A closure device for a beverage container comprising:

• a cylindrical body with a closed end and an open end, the cylindrical body forming a bottom edge that extends entirely along a single plane;
• a central protrusion extending radially outwardly from the bottom edge of the cylindrical body;
• a first hinge-connecting area and a second hinge-connecting area flanking the central protrusion on either side thereof;
• a first pocket formed in an interior wall of the cylindrical body defining an inner surface of the first hinge-connecting area;
• a second pocket formed in the interior wall of the cylindrical body defining an inner surface of the second hinge-connecting area;
• a first hinge extending downwardly from the first hinge-connecting area, the first hinge positioned at or below the single plane of the bottom edge of the cylindrical body, the first hinge comprising a first groove formed on an outwardly facing surface thereof at or below the single plane of the bottom edge;
• a second hinge extending downwardly from the second hinge-connecting area, the second hinge positioned at or below the single plane of the bottom edge of the cylindrical body, the second hinge comprising a second groove formed on an outwardly facing surface thereof at or below the single plane of the bottom edge;
• a first leash connected to a bottom of the first hinge at a first end and to a tamper band at a second end;
• and
• a second leash connected to a bottom of the second hinge at a first end and to the tamper band at a second end,
• wherein the first and second leashes are positioned entirely below the single plane,
• wherein a length of the first and second leashes extends along a circumference of the closure device, and
• wherein the tamper band is further connected to the bottom edge of the cylindrical body via frangible connections.
