Pack Reliant Robin, say and supply any rug (5,1,3)

'any rug' is the definition.
I know nothing about this answer so I can't judge whether this works.

'pack reliant robin say and' is the wordplay.
I cannot quite see how this works, but
'pack' could be 'carry' (synonyms) and 'carry' is found within the answer.
'and' could be 'n' (common abbreviation for 'and') and 'n' is found within the answer.
This may be the basis of the clue (or it may be nonsense).

'supply' is the link.

Can you help me to learn more?
