A "carton" is a container made out of thick paper. The most common kind of carton is a milk carton, which is a tall rectangular box with a triangular top. Other things that come in cartons include:
- orange juice
- chinese food
- cigarettes (There are multiple packs of cigarettes in one carton.)
- beer (6 bottles of beer fit in one carton. Larger containers for beer are called "cases".)
These are all different shapes, but all classified as "cartons".
