The open upper end and the cavity are dimensioned to receive a fluid container. The securing member is supported on the sleeve and is adapted to secure the sleeve tightly about fluid containers having different diameters. The light source includes a light bulb and a power source and is supported on the sleeve in a position to direct light into the cavity.
