tube and through said cap opening in said cap. 3. The device of claim 2 wherein said tube is at least partially submerged in the liquid contained in the bottle or can. 4. The device of claim 3 wherein said connecting means comprises a hollow straw. 5. The device of claim 4 comprising a cap provided on said tube, said cap adapted for attachment to the bottle or can and a cap opening provided in said cap, said cap opening communicating with said open top of said tube and said at least one tube opening in said tube for flowing the liquid from the bottle, through said at least one tube opening and said open top in said tube and through said cap opening in said cap. 6. The device of claim 5 comprising a valve provided in said cap, said valve communicating with said cap opening for selectively opening and closing said cap opening. 7. The device of claim 1 wherein said tube is inserted in an opening provided in the bottom of the bottle or can. 8. The device of claim 7 comprising a cap provided on said tube, said cap adapted for attachment to the bottle and a cap opening provided in said cap, said cap opening communicating with said open top of said tube and said at least one tube opening in said tube for flowing the liquid from the bottle, through said at least one tube opening and said open top in said tube and through said cap opening in said cap. 9. A device for cooling or heating a liquid contained in a bottle, said device comprising a tube having a tube wall and an open top end terminating said tube wall, said tube sized for insertion in the bottle and at least partially submerged in the liquid; a first container provided in said tube, a first container neck downwardly-extending from said first container and a first heat-exchanging fluid provided in said first container; a second container provided in said tube beneath said first container, a second container neck upwardly-extending from said first container and slidably receiving said first container neck and a second heat-exchanging fluid provided in said second container; at least one tube opening provided in said tube wall for flowing the liquid from the bottle or can, through said tube opening and said open top of said tube when the bottle or can is inverted; a seal provided in said second container neck to prevent commingling of said first heat-exchanging fluid and said second heat-exchanging fluid; and a button slidably disposed in said tube and contacting said second container for displacing said second container upwardly in said tube, contacting said seal with said first container neck, rupturing said seal against said first container neck and mixing said first heat-exchanging fluid with said second heat-exchanging fluid in said second container, responsive to application of pressure on said button. 10. The device of claim 9 comprising a valve provided in said cap, said valve communicating with said cap opening for selectively opening and closing said cap opening. 11. The device of claim 9 comprising a straw fixedly engaging said first container neck and slidably engaging said second container neck for contacting and rupturing said seal response to said application of pressure on said button and a straw seal receiving said first container neck and said second container neck for sealing said straw. 12. The device of claim 11 comprising a cap provided on said tube, said cap adapted for attachment to the bottle and a cap opening provided in said cap, said cap opening communicating with said open top of said tube and said at least one tube opening in said tube for flowing the liquid from the bottle, through said at least one tube opening and said open top in said tube and through said cap opening in said cap. 13. The device of claim 12 comprising a valve provided in said cap, said valve communicating with said cap opening for selectively opening and closing said cap opening. 14. A device for cooling or heating a liquid contained in a bottle or can having an internal bottle sleeve, said device comprising a first container provided in said bottle sleeve and a first heat-exchanging fluid provided in said first container; a second container provided in said bottle sleeve beneath said first container and a second heat-exchanging fluid provided in said second container; connecting means fixed to said first container and slidably engaging said second container; a seal provided in said second container between said first heat-exchanging fluid and said second heat-exchanging fluid to prevent commingling of said first heat-exchanging fluid and said second heat-exchanging fluid through said connecting means; and a button slidably disposed in said bottle sleeve and contacting said second container for displacing said second container in said sleeve contacting said seal with said connecting means, rupturing said seal and mixing said first heat-exchanging fluid with said second heat-exchanging fluid in said second container, responsive to application of pressure on said button.
