Heat packages and methods of their use

Abstract

The present invention provides a heat package wherein a surface of a generating heat element that generates heat when exposed to atmosphere is placed against or attached to a heat conductive member. The heat element is protected from atmosphere until use. The heat package may include a heat-generating element attached to an insulating member with one or more air spaced there between. An outer surface of the heat-generating element can be exposed to atmosphere to produce heat when desired.

1 . A heat package, comprising: 
 (a) a heat generating element; and    (b) an insulating member juxtaposed on at least a portion of a surface of the heat-generating element.
