Patent ID: 8106336

Claim:
A substantially rectangular flexible food warming mat of low profile with a top surface and a bottom surface comprising: a) a layered elastomeric polymer outer surface; and, b) a series of panels, each logically divided from the next by a transverse folding line; and, c) a plurality of transverse, alternating channels conjoining said panels, said channels having a substantially ‘U’ shaped profile with an arcuate trough, wherein every other is open either to the top or bottom surface of said mat such that mat may be accordion folded upon itself, and, d) a plurality of resistive heating element embedments, one per each of said panels; and, e) a plurality of flexible connectors embedded over arcuate troughs connecting said heating element embedments in series; and, f) a power cable connected to said heating element embedments at one end with an electrical plug for use with an electrical outlet providing 110-120 VAC; and, g) a temperature controlling means with low, medium and high setting residing inline of said power cable between said electrical plug and said plurality of resistive heating element embedments.
