ABSTRACT:
A portable, self heating, container assembly for use in a motor vehicle includes an electrically heated double-walled insulated vessel having a lower end portion telescopically, rotatably and removably received in a tubular socket of a separate base unit. The socket bottom has a pair of electrical contacts connected through a power switch and fuse to a power cord adapted to be plugged into the vehicle cigarette lighter socket. The pair of contacts are engageable with cooperating electrical contacts on the vessel bottom for energization of the heating element upon the vessel being received in the recessed in the socket. The vessel bottom and socket have cooperating spaced, interengageable radial locking flanges arranged to securely lock the vessel and base unit together upon rotation of the vessel relative to the base unit after the lower end portion of the vessel is placed in to the socket.
