Abstract
A self-cooling beverage container system. The system includes a can, and an external chamber coupled to the bottom of the can for containing compressed gas therein. Helical tubing in the form of a single or double helix resides within the can. A first open end of the tubing is disposed in communication with the external chamber, and an opposing terminal end of the tubing is closed, preferably being accessible with a pull-tab as presently known in the field for opening a vessel responsive to pulling action by a user. When the terminal end of the tubing is opened it communicates with atmosphere, permitting the compressed gas to flow from the external chamber through the tubing and into atmosphere. The gas expands as it flows, thereby withdrawing heat from the surrounding beverage in which the tubing is submerged to cool the beverage.
