Bottle or other vessel, put off to the periphery (8)
I believe the answer is:
decanter
'bottle' is the definition.
(I know that decanter is a type of bottle)
'other vessel put off to the periphery' is the wordplay.
'other vessel' becomes 'can' (type of container. I am not sure about the 'other' bit.).
'put off' becomes 'deter' (both can mean to discourage).
'to the periphery' means one lot of letters goes inside another (outside letters go round the periphery).
'can' going into 'deter' is 'DECANTER'.
'or' acts as a link.
(Other definitions for decanter that I've seen before include "Recanted about glass bottle for wine" , "Type of bottle" , "Stoppered glass container for alcohol" , "Glass container for table wine" , "Serving bottle for liquor" .)
