Portable heating apparatus with temperature-retaining component

1. A portable heating apparatus, comprising:

a top layer;

a bottom layer connected to the top layer to form a cavity;

an electric heating element disposed within the cavity;

a temperature-retaining layer disposed within the cavity adjacent to the electric heating element and adjacent to the top layer and including a temperature-retaining gel therein, wherein the temperature-retaining layer is divided into a plurality of separate segments which prevent flow of the temperature-retaining gel between the plurality of separate segments; and

a power cord in electrical communication with the electric heating element and connectable to a power source to provide power to the electric heating element, the power cord detachable from the portable heating apparatus;

wherein the temperature-retaining layer retains heat generated by the electric heating element and creates a generally uniform distribution of heat across the top layer.

2. The portable heating apparatus of claim 1 , wherein the electric heating element includes a heating wire constructed from a positive temperature coefficient (PTC) material with negative temperature coefficient (NTC) insulation.

3. The portable heating apparatus of claim 1 , further comprising a padding material disposed within the cavity between the electric heating element and the bottom layer.

4. The portable heating apparatus of claim 3 , wherein the padding material includes a non-woven scrim material layer and a batting material layer.

5. The portable heating apparatus of claim 1 , wherein the top layer and the bottom layer are constructed from a micromink material.

6. The portable heating apparatus of claim 1 , wherein a portion of the top layer is removable to expose the temperature-retaining layer to an exterior of the portable heating apparatus.

7. The portable heating apparatus of claim 1 , further comprising a controller in electrical communication with the electric heating element for regulating power to the electric heating element.

8. The portable heating apparatus of claim 7 , wherein the controller includes an audible indicator that emits different tones depending on a heat level of the electric heating element.

9. A portable heating apparatus, comprising:

a top layer;

a bottom layer connected to the top layer to form a cavity;

an electric heating element disposed within the cavity;

a padding material disposed within the cavity between the electric heating element and the bottom layer;

a gel layer affixed within the cavity between the electric heating element and the top layer and including a temperature-retaining gel therein, wherein the gel layer is divided into a plurality of separate segments which prevent flow of the temperature-retaining gel between the plurality of separate segments; and

a power cord in electrical communication with the electric heating element and connectable to a power source to provide power to the electric heating element, the power cord detachable from the portable heating apparatus;

wherein the gel layer retains heat generated by the electric heating element and creates a generally uniform distribution of heat across the top layer, and the gel layer maintains a cold temperature generated by chilling the portable heating apparatus.

10. The portable heating apparatus of claim 9 , wherein a portion of the top layer is removable to expose the gel layer to an exterior of the portable heating apparatus.

11. A portable heating apparatus, comprising:

a main body including an outer, top layer and an inner, bottom layer connected to the top layer, the top and bottom layers forming a cavity therebetween;

a first strap and a second strap extending from the main body;

an electric heating element disposed within the cavity;

a temperature-retaining layer disposed within the cavity adjacent to the electric heating element and adjacent to the bottom layer and including a temperature-retaining gel therein, wherein the temperature-retaining layer is divided into a plurality of separate segments which prevent flow of the temperature-retaining gel between the plurality of separate segments; and

a power cord in electrical communication with the electric heating element and connectable to a power source to provide power to the electric heating element, the power cord detachable from the portable heating apparatus;

wherein the temperature-retaining layer retains heat generated by the electric heating element and creates a generally uniform distribution of heat across the bottom layer.

12. The portable heating apparatus of claim 11 , wherein the main body has an elongated configuration with two eye portions each sized to cover an eye of a user and an indentation therebetween sized to accommodate a nose of the user.

13. The portable heating apparatus of claim 11 , wherein at least one of the first strap and the second strap is constructed from an elastic material, and wherein the first and second straps each have a releasable closure.

14. The portable heating apparatus of claim 11 , further comprising a power adapter port provided on the bottom layer of the main body.

15. The portable heating apparatus of claim 11 , further comprising a controller in electrical communication with the electric heating element for regulating power to the electric heating element, wherein the controller includes an audible indicator that emits different tones depending on a heat level of the electric heating element.
