Sugar container emptied daily (5)
I believe the answer is:
candy
'sugar' is the definition.
(thesaurus)
'container emptied daily' is the wordplay.
'container' becomes 'can' (can is a kind of container).
'emptied' means to remove the middle letters.
'daily' with its middle taken out is 'dy'.
'can'+'dy'='CANDY'
(Other definitions for candy that I've seen before include "Crystallised sugar; US sweets" , "American confectionary" , "Sugary sweet" , "American sweets" , "Girl's name (diminutive)" .)
