Abstract
Abstract A portable heating device for such applications as popping corn or heating liquids or infants' bottles of milk which employs a cup shaped member containing an electric heating element electrically insulated from the member which is disposed between an open relatively large round top end having an internal thread and a closed relatively small round bottom end having an external thread. An electrical connector is secured to the outside of the cup and is electrically connected to said element. A vertical cylindrically shaped sleeve open at its top end has a bottom end engaging the top end of the member. A vertically flexible hollow cylinder is disposed along side of the member and sleeve, the bottom end of the cylinder being closed, the top end being open. A hollow deflector chute extends between the sleeve and the cylinder, the chute having two spaced open ends, one chute end being connected to the top end of the cylinder, the other chute end being connected to the top end of the sleeve.
