Sort dirty perfume bottles (4)
I believe the answer is:
type
'sort' is the definition.
(type is a kind of sort)
'dirty perfume bottles' is the wordplay.
'bottles' indicates a hidden word (bottling is a kind of containing).
'TYPE' is hidden in the letters of 'dirty perfume'.
(Other definitions for type that I've seen before include "Kind, model" , "Figure" , "Print - classification" , "Mark" , "Produce characters" .)
