Tramp fills lots of paper bottles (9)

I believe the answer is:

rehoboams

'bottles' is the definition.
(I've seen this before)

'tramp fills lots of paper' is the wordplay.
'tramp' becomes 'hobo' ('hobo' can be a synonym of 'tramp').
'fills' means one lot of letters goes inside another.
'lots of paper' becomes 'reams' (I've seen this before).
'hobo' inserted within 'reams' is 'REHOBOAMS'.

(Another definition for rehoboams that I've seen is " Very large wine bottles".)

I've seen this clue in The Independent.
