[0003]

[Issues to be solved by the invention]

 In such a portable cooling device, there is a further demand for reliable cooling and improvement in structure of the beverage can contained in the device.

An object of the present invention is to provide a new and improved portable cooling device for cooling beverage cans.

[0005]

[Means for Solving the Problems]

 According to the present invention, there is provided a portable cooling device for cooling a beverage can, the container having an open top for storing ice cubes and a beverage can, and the open top of the container being closed to prevent from the atmosphere. A thermally insulating, closure lid for maintaining the ice cubes and the beverage can in the container, and extending into the container and coupled to the end of the beverage can for rotating the beverage can A portable cooling device having an electric motor mounted on the outside of the container having a rotatable drive shaft of the container, wherein the container restrains the beverage can against excessive lateral movement in the container and A portable cooling device is provided which comprises opposed inward ribs projecting inwardly of the container with retention of the ice cubes for longitudinal movement of the ice cubes.

The electric motor is expediently driven by the battery, and the drive shaft extending into the interior of the container through a slot extending substantially vertically at the open top of the container at one end to the one end of the container on the guide means outside the container. It consists of a self-contained motor and battery unit that can be removably attached to the.

Other features of the invention will be apparent from the following description, which is presented in the present application by way of example only with reference to the accompanying drawings.

[0008]

[Embodiment of the invention]

 As shown in the drawings, a portable cooling device constructed in accordance with the present invention has an open top and is of a length, width and depth sufficient to accommodate a beverage can 12 and ice cubes 14. It consists of a rectangular container 10. The container is conveniently molded from plastics material and can have typical overall dimensions of 245 mm x 125 mm x 115 mm. The thickness of the vessel wall is sufficient to provide thermal insulation to the can 12 and ice cubes 14 contained within the vessel. There is also a closure lid 16 which is molded from the same plastic material as the container and can be transparent, opaque or translucent. When in place, the closure lid 16 provides complete thermal insulation to the contents of the container 10 and may otherwise fall out of the container 10 if ice cubes are placed on top of the can 12. Yes, providing protection and retention of ice cubes if they could otherwise fall from the container 10.

One end wall 18 of container 10 is provided with a generally vertically extending slot 20 and an external facing groove 22 which provide a guide means for mounting a self contained motor and battery unit. The unit comprises a main body 24 for accommodating the electric motor, a battery compartment chamber 26 for accommodating the battery for driving the electric motor, and a removable battery compartment chamber cover 27 for allowing the insertion and removal of the battery. An on-off switch 28 is provided on the upper surface of the battery partition chamber 26. The end surface 30 of the unit includes a pair of opposed, outwardly extending flanges 32 shaped and dimensioned for slidable reception within opposed grooves 22 of the end wall 18 of the container 10. A rotatable drive shaft 34 extends from the end face 30 of the unit to extend through the slot 20 in its end wall 18 and into the interior of the container 10. The outer end of the drive shaft 34 is provided with a suction cup 36 for attachment to one end of the beverage can 12 in the container. Operation of the electric motor in turn causes rotation of the drive shaft 34 which causes rotation of the can 12 in the container 10 about the longitudinal axis of the can.

The container 10 includes a pair of opposed vertically extending ribs 38 therein which restrain the carousel 12 from excessive lateral movement and also ice cubes 14 against excessive longitudinal movement. Is being held.

In use, the container 10 is first wrapped with a layer of ice cubes 14 between the end wall 18 and the opposing ribs 38, the ice cubes being held in place by said ribs. Conveniently, the battery and motor unit are removed from the container and the can 12 to be cooled is attached at one end to the suction cup 36 at the outer end of the drive shaft 34. When supporting the can and unit, the can and unit are directed toward the open top of the container 10 so as to slidably mount the unit on the guide means 22 and position the can 12 on the layer of ice cubes 14. Can be lowered downwards. The closure lid 16 is then positioned on the container 10 and the motor is operated to rotate the can within the container. During rotation of such a can, ice cubes are held against excessive movement by the ribs 38 and by the lid 16. In use, the beverage can can be cooled from about 20 ° C ambient temperature to about 5 ° C in about 60 seconds.

[0012]

[Effect of the invention]

 As described above, the present invention is a portable cooling device for cooling a beverage can, which has an open top container for storing ice cubes and a beverage can, and an open top part of the container. A closure lid for maintaining the ice cubes and the beverage can in the container thermally insulated from the atmosphere, and extending into the container and coupled to the end of the beverage can, A portable cooling device comprising an electric motor mounted on the outside of the container having a rotatable drive shaft for rotation, wherein the container suppresses the beverage can against excessive lateral movement within the container; A new and improved portable device with high cooling efficiency is provided because it is provided with opposing inward ribs protruding inward of the container that holds the ice cubes against excessive longitudinal movement within the container. Providing a cooling system It can be.
