Abstract
A beverage container for hot or cold beverages, where the lid and base are connected via a glass joint. The glass joint forms a seal between the lid and base and eliminates the need for a synthetic material to form such a seal. The base has a double wall construction forming a cavity between the two walls. One or more of the surfaces facing the cavity are coated with a thermally reflective coating, which along with the glass materials, reduces heat transfer to the external surroundings. The lid is formed by a glass shell with an internal cavity, where the internal surfaces defining the cavity are optionally coated with a thermally reflective coating to further insulate the beverage container.
