Claim:
A system for use with a consumable beverage, the system comprising: a container having an upper perimeter portion defining a mouth; a lid detachably engageable with the container; a collar locatable within the mouth and the upper perimeter portion of the container, the collar being positionable within the container and secured therein by the lid upon attachment of the lid to the container; a thermal energy storing member detachably engageable with the collar, the thermal energy storing member having a generally solid, continuous outer surface that defines an outer perimeter of the thermal energy storing member adapted to cause the consumable beverage to move around the outer perimeter of the thermal energy storing member until the consumable beverage is proximate to the lid; and at least one liquid passageway between an inside of the container and the mouth, wherein the thermal energy storing member is engageable with the collar via a twist lock mechanism, wherein the thermal energy storing member can be securely engaged with the collar by inserting an end of the thermal energy storing member into an opening of the collar and then laterally twisting the thermal energy storing member through a maximum arc of rotation of less than three hundred sixty (360) degrees to secure the energy storing member within the collar.
