Can upside down in cab accident, good insulated container (4,3)
I believe the answer is:
cool bag
'can upside down' is the definition.
The definition suggests a singular noun which matches the answer.
'cab accident good insulated container' is the wordplay.
I cannot really understand how this works, but
'good' could be 'cool' (similar in meaning) and 'cool' is located in the answer.
'container' could be 'bag' (bag is a kind of container) and 'bag' is located in the answer.
This accounts for all the letters.
This may be the basis of clue (or it may be nonsense).
'in' acts as a link.
Can you help me to learn more?
(Other definitions for cool bag that I've seen before include "Icebox" , "picnic accessory" , "Insulated container for food and drink from the fridge" .)
