Pressure relief system for inductively heated heat retentive server
First Claim
1. A heat retentive server adapted to be inductively heated comprising:
- a central portion for holding a plate containing food;
an enclosure defining an interior region and an exterior region;
a heat storage member disposed within said interior region, said heat storage member comprising a material which is susceptible to being heated by induction; and
a valve capable of opening in response to an increase in pressure in said interior region relative to pressure in said exterior region to allow fluid communication between said interior region and said exterior region.

Abstract
A heat retentive server, comprising a central portion comprising a heat storage member formed of a material which is preferably susceptible to being heated by induction, is provided with one or more valves which are normally in closed positions, and are capable of opening to vent excess pressure in the central portion. In one preferred embodiment, a valve is placed so as to allow communication between the central portion and a different interior region of the server. In another embodiment, a valve is placed so as to allow communication between the central portion and the exterior of the server. In another embodiment, a server is provided with at least one valve of each type.
