The present invention is directed to a portable and microwaveable container into which a vessel may be inserted, and which assists in preserving or prolonging elevated temperatures of the contents of the vessel for an extended period of time. The container includes a receptacle area, or opening, into which the vessel is inserted. The container of the present invention may be heated, such as in a microwave oven, and once heated, a vessel containing a warmed food product, typically an elevated temperature liquid, may be inserted. The container of the present invention internally contains a microwaveable absorbing material which retains thermal energy. Once heated, the container passively improves the heat retention of the contents of the inserted vessel.

1. A heat retaining device comprising: a biodegradable enclosure member having a cylindrical shape with an external cavity along the side thereof so that a handle of a mug can protrude therefrom, thus an overhead view of the container is a C-shape with the opening of the C being the external cavity and a thickness of the C near the opening of the C being less than a thickness of the C distal from the opening of the C, including an exterior and an internal side chamber forming the C-shape of the enclosure; a base, including an internal base chamber, and a quantity of granular heat retention material within said internal side chamber and said internal base chamber, said heat retention material being capable of being heated by thermal energy radiation and of retaining heat in a latent state. 2. The device of claim 1, wherein said exterior is transparent to microwave radiation. 3. The device of claim 1, wherein said exterior is a paper product and the quantity granular heat retentive material is natural grains and/or seeds. 4. The device of claim 1, wherein the density of the material in said internal base chamber is greater than the density of the material in said internal side chamber. 5. The device of claim 1, wherein said heat retentive material comprises at least one food grade substance. 6. The device of claim 5, wherein said food grade substance comprises wheat berries. 7. A microwaveable heat retentive container comprising at least one receiving portion for receiving a vessel, an external shell transparent to microwave radiation having a C-shaped top profile, a handle rotatably coupled to the external shell, an internal heat storage mass comprising a first microwave absorbing material; and a base portion comprising a second microwave absorbing material; wherein said first microwave absorbing material and said second microwave absorbing material comprises at least one biodegradable food product of natural grains and/or seeds. 8. The device of claim 7, wherein said exterior shell is transparent to microwave radiation. 9. The device of claim7, wherein said exterior shell is formed at least in part of a paper product. 10. The device of claim 7, wherein the density of said second microwave absorbing material is greater than the density of said first microwave absorbing material. 11. The device of claim 7, further comprising a lid selectably coupleable to a depressed area on a top rear of the container by a clip; wherein the lid includes a hole disposed through a top to permit steam to escape. 12. The device of claim 11, wherein said microwave absorbing material comprises wheat berries; and wherein the lid includes an extension extending outwardly therefrom that allows the lid to flip up by leverage of a user pressing on the top of the lid extension.
