Drunkard creates pong emptying bottles (6)
I believe the answer is:
sponge
'drunkard' is the definition.
(I've seen this before)
'creates pong emptying bottles' is the wordplay.
'bottles' says the answer is hidden in the clue (bottling is a kind of containing).
'SPONGE' can be found hidden inside 'creates pong emptying'.
(Other definitions for sponge that I've seen before include "Porous mass for wiping up" , "Aquatic creature - cadge" , "clean with damp cloth" , "Piece of porous rubber" , "No pegs on this substance to soak up" .)
