Abstract

A beverage container assembly is provided comprising a beverage container body, a stopper member removably attachable to the beverage container to seal a beverage container aperture thereof, and a thermal insulation member removably attachable to an upper body portion of the beverage container body. The thermal insulation member has a sidewall extending downwardly from an upper portion and defining a downwardly opening cavity within which the upper body portion and the stopper are positioned. The sidewall and the upper portion of the thermal insulation member each include an inner wall and an outer wall spaced apart from the inner wall. An insulation chamber is disposed between the inner and outer walls. The thermal insulation member includes an engagement portion adapted to engage with a corresponding engagement portion of the upper body portion to removably attach the thermal insulation member thereto.

First claim

The invention claimed is:

1. A beverage container assembly comprising:
a beverage container body including a container lower portion having a beverage cavity, a container upper portion and a container aperture positioned between the container lower portion and the container upper portion, the container upper portion having a container upper portion passageway extending upwardly from the container aperture and terminating in an upwardly opening passageway end portion, the beverage cavity extending downwardly from the container aperture, the container upper portion including a stopper member engagement portion and a thermal insulation member engagement portion, the container having an inner sidewall portion and an outer sidewall portion spaced outward of the inner sidewall portion sealed together to define a fluid-tight body insulation chamber therebetween having a sealed vacuum therein;
a stopper member having a first container engagement portion removably engageable with the stopper member engagement portion to removably attach the stopper member to the container upper portion, the stopper member being sized to fit at least partially within the container upper portion passageway to close the container upper portion passageway and thereby seal the container aperture, the interface between the container upper portion and the stopper member defining a seam therebetween; and
a thermal insulation member having a second container engagement portion removably engageable with the thermal insulation member engagement portion to removably attach the thermal insulation member to the container upper portion, an upper portion, an insulating sidewall portion projecting downwardly from the upper portion, the upper portion and the sidewall portion covering at least a portion of the stopper member located adjacent to the passageway end portion, the passageway end portion and at least a portion of the container upper portion extending downwardly from the passageway end portion when the thermal insulation member is attached to the container upper portion, a lower end portion of the sidewall portion of the thermal insulation member abutting the outer sidewall portion of the container when the thermal insulation member is attached to the container upper portion to define an insulated cavity between the thermal insulation member and a portion of the stopper member extending upward above the passageway end portion of the container upper portion and an upper portion of the outer sidewall portion of the container extending upward above the lower end portion of the sidewall portion of the thermal insulation member, the insulated cavity containing heat from the beverage cavity conducted upward through the inner sidewall portion of the container, outward past the seam and downward through the outer sidewall portion of the container and then radiating outward from the outer sidewall portion of the container into the insulated cavity.

2. The beverage container assembly of claim 1 , wherein the thermal insulation member engagement portion is located below the passageway end portion, and the second container engagement portion is located below the upper portion of the thermal insulation member.

3. The beverage container assembly of claim 2 , wherein the sidewall portion of the thermal insulation member includes an inner sidewall portion and an outer sidewall portion spaced outward of the inner sidewall portion to define a body insulation chamber therebetween, the thermal insulation member engagement portion being located on the upper portion of the outer sidewall portion of the container and the second container engagement portion being located on the inner sidewall portion of the thermal insulation member.

4. The beverage container assembly of claim 3 , wherein the container lower portion has an upper end portion, the thermal insulation member engagement portion being located closer to the upper end portion of the container lower portion than to the passageway end portion.

5. The beverage container assembly of claim 4 , wherein a portion of the upper portion of the outer sidewall portion of the container extends below the thermal insulation member engagement portion to the upper end portion of the container lower portion.

6. The beverage container assembly of claim 1 , wherein the container lower portion has an upper end portion, and the lower end portion of the sidewall portion of the thermal insulation member is spaced away from the upper portion of the thermal insulation member, and the sidewall lower end portion of the thermal insulation member is located below the second container engagement portion and adjacent to the upper end portion of the container lower portion.

7. The beverage container assembly of claim 6 , wherein the lower end portion of the sidewall portion of the thermal insulation member abuts the outer sidewall portion of the container at the upper end portion of the container lower portion when the thermal insulation member is attached to the container upper portion.

8. The beverage container assembly of claim 1 , wherein the upper portion of the thermal insulation member includes an upper portion inner wall and an upper portion outer wall upwardly spaced above the upper portion inner wall to define a first insulation chamber portion therebetween, and the sidewall portion of the thermal insulation member includes a sidewall inner wall and a sidewall outer wall peripherally spaced outward of the sidewall inner wall to define a second insulation chamber portion therebetween, the second insulation chamber extending downward from the upper portion of the thermal insulation member fully to a lower end of the lower end portion of the sidewall portion of the thermal insulation member.

9. The beverage container assembly of claim 8 , wherein the first and second insulation chamber portions define a vacuum-sealed chamber.

10. The beverage container assembly of claim 8 , wherein the first and second insulation chamber portions have an insulation material therein.

11. The beverage container assembly of claim 8 , wherein the upper portion inner wall, the upper portion outer wall, the sidewall inner wall and the sidewall outer wall are comprised of a same material.

12. The beverage container assembly of claim 1 , wherein the upper portion and the sidewall portion of the thermal insulation member define a downwardly opening cavity sized to receive at least a portion of the stopper member located adjacent to the passageway end portion, the passageway end portion and at least a portion of the container upper portion.

13. A thermal insulation member for removably attaching to a beverage container having a stopper, the beverage container having a container upper portion with a container upper portion passageway and terminating in an upwardly opening passageway upper end, the container having an inner sidewall portion and an outer sidewall portion spaced outward of the inner sidewall portion sealed together to define a fluid-tight body insulation chamber therebetween having a sealed vacuum therein, the stopper having a stopper upper end portion and a stopper lower end portion, the stopper being removably insertable into the container upper portion passageway through the passageway upper end to position the stopper lower end portion below the passageway upper end and to close the container upper portion passageway, the interface between the container upper portion and the stopper defining a seam therebetween, the thermal insulation member comprising:
a thermal insulation member removably attachable to the container upper portion, the thermal insulation member having an upper portion and a sidewall projecting dow
