Abstract
A delivery apparatus comprising a container and a heater is provided for holding an article in thermally conductive contact with the heater. The heater includes a heating grid constructed to provide a output watt density of greater than 2.5 watts per square inch. A heat sink is provided in thermally conductive contact with the heating grid for receiving and storing heat energy from the heating grid. The heater also includes a cover and a power cord. In another embodiment a delivery apparatus includes a controller. The controller provides information to the user about the status of the delivery apparatus by changing the state of a light source.
