Unfortunately I had festellen that with this box Henkel are both to open and close. I tried with my son (8years) at home to open and close. But I think that he certainly does not have the patience during the break, to lock the lid on the can in peace and then even both to push handle with downward force. I would have thought that one side is fixed and only 1 handle to press down. But yeah, I think certainly another possible use for the box.
