Legal Question in Credit and Debt Law in Iowa

I am not sure I understand the question, but I am guessing you want to place a container in a mall or park to collect cans. If so, I would say a mall is private property, so you have no right to place anything there without the mall owner's permission. Likewise, if you are planning to place this container in a public park, you would need the permission of the municipality which owns the park. I suppose it never hurts to ask, but I doubt that in either situation you will get the permission you need.
