A beverage container assembly comprising:

• a beverage container body including a container lower portion having a beverage cavity, a container upper portion with a container upper portion passageway in fluid communication with the beverage cavity and terminating in an upwardly opening passageway upper end, the container having an inner sidewall portion and an outer sidewall portion spaced outward of the inner sidewall portion sealed together to define a fluid-tight body insulation chamber therebetween having a sealed vacuum therein;
• a stopper having a stopper upper end portion and a stopper lower end portion, the stopper being removably insertable into the container upper portion passageway through the passageway upper end to position the stopper lower end portion below the passageway upper end and to close the container upper portion passageway, the stopper being removably engageable with the container upper portion, the interface between the container upper portion and the stopper defining a seam therebetween;
• and
• a thermal insulation member removably attachable to the container upper portion, the thermal insulation member having an upper portion and a sidewall projecting downwardly from the upper portion and terminating at a lower end, the sidewall having an inner sidewall portion and an outer sidewall portion spaced outward of the inner sidewall portion to define a thermal insulation member insulation chamber therebetween, the thermal insulation member insulation chamber extending downward from the upper portion of the thermal insulation member fully to the lower end of the sidewall, the inner sidewall portion of the sidewall of the thermal insulation member defining a downwardly opening interior chamber sized to receive therein at least a portion of the container upper portion and the stopper upper end portion extending above the passageway upper end when the thermal insulation member is attached to the container upper portion, the lower end of the sidewall of the thermal insulation member abutting the outer sidewall portion of the container when the thermal insulation member is attached to the container upper portion to define an insulated cavity between the inner sidewall portion of the sidewall of the thermal insulation member and the stopper upper end portion extending above the passageway upper end and an upper portion of the outer sidewall portion of the container extending upward above the lower end of the sidewall of the thermal insulation member, the insulated cavity containing heat from the beverage cavity conducted upward through the inner sidewall portion of the container, outward past the seam and downward through the outer sidewall portion of the container and then radiating outward from the outer sidewall portion of the container into the insulated cavity.

A beverage container assembly comprising:

• a beverage container body including a container lower portion having a beverage cavity, a container upper portion with a container upper portion passageway in fluid communication with the beverage cavity and terminating in an upwardly opening passageway upper end, the container having an inner sidewall portion and an outer sidewall portion spaced outward of the inner sidewall portion sealed together to define a fluid-tight body insulation chamber therebetween having a sealed vacuum therein;
• a stopper having a stopper upper end portion and a stopper lower end portion, the stopper being removably insertable into the container upper portion passageway through the passageway upper end to position the stopper lower end portion below the passageway upper end and to close the container upper portion passageway, the stopper being removably engageable with the container upper portion, the interface between the container upper portion and the stopper defining a seam therebetween;
• and
• a thermal insulation member removably attachable to the container upper portion, the thermal insulation member having an upper portion and an insulating sidewall projecting downwardly from the upper portion and terminating at a lower end, the sidewall of the thermal insulation member defining a downwardly opening interior chamber sized to receive therein at least a portion of the container upper portion and the stopper upper end portion extending above the passageway upper end when the thermal insulation member is attached to the container upper portion, the lower end of the sidewall of the thermal insulation member abutting the outer sidewall portion of the container when the thermal insulation member is attached to the container upper portion to define an insulated cavity between the sidewall of the thermal insulation member and the stopper upper end portion extending above the passageway upper end and an upper portion of the outer sidewall portion of the container extending upward above the lower end of the sidewall of the thermal insulation member, the insulated cavity containing heat from the beverage cavity conducted past the seam and then radiating outward into the insulated cavity.
