Bottle with dual interlocking cups and modular base assembly

A vacuum-insulated beverage container has a body and a vacuum-insulated liner enclosed by the body. Seals between the body and the liner prevent all types of leaks of the beverage held in the liner. A handle is attached to the container in a manner that the handle is removable and is only attached with one removable fastener. Nesting drinking cups are provided that removably attach to the container and to one another. The drinking cups can be separated from one another by directly pulling the cups apart or by rotating one cup relative to another.
