The Torch Relay lantern will be used to store the Olympic flame. Its main purposes will be to receive the Olympic flame kindled in Olympia, to light the Olympic torch and to exhibit the sacred flame.

The International Olympic Committee (IOC) requires the flame remain lit during the entire course of the Torch Relay in order to protect the sanctity of the Olympic flame and the purity of the Torch Relay. If the torch flame should be extinguished, it must be relit using the mother flame stored in the lantern. This is to ensure that the flame used to light the Olympic cauldron at the Opening Ceremony comes from the sacred Olympic flame kindled in Olympia.

The inspiration for the original design of the Beijing Olympic Torch Relay lantern comes from the traditional lanterns used inside ancient Chinese palaces. The silver luster of the lantern coupled with crystal-clear glass serve as a foil to the flame and communicates the Olympic flame's sanctity and purity.
