Whole eating from a plastic container that had 4 different pockets in it, I noticed that the liquid food tends to enter the grooves in the container. It got me thinking what is the purpose of these and why can’t there be containers that have a smooth interior?

Disposable containers need to be cheap, and the easiest way to make them cheap is to make them from a single piece of material that’s as thin as possible. The more materials used, the more complex the shape and the more amount of material used, the more expensive they become. Using a thin single piece of material allows for cheap and easy production, most are either stamped from a single piece or injection molded. Since the material is thin, in order for it to be structurally sound, using grooves and ridges make it stronger than it would be if it were just flat on all surfaces.
