With respect to the illumination, a mark, logo or other symbol is visible exteriorly of the container and this logo, mark or other symbol is formed from a chemical luminescence material which, upon activation, luminesceses or glows. The container also optionally contains a cartridge containing chemicals which, when intermixed, result in an endothermic reaction. These chemicals are normally separated from each other by a membrane which, upon rupture of the membrane and insertion of the cartridge into the container, cools the contents of the container.
