Abstract

In a portable container system for heating a beverage generally, the system includes a container for containing a beverage to be heated. The container generally has a bottom and a side wall together defining an internal reservoir containing the beverage to be heated. A base of the system is operable to heat the container at the bottom thereof. The base is constructed of multiple layers generally including at least a top barrier layer, an electrically non-conductive bottom barrier layer and a thin film heating element intermediate the top barrier layer and the bottom barrier layer.

First claim

What is claimed is:

1. A portable container system for heating a beverage, the portable container system comprising:
a container for containing a beverage to be heated, the container comprising a bottom and a side wall together defining an internal reservoir for containing the beverage to be heated, the container further comprising an elongate spout extending from the side wall and open to the internal reservoir for dispensing beverage from the container through the spout, the spout being constructed of multiple layers including a generally tubular inner barrier layer defining a conduit through which beverage from the container flows through the spout, a generally tubular outer barrier layer, and a thin film heating element disposed intermediate the inner barrier layer and the outer barrier layer.

2. The portable container system set forth in claim 1 wherein the side wall comprises an inner side wall, the container further comprising an outer side wall spaced surrounding the inner side wall in spaced relationship therewith to define a housing therebetween, the system further comprising a power source disposed with the housing an electrically connected to the thin film heating element.

3. The portable container system set forth in claim 2 further comprising a controller disposed with the housing for controlling operation of the thin film heating element.

4. The portable container system set forth in claim 1 wherein the thin film heating element comprises a substrate and an electrically conductive thin film layer, the electrically conductive thin film layer being intermediate the substrate and the outer barrier layer.
