Insulated beverage apparatus and cooling device

A device for a beverage container, comprising:

• a tubular member that is insulated and has an axis, an upper axial end and a lower axial end, both the upper and lower axial ends are open, and the tubular member is configured to receive and insulate a beverage container therein;
• a base removably coupled to the lower axial end of the tubular member to close the lower axial end, the base having an interior compartment containing a fluid permanently sealed therein, the fluid having a freezing point of about 0° C. or less, and a bottom of the base is flat, a top of the base is convex, and the top of the base is configured to contact a bottom of the beverage container;
• and
• an axial length of the tubular member is configured to be about 50% to about 100% of an axial length of the beverage container for serving a beverage from the beverage container while the beverage container is retained in the device.

A device for a beverage container, comprising:

• a tubular member that is insulated and has an axis, an upper axial end and a lower axial end, both the upper and lower axial ends are open, the tubular member is configured to receive and insulate a beverage container therein, and a thickness between an interior surface and an exterior surface of the tubular member varies, and the interior surface of the tubular member has a symmetrical parabolic sectional shape;
• a base removably coupled to the lower axial end of the tubular member to close the lower axial end, the base having an interior compartment containing a fluid permanently sealed therein, the fluid having a freezing point of about 0° C. or less;
• and
• elastomers mounted to the tubular member and the base, and the elastomer mounted to the base envelopes the base, other than a coupling extending from the base.
