You can't. A chest fridge/freezer becomes a gravitational singularity sucking random items from every corner of the kitchen to its lid. You can keep trying to return them to their rightful place but in the end it is a fruitless task as the rate of accumulation becomes faster than your speed of repatriation and the contents of the freezer are eventually lost to time behind the "event horizon" of its surface.
