Container that releases liquid in a fine spray (8)
I believe the answer is:
atomiser
'container that releases liquid in a fine spray' is the definition.
(I've seen this before)
This is all the clue.
(Other definitions for atomiser that I've seen before include "Device for reducing liquid to a fine spray" , "Dispenser for turning liquid into a fine spray" , "Fine spray producer" , "Device for making liquid into a fine spray" , "Mister" .)
