Run off to get a receptacle (3)
I believe the answer is:
urn
'a receptacle' is the definition.
(I know that urn is a receptacle)
'run off' is the wordplay.
'off' indicates an anagram.
'run' is an anagram of 'URN'.
'to get' acts as a link.
(Other definitions for urn that I've seen before include "Samovar, perhaps" , "Vase-shaped vessel" , "Vase for containing ashes" , "Tall stemmed vase" , "Container for tea or ashes" .)
