Not sure what to say about the foam fear except set drinks at the bottom up right and let the ice melt sit below the top or the ice melt.
Foam fear?
You have never worked in the transportation or food service industry, have you?
Food, such as canned goods and perishables, and food grade items, things like plates, cutting boards, sandwich bags, cups, coolers, whatever, do not normally share adjacent trailer, container, or pallet space with things like solvents, fertilizers and pesticides. If they do, they are normally separated by other freight.
Non-food-grade items, like foam insulation, and reflectix and other items you might want to stuff into a cooler might very well have been shipped right next to a dirty pallet of cow manure, a leaky case of Round-Up, or a carton of aromatic muriatic acid or turpentine with a few leaking screw-on caps.
Plus those items from the hardware or sporting goods store will have been handled by LOTS of the dirty sweaty hands of store personnel and customers. It's not intended to be in direct contact with the food or ice that you will be consuming.
There is just no good reason to suggest that someone place this type of stuff into a cooler that will contain their food supply.
Food and water that you ingest should be kept separated from non-food containers and materials. Period.
