He produces case of beer with container (6)
I believe the answer is:
brewer
'he' is the definition.
'case of beer with container' is the wordplay.
'case of' means to remove the middle letters (outsides of).
'with' is a charade indicator (letters next to each other).
'container' becomes 'ewer' (ewer is a kind of container**).
'beer' with its centre taken out is 'br'.
'br'+'ewer'='BREWER'
'produces' is the link.
(Other definitions for brewer that I've seen before include "one needing teapot?" , "Maker of beer - "Phrase and Fable" dictionary editor" , "who prepares the tea?" , "Maker of 22 Across" , "Tendency to seek perfection" .)
