Container that cheats, maybe? (6)
I believe the answer is:
sachet
'container' is the definition.
(sachet is a kind of container)
'cheats maybe?' is the wordplay.
'maybe?' is an anagram indicator (I've seen 'maybe' mean this).
'cheats' is an anagram of 'SACHET'.
'that' is the link.
(Other definitions for sachet that I've seen before include "'Small soft packet, of pot-pourri perhaps (6)'" , "Package" , "Scent bag - shampoo envelope" , "'Small soft bag, for perfumed powder say (6)'" , "Small bag or sealed plastic pack" .)
