ABSTRACT:
A nestable heated bowl comprises an outer wall, an inner wall and a bottom wall integrally connected to one another, for example, by molding plastic. The inner wall defines a cavity for receiving material such as water or food. The bottom edge of the outer wall defines an open lower end of the bowl. The bottom wall is spaced upwardly from the plane of the bottom edge of the outer wall. The inner wall and outer wall taper upwardly to define a space and are joined together to define a bowl edge. The inner wall, outer wall, and bowl edge of a second bowl are adapted to be received in said space in a compact, interengaging stackable fashion. An electric heating element, thermostat and cord are carried on underside of the bottom wall. When the bowl is inverted, the cord is windable around the thermostat adjacent to the heating element so as not to interfere with the interengaging nesting of a second bowl with the first bowl during shipment.
