Insulated beverage container

A method of using 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, a bottom end, an outer tubular sidewall, an inner tubular sidewall located radially inside the outer tubular sidewall, an outer bottom wall, an inner bottom wall that is supported by the inner tubular sidewall, an insulation chamber located radially between the outer tubular sidewall and the inner tubular sidewall and axially between the outer bottom wall and the inner bottom wall, and a hold formed by both of the inner tubular sidewall and the inner bottom wall, the beverage container further comprising a retainer configured to mount on the top end of the container body, the method comprising:

• insulating the beverage within the disposable cup with the insulation chamber by the disposable cup being within the hold while the retainer, mounted on the top end of the container body, extends downward into the hold of the container body to contact the sidewall of the disposable cup;
• and
• flowing the beverage from inside the disposable cup to outside of the disposable cup for drinking while the disposable cup is retained within the hold by the retainer.

A method of using 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, a bottom end, a hold, and a vacuum chamber located radially directly outward from the hold and axially directly below the hold, the beverage container further comprising a body configured to mount on the top end of the container body to retain the disposable cup, the body comprising an outer ring and an inner part, the method comprising:

• mounting the body on the top end of the container body so that the outer ring of the body circumferentially surrounds the top end of the container body;
• insulating the beverage in the disposable cup with the vacuum chamber by the disposable cup being within the hold while the inner part of the body extends downward into the hold of the container body to contact the sidewall of the disposable cup so that part of the vacuum chamber is directly radially between the inner part and the outer ring of the body;
• and
• flowing the beverage from inside the disposable cup to outside of the disposable cup for drinking while the disposable cup is retained within the hold by the body,
• wherein the disposable cup extends out of the hold and beyond the container body during both of insulating the beverage and flowing the beverage.
