Portable Pouch Heating Unit

摘要

A portable pouch for use in heating temperature sensitive materials is disclosed. The pouch includes a heating unit with one or more fasteners attached around its outer edges. The heating unit can be folded to allow the one or more fasteners to secure opposing outer edges of the heating unit together to form a pocket for substantially enclosing the materials to be warmed. The heating unit can be electrically connected to a direct current power source. The heating unit includes first and second cover layers enclosing a heat generating element and a carbon-based heat spreading element. A thermal insulation layer is also positioned between the first and the second cover layers. The heating element is adapted to generate and evenly spread heat over the interior surface of the pocket to evenly heat the materials disposed within the pocket.
