Coffin

A coffin was a container in which a non-incinerated body was placed after its death. Starfleet was known to use photon torpedo casings as coffins for space funerals. Starfleet customs mandated that the Flag of the be draped on the coffin after its closure. 

Also, many races, including the Mirak and several Federation species, buried its soldiers in dress uniforms along with any decorations they could have earned.
