Luggage Storage at CDG Paris

[Lora]

Hi again;

While my backpack will be small enough to go as carry-on, I will be taking liquids, toothpaste, swiss army knife, sunscreen etc which is no longer allowed as carry-on. I don't want to check my backpack, due to all the belts etc, so I figured out that I can take a small cheap suitcase and pack all that stuff in, including my backpack and check that in as luggage.

Is there a place at CDG where I can store the suitcase until I return. I am catching a train to Bayonne directly from CDG so will not be going anywhere else that may provide storage.
