Container of valuables secure and threats diverted (8,5)
I believe the answer is:
treasure chest
'container of valuables' is the definition.
'treasure chest' can be an answer for 'container' (treasure chest is a kind of container). I am not certain of the 'of valuables' bit.
'secure and threats diverted' is the wordplay.
'and' means one lot of letters go next to another.
'diverted' indicates an anagram (letters must be diverted to different positions).
'secure' put after 'threats' is 'threatssecure'.
'threatssecure' anagrammed gives 'TREASURE-CHEST'.
Can you help me to learn more?
(Other definitions for treasure chest that I've seen before include "Box for valued items" , "Pirate cargo" , "Typical pirate hoard" , "Box of wealth" , "Box holding items of great value" .)
