Abstract
An insulated beverage container having both hot and cold retention capabilities designed for the purpose of maintaining, increasing, or decreasing the temperature of the contents in the container. The plastic structure of the container, an insulating sleeve between duel walls of the container, and encapsuled between the dual walls, a thermoplastic gel capable of retaining heat as well as cold, produces a multi-action container which can be heated in a microwave oven, a conventional oven, or can be frozen in a freezer. The hot-cold embodiment is available in the form of pitchers as well as cups and mugs and is also dishwasher safe. A second styrofoam embodiment of the invention structured as a can or bottle holder has inner walls containing a cold insulation medium which can be refrigerated or frozen and is designed to maintain or decrease the temperature of the contents in the held can or bottle for prolonged periods of time.
