If the food is packed tightly and any gaps filled with newspaper then it will act as it's own ice blocks but a few extra wouldn't hurt. How long it would stay frozen depends on the quality of the cool box and the ambient temp. I would expect it to stay frozen for at least 2 1\2 hours easily with a couple of ice blocks if it stays closed.
I have a couple of insulated picnic cool bags, not sure of the capacity but they're the size of shopping bags, I bought them from tesco.
I freeze a couple of two pinters of milk and use them as ice packs, and fill the bags to bursting with chilled stuff from the fridge. After four hours in the car the milk is still frozen solid. I don't use ice packs.
