Not prepared to put into a nicer, carved receptacle (9)
I believe the answer is:
container
'receptacle' is the definition.
(I know that receptacle can be written as container)
'not prepared to put into a nicer carved' is the wordplay.
'prepared' indicates anagramming the letters.
'to put into' is an insertion indicator.
'carved' is an anagram indicator.
'not' with letters rearranged gives 'ont'.
'a'+'nicer'='anicer'
'anicer' anagrammed gives 'cainer'.
'ont' inserted into 'cainer' is 'CONTAINER'.
(Other definitions for container that I've seen before include "Metal shipping box" , "Receptacle" , "tin can, say?" , "Vessel" , "Sort of ship" .)
