Toothpaste container (4)
I believe the answer is:
tube
'toothpaste container' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for tube that I've seen before include "Hollow cylindrical object" , "Underground transport" , "Can of beer (colloquial)" , "Cylindrical hollow conduit" , "Pipe - railway" .)
