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.
Claims25
A beverage container comprising:
- a body having a closed bottom end and an open upper end and constructed from glass, wherein the body is formed with at least one wall, and wherein an inner surface of the at least one wall proximal the upper end is formed from ground glass to form a first half of a glass joint;
- and,
- a lid constructed from glass having a top lid surface and a bottom lid surface spaced by a lid side wall, wherein a surface of the lid side wall is formed from ground glass to form a second half of a glass joint, wherein the lid side surface registers against the inner surface of the at least one wall to form a glass joint when the lid is inserted into the upper open end of the body, wherein the lid has portions defining a drinking port or side channel that extends from the top lid surface to the bottom lid surface and other portions that define a vent port or vent channel that extends from the top lid surface to the bottom lid surface.
The beverage container of 1 wherein the lid is formed with a raised grip.
A beverage container comprising:
- a body having a closed bottom end and an open upper end and constructed from glass, wherein the body is formed as a double wall having an inner wall and an outer wall, wherein a wall gap is defined by an inner surface of the outer wall and an outer surface of the inner wall, wherein the closed bottom end is formed with an inner bottom wall and an outer bottom wall to form a double bottom wall with the inner bottom wall continuous with the inner wall and the outer bottom wall continuous with the outer wall, wherein a bottom gap defined by an inner surface of the outer bottom wall and an outer surface of the inner bottom wall is continuous with the wall gap, and wherein an inner surface of the inner wall proximal the upper end is formed from ground glass to form the first half of the glass joint;
- and,
- a lid having a top lid surface and a bottom lid surface spaced by a lid side wall, wherein the top lid surface, bottom lid surface and lid side wall define a cavity, wherein the cavity is filled with an insulating gas, wherein a drinking port or channel is formed in to lid that traverses the lid from the top lid surface to the bottom lid surface, wherein a vent port channel is formed in the lid that traverses the lid from the top lid surface to the bottom lid surface, wherein a surface of the lid side wall is formed from ground glass to form a second half of a glass joint, wherein the lid side surface registers against the inner surface of the inner wall to form a glass joint when the lid is inserted into the upper open end of the body.
A beverage container comprising:
- a body having a closed bottom end and an open upper end and constructed from glass, wherein the body is formed with at least one wall, and wherein an inner surface of the at least one wall proximal the upper end is formed from ground glass to form a first half of a glass joint;
- and,
- a lid having a top lid surface and a bottom lid surface spaced by a lid side wall, wherein the top lid surface defines a first half recess and a second half recess, wherein the first half recess is formed with a plurality of through-bores, wherein the second half recess is formed with at least one through-bore, wherein a drinking port or channel is formed in to lid that traverses the lid from the top lid surface to the bottom lid surface, wherein a vent port of channel is formed in the lid that traverses the lid from the top lid surface to the bottom lid surface, wherein a surface of the lid side wall is formed from ground glass to form a second half of a glass joint, wherein the lid side surface registers against the inner surface of the inner wall to form a glass joint when the lid is inserted into the upper open end of the body.
