A wide variety of techniques have been employed to keep beverages as close to the optimum consuming temperature as possible for as long as possible. For example, ice buckets have been used to chill wine, and foam and/or fabric insulation devices, e.g., koozies, have been employed to insulate beverages in cans or bottles. Prior techniques suffer from a variety of drawbacks, e.g., spilling, slipping, poor thermal performance characteristics, difficulty of use, etc. Accordingly, one object of this disclosure is to provide a simple, effective technique for neatly maintaining temperature of a beverage in a container.
