Refrigerating apparatus and method

A rapid refrigeration apparatus comprising:

• a container means having liquid container contents;
• a receptacle means enclosed within said container means, said receptacle means comprising a flexible receptacle wall and containing a refrigerant;
• refrigerant release means for releasing said refrigerant into the atmosphere;
• said release means comprising a release means activation means for voluntarily opening said release means at a selected moment in time. receptacle wall such that said refrigerant in its liquid phase must pass through an extended path before exiting from said receptacle through said refrigerant release means, thereby providing fuller evaporation of said refrigerant for enhanced cooling of said container contents.

A rapid refrigeration apparatus comprising:

• a container means having container contents;
• a receptacle means enclosed within said container means, said receptacle means comprising a flexible receptacle wall and containing a liquid refrigerant;
• refrigerant release means for releasing said refrigerant into the atmosphere;
• said release means comprising a release means activation means for voluntarily opening said release means at a selected moment in time,
• such that operation of said activation means opens an aperture on the surface of said container means enabling fluid communication between said receptacle means and the atmosphere, causing a gradual evaporation and release of said refrigerant into the atmosphere and thereby lowering the temperature of the liquid refrigerant remaining in said receptacle means and causing the pressure of the evaporated gaseous refrigerant above said liquid refrigerant to decrease and collapse the flexible receptacle means and drawing heat from said container contents into said receptacle means, said heat subsequently causing the pressure of said gaseous refrigerant in said receptacle means to increase and expand the flexible receptacle wall, in a repeating cycle of flexible wall expansions and contractions thereby stirring said container contents for more rapid and efficient container contents cooling.

A rapid refrigeration apparatus comprising:

• a container means;
• a receptacle means having a variable volume and being enclosed within said container means defining a variable first volume within said receptacle means and a variable second volume between said receptacle means and said container means, one of said variable first volume and said variable second volume containing a refrigerant and the other of said variable first volume and said variable second volume containing a beverage, such that said receptacle means expands within said container until pressure equilibrium is reached between said refrigerant and said beverage;
• refrigerant release means for releasing said refrigerant into the atmosphere;
• said release means comprising release means activation means for voluntarily opening said release means at a selected moment in time.

A method of rapid refrigeration comprising the steps of:

• enclosing a refrigerant receptacle means having a flexible receptacle wall within a container means;
• placing liquid refrigerant into said receptacle means;
• placing container contents into said container means;
• opening an aperture means in said container means to open fluid communication between said receptacle means and the atmosphere, thereby causing said liquid refrigerant to gradually escape through said aperture means and draw heat from said contents of said container means;
• oscillating said flexible receptacle wall inwardly and outwardly subsequent to opening said aperture means and during said refrigerant evaporation to stir said contents of said container means for more rapid and efficient cooling of said contents of said container means.

A rapid refrigeration apparatus comprising:

• a container means having container contents;
• a receptacle means enclosed within said container means, said receptacle means comprising a telescoping vessel having variable surface area and containing a refrigerant and having a variable volume such that said receptacle means expands within and against said container contents until pressure equilibrium is reached with said container contents;
• refrigerant release means for releasing said refrigerant into the atmosphere;
• said release means comprising release means activation means for voluntarily opening said release means at a selected moment in time,
• means for expanding and reducing the volume of said receptacle means and thereby expanding and reducing said receptacle means surface area to stir said container contents for more rapid and efficient cooling of said container contents.
