Abstract:
1. An apparatus for maintaining carbonation of a beverage, the apparatus comprising: a rigid enclosure having a body with an external threaded section having multiple starting threads; a threaded base cap with an internal threaded region extending the entire depth of the cap, removably coupled with the body of the rigid enclosure via a section of external threads at the lower edge of the of the body of the rigid enclosure, with the height of the base cap and the threads contained therein of sufficient length to allow the rigid enclosure to fit a range of beverage bottles of varying heights; and a concave booster with a hollow cylindrical body, open at one end and closed at the other end that fits removably within the threaded base cap in two possible orientations, either concave-up or concave-down, to accommodate beverage bottles of varying heights by adjusting the effective length of the rigid enclosure, thereby accommodating the beverage bottles of varying heights; the threaded base cap with the concave booster providing the height adjustment required to accommodate variation in bottle heights while minimizing the degree in which the threaded base cap visually obscures the beverage bottle label.
