Beverage container heating apparatuses and associated methods

A flexible band configured to wrap around an exterior surface of a beverage container, the flexible band comprising:

• a first layer configured to be positioned in contact with the exterior surface of the beverage container, wherein the first layer comprises a reflective surface facing the beverage container and a heating element configured to provide heat to the exterior surface of the beverage container;
• a second layer adjacent to and covering at least a portion of the first layer, wherein the second layer comprises a removable insulation assembly;
• and
• a third layer adjacent to and covering at least a portion of the second layer, wherein the third layer comprises a gripping mechanism including one or more finger sleeves positioned to receive finger(s) of a user when the flexible band is wrapped around the beverage container.

A flexible sleeve configured to be removably attached to an exterior surface of a beverage container, the flexible sleeve comprising:

• an inner layer configured to be positioned in contact with an exterior surface of the beverage container, wherein the inner layer comprises a reflective surface facing the beverage container;
• and
• an outer layer adjacent to and covering at least a portion of the inner layer, wherein the outer layer comprises—
• a battery;
• control circuitry electrically coupled to the heating element;
• and
• a gripping mechanism,
• wherein the gripping mechanism includes a plurality of projections extending away from the outer layer, the individual projections being sized and shaped to receive at least a portion of a user's hand when the flexible sleeve is engaged with the beverage container.
