Stopper for forming a gas-tight seal for a variety of bottles

An adjustable bottle stopper which comprises:

• a threaded disk nut having threaded interior and exterior surfaces;
• a bolt that screws into said threaded disk nut via the threaded interior surface of said threaded disk nut, the bolt and threaded disk nut thereby forming a threaded disk nut and bolt assembly;
• a lower pressure stamp nut having a threaded insertion point, wherein the threaded insertion point receives said threaded disk nut and bolt assembly, said threaded insertion point extends a distance allowing said threaded disk nut to be screwed into a position lower than said threaded insertion point, and said lower pressure stamp nut has a cavity defined therein that when combined with the threaded disk nut forms a chamber for receiving said bolt;
• a cylindrical elastic spacer centrally bored and mounted on the bolt, the elastic spacer having upper, lower, and central sections, wherein said cylindrical elastic spacer's upper and lower sections have circular ledges with smaller outside diameters than the central section of the cylindrical spacer, thereby allowing the cylindrical elastic spacer to be sleeved into the threaded insertion point of the lower pressure stamp;
• an upper pressure stamp centrally bored having interior and exterior surfaces and mounted on the bolt above the cylindrical elastic spacer, wherein the upper pressure stamp has lower and upper parts, said lower part of the upper pressure stamp indented from the interior surface toward the exterior surface, so that said cylindrical elastic spacer's upper section will be sleeved within said lower part of the upper pressure stamp;
• and
• a handle nut attached to said bolt above said upper pressure stamp.
