ABSTRACT:
A plastic drinking container and holding stand for maintaining a heated beverage at a suitable elevated drinking temperature includes a thin metallic cup-shaped insert having a positive temperature coefficient (PTC) ceramic heater affixed to the bottom wall thereof. An electrically non-conductive plastic sleeve encapsulates the insert and ceramic heater and has a thick outer shell with a thick bottom providing good thermal insulation characteristics and a film-like inner shell permitting rapid heat transfer from the metal insert to the beverage in the container. A pair of electrical contact pins extend into a linear groove on the bottom of the container for mating with spring contacts located between a pair of linear guides at the top of the holding stand and adapted to be received in the linear container groove. An upstanding tab on the stand engages a recess in the container groove to positively restrain the container against movement when mounted on the stand.
