Abstract: An improved temperature control device for maintaining the temperature of the contents of a beverage receptacle. The device is designed to keep a contained two-liter bottle cold for long periods of time. The device includes an annular column formed from insulating material encased within a durable sheath. The annular column defines a cylindrical container for placement of the two-liter bottle. A cover is included enclosing the two-liter bottle within the container. The cover is also formed from an insulating material and enclosed within a durable sheath. An outer wrap surrounds the cover and container, hingedly attaching the cover to the container so that the cover is removably securable. The outer wrap additionally includes a zipper, enabling the nylon wrap to be opened or closed, fastening the cover to the cylindrical container. The device also includes a variety of carrying straps that are removable from the outer wrap for ease and convenience.
