Patent Images
1. A container for maintaining a liquid beverage in a heated state by means of electrical energy supplied thereto comprising:
- the container having an open proximal end and a closed distal end connected by a continuous side wall, the container side wall having a diameter at the distal end greater than the diameter of the proximal end to provide an enlarged capacity of the container at the distal end with respect to the proximal end, the distal end of the container having a bottom surface and a reentrant bottom cup lip, the bottom cup lip being defined by a downwardly depending bottom ring indented from the side wall of the container,a base cap positioned in juxtaposition to the distal end of the container, the base cap having a power input receptacle located in a wall thereof for receiving electrical energy,a heating element for maintaining the liquid in the container in a heated state, the heating element being electrically connected to the power input receptacle to receive electric power therefrom, the heating element further being placed adjacent to the bottom surface of the container for imparting heat directly to the bottom surface thereof,a visual indicating means electrically connected to the power input receptacle for indicating a power-on condition, the indicating means being located in the base cap and observable from the exterior thereof,the base cap being configured to fit about the bottom rim and positioned to overlie and contact the cup lip,the base cap having a proximal end and a distal end, the proximal end of the base cap being defined by an annular rim, gasket means positioned on the annular rim between the lip and the bottom cup lip, the proximal end of the base cap being placed in juxtaposition with the distal end of the container and adjacent to the cup lip,heating element support means positioned adjacent to the heating element for maintaining the heating element in juxtaposition to the bottom surface of the container,the bottom rim being provided with interrupted areas therethrough to provide mounting access for the power input receptacle and wiring for the visual indicating means therein, the bottom rim further having an inwardly facing wall, said wall being provided with a pair of diametrically spaced apart support members, each support member being provided with frictional engagement slot means for receiving the heating element mounting means,the element support means being received in frictional engagement with the bottom rim slot means to maintain the heating element adjacent to the bottom surface of the container,the bottom rim integrally formed with the bottom cup lip, the bottom cup lip terminating at the juncture of the bottom rim with the bottom surface of the container,cooperating means on said container and base cap for maintaining the base cap in juxtaposition with said container with said gasket interposed between the annular rim of the base cap and the cup lip of the container, andmeans affixed to the distal end of the base cap to provide a non-slip surface thereon.

Abstract
A portable container for maintaining a liquid in a heated state by means of electrical energy supplied to a heating element secured to the bottom of the container by a support bar having its ends frictionally inserted into support slots on the container bottom and enclosed by a base cap separable from container itself so that access may be had to the heating means. Within the separable base cap is the power connection for the container and an indicating light to show a power-on condition. The bottom of the container has an indented annular lip which cooperates with the base cap to form a continuous watertight outside wall for the complete container. The bottom cap of the container is provided with a non-skid material to assist in maintaining the container in a stationary position within a moving vehicle.
