Cereal Container as Trash Can
It’s always wise to keep a trash bag in your car so you can dispose of used tissues and wrappers when people eat snacks in the car. You may find it useful to use plastic cereal containers in lieu of just a plastic bag floating around the backseat. These are designed to keep your cereal fresh, but they can also keep the smell of your trash contained. If you need to put something in the trash, just pop the top and close it up when you’re done. Just line it with a grocery bag and you should be good to go.
