Gas-pressurized beverage keg
First Claim
1. A beverage container comprising:
- a substantially cylindrical lower side wall and floor defining a lower beverage chamber and centered on an axis;
a substantially cylindrical upper side wall and upper wall centered on the axis and defining an upper pressurized-gas chamber axially aligned above the lower chamber;
an annular partition having an outer edge welded to an upper edge of the lower side wall and a lower edge of the upper side wall and a center part closely juxtaposed with the upper wall of the upper chamber, the partition downwardly closing the upper chamber and upwardly closing the lower chamber;
a tap assembly mounted on the upper-chamber upper wall and having a riser tube projecting through the partition center part into a lower region of the lower chamber, a gas valve fixed to the upper-chamber upper wall, and a tap valve protecting radially past the upper ring; and
a pressure regulator connected between the gas valve and the tap valve;
an upper protective ring fitted to the upper part and formed with a seat fitted to the tap valve; and
a lower protective ring fitted to the lower part, the rings and side walls having generally the same diameters.

Abstract
A beverage container has a cylindrical lower side wall and floor defining a lower beverage chamber and centered on an axis, a cylindrical upper side wall and upper wall centered on the axis and defining an upper pressurized-gas chamber, and an annular partition having an outer edge welded to an upper edge of the lower side wall and a lower edge of the upper side wall and a center part closely juxtaposed with the upper wall of the upper chamber. A tap assembly mounted on the upper-chamber upper wall has a riser tube projecting through the partition center part into a lower region of the lower chamber. An upper protective ring is fitted to the upper part and to the valve assembly and a lower protective ring is fitted to the lower part. The rings and side walls have the same diameters.
