Stop saving tin bottle (8)
I believe the answer is:
decanter
'bottle' is the definition.
(decanter is a kind of bottle)
'stop saving tin' is the wordplay.
'stop' becomes 'deter' (I've seen this before).
'saving' is an insertion indicator.
'tin' becomes 'can' ('can' can be a synonym of 'tin').
'deter' placed around 'can' is 'DECANTER'.
(Other definitions for decanter that I've seen before include "Stoppered liquor container" , "Recanted about glass bottle for wine" , "Vessel with stopper for serving wine" , "Glass spirits container" , "source of drink" .)
