Tapped item (3)
I believe the answer is:
keg
'tapped item' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for keg that I've seen before include "What's found at King's Head" , "Barrel as for beer" , "Small cask or barrel" , "Sort of beer" , "Small beer cask" .)
