No you have to wait until lvl 23/25 to open the cache. Just store it in your stash to prevent opening it by fault
The items in the cache will be based on the level you have been when you acquired them. At least it was so when I was keeping track of it.
So, I recommend keeping one bounty per act open till you get to a desired level and then do the last bounty in act + cache opening.
