<p>A self-cooling beverage container is disclosed. The self-cooling beverage container comprises a beverage container housing including a side wail portion, a container base and a container top having a breakable die-cut therein and a downwardly displaceable portion near said die-cut; a pull tab attached to said container top at a fastener connecting said puH tab and said container top, said pull tab having an engagement end which pushes on said downwardly dispiaceable portion of said container top to break said die-cut whenever an opposite end of said puli-tab is pulled away from said top; a coolant spiral inside said beverage container containing a coolant gas stored under pressure, said spiral having a spiral top with a breakable seal through which said coolant gas is released; a spiral support inside said beverage container connected to said beverage container holding said coolant spiral in a perpendicular position relative to the highest point of said container base; a needle inside said beverage container having a sharp end facing said breakable seal of said spiral; and if appropriate a storage gas held inside said beverage container under a pressure sufficient to elastically deform said container top outwardly in a direction away from the interior of said beverage container, whereby said container top elastically relaxes upon release of the pressure of said storage gas so that said container top moves inwardly toward the interior of said beverage container upon the release of the storage gas pressure.</p> |
