Its contents go to pot (3,5)
I believe the answer is:
tea caddy
'pot' is the definition.
The definition and answer can be both man-made objects as well as being singular nouns.
Perhaps you can see an association between them that I can't see?
I can't explain the remainder of the clue.
Can you help me to learn more?
(Other definitions for tea caddy that I've seen before include "leaves container in the kitchen" , "Container for bags (or leaves)" , "Container for Earl Grey etc" , "source of refreshment?" , "drink dispenser" .)
