'put away note during dinner at sea' is the definition.
I can't tell whether this defines the answer.

'note during dinner at sea' is the wordplay.
'note' becomes 'te' (musical note).
'during' indicates putting letters inside.
'at sea' indicates an anagram.
'dinner' anagrammed gives 'inrned'.
'te' placed inside 'inrned' is 'INTERNED'.
