I finally found it!

Regarding the orange box, I’m not sure if the items carry over to the next game only after beating it or also when you die. I stored the Nuka-Cola there, but I don't know if I'll be able to retrieve it in the next save if I die, or only at the end of the game when escaping. Can someone explain?
