Actively heated or cooled drinkware container

A container system, comprising:

• a container body that extends between a proximal end and a bottom wall at a distal end, the container body having an outer wall and an inner wall spaced inward of the outer wall to define a cavity therebetween, the inner wall extending between an opening at a proximal end of the container body and a base wall, the inner wall and base wall defining a chamber, the bottom wall spaced below the base wall;
• a phase change material disposed in the cavity and in thermal communication with at least a portion of the chamber, the phase change material spaced apart from the outer wall;
• and
• a thermal conductor housed in the cavity and configured to move between a retracted position proximate the base wall where a gap is defined between the thermal conductor and the bottom wall, and a deployed position proximate the bottom wall where the thermal conductor is in thermal communication with the bottom wall, the thermal conductor having one or more walls disposed in thermal communication with the phase change material and disposed between the phase change material and the outer wall.
