Abstract: A sleeve or a wrapper is used to keep liquid contained in a container, such as a glass or bottle or can, cool. The sleeve contains materials that generate light when activated and chemicals that absorb heat when combined. The light is generated in an upper portion of the sleeve while heat is absorbed in a lower portion of the sleeve. The sleeve can be re-used by storing the sleeve in a refrigerator or freezer after the initial use which does not require such pre-cooling.
