Insulated beverage container

A beverage container for insulating a beverage that is served in a disposable cup, the disposable cup having a disposable cup sidewall that is sloped to narrow the disposable cup downward and a rim located radially outward with respect to the disposable cup sidewall, the beverage container comprising:

• a container body having a top end and a bottom end, the container body configured to stand on the bottom end, the container body comprising:
• a lip on the top end;
• a sidewall, the sidewall comprising an outer tubular metal sidewall and an inner tubular metal sidewall located radially inside the outer tubular metal sidewall, the sidewall having an exterior surface below the lip;
• a bottom wall, the bottom wall comprising an outer bottom metal wall and an inner bottom metal wall, the inner bottom metal wall supported by the inner tubular metal sidewall;
• a vacuum chamber located radially between the outer tubular metal sidewall and the inner tubular metal sidewall and further axially between the outer bottom metal wall and the inner bottom metal wall;
• and
• a hold formed by both of the bottom wall and the sidewall, an opening into the hold being defined by the lip, wherein the container body is configured to receive the disposable cup within the hold through the opening such that the vacuum chamber is both radially outward and axially below the disposable cup to thermally insulate the beverage within the disposable cup;
• and
• a retainer comprising an outer part and an inner part, the outer part and the inner part formed from one contiguous piece of material, the outer part configured to mount the retainer on the top end of the container body by the outer part circumferentially surrounding the exterior surface of the sidewall,
• wherein the container body and the retainer are configured to hold the disposable cup while the retainer is mounted on the top end of the container body such that the inner part of the retainer extends down through the opening to engage the disposable cup sidewall within the hold while the rim of the disposable cup is positioned above and not in contact with the container body and while the disposable cup extends down into the hold below the retainer so that the vacuum chamber thermally insulates the beverage held by the disposable cup, and
• wherein an annular part of the vacuum chamber is directly radially between the outer part of the retainer and the inner part of the retainer when the retainer is mounted on the top end of the container body and the disposable cup is held within the hold.

• and
• a cap comprising an outer part and an inner part, the outer part configured to mount the retainer on the top end of the container body by the outer part circumferentially surrounding the exterior surface,
• wherein the container body and the cap are configured to retain the disposable cup when the cap is mounted on the top end of the container body via the outer part such that the inner part of the cap extends down through the opening and into the hold and engages the disposable cup sidewall within the hold while the rim of the disposable cup is positioned above the container body and the disposable cup extends down below the cap within the hold so that the chamber thermally insulates the beverage within the disposable cup.
