Tottering, carried G&T in container (9)
I believe the answer is:
cartridge
'container' is the definition.
'tottering carried gt' is the wordplay.
'tottering' is an anagram indicator.
'carried'+'gt'='carriedgt'
'carriedgt' is an anagram of 'CARTRIDGE'.
'in' is the link.
(Other definitions for cartridge that I've seen before include "Tube of ink for fountain pen" , "Case for shot, ink, tape, etc" , "holds a lot of ink" , "round" , "Magazine" .)
