Children’s entertainer delivers party drink in these? (5,5)

I believe the answer is:

punch bowls

'party drink in these?' is the definition.

'children's entertainer delivers' is the wordplay.
'children's entertainer' becomes 'punch' (as in a Punch and Judy puppet show).
'delivers' becomes 'bowls' (to bowl is to deliver the ball in cricket).
'punch'+'bowls'='PUNCH-BOWLS'

I've seen this clue in The Guardian.
