Vessel taking Joey out for a trip (3)

I believe the answer is:

urn

I'm a little stuck... Click here to teach me more about this clue!

'vessel' is the definition.
(urn is a type of container)

I don't understand how the rest of the clue works.

(Other definitions for urn that I've seen before include "Ornamental vessel" , "Vaselike vessel on a pedestal" , "A large vase, perhaps for holding ashes" , "Keats wrote an ode on a Grecian one of these" , "Tall stemmed vase" .)

I've seen this clue in the Evening Standard.
