Claim 0:
1. A hollow expansion chamber, comprising:
a chamber body defined as having a top portion above a bottom portion, wherein both the top portion and the bottom portion cooperatively form a hollow chamber volume configured to temporarily contain an expansion of bubbles during an aeration process for aerating a liquid, the liquid being wine or other alcoholic beverages;
wherein the top portion and bottom portion meet to define a maximum inside diameter;
wherein, when moving circumferentially downward along the chamber body starting from the maximum inside diameter, the shape of the bottom portion has a first integral transition to a first frustoconical shape, which continuing moving circumferentially downward the first frustoconical shape has a second integral transition to a cylindrical extension, the cylindrical extension at a distal end having a bottom opening, wherein the bottom opening is configured to engage inside an opening of an uncorked and/or opened alcoholic container or bottle;
wherein the top portion has a top opening, the top portion being disposed above the opening of the uncorked and/or opened alcoholic container or bottle when the bottom opening is engaged with the opening of the uncorked and/or opened alcoholic container or bottle, wherein the hollow chamber volume is in fluid communication with surrounding air through the top opening;
wherein the hollow chamber volume is configured to be in fluid communication with an inside of the uncorked and/or opened alcoholic container or bottle when the bottom opening is engaged with the opening of the uncorked and/or opened alcoholic container or bottle;
wherein the maximum inside diameter of the hollow chamber volume in a horizontal plane is cooperatively formed between the top and bottom portions;
wherein, when the hollow expansion chamber is oriented with the top opening above the bottom opening, an entirety of an inside surface of the hollow chamber volume of the chamber body is internally sloped to drain all the liquid out through the bottom opening;
wherein the first integral transition is a tangential first integral transition between the bottom portion of the chamber body to the first frustoconical shape;
wherein the first frustoconical shape has a minimum angle of 15 degrees relative to the horizontal plane; and
wherein the second integral transition is a radial second integral transition having an inside surface radius of at least 0.25 inches.
