Beverage cooling device and method for using same
BACKGROUND OF THE INVENTION 
     This invention relates to a beverage cooling device and a method for using the same. Many beverages are sold in containers at the grocery store. Often these containers are uncooled, and therefore it is necessary for the consumer to cool the container and the beverage therein before serving it. 
     The conventional way of cooling such beverages is to place them in a refrigerator until they have been sufficiently cooled for serving. However, this takes a considerable length of time. 
     Therefore, a primary object of the present invention is the provision of an improved beverage cooling device and method for using same. 
     A further object of the present invention is the provision of a beverage cooling device which will cool the beverage in less time than prior beverage cooling devices. 
     A further object of the present invention is the provision of a beverage cooling device which is simple in construction and which operates reliably. 
     A further object of the present invention is the provision of a beverage cooling device which can cool the beverages one container at a time. 
     A further object of the present invention is the provision of a beverage cooling device which places the beverage container in contact with ice and which rotates the beverage container so as to maximize the heat exchange between the ice and the beverage. 
     A further object of the present invention is the provision of a beverage cooling device which utilizes ice, and which adjusts its position relative to the ice throughout the melting of the ice. 
     A further object of the present invention is the provision of a beverage cooling device which can be attached to beverage containers of various shapes and sizes. 
     A further object of the present invention is the provision of a beverage cooling device which is simple to attach to a beverage container and which can be easily removed from the beverage container. 
     A further object of the present invention is the provision of a device which is economical to manufacture, durable in use and efficient in operation. 
     SUMMARY OF THE INVENTION 
     The present invention utilizes an ice receptable which includes side walls, a bottom wall, and an open upper end. One wall of the ice receptacle includes an elongated vertical slot therein and also includes a vertical track mounted on the outer surface thereof. 
     A power pack includes an electric motor which may be either AC or DC and which includes an output shaft adapted to rotate in response to the actuation of the motor. The power pack includes track following members thereon which are adapted to fit within the track on the outer surface of the receptacle walls. 
     The power pack is mounted in the track for sliding movement vertically therein, with the output shaft of the motor extending through the elongated slot and into the interior of the receptacle. 
     A rubber suction cup is attached to the output shaft and is adapted to be detachably mounted to the end wall of a cylindrical beverage container. Actuation of the power pack cause the cylindrical beverage container to rotate at the same speed as the output shaft. 
     In operation, the receptacle is filled approximately two-thirds full with ice which is either in cubes or crushed. 
     The power pack is then attached to the beverage container be means of the suction cup. The beverage container and the power pack are then fitted into the elongated track on the exterior of the receptacle wall. The beverage container is within the receptacle and rests upon the ice in the receptacle. The power pack is outside the receptacle, and the output shaft of the power pack extends through the slot into the receptacle where it is attached to the beverage container. 
     The power pack is actuated which causes the beverage container to rotate or spin in frictional engagement with the ice. This spinning action causes a maximization of the heat transfer between the ice and the beverage container. The track allows the power pack to lower in response to the melting of the ice, and at the same time, keeps the beverage container and the power pack level in a straight line with each other. 
     The device will work satisfactorily with cans or bottles or other types of cylindrical containers.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT 
     Referring to the drawings, the numeral 10 generally designates the cooling device of the present invention. Device 10 includes an ice receptacle 12 and a power pack assembly 14. Receptacle 12 includes a pair of side walls 16, 18, end walls 20, 22 and a bottom wall 24. Walls 16-22 form an open end 26 at their upper edges. 
     End wall 20 is provided with an elongated vertical slot 28. Also mounted on the exterior surface of end wall 20 are a pair of track members 30, 32, each of which are U-shaped in cross-section and include a web 34 and two U-legs 36, 38 (FIG. 5). A stop flange 40 is provided adjacent the lower end of each of the track members 30, 32. 
     Power pack 14 comprises a power pack housing 42 which contains an electric motor and reduction gears (not shown) for rotating an output shaft 44. The motor within housing 42 may be either a DC motor or an AC motor as preferred. An actuation switch 46 is provided on the exterior of housing 42 for actuating and deactuating the electric motor therein. 
     Mounted on the end of shaft 44 is a suction cup 48. Also mounted on housing 42 are a pair of ribs 50 which function as track followers and which are adapted to ride within the U-shaped track members 30, 32. 
     In operation the beverage container 52 is mounted to power pack 14 by means of suction cup 48 which preferably engages the container 52 at its end wall, with output shaft 44 being aligned with the cylindrical axis of beverage container 52. Thus actuation of power pack 14 causes rotation of shaft 44 and correspondingly causes rotation of beverage container 52 about its longitudinal cylindrical axis. 
     Receptacle 12 is filled approximately two-thirds full with crushed ice or with ice cubes. Then the ribs 50 are fitted within the tracks 30, 32 so as to mount the power pack 14 and the container 12 in the position shown in FIGS. 1 and 6. In this position, the output shaft 44 is in registered alignment with slot 28 of receptacle 12 so that it can move freely vertically upwardly and downwardly therein. The beverage container 52 is resting upon the ice within receptacle 12. 
     After the power pack has been placed in the tracks 30, 32, the power pack is then actuated to cause rotation of the beverage container 52. The vertical tracks 30, 32 hold the power pack housing 42 against rotational movement, thereby causing the beverage container 52 to be rotated or spun about its longitudinal axis. This causes frictional sliding movement between the ice 54 and the beverage container 52, thereby maximizing the heat exchange between the two and causing cooling of the beverage within the container 52. 
     As the ice melts, the weight of the power pack 42 and the beverage container 52 cause downward movement of the power pack housing within the tracks 30, 32 from the position shown in FIG. 6 to the position shown in FIG. 7. This ability to move downwardly permits the beverage container 52 to stay in frictional engagement with the ice 54, thereby insuring full transfer of heat from the beverage container to the ice. 
     The present invention has been found capable of chilling canned beverages from room temperature to approximately 50° F. in one to three minutes. The device also is capable of being attached to a bottle or other cylindrical container for cooling the beverage therein. The device is simple in construction and efficient in operation. 
     Thus, it can be seen that the device accomplishes at least all of its stated objectives.
