Container deposit legislation Container-deposit legislation is any law that requires collection of a monetary deposit on soft-drink, juice, milk, water, alcoholic-beverage, and/or other reusable packaging at the point of sale. When the container is returned to an authorized redemption center, or to the original seller in some jurisdictions, the deposit is partly or fully refunded to the redeemer (presumed to be the original purchaser). It is a deposit-refund system.
