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

'tube' is the definition.
(tubular or cylindrical container)

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

(Other definitions for vial that I've seen before include "Bottle that contains a drug" , "Ampoule" , "Small container for liquid medicine" , "Small glass container" , "Not much bottle" .)

I've seen this clue in the Irish Times (Crosaire) and The Irish Times.
